Why sleep sometimes eludes us Oct 19, 2024

Do you find it difficult to get a good night's sleep? If you do, you are not alone. According to the US National Institutes of Health, between 6 and 30 per cent of adults suffer from insomnia or lack of restorative sleep. Since the establishment of sleep medicine a century ago, we have learnt a lot about the causes of sleeplessness. And yet, as the continuing development of new sleep aids demonstrates, its prevalence remains high.

Persistent lack of sleep can have serious consequences for your health but despite this some writers, and other creative people, seem to welcome it. Franz Kafka famously claimed that if he couldn't pursue his stories through the night, they would "break away and disappear".

Iszi Lawrence discusses our changing understanding of insomnia, and its hold over our imagination, with Dr. Manvir Bhatia, the vice-president of Indian Society for Sleep Research; science journalist Kenneth Miller, author of Mapping the Darkness; the Scottish writer – and self-confessed ‘intermittent insomniac’ - A L Kennedy; and World Service listeners.

The high-speed train race Sep 21, 2024

The first public run of the Japanese ‘bullet train’, the Shinkansen, on the 1st of October 1964, captured public imagination worldwide. And it wasn’t just the train’s sleek look or its high speed that made the headlines. Behind the train’s futuristic exterior lay a whole host of engineering innovations: new pantographs, automatic signalling, revolutionary drive units. Since then, very fast train travel has become available in over a dozen other countries. Places such as China and Spain have overtaken Japan when it comes to top train speed or the extent of the high-speed network. But the recent rise in remote working has reduced the demand for business rail travel and commuting. So what does the future hold for high-speed rail?

Iszi Lawrence talks about the origins of high-speed rail and its current state to historian of modern Japan, Prof. Jessamyn Abel from Penn State university, civil engineering professor Amparo Moyano from the University of Castilla-La Mancha, Consultant Editor of the Railway Gazette Murray Hughes, poet Jan Ducheyne and World Service listeners.

The diary: A life page by page Aug 24, 2024

During the Covid-19 pandemic, many people found that keeping a diary was one way of reducing stress during uncertain times. They also felt that it was important to chart their day to day experience of a historic moment in world history. Such diaries will be valuable sources in years to come for historians, providing future scholars with a glimpse into the lives of ordinary people.

These diaries form part of a long tradition of people chronicling their own stories, whether intended for publication or purely to put thoughts down on paper. One of the earliest texts we could describe as a diary was written by the Roman emperor Marcus Aurelius, whose musings were influenced by Stoic philosophy. Later diaries, such as those by or the African American naval yard worker Michael Shiner or the teenage Anne Frank, have been important in helping us understand society and events from ‘the bottom up’ during a given period.

Iszi Lawrence explores what motivates people to keep diaries. She’s joined by a panel of experts including Dr Polly North, Founding Director of the Great Diary Project at Bishopsgate Institute in the UK; Julie Rak, the Henry Marshall Tory Chair in the Department of English and Film Studies at the University of Alberta who's an expert on what’s known as life writing; and Sergio da Silva Barcellos who’s published widely on diary keeping in Brazil, including a chapter in The Diary: The Epic of Everyday Life.

The only way is up: A history of mountaineering Jul 20, 2024

Humans have always co-existed with mountains, as ancient remains found in glaciers prove. But our interest in them may have been more spiritual or religiously motivated, rather than as a place to go to improve our health and wellbeing. In some cultures today, mountains are still considered to be the home of deities. So when did mountaineering become a popular pastime and how did the obsession with bagging summits start? Iszi Lawrence investigates our evolving relationship with the planet’s highest peaks.

Iszi is joined by Dawn Hollis, author of Mountains before Mountaineering: The Call of the Peaks before the Modern Age; Peter Hansen, Professor of History and Director of International and Global Studies at Worcester Polytechnic Institute in the US, and author of various books on mountaineering including The Summits of Modern Man: Mountaineering after the Enlightenment; and anthropologist and mountaineer Young Hoon Oh. The programme will also hear from blogger Andrew Szalay, otherwise known as the Suburban Mountaineer. And a range of Forum listeners from around the world contribute their personal experiences of mountains.

Music on the move Jun 15, 2024

Many of us remember the first portable music device we owned: a transistor radio, a boombox, a Walkman or perhaps an iPod. We might even recall the songs we played on it. But we might be less aware of how profoundly audio technology developments from the 1950s to 2000s changed the ways in which we consume music and other audio outside of the home or concert venue. Transistor radios allowed outdoor sounds and noises to mix and compete with those coming over the airwaves, creating new auditory experiences; the cassette player gave the listener a cheap way of making and re-making their own playlists; and the advent of digital music players encouraged us to ‘own’ music recordings without possessing a physical copy of the audio.

Iszi Lawrence discusses the history of portable music with Dr. Annie Jamieson, Curator of Sound Technologies at Bradford’s National Science and Media Museum; American drummer and writer Damon Krukowski; Dr. Jahnavi Phalkey, science historian and Founding Director of Science Gallery Bengaluru, India; Karin Bijsterveld, Professor of Science, Technology and Modern Culture at Maastricht University; and World Service listeners.

The fight for women’s education May 18, 2024

Among all the talk about ‘knowledge economy’ it is easy to forget that universal schooling is a relatively new phenomenon. Mandated first in a few European countries in the 18th century, it did not reach many others until the 20th. And the idea that women have an equal right to be educated frequently encountered stiff opposition, often from the privileged who feared that knowledgeable females would upset the social status quo.

Just about everywhere, the right to women’s education was hard won: for instance Bal Gangadhar Tilak, one of the influential leaders of Indian independence movement, campaigned vociferously for decades against sending girls to school, complaining that it would lead to increased competition for jobs and to women neglecting their ‘domestic duties’. Mary Carpenter, the acclaimed Victorian education reformer, maintained that neatness and needlework, rather than a full academic curriculum, were ‘essential to a woman’.

Fast forward to 2024 and even though the gap between male and female educational attainment has narrowed world-wide, there are still many places where women lag behind, even in something as basic as literacy. According to UNESCO, women today account for almost two-thirds of all adults unable to read.

So how did we get here? And how can we close this gap? Iszi Lawrence follows the story of women’s education with Jane Martin, Professor of Social History of Education at Birmingham University; Parimala V. Rao, Professor of the History of Education at Jawaharlal Nehru University in New Delhi; Dr. Karen Teoh, Associate of the Fairbank Center for Chinese Studies at Harvard and World Service listeners.

Feeding the world and the Green Revolution Apr 20, 2024

In February 2024, the renowned Indian geneticist Dr. MS Swaminathan was posthumously awarded the country’s highest civilian honour, the Bharat Ratna. This was in recognition of the dramatic increase in the yields of food staples, such as rice and wheat, that Indian agriculture experienced under his stewardship of the ‘green revolution’ in the 20th century. That revolution is credited with saving many people from hunger and malnutrition across Asia and Latin America. And yet, half-a-century on farmers’ incomes in Africa, Asia and Europe are falling and in many countries farmers are on the streets protesting. At the same time, the environmental impacts of intensive food production are becoming increasingly clear. So do we need a new ‘green revolution’? And is the use of the latest agricultural technology, from robots to AI the answer?

Rajan Datar discusses the past and present of food growing with Professor of Economics Douglas Gollin, crop scientist Professor Nigel Halford, historian of science Dr. Madhumita Saha, robotics project manager Andreas Hofland and listeners from around the world.

Etiquette Mar 16, 2024

‘Always pass the salt and pepper together, even if your fellow diner has asked just for one of them’. That’s the standard advice given by countless dining etiquette manuals, one of the many rules regarding proper manners that have been handed down from generation to generation. But what if some of the rules have become outdated, silly or just wrong? And why do we have etiquette in the first place? Where do the rules of polite conduct come from and are they the same the world over?

Iszi Lawrence follows the story of etiquette across time and over several continents with the help of Annick Paternoster, Lecturer at the University of Lugano in Switzerland who has a special interest in the history of politeness; Professor Daniel Kadar from Dalian University of Foreign Languages in China, the HUN-REN Hungarian Research Centre for Linguistics, and the University of Maribor in Slovenia; Courtney Traub, author and editor of the travel website Paris Unlocked; Japanese writer and cultural commentator Manami Okazaki; former Chief of Protocol at the Foreign Ministry of Grenada Alice Thomas-Roberts; and Forum listeners from around the world.

Supermarkets Feb 17, 2024

Supermarkets: they are ubiquitous yet hard to define, lauded and vilified in roughly equal measures, and in many countries they have a huge influence on what we eat. Technological innovations, big social changes and new shopping habits have all shaped their development and today’s megastores are a far cry from their small-scale ancestors of the 1930s. And yet, some quirks of supermarket design remain constant: for instance, why are the eggs always so hard to locate in the stores?

Iszi Lawrence navigates supermarket aisles with the help of historian and economist Marc Levinson; Aarti Krishnan, Lecturer in Sustainability at Manchester University; Simona Botti, professor of marketing at London Business School and Forum listeners from around the world.

Diplomacy Jan 20, 2024

In the 1990s, an advert for a brand of chocolate depicted a sophisticated gathering hosted by the foreign ambassador of an unspecified country. It hinted at a gilded existence of cocktail parties and small talk among influential, wealthy guests. Iszi Lawrence finds out how the stereotype of the diplomatic world compares with the reality of international relations. Who does the real work behind the scenes and who has the power? When we see powerful leaders on the world stage shaking hands and signing treaties, what has led up to that moment?

Iszi discusses first hand experiences of the diplomatic world with the American diplomat Maryum Saifee and the former High Commissioner of Maldives to the UK, Farah Faizal. They are joined by Dr. Lorena de Vita, a historian of diplomatic relations to explain how their work impacts all of us. Plus World Service listeners from across the globe share their thoughts on what diplomats actually do.

The story of throwaway living Dec 16, 2023

The humble plastic bag is actually a marvel of engineering: it is cheap, light, strong, waterproof and it has conquered the world. In countries where plastic bags have been banned, they are still being smuggled in. The environmental pollution and other problems that discarded plastic can cause has made it a focus of passionate debate. But is plastic really the problem or is it our increasing use of disposable and single-use items? The popularity of disposable products predates the invention of the plastic bag in the 1960s or even the advent of Western consumer society in the aftermath of the Second World War. And in the last three decades, so many new single-use items have been produced that we increasingly cannot imagine our lives without them, and not just in the festive season. So what is the way forward?

Iszi Lawrence talks about all manner of disposable and single-use objects with Jennifer Argo, Professor of Marketing at the School of Business, Alberta University; Mark Miodownik, Professor of Materials & Society at University College London; Katherine Grier, Professor Emerita of History at the University of Delaware and founder of the online Museum of Disposability; space archaeologist Dr. Alice Gorman from Flinders University in Australia and listeners from around the world.

Political parties and us Nov 18, 2023

Political parties come in all shapes and sizes and their ideas are just as varied. But what kind of parties best reflect 21st-century society? How do we, as voters, choose between them at elections? What are their ever-increasing expenses spent on? And - perhaps most importantly - how well do political parties respond to the needs and views of the public?

Iszi Lawrence discusses these questions with Professor Leonie Huddy from Stony Brook University who studies the psychology of politics, Associate Professor Karina Kosiara-Pedersen who researches party membership at the University of Copenhagen, Professor Paula Muñoz Chirinos who works on political finance at the University of the Pacific in Peru, Catherine Mayer co-founder of the Women's Equality Party in the UK, as well as student Luke Louis Ow from Singapore and other listeners from around the globe.

What makes a good boss? Oct 21, 2023

We can probably all think of examples of bad bosses – the people who we love to gossip about with our colleagues outside work. And even if you’re lucky enough to have had good experiences of management, you may be familiar with bad bosses from popular culture. But what makes a good manager and how can you inspire people in the workplace?

It’s a question that’s been debated since the Industrial Revolution when rapidly expanding companies needed a way of controlling their workers. From there developed various theories of management, some of which drew on aspects of sociology and psychology.

Rajan Datar is joined by Ann Francke, the chief executive of the Chartered Management Institute in the UK; Monica Musonda, the CEO of Java Foods in Zambia; and Todd Bridgman, Professor of Management Studies and Head of the School of Management at Victoria University of Wellington / Te Herenga Waka in New Zealand. We’ll also present a selection of comments and experiences sent in by Forum listeners.

The joy and sorrow of roads Sep 16, 2023

Whether we are pedestrians, cyclists or drivers, roads play a crucial role in our everyday lives. But where and how should we build any new ones? What kind of roads do we need? And how did we end up with the ones we have?

Rajan Datar talks about the past and present of roads and roadbuilding with anthropologist Traci Ardren from the University of Miami, civil engineer Kate Castle, historians Alexis DeGreiff from the National University of Colombia in Bogota and Aparajita Mukhopadhyay from Kent University, literary scholar Stephanie Ponsavady from Wesleyan University in Connecticut and journalist Karim Waheed from Dhaka. Plus World Service listeners from around the globe share their road-trip joys and frustrations.

Pets and us Aug 19, 2023

For every young American under the age of 18, there are about two cats or dogs receiving free food and lodgings in US homes and that pattern is replicated in many other countries. So why do so many of us keep pets? Why do we name them, consider them part of the family? Companionship, pleasure, status symbol and kinship with all life have been offered as explanations but it's easy to forget that mass keeping of pets - as opposed to working animals - is a recent development of the last two centuries or so.

Iszi Lawrence talks about our evolving relationship with pets with Dr. Anindita Bhadra from the Dog Lab at the Indian Institutes of Science Education and Research in Kolkata; Dr. Erin Hecht, evolutionary biologist from Harvard; Dr. Margo DeMello, anthrozoologist from Carroll College in Montana; writer and cultural commentator from Japan Manami Okazaki; Durham University historian Professor Julie-Marie Strange; and Rachel Williams, neuroscientist at UCL and comedian. We also sift through the dozens of comments and pet stories sent in by Forum listeners.

The evolution of teenagers Jul 15, 2023

In some ways the 21st century is a very unusual time when it comes to adolescence - a study in the US found that teenagers smoke less, drink less and have less sex than the previous generation. And worldwide young people are coming of age in a digital era, with the dangers and opportunities that represents. Our expectations of teenagers vary hugely depending on the social, historical and cultural context. Paleoanthropologist Ella Al-Shamahi takes us through the big evolutionary questions about adolescence: Why do humans go through this developmental stage? What's the point of all that teenage angst? And how come every generation stubbornly repeats the same mistakes?

She is joined by a panel of experts:

Laurence Steinberg is one of the world's leading experts on adolescence. He is Professor of Psychology and Neuroscience at Temple University in Philadelphia, USA. His latest book is called, 'You and Your Adult Child'.

Emily Emmott is a lecturer in biological anthropology at University College London. She's currently researching the implications of the social environment around us during our teenage years.

Jon Savage is a British writer and music journalist, best known for his history of the Sex Pistols and punk music. He's the author of 'Teenage: The Creation of Youth Culture'.

Brenna Hassett is a bioarchaeologist at University College London and the author of 'Growing Up Human: The Evolution of Childhood'.

Global mass tourism Jun 17, 2023

From Bhutan to The Bahamas and Iceland to Indonesia, mass tourism has grown at an unprecedented rate over the last few decades. Today’s top destinations are struggling with the sheer numbers of visitors and the United Nations has called for a total rethink on how the industry operates.

The origins of travel for pleasure go back centuries and package holidays in the 1960s made it accessible to many in the West but it’s only the combination of cheap flights and the advent of the internet that has led to truly global tourism on a mass scale. Whilst the industry now generates huge income for many companies and individuals around the globe, critics point to the cost to both the environment and humankind.

Drawing on listeners’ questions and comments, Rajan Datar examines the way mass tourism has impacted people’s lives, both positively and negatively, and asks if the enforced pause in tourism caused by Covid was utilised as an opportunity for a re-think. He is joined by Sihle Khumalo, a popular South African travel writer; Shazia Mirza, a renowned British comedienne and writer; Qupanuk Olsen, originally a mining engineer but now Greenland’s leading travel influencer; Prof. Noel Salazar, anthropologist of tourism from KU Leuven in Belgium; Iñigo Sánchez-Fuarros, senior researcher at the Institute of Heritage Sciences of the Spanish National Research Council and Dr. Birgit Trauer, tourism consultant and educator from Australia.

A deep dive into deepfakes May 20, 2023

Are we in a new age of information warfare? The technology to create deepfakes has progressed steadily over the past decade and enables anyone to create videos of people saying and doing things they didn’t actually say or do. But the idea of manipulating video to spread misinformation is almost as old as film itself.

Presenter Iszi Lawrence invites a panel of experts to tackle your questions about AI technology and the uses of deepfakes. Is this something we should be concerned or excited about? What can be done to detect and block malicious content? And what does this mean for our understanding of truth and reality?

Iszi is joined by Francesca Panetta, Director of the AKO Storytelling Institute at the University of the Arts, London; Joshua Glick, Visiting Associate Professor of Film and Electronic Arts at Bard College, NY and Samantha Cole, senior Editor at Motherboard/Vice and author of 'How Sex Changed the Internet'. We also hear from artist and technologist Halsey Burgund and from listeners Brandy and Ahmad.

How the mobile phone changed everything Apr 15, 2023

When telecoms engineer Martin Cooper first chatted in public on a mobile phone 50 years ago few would have predicted that this brief telephone call would be the start of a revolution that would change the lives of billions. Over the last half a century, the mobile has transformed not just how we communicate with each other but also how we view and interact with the world around us. However, recent research suggests that this may not all be for the best.

Drawing on listeners comments and questions, Rajan Datar explores what sets the mobile phone apart from previous communication devices. Why did SMS messaging take off so quickly after a slow start in the 1990s? And how did the morphing of a portable phone into a pocket computer a decade later lead to a situation where many people now interact with their phone more than with any human?

Rajan is joined by Scott Campbell, Professor of Telecommunications at the University of Michigan whose work focuses on meanings, uses and consequences of mobile communication in everyday life; behavioural psychologist Dr. Daria Kuss from Nottingham Trent University who specialises in cyberpsychology, technology use and addictive behaviours; and comedienne and PhD. candidate at Exeter University Helen Keen who is researching social connections at the Wellcome Centre for Cultures and Environments of Health. We also hear from educator Wong Fung Sing from Singapore and other listeners from around the world.

The submarine: Stealth machine Apr 13, 2023

Given the submarine's importance to many of the world's navies, it's perhaps surprising to learn that for many years it was considered an inventor's folly and of little use in maritime warfare. Indeed the submarine had a difficult birth because of the technical challenges involved in putting a moving vessel underwater, challenges that could only be overcome once the technology became available.

The submarine eventually proved its potential in World War I, where its ability to pass undetected ushered in a new era of ‘unrestricted warfare’. Since then, it has never looked back and today’s submarines are capable of remaining submerged for months at a time – the ultimate stealth weapon. As navies modernise, what has traditionally been an exclusively male service is now opening up to women in some countries.

Rajan Datar prowls the ocean's depths to find out more about the 'silent service', along with submarine designer Professor David Andrews from the Mechanical Engineering department of University College London; historian Axel Niestlé, author of German U-boat Losses in World War II; George Malcolmson, the curator of the British Royal Navy's submarine museum; and author Eric Wertheim, editor of the US Naval Institute’s reference book Combat Fleets of the World.

Hazel Scott: Jazz star and barrier breaker Apr 06, 2023

A child prodigy on the piano, then a glamorous jazz and popular music entertainer, a civil rights campaigner and the first black American woman to host her own TV show: for the first three decades of her life, Hazel Scott’s rise to fame was vertiginous.

Born in Trinidad in 1920, Scott was the headliner in some of New York’s most fashionable clubs by the time she was twenty. A couple of years later she became one of Hollywood’s highest paid entertainers and then married one of the most high-profile US Congressmen of her day. Their celebrity lifestyle regularly featured on newspaper front pages, Scott’s records were selling well and her syndicated TV show was given double airtime because it was so popular. And then, almost overnight, she vanished from public view. What happened? That's one of the questions Rajan Datar discusses with Scott's biographer and actor Karen Chilton; Loren Schoenberg, saxophonist, bandleader and Senior Scholar of the National Jazz Museum in Harlem; and playwright, lyricist and broadcaster Murray Horwitz.

The bittersweet tale of cocoa Mar 30, 2023

Do you like cocoa? You are in good company: in South and Central America people have been enjoying the fruit of the cacao tree - the source of cocoa, chocolate and much else - for thousands of years. Ancient empires fought battles for the control of the best trees, cacao beans were used as currency, and being able to make a tasty cacao drink could even save your life. To trace the history of cacao in Latin America, Bridget Kendall is joined by archaeologist Cameron McNeil, chef and food historian Maricel Presilla and geneticist and cacao researcher Juan Carlos Motamayor. The reader is Joseph Balderama.

The dam builders Mar 23, 2023

The Hoover Dam in the US, the Aswan Dam in Egypt and the recently opened, and sumptuously named, Grand Ethiopian Renaissance dam. Since modern times, huge mega dams like these to tame rivers, create water storage and hydropower, have become a symbol of nationhood used to create national pride and bolster political power, from the Cold War to today. Nehru, the first Prime Minister of India, called dams the temples of modern India. But dams have also been highly controversial, displacing rural populations, disrupting local ecology and more recently it’s been shown that dams can increase the amount of greenhouse gases in the earth’s atmosphere. So why are so many countries like China still highly involved in dam building, and will they need to change tack in the future? And, could the humble beaver offer a solution?

To discuss the past, present, and future of dam building, Rajan Datar is joined by Nikita Sud, Professor of the Politics of Development at Oxford University; Donald C. Jackson the Cornelia F. Hugel Professor of History at La Fayette University in the US and author of many books on the history of dam building, including Building the Ultimate Dam: John S. Eastwood and the Control of Water in the West; and Dr Majed Akhter, a political geographer who is senior lecturer in Geography at King’s College London. With the contribution of Dr Emily Fairfax, an ecohydrologist with an expertise in beaver activity and beaver dams from California State university Channel Islands in the US.

Alexander the Great or not so great? Mar 16, 2023

From Persia to India to Greece – they called him The Great – that is Alexander the Great. Also known as Alexander III of Macedon, he was one of the most successful military leaders of all time. Undefeated by the time of his death in 323 BCE, he is still a go-to figure when people want to define an empire builder. But how should we view this often cruel and destructive militarist today in the light of current world events? And, despite his brutality, like his ransacking of the beautiful capital city of Persepolis, is there a more progressive side to Alexander, his desire for cultural assimilation for instance, that explains why he became an inspiration not just to nationalists and imperialists but also to writers, poets, and the gay community?

To discuss the relevance of Alexander the Great today, Rana Mitter is joined by James Romm, Professor of Classics at Bard College in New York state whose latest book is Demetrius: Sacker of Cities, the failed but would-be successor to Alexander the Great; Dr Haila Manteghi from the University of Münster in Germany who’s the author of Alexander the Great in the Persian tradition; Ali Ansari, Professor of Iranian History at the University of St Andrews in the UK; and Meg Finlayson, a specialist on the evolution of the queer Alexander, from the University of Durham in the UK.

Rituals: Our anchors in a changing world Mar 09, 2023

From coronations to cup finals, many of us love a big event, a ceremony with age-old observances. Indeed rituals, whether public spectaculars or more personal ones, such as a particular daily routine, have been part of human experience since time began. But why do rituals persist even though so many of them seem to serve no obvious practical purpose? Rajan Datar looks for clues in our past with the help of Egyptologist Dr. Elizabeth Frood and historian of Venice Prof. Edward Muir. It turns out that non-human animals – for instance elephants - also display ritual-like behaviour and not always for practical reasons. We hear from a leading behavioural ecologist, Dr. Caitlin O’Connell-Rodwell. We examine whether rituals really do remain unchanging through time: it might seem to be their essential characteristic but in reality they continuously evolve. And what about the power of contemporary collective ceremonies and the strong emotions that swell inside us from being part of a huge crowd? Anthropologist Dr. Dimitris Xygalatas gives us his insights.

Tropicália: the movement that defied Brazil’s dictatorship Mar 02, 2023

Drawing on traditional music, pop culture, kitsch, rock and modernist poetry to mention just a few of their sources of inspiration, the short-lived Tropicália movement in late 1960s Brazil was provocative and anti-authoritarian. Perhaps most importantly it represented a uniquely Brazilian aesthetic that could only have emerged from that country’s specific culture and history.

The movement’s leading lights were eventually arrested by the military regime that governed Brazil at the time, and exiled to London. But Tropicália paved the way for other performers to demand artistic freedom.

With the help of musical examples, Rajan Datar and guests will explore what made Tropicália so disruptive. Joining Rajan will be singer Mônica Vasçoncelos and guitarist Gui Tavares, social scientist Professor Liv Sovik from the Federal University of Rio de Janeiro, who’s published widely on Tropicália, including a collection of essays entitled Tropicália Rex: Popular music and Brazilian culture; and David Treece, Emeritus professor of Portuguese at King’s College, London, who’s written extensively on Brazilian popular music, including the book Brazilian Jive: From Samba to Bossa and Rap.

How the shipping container changed the world Feb 23, 2023

Nearly everything we consume is transported by ship. The biggest container ships in the world are among the largest moving structures made by man and can carry over 24,000 20-foot container units. The standardisation of these simple metal containers in the 1950s and 60s marked a turning point in world trade, driving down costs and ultimately fuelling globalisation. Now that supply chains have become ever more complex and been put under increasing strain, we take a look at the history of the shipping container.

Joining Rajan Datar are Marc Levinson, American historian and economist and author of The Box: How the Shipping Container Made the World Smaller and the World Economy Bigger; Alan McKinnon, professor of Logistics at Kühne Logistics University in Hamburg and author of Decarbonising Logistics: Distributing Goods in a Low Carbon World; Yash Gupta, shipping industry expert with over 20 years’ experience in vessel management and logistics.

Neanderthals: Meet the relatives Feb 16, 2023

Developments in new technology such as DNA sequencing have transformed our understanding of the Neanderthals, one of a group of archaic humans who occupied Europe, the Middle East and Western Asia more than 300,000 years ago.

First identified by fossil remains in 1856 in a German quarry, the Neanderthals led an extremely physical existence as hunter-gatherers. They were stronger than us, adaptable as a species to huge variations in climate, with brains as large as ours and sophisticated ways of creating tools.

Many of us carry some of the DNA of Neanderthals, thanks to interbreeding with homo sapiens. Although the Neanderthals today are no longer with us, their story has a lot to tell us about ourselves and our future survival on the planet.

Rajan Datar is joined by Janet Kelso, a computational biologist and Group Leader of the Minerva Research Group for Bioinformatics at the Max Planck Institute for Evolutionary Anthropology. She specialises in the analysis of DNA sequencing of ancient people such as Neanderthals; Katerina Harvati, the Senckenberg Professor for Paleoanthropology and Director of the Institute for Archaeological Sciences at the University of Tübingen. Her work focuses on the origins of modern humans and Neanderthal evolution; and archaeologist and writer Rebecca Wragg Sykes, Honorary Fellow in the School of Archaeology, Classics and Egyptology at the University of Liverpool. Her award-winning book Kindred: Neanderthal Life, Love, Death and Art was published in 2020.

Cavalry and code-breaking: The Polish-Soviet war Feb 09, 2023

A Russian army stands at the gates of the capital of another country, a country that Russia has previously occupied and one that, according to Russian politicians, has no right to independent existence. Sounds familiar? That capital city was Warsaw and the year was 1920. But what happened in Poland just after the end of World War One bears strong similarities to what went on near Kyiv in 2022.

After the First World War, Russian Bolsheviks, and Lenin in particular, wanted to reoccupy Poland, and indeed Ukraine, Belarus and some other countries, so that they could serve as a bridge for exporting communist revolution to Western Europe. The Poles resisted even though at first they were outnumbered and outgunned by the Russians. The result was the Polish-Bolshevik war which was not fully resolved until 1921 and which had a big impact on the future shape of inter-war Europe.

To guide us through the Polish-Bolshevik war are three distinguished historians: Dr. Pawel Duber, researcher at Nottingham Trent University whose work focuses on Poland in the first half of the 20th Century; Anita Prazmowska, professor of International History at London School of Economics and the author of many publications on Polish history in the last century and beyond; Robert Service, emeritus professor of Russian history at Oxford University, whose books cover Russia from the Mongol conquest to Putin.

How we work: Redesigning the office Feb 02, 2023

The pandemic has made us all rethink how we work. Where once millions of people used to travel into work in tall glass buildings in big cities every day, now our idea of the office has come to include the kitchen table or maybe even a coffee shop. Yet despite the temptation to shift permanently to remote working, many organisations say the events of the past few years have actually underlined the importance of offices as spaces that connect people. So what are offices for? We are delving back into the history of the modern office to learn how past designs could help us in the future.

Presenter Rajan Datar is joined by three guest experts:

Nigel Oseland is an environmental psychologist and consultant at Workplace Unlimited in the UK. He's the author of Beyond the Workplace Zoo: Humanising the Office.

Jennifer Kaufmann-Buhler is Associate Professor of Design History at Purdue University in West Lafayette, Indiana. She's the author of Open Plan: A Design History of the American Office.

And Agustin Chevez is a workplace researcher and architect, and Adjunct Research Fellow at the Centre for Design Innovation at Swinburne University in Melbourne, Australia. He's the author of The Pilgrim's Guide to the Workplace.

When money died: The world's worst inflation Jan 26, 2023

In the summer of 1946 inflation in Hungary reached 41.9 quadrillion per cent. That’s 41.9 followed by 14 zeros – the highest rate of inflation ever recorded anywhere in the world. It meant prices of everyday goods and services doubled, on average, every 15 hours.

As the shattered country struggled to get to its feet after World War Two, weighed down by a Soviet occupation and punishing reparations, its government had little choice but to print more and more money, further fuelling the price spiral.

The hyperinflation stripped wages of almost all their value and plunged millions of Hungarians into a new fight for survival, but as they lost all faith in banknotes they turned to ever more inventive ways to trade and earn a living. We discuss how life for ordinary Hungarians changed amidst the chaos, what caused and eventually halted the economic disaster, and what the whole episode can tell us about the meaning of money.

Bridget Kendall is joined by Béla Tomka, professor of modern social and economic history at the University of Szeged, in Hungary; László Borhi, the Peter A Kadas Chair and associate professor in the Department of Central Eurasian Studies in the Hamilton-Lugar School at Indiana University, USA; and Pierre Siklos, professor of economics at Wilfrid Laurier University in Waterloo, Canada.

The writer Rachel Carson who fought insecticide wars Jan 19, 2023

Rachel Carson’s 1962 book Silent Spring has probably done more than any other to raise concerns about the damage that uncontrolled use of chemicals can cause to the natural world. Carson imagined a ‘silent spring’ in a world where birds no longer sang, killed off by indiscriminate spraying of pesticides. Her plea for caution when using insecticides led to major changes in government regulation of agrochemicals both in the United States and elsewhere.

So who was Rachel Carson? How did this scientist with a passionate interest in marine biology turn first into a best-selling author and then into an environmental campaigner? And - six decades on - have the warnings of Silent Spring been heeded?

Bridget Kendall is joined by Dr. Sabine Clarke, Senior Lecturer in Modern History at University of York with a particular interest in the history of synthetic insecticides; Michelle Ferrari, an award-winning film maker who directed a documentary about Rachel Carson's life for the American public broadcaster PBS; and Professor David Kinkela, an environmental historian and chair of the Department of History at Fredonia, State University of New York whose books include 'DDT and the American Century'. The reader is Ina Marie Smith.

Why do we have a seven-day week? Jan 12, 2023

Why do we divide our lives into 7-day chunks? Unlike the day, month or year, there’s no natural reason for this cycle, but nevertheless the week is now deeply ingrained in us and has proven very resistant to change.

We explore the pagan, religious and early scientific roots of this man-made rhythm, the ideological battles fought over it, and the reason why the number seven came out on top. Our expert guests explain where the names of our days come from, why the weekend was born, and how the week has come to dominate our economic and social lives.

There have, however, been several radical attempts to rip up the 7-day week – we hear about these alternatives and why they ultimately failed.

Rajan Datar is joined by Eviatar Zerubavel, distinguished professor of sociology emeritus at Rutgers University, New Jersey, and author of ‘The Seven-Day Circle: The History and Meaning of the Week’; Ilaria Bultrighini, honorary research fellow in ancient history at University College London; and David Henkin, professor of history at the University of California, Berkeley, and author of ‘The Week: A History of the Unnatural Rhythms That Made Us Who We Are’.

Forugh Farrokhzad: A trailblazing voice for women in Iran Jan 05, 2023

Forugh Farrokhzad burst into the public consciousness with a series of poems that sent shockwaves through Persian society in the mid-1950s. Her early poetry focused on the female experience and female desire, overturning – in the words of one biographer – 1,000 years of Persian literature.

Her critics sought to dismiss her skills as a writer by seeing her poetry purely as a confessional outburst of a divorced woman. That attitude has tended to overshadow her achievements, although her private life is so compelling it’s perhaps inevitable. Since her early death in a car accident, Forugh’s life and poetry have been inspirational for many Iranians, who see in her an artist who was prepared to defy authority and convention to speak out.

Bridget Kendall is joined by Sholeh Wolpé, a writer-in-residence at the University of California, Irvine. She’s a poet, playwright, librettist and translator of Forugh’s work; author Jasmin Darznik, associate professor and chair of the creative writing progamme at California College of the Arts. Her novel, Song of a Captive Bird, is a re-imagining of Forugh’s life inspired by her poetry, interviews and correspondence; and Levi Thompson, Assistant Professor of Persian and Arabic Literature in the Department of Middle Eastern Studies at the University of Texas at Austin. He’s the author of Reorienting Modernism in Arabic and Persian Poetry.

The Cynics: Counter-culture from Ancient Greece Dec 29, 2022

Today’s counter-culture and alternative movements question mainstream norms, such as putting too much value on material possessions. The Cynics, practical philosophers of ancient Greece and Rome, also rejected conventional desires to seek wealth, power and fame. They were not your usual kind of philosophers: rather than lecturing or writing about their ideas, they acted out their beliefs by denying themselves worldly possessions and tried to live as simply as possible. Their leader, Diogenes of Sinope, allegedly slept in a ceramic jar on the streets of Athens and ate raw meat like a dog, flouting convention to draw attention to his ideas.

So who were the Cynics? How influential was their movement? What made it last some 900 years? And why does the term 'cynicism' have a different meaning today?

Bridget Kendall is joined by three eminent scholars of Greek philosophy: Dr. William Desmond, Senior Lecturer in Ancient Classics at Maynooth University in Ireland and author of several books on the Cynics; Dr. Elena Cagnoli Fiecconi, Lecturer in Ancient Philosophy at University College London; and Mark Usher, Professor of Classical Languages and Literature at the University of Vermont and author of new Cynic translations into English.

Calories: How to fuel a human Dec 22, 2022

Calories are fundamental to the way many of us view food and our own bodies - you’ll find them on supermarket shelves, restaurant menus, and in cookbooks. But they didn’t start out that way.

Originally coined during the study of steam engines and industrial energy, the term ‘calorie’ was transformed into a measurement of food as ‘fuel’ for humans, influencing industrial, public health and even foreign policies for more than 100 years.

It’s also spawned a multi-billion dollar diet industry – we learn about the author whose battle with her weight introduced the world to calorie counting.

But should we be paying the calorie so much attention? There are growing concerns that it’s a misleading, perhaps even dangerous guide to how our bodies digest food and burn energy.

Bridgett Kendall is joined by Dr Giles Yeo, professor of molecular neuroendocrinology at the University of Cambridge and author of ‘Why Calories Don’t Count: How we got the science of weight loss wrong’; Adrienne Rose Bitar, a specialist in the history and culture of American food and health at Cornell University, New York, and author of ‘Diet and the Disease of Civilization’; and Nick Cullather, professor of history and international studies at Indiana University, Bloomington.

Belarus: The crossroads of Eastern Europe Dec 15, 2022

Belarusian lands have seen dramatic upheavals throughout the twentieth century and today, like its neighbour Ukraine to the south, Belarus finds itself on the cusp, in between the countries of the European Union on one side and Putin’s Russia on the other. While Belarus often features in the news, its history is less well known. So how far back does the story of Belarus go? How was its sense of national identity forged? And how did it survive the traumas and repressions that it has been subjected to by various invaders and imperial powers?

Three historians of Eastern Europe join Bridget Kendall to answer these questions: Dr. Nelly Bekus, Lecturer at the University of Exeter who studies post-Soviet nations; Dr. Natalya Chernyshova, Senior Lecturer in modern history at Winchester University who researches the 20th century in Belarus and beyond; and Dr. Andrej Kotljarchuk, Senior Lecturer at Uppsala University in Sweden who focuses on the Second World War in Eastern Europe.

Margaret Sanger: Mother of birth control Dec 08, 2022

Activist Margaret Sanger is responsible for one of the most significant medical and social changes of the 20th Century – giving women the means to control the size of their families.

The former nurse, who’d witnessed the aftermath of backstreet abortions and her own mother’s premature death after 18 pregnancies, founded the birth control movement in the United States and helped to spread it internationally. She was also instrumental in developing the pill, now one of the world’s most popular contraceptives.

Her campaign was enormously controversial – she faced fierce opposition from the Catholic Church and was arrested several times for breaking strict anti-contraception laws. And her legacy is contested today – her association with the then powerful eugenics movement has thrown doubt on her motives and drawn allegations of racism by some. Even Planned Parenthood, the organisation she helped create, has distanced itself from her.

Bridget Kendall discusses her inspiration and battle against the powerful status quo with Ellen Chesler, a biographer of Margaret Sanger from New York; Elaine Tyler May, professor of American studies and history at the University of Minnesota and author of America and the Pill: A History of Promise, Peril and Liberation; Sanjam Ahluwalia, professor of history and women’s and gender studies at Northern Arizona University and author of Reproductive Restraints: Birth Control in India, 1877-1947; and Dr Caroline Rusterholz, a historian of populations, medicine and sexuality at the University of Cambridge.

Alice Guy: The first female movie mogul Dec 01, 2022

In the late 19th Century, when the motion picture camera was invented and cinema was born, a young French woman called Alice Guy ended up becoming the first ever woman film-maker; rising from being a lowly young secretary to a prolific and pioneering director, producer and entrepreneur. Yet at her death in 1968, she was barely known, most of her thousand or so films had been lost and her crucial role in the history of the film industry was forgotten. In the past few decades, Alice Guy’s reputation has been gradually revived, and today she is recognised as a creative visionary and inspiration to many women film directors.

Joining Rajan Datar to track the career of Alice Guy, or Alice Guy Blaché as she was also known by her married name, is the film scholar, Dr Anthony Slide, the editor of The Memoirs of Alice Guy Blaché; Dr Alison McMahan, the author of Alice Guy Blaché: Lost Visionary of the Cinema, and the novelised biography WonderShadows; and Caroline Rainette who performed, wrote, and directed, Alice Guy: Mademoiselle Cinema. With the contribution of Pamela Green, the director and producer of Be Natural: the untold story of Alice Guy Blaché.

The Epic of Gilgamesh: A quest for immortality Nov 24, 2022

Unearthed from the ruins of ancient cities in modern-day Iraq, the reconstruction of the epic from fragments of clay tablets has been a labour of love for scholars of ancient Mesopotamia. This painstaking work has brought to life a sophisticated story of adventure, heroism and friendship, as well as a reflection on the human condition.

Today, experts are uncovering additional fragments of cuneiform script and using artificial intelligence to decipher the text and fill in the gaps of this and other stories. Professor Anmar Fadhil from the University of Baghdad tells the programme about the latest discoveries.

Bridget Kendall is joined by Andrew George, Emeritus Professor of Babylonian at SOAS at the University of London and author of an acclaimed English translation of the epic; Professor Enrique Jiménez, chair of Ancient Near Eastern Literature at Ludwig-Maximilians University in Munich, Germany who has published widely on Babylonian literature of the first millennium BC; and Dr Louise Pryke, Honorary Associate in the Department of Classics and Ancient History at the University of Sydney in Australia who is the author of Gilgamesh, a guide to the epic which was published in 2019.

Uruguay 1930: The first football World Cup Nov 17, 2022

As the spotlight falls on Qatar for the 2022 FIFA World Cup, we tell the story of how the world's biggest sporting spectacle began, in Uruguay in 1930.

How did a small South American nation of just two million people, thousands of miles from football's centre of power in Europe, come to launch this major global competition? We discuss the fractious international relations, the political cunning, and the sporting excellence behind the successful bid.

We learn how football helped shape a nation riven by civil war for much of its short existence, and hear about the tournament itself - the unfinished stadium, the dodgy refereeing decisions and, for some of the teams, the sheer ordeal of just getting there.

Rajan Datar is joined by Andreas Campomar, a writer and publisher from London and author of Golazo! A History of Latin American Football; Dr Philippe Vonnard, a historian specialising in the internationalisation of sport at the University of Fribourg and the University of Lausanne, both in Switzerland; and Brenda Elsey, a professor of Latin American sports and cultural history at Hofstra University, New York.

Moths: The story of the butterfly of the night Nov 10, 2022

The moth is an insect that’s almost 200 million years old. Throughout human history, its attraction to light, its amazing ability to camouflage, and its nocturnal activity have given rise to myths, spiritual beliefs and been the inspiration for art and literature – especially the genres of horror and the supernatural. In the natural world, moths also play a hugely important role in promoting global diversity as prolific pollinators. Yet, this ancient insect is often regarded as little more than the poor relation of the butterfly, an annoying creature that feeds on our favourite clothes and eats crops. Today, the moth is under threat from light pollution and climate change. So is it time we re-evaluate our views on moths?

Rajan Datar is joined by Professor Matthew Gandy, from the Department of Geography at the University of Cambridge in the UK; Dr Alma Solis, research scientist on moths for the US department of Agriculture, and curator at the Smithsonian Institution in Washington DC; Dr Franziska Kohlt, a post-doctoral research fellow at the University of York who has studied the history of insects in literature and science; and the Estonian artist Liina Lember, creator of a moths art installation. With the contribution of Shirley Camia, whose poetry collection is called “The Significance of Moths”.

The end of civilisation: Bronze Age collapse Nov 03, 2022

More than 3,000 years ago a group of powerful and intricately connected Mediterranean kingdoms collapsed over the course of just a few decades.

The palaces of Mycenaean Greece were destroyed, entire cities in Hittite Turkey were abandoned, and whole empires disintegrated. Some civilisations disappeared completely. But what caused the so-called Bronze Age collapse - climate change, trade breakdown, internal rebellion, or a mysterious group of invaders known as the ‘Sea Peoples'?

Some historians have called the aftermath a 'dark age', but was it really as gloomy as that, and might this period of wealth, pressure, and decline offer us any lessons today?

Rajan Datar is joined by İlgi Gerçek, assistant professor of ancient Near Eastern languages and history at Bilkent University, in Ankara; Eric Cline, professor of classics, history, and anthropology at The George Washington University, in Washington DC, and author of ‘1177BC: The Year Civilisation Collapsed’; and Marc van de Mieroop, professor of history at Columbia University, in New York.

From straw poll to opinion poll Oct 27, 2022

Today, we can’t imagine an election without an opinion poll gauging public opinion on who’s leading, who’s won a debate or who’s more popular with a specific group of voters. Even our favourite chocolate bars and footballers are subject to a poll. But how did straw polls evolve into the scientific number crunching we know now? What is their purpose and impact? How differently are they used around the world? And just how reliable are they?

Bridget Kendall is joined by economist and chairman of Gallup Pakistan, Dr. Ijaz Shafi Gilani; Scott Keeter, Senior Survey Advisor for the Pew Research Center in Washington; and Sir John Curtice from the University of Strathclyde.

Süleyman the Magnificent: longest-reigning Ottoman sultan Oct 20, 2022

The 46-year reign of Süleyman the Magnificent across central Europe, the Mediterranean and the Middle East was defined by territorial expansion and economic growth, as well as a flowering of art, architecture and culture.

The epithet ‘magnificent’ invites us to believe the Ottoman sultan could do no wrong. But he broke with precedent on several occasions and his private life came in for criticism. So how much does he owe his reputation to his advisers?

Bridget Kendall is joined by Gábor Ágoston, professor of history at Georgetown University in Washington DC and author of many books on the Ottomans, including The Last Muslim Conquest: The Ottoman Empire and Its Wars in Europe; Ebru Turan, assistant professor of History at Fordham University. She’s writing a book entitled Last World Emperor: The Origins of Ottoman-Habsburg Imperial Rivalry in the Apocalyptic Mediterranean, 1516-1527; and Marc David Baer, professor of International History at the London School of Economics and Political Science. He’s published widely on the Ottoman empire, including The Ottomans: Khans, Caesars and Caliphs, which was published in 2021.

William Cobbett: Champion of rural workers Oct 11, 2022

William Cobbett was a 19th century English writer, politician and campaigner, at a time when England was on the verge of riots and revolution, and many lived in extreme poverty. Born in 1763, Cobbett started off as a ploughboy, educated himself to run a best-selling newspaper, wrote beautifully accurate descriptions of the countryside which were to form his classic book Rural Rides, and later in life, even became a member of parliament. But it was for his sharp-tongued criticism of the British establishment that William Cobbett became most famous, exposing the corruption and hypocrisy of a system that favoured the rich over the poor, and in 1810, Cobbett was even jailed for his writings for two years, when he condemned the flogging of soldiers who were protesting about their pay. William Cobbett was often greeted by adoring crowds wherever he went, but some of his populist ideas and his dream of a return to an idealised vision of England’s past, also makes him a controversial and divisive figure today.

Joining Bridget Kendall is Ruth Livesey, Professor of English Literature at Royal Holloway, University of London; Dr Richard Thomas, chairman of the William Cobbett society and co-editor of “The Opinions of William Cobbett” with James Grande and John Stevenson; and Katharine Stearn, the editor of “Cobbett’s New Register” and lecturer on Cobbett for the Workers’ Educational Association. With the participation of Dr Mihika Chatterjee, lecturer in International Development at the University of Bath in the UK.

How the paparazzi transformed photojournalism Oct 06, 2022

They are the bane of every celebrity’s life: that pack of press photographers who stake out the homes, hotels and other haunts of the rich and famous in the hope of bagging a revealing and lucrative image to sell to newspapers and magazines around the world. Known as paparazzi, these photo journalists stop at nothing to catch their prey – climbing trees, hiding in cars and chasing after their quarry on motor scooters at high speed.

But where does the term ‘paparazzi’ come from? When did these celebrity snappers first appear? And why were the most famous of them almost all Italian to start with? To seek out the origins of the paparazzi, the Forum takes you back to the glitzy world of film stars in 1950s Rome.

Bridget Kendall is joined by Antonella Pelizzari, professor of the history of photography at Hunter College in New York and author of many books on Italian photography; the film critic Shawn Levy whose books include Dolce Vita Confidential about film and photography in 1950s Rome; and cultural historian and photographer Giuliana Minghelli whose books, including Stillness in Motion, look at the interaction between Italian film, photography and the wider arts world. With a contribution from cultural historian Luca Cottini from Villanova University. The readers are Giovanni Noto and David McGuire.

The Sun: Myths and magnetism Sep 29, 2022

The sun might not shape the pattern of our daily lives to the extent it did in the past. But understanding its behaviour is a focus of scientific research to grasp how activity on the surface of the sun - such as geomagnetic storms - can affect life on earth. "Space weather" can take out whole power networks, damage satellites and disrupt communication lines – the technology on which so many people rely.

Bridget Kendall and guests examine the sun's impact throughout history, and discuss what we know about its internal structure and magnetic fields.

Claire Raftery is a solar physicist and the Head of Education and Outreach at the National Solar Observatory in Boulder, Colorado; Philip Judge is a senior scientist at the High Altitude Observatory also in Boulder, Colorado. He’s written many papers on aspects of solar physics, as well as a book entitled The Sun: A Very Short Introduction; and philosopher Emma Carenini is the author of The Sun: Myths, History and Societies which considers how the sun has shaped philosophy and thought.

A forgotten founder of climate science: Eunice Newton Foote Sep 21, 2022

Eunice Newton Foote was the first person to suggest that an atmosphere rich in carbon dioxide would lead to a warmer planet, but her discovery was largely ignored and her name disappeared for more than 150 years. She fell into such obscurity that there’s no known picture of her.

Bridget Kendall explores the life of this American scientist and inventor and asks why her ground-breaking research, carried out in the 1850s, was overlooked for so long. Discrimination against women, especially in the sciences, was a major reason, but might a transatlantic power struggle and even a case of intellectual theft have played their parts?

Eunice was also one of the founding members of the women’s rights movement in the United States – we discuss how she helped launch a campaign that would eventually win women the right to vote.

Plus, the story of how her work was recently re-discovered, and the quest to ensure her name gains greater recognition.

Dreams: Prophecy, propaganda and psychoanalysis Sep 14, 2022

The images, sensations and emotions we experience during sleep were once seen as the gateway to the gods and had the power to alter lives and even whole societies.

Rajan Datar explores the way dreams, and their interpretation, have shaped beliefs and actions for thousands of years – from their role as a connection to the dead and the spirit world, to their ability to predict the future.

We hear how these seemingly involuntary visions inspired key historical figures, changed the course of major events, and were used by many rulers as a propaganda tool.

Plus, we discuss what’s really happening in our brains when we have dreams and ask whether 21st-century life is placing them under threat.

Yves Saint Laurent: Fashion revolutionary Sep 08, 2022

Since his death in 2008, the impact of designer Yves Saint Laurent on women’s fashion remains undimmed. The pea coat, the trench, the trouser suit – many of his designs are now staples of the modern Western woman’s wardrobe. So how did this famously shy and retiring man achieve global success? And did his fashion innovations for women shape social change in the 1960s, or were they a response to his times?

Bridget Kendall looks back at Saint Laurent’s life and legacy with former director of the Yves Saint Laurent Museum, Olivier Flaviano, fashion historian Emilie Hammen and one of Saint Laurent’s last assistants, designer Charles Sébline. First broadcast in 2018.

Brazil's Palmares: A beacon of freedom Sep 01, 2022

As Brazil celebrates 200 years of independence from Portugal, we look at the 17th-century community of people seeking freedom from slavery in the north-east of the country known as Palmares. It lasted longer and was larger than other settlements of this type and it withstood repeated attempts by European colonialists to destroy it.

So how did Palmares keep going for over a century when so many other communities like it in Latin America vanished after a few years? Who were the inhabitants? And what do we really know about them when there is no reliable history of the settlements: almost all the surviving documents are from people intent on destroying Palmares.

To help us sift through what we do know about Palmares, Bridget Kendall is joined by archaeologist Professor Pedro Paulo Funari from the University of Campinas in Brazil; Dr. José Lingna Nafafé, Senior Lecturer in Portuguese and Lusophone Studies at Bristol University; and Dr. Maria Fernanda Escallon, Assistant Professor in the Department of Anthropology at the University of Oregon. The reader is Natan Barreto.

Bluegrass: Virtuoso music of Appalachia Aug 25, 2022

It is rare in music history that scholars can point to the beginning of a particular style, but bluegrass would appear to be the exception to the rule. Mandolin player Bill Monroe from rural Kentucky had so much clout in the music business that some scholars have suggested that it was he who defined the sound which came to be known as bluegrass. He was certainly protective; Monroe is quoted as saying “the biggest job of bluegrass is to keep out what don’t belong in it.”

Played initially in America's rural south, bluegrass was later adopted by the counter-cultural college kid scene in the 1950s and '60s. And today the music is flourishing all over the world in the most unlikely places.

Rajan Datar is joined by Dan Boner, director of the Bluegrass, Old-Time, and Roots Music Studies programme at East Tennessee State University, who demonstrates how bluegrass works; writer and historian Tony Russell, whose publications on music include Rural Rhythm: The Story of Old-Time Country Music in 78 Records; and Dr Lydia Hamessley, professor of music at Hamilton College whose research concentrates on old-time and bluegrass music. She is the author of Unlikely Angel: The Songs of Dolly Parton.

The Art of War: Ancient Chinese guide to victory Aug 17, 2022

The Art of War is one of the most important military strategy texts ever written, and it has become just as influential, perhaps even more so, in the worlds of business, sport, and politics.

Bridget Kendall learns what the 2,000-year-old treatise has to say about deception, spying, and ruthlessness, and asks why it has come to be viewed as a guide to success in life in general.

But has it been misunderstood? We discuss whether it’s better viewed as a guide to avoiding war and conflict, rather than a manual for how to fight.

Plus, we try to get to the bottom of who really wrote it and learn about the blood-soaked period of Chinese history in which it’s believed to have been created.

Gandhi: Architect of Indian independence Aug 10, 2022

Mohandas K Gandhi’s decades-long campaign against British rule was the driving force behind Indian independence in August 1947.

The way he did it - through ‘satyagraha’, or non-violent resistance - made him one of the most famous and revered thinkers of the 20th century, and has inspired protest movements around the world.

Rajan Datar explores the experiences, ideas and people that turned Gandhi from a timid schoolboy and failed lawyer into a man bold enough to take on the might of the British Empire.

Plus, we ask whether he achieved the kind of Indian independence he really wanted, and find out why his legacy is the subject of intense debate in India to this day.

Making scents: The story of perfume Aug 04, 2022

Throughout history, fragrance has been used to scent both the body and our surroundings. With just one drop, perfume has the potential to stir memories, awaken the senses and even influence how we feel about ourselves. But what’s the story behind this liquid luxury in a bottle, now found on the shelves of bathrooms and department stores worldwide?

In this programme, Bridget Kendall and guests explore the modern history of perfume, including its flowering in France and the explosive chemical discoveries that helped to make fine fragrance what it is today. They also explore perfume’s ancient roots and ask: what’s in a name?

Bridget is joined by scientist and critic Luca Turin, writer and curator Lizzie Ostrom and the perfumer Thomas Fontaine. Also featuring William Tullett and James McHugh.

Eleonora Duse: The first great modern actress Jul 28, 2022

Eleonora Duse was an actress ahead of her time. As a performer in the late 19th century when elaborate gestures, exotic costumes and lavish decors were the norm, Eleonora Duse stunned audiences with her truthfulness and intense absorption in the characters she played. She wore no make-up, you could see her blush or turn pale, she was a master of subtle body language and vocal modulation, and her aim was to eliminate the self and become her characters. Today she is often credited with having inspired modern acting, and the Russian theatre director Stanislavsky saw her as the perfect actress, and was greatly influenced by her when he created his acting method. Born in 1858 in what is now northern Italy, Eleonora Duse started acting at the age of four years old with her family’s touring theatre troupe. By her twenties, working as both a theatre manager and a performer, she began to achieve worldwide popularity, travelling all over the world, from South America to Russia to Egypt. She was soon acknowledged as one of the greatest actresses of her generation and her independent lifestyle turned her into an early feminist icon. So what was the secret of her genius and why is she largely forgotten today? And with no recordings of her voice, how do we know she was such a great performer?

Joining Bridget Kendall is Dr Anna Sica, Professor of Theatre at the University of Palermo in Italy, author of The Murray Edwards Duse Collection, and D’Amore e D’Arte, the letters written to Duse from her Russian lover Alexander Wolkoff, soon to be published in English. Professor Paul Fryer, the co-editor of an essay collection on Eleonora Duse and Cenere (Cenere is the Italian word for Ashes, the title of the silent film Duse made in 1916, and the only record of Duse actually performing). Paul Fryer also directs the Stanislavsky research centre at the University of Leeds. And Dr Enza de Francisci, lecturer in Translation studies at the University of Glasgow, who specialises in the critical reception of Duse’s plays, and is the author of A 'New' Woman in Verga and Pirandello: From Page to Stage.

The reader is Cecilia Gragnani.

La Malinche: Mexico's great 'traitor' Jul 20, 2022

In Mexico the name La Malinche has become synonymous with treachery and betrayal - it even forms one of the country’s most vicious insults. Some have described its owner, an indigenous slave who became the interpreter and mistress of conquistador Hernán Cortés, as the most hated woman in Mexico’s history.

But by helping the Spanish topple the Aztecs in the early sixteenth century was she really guilty of selling out her own people, or simply doing everything she could to survive? Might we credit her with limiting the lives lost in the bloody conflict – one she knew her people could not hope to win?

Bridget Kendall explores the little-known life, and hotly-contested legacy of one of the most controversial figures in Latin American history, and the role she played in the meeting of the Old World and the New.

We hear how La Malinche’s story, and motives, have been re-interpreted over the last 500 years, and learn why she remains important in discussions of national identity, gender, culture and politics in Mexico to this day.

Taras Shevchenko: The slave who became a symbol of Ukrainian independence Jul 14, 2022

There are hundreds of monuments to the poet and painter Taras Shevchenko not just in Ukraine but all over the world. It is hard to overstate the importance of Shevchenko for most Ukrainians. For them he is not just the national poet who breathed new life into the Ukrainian language but a symbol of their country’s independence. His words kept the national spirit alive during the decades of forced Russification in the 19th Century and they found renewed resonance during the 2014 Maidan uprising. But Shevchenko's work is less well known beyond eastern Europe.

To remedy this Bridget Kendall is joined by Ukrainian writers and literary scholars Olha Poliukhovych from the National University of Kyiv - Mohyla Academy and Mykhailo Nazarenko from Taras Shevchenko Kyiv National University, and by professor of Slavonic studies at Vienna University Michael Moser. The reader is Ivantiy Novak.

The unstoppable orange Jul 07, 2022

Oranges have long represented love, wealth and status - since they originated in South East Asia, around the 8th Century BCE. The orange tree's ability to carry fruit and blossom at the same time made it a symbol of fertility and purity in religious art and painting, and the intoxicating fragrance of the blossom, the perfect sphere of the mature fruit and its sensuously refreshing taste inspired writers and artists, as well as growers to produce ever more spectacular creations. With the advent of artificial refrigeration in the 19th Century, oranges then became big business and widely available to all. By the mid 1880’s it’s said more than 2.5 million cases of Italian citrus fruit arrived in New York every year. Today, while oranges are enjoyed by many, their production also has a bitter side – the sad plight of many of the orange pickers, and the impact of the orange juice industry affecting the diversity of orange trees and profit margins of the growers.

Joining Bridget Kendall is Cristina Mazzoni, professor of Romance Languages and Cultures at the University of Vermont, and the author of Golden Fruit: A Cultural History of Oranges in Italy; the food and travel writer Clarissa Hyman, who has written Oranges: A Global History; and Dr Alissa Hamilton, the author of Squeezed: What You Don’t Know About Orange Juice.

Radio waves and plants: The life of JC Bose Jun 30, 2022

Sir Jagadish Chandra Bose was a polymath: a physicist, biologist and early writer of science fiction. He pioneered the investigation of radio and microwave optics. He made significant contributions to plant science, designing ingenious devices to measure plant growth and responsiveness. He founded one of India’s oldest and most distinguished research institutes. During his life he was honoured at home and in Britain he was knighted for his achievements and made a Fellow of the Royal Society. So why, outside India and his native Bangladesh, is J C Bose not better known?

Bridget Kendall asks four historians of science: Bose's biographer Subrata Dasgupta from Lafayette in the United States where he is emeritus professor at the University of Louisiana; Christin Hoene who is assistant professor at Maastricht University in the Netherlands where one of her research interests is the cultural history of radio in colonial India; author, film-maker and historian of science Jahnavi Phalkey who is the Founding Director of Science Gallery in Bangalore, India; and James Poskett who is associate professor at the University of Warwick and author of Horizons: A Global History of Science. The reader is Madhav Vasantha.

Samurai: Japan’s elite warrior class Jun 23, 2022

The reality behind the stereotypical image of Japan’s fearsome elite warriors is more nuanced than we are led to believe. It is thought the samurai developed as a social class in medieval Japan, when the term could encompass lowly foot soldiers or mercenaries, and often untrustworthy ones at that. A far cry from the skilled fighters who supposedly pledged undying loyalty to their lord, and followed a code of honour.

In fact, it was during peacetime that the image of the samurai came to be defined when their role as warriors was no longer necessary. During Japan’s aggressive imperial expansion in the early 20th Century, the samurai ideal was once again manipulated for nationalistic purposes.

Rajan Datar’s guests include Michael Wert, who has published several books on Japan’s warrior class, including Samurai: A Concise History. He is associate professor of East Asian History at Marquette University in Milwaukee; Marcia Yonemoto, professor and hair of the Department of History at the University of Colorado Boulder. She is the author of The Problem of Women in Early Modern Japan, which examines the role of women in Japan’s military-bureaucratic state; and Polina Serebriakova, whose doctoral thesis at the University of Cambridge in the UK focuses on warrior leaders in medieval Japan.

Ice cream: A cool history Jun 15, 2022

There are almost as many ice cream origin stories as there are flavours, but where did the frozen treat really come from, and who invented it?

Rajan Datar explores the dessert’s murky history, from the harvesting and flavouring of snow in China and the Middle East thousands of years ago, to the experimental kitchens of the European aristocracy.

Ice cream’s evolution has, of course, closely followed that of refrigeration – we learn why salt was crucial for keeping early versions cold, and hear about the daring entrepreneur who began the global ice trade. Plus, who really invented the ice cream cone? Producer: Simon Tulett

The Popol Vuh: Central American epic that survived Spanish conquest Jun 09, 2022

Mythological sagas are often fantastical and push the imagination to the limit but the Popol Vuh, which originates in what is Guatemala today, has a gallery of extraordinary characters both good and bad. They get involved in a series of mind-boggling battles and challenges and this eventually leads to the creation of the human race. The Maya K’iche’ story of the Popol Vuh has come down to us in an 18th-Century transcription and Spanish translation by a priest called Francisco Ximenez, and as with many ancient stories, there are tantalising questions about the history of the manuscript and the origins of the tale itself.

Rajan Datar traces the meanings and significance of the Popol Vuh with the help of Frauke Sachse who is director of Pre-Columbian Studies at the Dumbarton Oaks Research Library and Collection in Washington DC; Iyaxel Cojti Ren, professor at the University of Texas; Allen Christenson who is professor at Brigham Young University in Provo, Utah as well as an ethnographer and author of a new translation and critical edition of the Popol Vuh. The reader is Florencia Cordeu.

The Koryo Kingdom: Medieval dynasty that united Korea Jun 02, 2022

Today Korea is divided between North and South, but the founding of the Koryo Kingdom in the 10th Century was the first time the peninsula was truly united and when a sense of nationhood emerged. The Koryo Kingdom is remembered for some of the finest cultural achievements in the country’s history; it developed the world’s first printing press – 200 years before the German inventor Johannes Gutenberg came up with his own version, and it is also a period marked by beautiful ceramics and art. But what is less well known is how progressive its politics and society were; promotion was based on merit, women were given greater rights, and monarchs ruled through co-operation. It was also a turbulent time with personal intrigue and back stabbing at court, and constant threats of foreign invasion.

Rajan Datar finds out more about the Koryo Kingdom. He is joined by Sang’ah Kim, the Korean Collections’ Curator at the British Museum in London; Dr Charlotte Horlyck, reader in Korean Art History at SOAS, University of London, who has written about the collecting of Koryo Art in the early 20th Century; Edward (Ned) Shultz, professor emeritus in Asian Studies at the University of Hawaii, and Dr Juhn Ahn, associate professor in Buddhism and Korean studies at the University of Michigan in the United States and author of Buddhas and Ancestors: Religion and Wealth in 14th Century Korea.

Insulin: The discovery that transformed diabetic care May 26, 2022

The story of the discovery and development of insulin is a tale full of twists and turns, Nobel prizes and fierce rivalries. Scientists in the late 19th Century established the connection between the pancreas and diabetes, isolated the hormone insulin, and even patented the extract that lowered blood sugar. But it was not until a Canadian team published results in 1922 of their attempts to inject insulin into a patient that diabetes was transformed from a fatal condition to a manageable one.

Bridget Kendall is joined by science historian Dr Alison Li, who has studied the life of one of insulin's early pioneers in her book J.B. Collip and the development of medical research in Canada; Dr Viktor Joergens, a retired diabetologist who for more than two decades was the executive director of the European Association for the Study of Diabetes. He is also the co-author of Unveiling Diabetes: Milestones in Diabetology; and Dr Kersten Hall, visiting fellow in the Department of History and Philosophy of Science at the University of Leeds, and the author of Insulin - The Crooked Timber: A History From Thick Brown Muck to Wall Street Gold.

Eunuchs and empires May 19, 2022

Since ancient times the practice of castrating pre-pubescent boys, and sometimes men, was thought to make them loyal servants, suitable for roles at the heart of many imperial courts. Some historians believe this began with human slaves who were treated in the same way as animals – as lesser beings to be managed and controlled – with no free choice.

The effects of castration on the male body – the loss of testosterone being the principal one – had a huge impact on how eunuchs have been viewed throughout history. Being unable to father children who could threaten lines of succession, certain eunuchs rose to power precisely because of their exclusive access to the inner workings of empires. Castrated men were also prized for their singing voices in 17th and 18th century Europe, as Dr Brianna Robertson-Kirkland explains.

Bridget Kendall discusses this painful episode with Norman Kutcher, Professor in the Department of History at the Maxwell School at Syracuse University in the US. He specialises in imperial Chinese history, and he’s the author of Eunuch and Emperor in the Great Age of Qing Rule; Dr Kathryn Reusch, conservation technician at the Denver Museum of Nature and Science, who's published widely on the topic of castration in relation to archaeological remains; and Shaun Tougher, Professor of Late Roman and Byzantine History at Cardiff University. He’s written many books and articles on eunuchs, including The Roman Castrati: Eunuchs in the Roman Empire.

Vikings and their quest for silver May 12, 2022

Vikings were addicted to silver; they collected it as coins, as ingots, arm-rings, jewellery. On one Swedish island alone archaeologists and metal detectorists found some 200,000 silver coins and there is a silver hoard there for almost every Viking farm. Why? What can the coins, many of which came from Asia, tell us not just about the huge Viking trading area but also about their society? And how did this influx of silver transform European economy and life in the early Middle Ages? These questions have occupied historians and archaeologists for a long time but now advanced scientific techniques such as DNA analysis and microscopic laser sampling are yielding new, more detailed and sometimes surprising answers.

Rajan Datar gets an update on Viking research from archaeologist Marianne Hem Eriksen from the University of Leicester; Anders Winroth, historian from the University of Oslo; Soren Sindbaek, archaeologist from Aarhus University; and sound archaeologist Rupert Till from Huddersfield University.

Fertiliser and poison gas: The legacy of chemist Fritz Haber May 04, 2022

German chemist Fritz Haber's discovery of how to turn atmospheric nitrogen into ammonia is seen as one of the most significant of 20th century science - it enabled the industrial manufacture of fertilisers, which now provide food for up to half the planet's people.

But he was also responsible for the development and deployment of poison gas on the battlefields of World War One and is remembered by some as the 'father of chemical warfare'. His was also a life touched by personal tragedy and a struggle against a Jewish heritage that at first threatened to hold back his career, and would later send him into exile.

Bridget Kendall examines a life that epitomises science’s capacity to create and to destroy.

Emperor Nero: Bad boy of Ancient Rome Apr 28, 2022

Nero fiddled while Rome burned, didn’t he? At least, that’s what the history books tell us. Nero’s image as a depraved tyrant has been handed down to us by three biased sources, written after the emperor’s suicide in 68AD. These sources have informed interpretations of Nero’s legacy ever since, so much so that his involvement in the Great Fire of Rome has become a meme.

Recent scholarship has sought to rehabilitate Nero to a certain extent, to try to understand him in the context of his time. He was indeed a man who succeeded in shocking the Roman elite, but also someone who could strike a chord with the public and was well thought of outside the centre of political intrigue.

Rajan Datar attempts to separate fact from fiction, with guests Dr Ginna Closs, Associate Professor of Classics at the University of Massachusetts Amherst in the US and author of While Rome Burned: Fire, Leadership, and Urban Disaster in the Roman Cultural Imagination which was published in 2020; and Dr Evan Jewell, Assistant Professor of History at Rutgers University, Camden. He’s writing a book entitled Youth and Power: Acting Your Age in the Roman Empire; and Dr Shushma Malik, Senior Lecturer in Classics at the University of Roehampton. She’s the author of The Nero-Antichrist: Founding and Fashioning a Paradigm.

Mirror Mirror on the wall: The history of the looking glass Apr 21, 2022

For the Ancient Egyptians they were seen as receptacles for the soul, for the Aztecs they were used to tell the future and for the early Christians, they were an aid for reaching self-knowledge. And mirrors’ key role in the reflection of light led to the development of high-powered telescopes to explore the universe. No human invention has been so closely tied with our sense of self and the world around us. And yet mirrors also have a capacity to deceive us – so how much attention should we give them in our lives, and are we overly obsessed with our image in the mirror?

Joining Rajan Datar to find out more about the history of mirrors is Dr Elizabeth Baquedano, a specialist in the indigenous cultures of Mesoamerica and Senior Honorary Lecturer at the Institute of Archaeology, University College, London. Dr Franziska Kolt, a post-doctoral research fellow in the history of science at the University of York in England, who’s written Alice Through the Wonderglass: the Surprising Histories of a children's classic. And Mark Pendergrast, the author of Mirror Mirror: a history of the human love affair with reflection. With the contribution of Professor Serpil Bagci from Hacettepe university in Ankara in Turkey.

Kwame Nkrumah: Ghana’s Pan-African idealist Apr 14, 2022

Kwame Nkrumah was considered by some as a visionary hero who urged would-be leaders in Africa to embrace the idea of unity for the continent, and led Ghana to independence from British colonial rule in 1957.

But in becoming Ghana’s first prime minister, and then president, he was criticised for his autocratic style of government and the way in which he pursued his Pan-African ideology seemingly at the expense of his own people. In 1966 Nkrumah was removed from power in a coup, and never returned to Ghana.

Bridget Kendall’s guests include Ghanaian journalist-turned-historian, AB Assensoh, who interviewed Nkrumah in exile. Assensoh is emeritus professor of African American and African Diaspora Studies at Indiana University, Bloomington, and Courtesy Emeritus Professor in the History Department of University of Oregon. He’s the author of many books on Nkrumah, including a collaboration with his wife Yvette entitled Kwame Nkrumah’s Political Kingdom and Pan-Africanism Reinterpreted, 1909–1972. Joining them are Kwasi Konadu, Professor in Africana & Latin American Studies at Colgate University in the US. He’s published widely on African history, including The Ghana Reader: History, Culture and Politics; and Matteo Grilli, senior researcher at the University of the Free State in South Africa. He’s the author of Nkrumaism and African Nationalism: Ghana’s Pan-African Foreign Policy in the Age of Decolonization.

The Truman Doctrine: Beginnings of the Cold War Apr 06, 2022

President Harry Truman's address to the United States Congress, and the world, in March 1947 is seen by some historians as marking the start of the Cold War.

In it, the President committed the USA to the role of defender of global democracy, and pledged to contain the expansion of the Soviet Union and the spread of communism. The Truman Doctrine, as it became known, led to the establishment of NATO and, later, US involvement in conflicts in Korea and Vietnam.

But, as Bridget Kendall discovers, the speech and the policy it set out were by no means inevitable - both were shaped as much by misunderstandings and exaggerated fears as they were conflicting ideologies and the actions of the former World War Two allies.

Margaret Fuller: Early feminist and war correspondent Mar 31, 2022

In in her 1843 essay The Great Lawsuit, the American journalist and early feminist Margaret Fuller forcefully argued for the rights of women to work, think and live on their own terms, not just as companions and foils for men. She was one of the first Americans to do so. Fuller was a pioneer in other respects too: a trail blazer for advocacy journalism and for unrestricted female education. In the 1840s she became the first paid US war correspondent, reporting from Rome besieged by the French army.

Fuller packed a lot into a life of just 40 years; so much so that after her tragic death in a shipwreck, the men around her - some of them rather famous - did their best to diminish her memory. They exaggerated what they saw as her personal failings and in some instances even falsified her record. As a consequence, we are still discovering the true extent of her life and work.

Bridget Kendall talks to three Fuller experts: Megan Marshall, Professor at Emerson College in Boston whose book Margaret Fuller: A New American Life won the Pulitzer Prize for Biography; Professor Katie Kornacki, Chair of the English department at Caldwell University in New Jersey and the founding editor of the Margaret Fuller Society's Conversations magazine; and the cultural critic Judith Thurman, staff writer for the New Yorker magazine and an award-winning biographer focusing on female authors.

Money: From coin to cryptocurrency Mar 20, 2022

From Mesopotamian loan records which are over 4,000 years old to the cryptocurrencies of today, money has been with us for a long time. But how did we get from exchanging bits of metal or cowrie shells to the algorithmic trading of shares? Why did paper money originate in Song-dynasty China? Why was the Gold Standard adopted in the 19th Century? And what is money anyway? These are some of the questions that Bridget Kendall investigates with the help of three financial historians: Ute Wartenberg, president of the American Numismatic Society; William Goetzmann, professor of Finance and Management Studies at Yale University; and Christian de Pee, professor of History at the University of Michigan. They also answer listeners' questions about the history of finance.

Pinocchio: The real story of the mischievous wooden puppet Mar 17, 2022

Pinocchio is a cultural icon. He is the wooden puppet who can talk and walk. A cheerful headstrong character who keeps breaking the rules, and whose dream is to become a real boy. His story has been the subject of many retellings, and his growing nose when he lies has become a way to satirise politicians the world over. But Pinocchio’s origins are largely unknown outside Italy, and couldn’t be more different from his portrayal in the 1940 Disney film.

The original novel The Adventures of Pinocchio by the 19th century Italian writer Carlo Collodi is much darker and brutal, and originally ended with Pinocchio’s execution, but it was also a way of educating the children of a newly unified Italy. The actual literary text also provided a model, which is still used today, for a more standardised form of the Italian language. So why has Collodi’s original – which is one of the most translated books in the world and one of the most adapted – been largely ignored and why should we go back to it?

Joining Bridget Kendall is Dr Katia Pizzi, the director of the Italian Cultural Institute in London, who is the editor and co-author of Pinocchio, puppets and modernity: the mechanical body; Cristina Mazzoni, Professor of Romance Languages and Cultures at the University of Vermont, and editor and translator of The Pomegranates and other Modern Italian Fairy Tales; and Dr Georgia Panteli, Lecturer in Film and Comparative Literature at the University of Vienna and University College London, and author of From Puppet to Cyborg. Pinocchio’s Posthuman Journey.

The readings from The Adventures of Pinocchio were by Marco Gambino.

The invention of numbers Mar 10, 2022

Try and imagine a world without numbers. Telling people how many siblings you have, counting your wages or organising to meet a friend at a certain time would all be much more difficult. If you’re reading this on a digital screen, even these words are produced through a series of zero and one symbols. We take them so much for granted yet some cultures don’t count and some languages don’t have the words or symbols for numbers. This programme looks at when and why humans first started start to count, where the symbols many of us use today originate from and when concepts like zero and infinity came about.

Joining Bridget Kendall to explore the history of numbers and counting are anthropological linguist Caleb Everett from the University of Miami, writer and historian of mathematics Tomoko Kitagawa, and Emeritus Professor of Mathematics at Warwick University in the UK, Ian Stewart.

Vincent van Gogh: The struggling artist Mar 03, 2022

The Dutch post-Impressionist painter Vincent van Gogh is one of the most influential painters in western art. His series of still life sunflowers are known around the world today but during his lifetime in the 1800s he lived in poverty, selling very little of his work, some say just one painting, and suffered several serious breakdowns. One of his most famous works, The Starry Night, is said to be the view from his room in a French psychiatric hospital where he’d admitted himself shortly after severing his own left ear. This programme looks at the man behind these iconic paintings, explores how and why he became a painter and picks apart the various theories around his death from a gunshot wound at the age of just 37. Joining Bridget Kendall to discuss van Gogh’s life and work are Louis van Tilborgh, Senior Researcher at the Van Gogh Museum in Amsterdam and Professor of Art History at the University of Amsterdam; van Gogh biographer and co-author of Van Gogh: The Life, Steven Naifeh; and British art historian Lucrezia Walker.

Franz Liszt: Hungarian pianist and painter in sound Feb 24, 2022

A proud Hungarian by birth, Franz Liszt was a pioneer both in his piano playing and in his compositions. He was also the nearest thing to a rock star that classical music had in the 19th century. Fans would reportedly swarm over him, try and grab his gloves, even smoke his discarded cigars! Liszt lived up to his public image in his private life, with hectic touring schedules and colourful relationships with numerous women. But he was also generous to a fault – for example, frequently teaching for free - and he was a great champion of other composers.

Rajan Datar is joined by three people for whom Liszt and his music occupy a central position in their professional lives: Dr. Rena Mueller, a musicologist emerita at New York University who is working on a complete thematic catalogue of Liszt's music; Dr. Éva Polgár who teaches at Azusa Pacific University in California and is a pianist noted for her championing of not just Liszt's works but all the music from her native Hungary; and professor Kenneth Hamilton, Head of School of Music at Cardiff University, who is not just a distinguished pianist but also an author and broadcaster.

Examples from Liszt’s works used in the programme: Mazeppa (S.138) played by Leslie Howard Totentanz performed by Krystian Zimerman , Boston Symphony Orchestra, Seiji Ozawa La Campanella (Études d'exécution transcendente d'après Paganini, S.140) played by Leslie Howard Apparition No. 2 played by Ashley Wass Sonetto 123 del Petrarca (Années de pèlerinage II) played by Wilhelm Kempff Chase Neige (12 Études d'exécution transcendante, S.139) played by Boris Berezovsky Wilde Jagd (Études d'exécution transcendante, S.139 ) played by Daniil Trifonov Mazeppa (orchestral version, S. 100) performed by Wiener Philharmoniker, Giuseppe Sinopoli Ballade No. 2 played by Kenneth Hamilton Hungarian Rhapsody No. 2 played by Arcadi Volodos Csardas Obstinée played by Éva Polgár Les jeux d'eaux à la Villa d'Este (Années de pèlerinage III) played by Egon Petri

Joseph Heller's Catch-22: A novel of twisted logic and absurd bureaucracy Feb 17, 2022

"That’s some Catch, that Catch 22". It’s a novel that gave rise to a new term in the English language and gave voice to American soldiers serving in Vietnam in the 1960s. Since its publication in 1961, Catch-22, Joseph Heller’s best-selling novel, has not only come to symbolise the cynical self-serving aspect of war run as a business, but also the way an ordinary person can be trapped and controlled by bureaucracy and social rules, in whatever area of life. It’s a novel that’s sold tens of millions of copies, and it continues to engage new readers. So, what is the secret of its success? Bridget Kendall is joined by the American novelist and friend of Joseph Heller, Christopher Buckley; Dr Beci Carver, lecturer in 20th century literature at Exeter University, whose forthcoming book is Modernism’s Whims; and Tracy Daugherty, author of Just One Catch: A Biography of Joseph Heller, and Emeritus Professor at Oregon State University in the US. With the contribution of Patricia Chapman Meder, the author of The True Story of Catch-22, whose father was the inspiration for Colonel Cathcart, Heller’s commander who kept increasing the number of flight missions. Produced by Anne Khazam for the BBC World Service.

Sofya Kovalevskaya: The eventful life of a maths pioneer Feb 10, 2022

If you were a woman in the mid-19th century, some universities might let you attend public lectures on science, but very few would enrol women as regular students. The number of women allowed to sit exams and get academic degrees was vanishingly small. In mathematics it was almost unheard of. But the Russian mathematician Sofya Kovalevskaya changed all that. She was one of the first women in modern Europe both to gain a doctorate in mathematics and become a tenured professor. She was also the first woman to be part of the editorial committee of a leading mathematics journal and the publicity around her achievements helped pave the way for women to play a greater role in university life. Above all, she was an outstanding mathematician with at least one theorem bearing her name still used to this day.

So how did Kovalevskaya do it? How much was talent? How much luck and opportunity? And how much just sheer force of character?

To guide us through Sofya Kovalevskaya’s eventful life - and her equations – Bridget Kendall is joined by three experts: Ann Hibner Koblitz, professor emerita at Arizona State University and the author of A Convergence of Lives: Sofya Kovalevskaya - Scientist, Writer, Revolutionary; June Barrow-Green, professor of the history of mathematics at the Open University in the UK and chair of the International Commission on the History of Mathematics; and Elena Arsenyeva, associate professor at St. Petersburg State University in Russia and the coordinator of the Leonhard Euler International Mathematical Institute.

Machu Picchu: Secrets of a forgotten city Feb 03, 2022

The ancient Inca town Machu Picchu is now the most visited tourist attraction in Peru – and yet it lay nearly forgotten for over three centuries until American and Peruvian explorers drew the world's attention to it in the 1910s. And despite a century of excavations at the site, there are still many unanswered questions about Machu Picchu: why was it built in the first place, who were the immigrants that made up a large proportion of the town’s population, and why was it abandoned so quickly.

To find out more about Machu Picchu, Bridget Kendall is joined by leading archaeologists of the Inca civilisation Lucy Salazar and Michael Malpass, the celebrated mountaineer and explorer Johan Reinhard and by writer Mark Adams who retraced the steps of the 1911 expedition led by Hiram Bingham that put Machu Picchu back on the map.

Pleasure and pain: The philosophy of Jeremy Bentham Jan 27, 2022

How do you approach the decisions you make in life? Do you think about them in terms of the maximum pleasure and minimum pain that any choice would lead to for yourself and others around you? If so, you are beginning to think along similar lines to the influential British philosopher and reformer Jeremy Bentham with his concept of Utilitarianism. This was not Bentham’s only contribution to radical thought. With the prison and judicial systems, with education, women’s suffrage, animal rights and the monarchy, throughout his life he came up with a huge body of work that challenged the status quo and still feels relevant today. Rajan Datar is joined by three expert guests to guide us through the life and work of this remarkable thinker: professor Philip Schofield from University College London who is both the director of the Bentham Project and the general editor of the Collected Works of Jeremy Bentham; Emmanuelle de Champs who is professor of British history and civilisation at CY Cergy Paris University, and Jeffrey Kaplan who is assistant professor of philosophy at the University of North Carolina, Greensboro.

Copper: From mining to microprocessors Jan 20, 2022

Copper is a metal that has been with us since the dawn of civilisation. The Romans used it to build their empire, and its high thermal and electrical conductivity led to the 19th century discovery of how to generate electricity and a revolution in telecommunications. Copper was even used to build the Statue of Liberty in New York, and it’s because of copper’s tendency to oxidise that the statue is no longer shiny brown but green. Today we still depend on this 'eternal metal', so called because it doesn’t decay or rust, and it has become a staple and necessary component in new green technologies like solar power and electric cars. But extracting copper has always been very damaging to human health and the environment - so how has our relationship with copper changed over the centuries?

Joining Rajan Datar to find out more about copper past and present is Nikita Sud, Professor of Development studies at Oxford University and the author of The Making of Land and The Making of India; the archaeologist Dr William Parkinson, who is a curator at the Field Museum, and Professor of Anthropology at the University of Illinois at Chicago; and Andrea Sella, Professor of Chemistry at University College, London. Produced by Anne Khazam for the BBC World Service.

Writer Agatha Christie: Murder and mystery Jan 13, 2022

Agatha Christie put her decision to become a writer down to a lack of education and a capacity for day-dreaming. Her murder mysteries, full of ingenious plot twists, are still regarded by many as the finest examples of crime fiction and have sold in their billions in the English language and in translation.

Although the world she depicts is considered by some to be cosy and genteel, and her plots formulaic, a new generation of screenwriters is bringing out the darker side of Christie’s imagination. So what accounts for her continuing global success, when today’s crime fiction tends to be grittier and more realist?

Bridget Kendall is joined by Dr Michelle Kazmer, Professor in the School of Information at Florida State University, who’s combined a lifelong passion for crime fiction with study into how we use information – such as clues or evidence; Dr Mark Aldridge, Associate Professor of Film and Television at Solent University and the author of Agatha Christie on Screen and Poirot: The Greatest Detective in the World; and James Prichard, Agatha Christie’s great-grandson. Award-winning crime writer Ragnar Jónasson also explains how Agatha Christie's novels influenced his own work.

Boudica, warrior queen Jan 06, 2022

Boudica, also known as Boadicea, was a member of Iron Age aristocracy in Roman occupied England and her husband was the ruler of the Iceni people. When he died in around 60AD, Boudica, driven by Roman brutality, led a rebellion against the Roman army and marched on London. It was a ferocious attack that nearly drove the Romans out of Britain before Boudica was finally defeated. Today, she is an iconic and sometimes controversial figure. To explore Boudica, Bridget Kendall is joined by professors Richard Hingley and Miranda Aldhouse-Green and Dr. Jane Webster.

Harry Houdini: Escape artist and showman Dec 30, 2021

Harry Houdini’s story is the classic American tale of an immigrant who from impoverished beginnings made it big in the United States. Perhaps it is this early hand to mouth existence in a large family which explains his extraordinary drive to succeed. Captivated by magic shows, he began performing tricks on stage with one of his brothers, and then with his wife.

Houdini’s decision to make escape the focus of his act was well-timed, chiming with the public mood for sensational trickery. Whether it was escaping from handcuffs, a straitjacket or from a box filled with water, Houdini wowed audiences with his seemingly death-defying performance. So what motivated this complex man who spent a lifetime ‘deluding’ the public with his illusions, and how did he reconcile that with his campaign against the Spiritualist movement which he regarded as a racket?

Rajan Datar charts the life and career of the legendary Houdini, with writer and biographer Adam Begley, whose book Houdini: The Elusive American was published in 2020; Dr Matthew Solomon, Associate Professor at the University of Michigan and the author of Disappearing Tricks: Silent Film, Houdini, and the New Magic of the Twentieth Century; and Dr Katharina Rein from the University of Potsdam in Germany, who’s published widely on stage magic in the 19th and early 20th centuries, including Techniques of Illusion which will be available in 2022.

Antarctic Treaty: Protecting the icy continent Dec 23, 2021

It’s widely regarded as the most successful treaty in the world, and it was the first arms control agreement established during the Cold War. The Antarctic Treaty, which came into force in 1961, protects what is one of the most unspoilt places on earth, from mining, from military activity and allows only scientific exploration and peaceful pursuits. It was thanks to the treaty and research carried out in Antarctica that scientists identified a hole in the ozone layer in the 1980s, but it’s been most powerful as a symbol of what can be achieved to create peace between nations and give wilderness protection. So what has made this treaty so effective, and can it still hold up today in a world which is hungry for minerals and where an increasing number of states are seeking to project their technological and scientific prowess in Antarctica?

Joining Bridget Kendall is Birgit Njaastad, the Chair of the Committee for the Environmental Protection of the Antarctic, and for more than 25 years a Norwegian Polar Institute environmental expert; Professor Alan Hemmings, a specialist on the geopolitics of the Antarctic from the University of Canterbury New Zealand; and Dr Jessica O’Reilly, Associate Professor of International Studies at Indiana University in Bloomington in the United States, and the author of The Technocratic Antarctic. With poetry and song about the Antarctic by the New Zealand poet Bill Manhire. Produced by Anne Khazam for the BBC World Service.

Don Quixote: Spanish masterpiece Dec 16, 2021

With its multiple narrators, superb and complex characterisation, the influence of Don Quixote de la Mancha has been acknowledged by great writers through the ages as a masterpiece, and hailed as one of the most important novels in the history of literature.

On the surface the novel appears to be a comedy – of situation, of language and of character – but its author Cervantes succeeds in making Don Quixote so much more than a series of slapstick episodes. It was written during a particularly turbulent time in Spanish politics, when both Jews and Muslims were expelled from the Iberian peninsula, and this finds its way into the novel.

Bridget Kendall explores the tale of the self-styled knight Don Quixote and his sidekick Sancho Panza with Cervantes experts Ruth Fine, the Salomon and Victoria Cohen Professor in Iberian and Latin American Studies at the Hebrew University of Jerusalem; Carolyn Nadeau, the Byron S. Tucci Professor of Hispanic Studies at Illinois Wesleyan University; and Edwin Williamson, the King Alfonso XIII Professor Emeritus of Spanish Studies at the University of Oxford.

Algae: Slime life Dec 09, 2021

They’re slimy and slippery. They’re part of the green film you see on garden ponds. They can clump together and wash up on the shores of beautiful beaches. A lot of them are invisible to the naked eye. These underappreciated organisms called algae are indispensable to the presence of life on earth but not all is straightforward about them. They can be single celled or multi cellular. They can be ugly and slimy or sometimes beautiful: indeed are even a tourist attraction. They may be found in the sea or on land. They can be life-creating and yet life-destroying and toxic in excess. So perhaps it’s time we paid more attention to algae and their evolution. Rajan Datar is joined by Ruth Kassinger, author of Slime: How algae created us, plague us and just might save us; Dr Brenda Soler-Figueroa, a marine scientist at the Smithsonian Environmental Research Centre; Dr Gothamie Weerakoon Senior Curator of Lichens and Slime Moulds at the Natural History Museum of London and author of Fascinating Lichens of Sri Lanka; and Stefan Bengtson, emeritus professor at the Swedish Museum of Natural History.

The original Goths Dec 02, 2021

The Goths were a Germanic tribe infamous for their brief sack of Rome in 410 AD but their cultural and political influence was felt throughout Europe for centuries. They re-shaped the Balkans, preserved the Roman way of life in Italy and presided over a cultural flourishing in Spain. But how, many centuries after their demise, did they come to give their name to an important architectural style in medieval Europe and, in the 20th century, to a subculture popular all over the world?

Bridget Kendall talks all things Gothic with David Gwynn, historian at Royal Holloway, University of London, and author of Goths, the Lost Civilisation. Also on the panel are Janina Ramirez, a cultural historian, broadcaster and author who focuses on the Middle Ages, based at the University of Oxford, and Mischa Meier, professor of ancient history at the University of Tubingen in Germany.

Laskarina Bouboulina, the mother of modern Greece Nov 25, 2021

The 1821 Greek war for independence from the Ottoman empire became an inspiration for people all over Europe who wanted to dismantle the old multi-ethnic empires. But it is less well known that a number of women played key roles in the uprising. In this programme, Bridget Kendall and guests focus on Laskarina Bouboulina, perhaps the best known of Greek women freedom fighters. For the last two centuries, Bouboulina's deeds as as a brave sea captain and a generous financier of the uprising have enthralled people in Greece and elsewhere but how many of these stories are based in fact? And what is the significance of Bouboulina today?

To find out Bridget is joined by: Dr. Margarite Poulos, a historian of modern Greece from Western Sydney University whose book Arms and the Woman surveys the role of Greek women in the country's military struggles; Dr. April Kalogeropoulos Householder from University of Maryland, Baltimore County, who has not only written about Laskarina Bouboulina but also made a documentary film about her; and Pavlos Demertzis-Bouboulis, who is a descendant of Bouboulina as well as the director of a museum dedicated to her on the island of Spetses.

Mary Somerville: The queen of 19th-Century science Nov 18, 2021

For someone who was largely self-taught, Mary Somerville's rise to renown in the male-dominated world of science was quite remarkable. Although women were barred from being members of the learned societies where knowledge was shared in the early 19th-Century, Somerville found alternative ways to become one of the most respected figures in maths and science of her day.

Scottish-born Somerville played a crucial role in communicating the latest findings in science through a series of successful books. She regretted never making any original discoveries herself however, so does her experience suggest we should re-evaluate the role of originality in science?

Bridget Kendall is joined by Jim Secord, emeritus professor of History and Philosophy of Science at the University of Cambridge, who has edited the works of Mary Somerville; Dr Brigitte Stenhouse, lecturer in the History of Mathematics at the University of Oxford whose doctoral thesis looked at the mathematical work of Mary Somerville; and Ruth Boreham, former project curator at the National Library of Scotland, who is writing a biography of Mary Somerville.

The Malayan Emergency Nov 11, 2021

One of the earliest Cold War conflicts was a 12-year guerrilla war commonly known as the Malayan Emergency and fought from 1948 in the jungles of what is now Malaysia. This communist insurgency was fuelled not only by ideology but also by the desire for Malayan independence from British colonial rule. There have been a number of books and documentaries devoted to the subject but relatively few in English capture the experiences of the Chinese community in Malaya that was at the centre of the Emergency.

Rajan Datar is joined by three guests, all with family links to the Emergency: Sim Chi Yin, a photographer and artist from Singapore whose book She Never Rode that Trishaw Again tells the story of her grandmother widowed during the war in Malaya; Show Ying Xin, a postdoctoral fellow at the at the Australian National University’s Malaysia Institute in Canberra; and Rachel Leow, Associate Professor in Modern East Asian History at the University of Cambridge and author of Taming Babel: Language in the Making of Malaysia.

The Devils: Dostoevsky’s novel of political evil Nov 04, 2021

The Devils, The Possessed, or Demons, as it’s also known in translation, is Fyodor Dostoevsky’s most political novel but it’s also his bleakest and funniest. It’s a hundred and fifty years since its publication and two hundred years since its author’s birth. The novel tells the story of a group of young revolutionaries who run riot in a small provincial town in Russia, all under the indulgent eye of their elders, the liberal and progressively minded elite. It is a grim prophecy of totalitarian rule in the 20th century in what is a penetrating psychological study of the human consequences of extreme philosophical ideas.

Joining Bridget Kendall to discuss Dostoevsky and his novel The Devils or Demons, is Tatyana Kovalevskaya, Professor at the Russian State University for the Humanities in Moscow and the author of the bilingual edition Fyodor Dostoevsky on the Dignity of the Human Person; Carol Apollonio, Professor of the Practice of Slavic and Eurasian Studies at Duke University in the United States and President of the International Dostoevsky Society; and Dr Sarah Hudspith, Associate Professor in Russian at the University of Leeds, and author of Dostoevsky and the idea of Russianness. Produced by Anne Khazam for the BBC World Service.

A focus on spectacles Oct 28, 2021

If you had to name the innovations that have transformed human civilisation, you might suggest the printing press or the Internet, but the humble pair of spectacles has also revolutionised the way many of us experience the world. It's said that an astonishing three quarters of those in the US use glasses or contact lenses to correct their vision. And the World Health Organisation estimates that more than a billion people in low-and-middle income countries are living with sight problems that could be corrected by the right pair of specs. But how and when were glasses first invented? What impact have they had on societal development? And what are some of the ways we've stigmatised, or even elevated, people who wear them?

Joining Rajan Datar to explore the history of spectacles are Travis Elborough, a historian of popular culture from the UK. He’s recently published a book called Through The Looking Glasses: The Spectacular Life of Spectacles; Stefana Sabin, a German literary scholar and the author of In The Blink of an Eye – A Cultural History of Spectacles – which has just been translated into English; and Professor Kovin Naidoo, Senior Vice President in social impact at the French-based optics company, Essilor. He’s also former CEO of the Brien Holden Vision Institute. He originally trained as an optometrist in his native South Africa.

Sarah Bernhardt: Queen of stage and screen Oct 21, 2021

Whether photographed in a coffin or depicted on an Art Nouveau poster, the French actor Sarah Bernhardt knew exactly how to get maximum publicity. Although her first outings on the stage were unremarkable, she refined her skills and rose to become the leading actor of her generation and a world-famous name. Her life off-stage was a further source of endless fascination, her eccentric and occasionally arrogant behaviour only adding to her allure. Her critics saw her as manipulative and hackneyed. For her admirers, seeing Bernhardt ‘die’ on stage was a moment to be treasured for ever.

Bridget Kendall charts Sarah Bernhardt’s life and career with John Stokes, emeritus professor of modern British literature at King’s College London and author of The French Actress and Her English Audience; Victoria Duckett, senior lecturer in screen and design at Deakin University in Melbourne and the author of Seeing Sarah Bernhardt: Performance and Silent Film; and Sharon Marcus, the Orlando Harriman professor of English and comparative literature at Columbia University. Her 2019 book The Drama of Celebrity is an exploration of the processes that propel a figure such as Sarah Bernhardt to global fame.

A dirty history of diamonds Oct 14, 2021

We seem to have an almost insatiable appetite for the glitter and sparkle of diamonds. Yet transforming these stones into jewels fit for princesses and film stars involves a long chain of production and distribution. And the diamond industry has long been bound up with a much darker side: the exploitation of workers, environmental damage, all-powerful monopolies and violent mafias, not to mention the so-called Blood Diamonds used to finance armed conflict. So how is the industry trying to clean up its image and regulate the trade?

Joining Bridget Kendall to discuss the history of the diamond trade are:

Dr. Lansana Gberie, former coordinator for the UN Security Council Panel of Experts on Liberia. He is the author of A Dirty War in West Africa: The RUF and the Destruction of Sierra Leone. He’s also Sierra Leone’s current Permanent Representative to the UN in Geneva and the Sierra Leonean Ambassador to Switzerland - though his contributions to this programme are in a personal capacity.

Ian Smillie, founder of the Diamond Development Initiative, now DDI at Resolve, an organisation which works to improve conditions for small-scale miners. He is the author of several books, including Blood on the Stone: Greed, Corruption and War in the Global Diamond Trade. He is based in Canada.

Dr. Tijl Vanneste, researcher at the Portuguese Institute of International Relations at Nova University in Lisbon. He is the author of Blood, Sweat and Earth: The Struggle for Control over the World's Diamonds Throughout History.

The story of Evita Oct 07, 2021

Eva Peron rose from a childhood of poverty to become one of the most powerful figures in Latin America. An illegitimate small town girl, she smashed class and gender barriers to become Argentina’s controversial First Lady. Loved and loathed, Rajan Datar discusses her life, work and remarkable afterlife with biographer Jill Hedges, historian Ranaan Rein, and cultural theorist Claudia Soria.

Sushi: The Japanese dish with an ancient tradition Sep 30, 2021

It’s one of the most popular dishes in the world today, but the story of sushi can be traced back more than 2,000 years. The earliest records document a preserved fish dish in ancient China and it later became a medieval luxury in Japan, before evolving into a variety of different regional styles and recipes. Today, thanks to waves of migration from Japan, there is a veritable smorgasbord of international varieties… California roll, anyone?

Joining Rajan Datar to discuss the history of sushi are James Farrer, Professor of Sociology and Director of the Graduate Programme in Global Studies at Sophia University in Tokyo. He is the author of Globalisation and Asian Cuisines; Eric C. Rath is Professor of Premodern Japanese History at the University of Kansas in the US. He’s the author of Oishii: The History of Sushi; and Michelin-starred Japanese sushi master, Endo Kazutoshi, who is head chef at The Rotunda in London.

Toni Morrison: The legacy of a literary legend Sep 23, 2021

The American writer Toni Morrison once said, “If there’s a book that you want to read, but it hasn’t been written yet, then you must write it.” It was an urge which in her case yielded a rich array of novels, children’s books, plays and essays. Toni Morrison stands tall, as the first black woman of any nationality to be awarded the Nobel Prize for Literature. Celebrated for her masterpiece Beloved, she remains a towering figure, one of the most well-known and oft-taught authors of our age. Since her death in August 2019, many have been reassessing her multiple legacies: as a novelist, cultural critic, and editor.

Joining Bridget Kendall to explore the life, work and impact of Toni Morrison are Dana Williams, Professor of African American Literature at Howard University in Washington DC and current President of the Toni Morrison Society; Janis A. Mayes, Emerita professor of African American Studies at Syracuse University, US; and Aretha Phiri, Associate Professor at Rhodes University in Grahamstown / Makhanda, South Africa.

Algorithms: From the ancients to the internet Sep 16, 2021

Hidden from view, complex to understand and often controversial, algorithms are at the heart of computer coding that underpins modern society. Every time we search the internet, every time we pay by credit card, even the romantic partners suggested to us by online dating sites – they’re all powered by algorithms. And their reach is growing all the time, as some societies use them to automate decisions regarding criminal justice, mortgage applications and job recruitment.

The history of algorithms is surprisingly ancient, stretching back to the Babylonian empire where large societies required a systematic way to count and order different aspects of citizens’ lives. Today some people are questioning their use, as some algorithms have been shown to replicate bias and there are fears that algorithms have the potential to undermine democracy.

Bridget Kendall is joined by Ramesh Srinivasan, Professor in the Department of Information Studies at the University of California Los Angeles and the author of Beyond the Valley: How Innovators around the World are Overcoming Inequality and Creating the Technologies of Tomorrow; the French computational scientist, consultant and entrepreneur Aurélie Jean, who’s published From the Other Side of the Machine: A scientist’s journey in the land of algorithms; and Ian Stewart, Emeritus Professor of Mathematics at Warwick University who’s written more than 120 books on aspects of mathematics and science.

Louder! How the electric guitar conquered popular music Sep 09, 2021

Whether it be a kerrang, a chop, a blistering solo, some finger picking or a subtle flange, the electric guitar is one of the defining sounds of the 20th century. Without it – and its constant companion, the amplifier - popular culture would be unrecognisable today: no big gigs, no stadium concerts. And almost certainly no rock music. But why was it needed and how was it created? Who were the pioneers of the technology and who were the early-adopting exponents?

Rajan Datar and his three guest experts delve into the roots of this iconic instrument. Monica Smith is Head of Exhibitions and Interpretation for the Smithsonian's Lemelson Center for the Study of Invention and Innovation. Among the many projects she has curated at the museum is From Frying Pan to Flying V: The Rise of the Electric Guitar. Paul Atkinson is professor of Design and Design History at Sheffield Hallam university and the author of Amplified: A Design History of the Electric Guitar. HP Newquist is the founder of the National Guitar Museum in the United States. He has written numerous books on the guitar and its history, and was the editor-in-chief of Guitar Magazine.

Luigi Pirandello: Italian dramatist who brought chaos to the stage Sep 02, 2021

It’s a hundred years since the infamous premiere of Luigi Pirandello’s experimental play Six Characters in Search of an Author, when an enraged Rome theatre audience yelled abuse at the Italian playwright and chased him out of the theatre. Since then, the play has gained iconic status as a piece of theatre which helped move Western culture into modernity. But what of the author of this play? He was a complex figure who found inspiration from his wife’s madness as well as the actors he worked with, and he formed an unlikely association with the Italian Fascist Prime Minister Benito Mussolini which still intrigues theatre critics and academics to this day.

Joining Rajan Datar to discuss Luigi Pirandello and his work are Guido Bonsaver, Professor in Italian Cultural history at the University of Oxford; Dr Enza de Francisci, lecturer in Translation studies at the University of Glasgow, who specialises in Pirandello’s Sicilian identity and his portrayal of women, and is the author of A 'New' Woman in Verga and Pirandello: From Page to Stage; and Patricia Gaborik, who teaches theatre history at the University of Calabria in Italy, and has studied Pirandello’s relationship with the Italian Fascist leader Mussolini and is the author of Mussolini’s Theatre: Fascist Experiments in Art and Politics.

The readings were by Marco Gambino.

Produced by Anne Khazam for the BBC World Service.

Mars: A history of the Red Planet Aug 26, 2021

With three separate missions exploring the Red Planet in 2021, Mars is once again under the spotlight. But to tell the truth, it’s never been away. Mars has fascinated people for centuries with its seemingly curious motion in the night sky, its red colour and the eternal question as to whether it may or may not harbour life, past or present.

Since the 1960s, robotic exploration of Mars has provided us with evidence that it may have had periods where it was once a warm and wet planet. That’s in contrast to the arid, cold celestial object we know today. The harsh Martian atmosphere presents challenges for anyone hoping to land humans on the planet. But nevertheless, the next few decades could potentially see either a private commercial operator, a national space agency or an international partnership make history with the planet’s first human exploration. Some have even argued that’s a first step to ‘terraforming’ or populating Mars in the future.

Bridget Kendall is joined by Michael Meyer, the lead scientist for NASA’s Mars Exploration Programme; Sarah Stewart Johnson, Associate Professor of Planetary Science at Georgetown University and author of The Sirens of Mars; Jorge Vago, the Scientist for Mars Missions at the European Space Agency, and curator Matthew Shindell from the Smithsonian National Air and Space Museum in Washington, DC.

A radiant light: The Indonesian poet Amir Hamzah Aug 19, 2021

The writer Amir Hamza is a national hero in Indonesia celebrated for both his poetry and his role in the development of the country’s national language. Hamza was an emotional man who struggled with thwarted love and inner conflict and created a beguilingly intense body of work. His poetry paid homage to Malay literary tradition infused with Islamic mysticism but also reflected new ideas springing up in the artistic circles in Java where he worked in the 1930s. Towards the end of that decade events conspired to enforce his return to the family home in Sumatra and ultimately led to his becoming a tragic victim of brutal retribution during Indonesia’s transition to independence.

Rajan Datar is joined by Ayu Utami, an award-winning Indonesian novelist, playwright and broadcaster; Ben Murtagh, Reader in Indonesian and Malay at SOAS, University of London, and managing editor of the journal Indonesia and the Malay World; and Taufiq Hanafi, an Indonesian literary scholar currently at the Royal Netherlands Institute of Southeast Asian and Caribbean Studies in Leiden. The reader is Sallehuddin Abdullah-Sani.

Sailing by the stars: The pioneering voyages of David Lewis Aug 12, 2021

David Lewis was of one of the most remarkable nautical explorers of modern times. In the mid-1960s, he took his wife and two small daughters - who were less than five years old - on a sailing trip around the world in a small catamaran. What is more, for one part of the journey, he rejected standard 20th-Century navigational equipment and relied on much older methods of finding his way across the Pacific. In fact, it was his lifelong goal to prove that ancient seafaring methods were still valuable and his research helped revive ancient Polynesian navigation methods. In his more than eventful life, he also wrote a dozen books, practised as a GP in London’s East End and tackled many unclimbed peaks as a mountaineer. And he undertook hazardous trips to the Antarctic including one in which he was presumed dead.

Rajan Datar is joined by David’s son Barry, who is also an accomplished sailor and who accompanied David on some of his seminal voyages; Dr. Christina Thompson, the editor of Harvard Review and the author of Sea People: The Puzzle of Polynesia; and Ben Lowings, a yachtsman, BBC journalist and the author of David Lewis's biography entitled The Dolphin.

Inside the mind of crime writer Patricia Highsmith Aug 05, 2021

Patricia Highsmith was one of the most successful suspense writers of the 20th century. Known especially for her novels The Talented Mr. Ripley, Carol and Strangers on a Train, she created complex and alluring characters, capable of terrible things and at the same time deeply human. Yet for much of her life, Highsmith herself remained an enigmatic figure, often seen as eccentric, troubled and difficult. But she had a circle of close friends who were loyal to the end.

Presenter Bridget Kendall is joined by Andrew Wilson, author of the first biography of Highsmith, and Vivien De Bernardi, a close friend of Highsmith's during her later years in Switzerland.

Ibn Sina: The Persian polymath Aug 02, 2021

Over a thousand years ago in the city of Bukhara in modern-day Uzbekistan, a young man was gaining a reputation for his great medical knowledge. His name was Ibn Sina and he was to go on to become one of the most influential physicians and philosophers not just in the Islamic world, but also in the West, where his writings were translated into Latin under the name Avicenna. For over 500 years, his five-volume Canon of Medicine was the most important medical reference book in the world.

Joining Bridget Kendall to discuss Ibn Sina are: Nader El-Bizri, Professor of Philosophy and Civilisation Studies at the American University in Beirut; Peter E. Pormann, Professor of Classics and Graeco-Arabic Studies at the University of Manchester; and Emann Allebban, Assistant Professor in Philosophy at Providence College in Rhode Island in the US.

The Panama Canal: The real story behind the engineering triumph Jul 29, 2021

Completed in 1914, the Panama Canal has long been regarded as a triumph of American ingenuity, a conquest over nature that helped secure the United States’ position as a world power. Taking ten years to build, it opened up new trading routes between East and West by providing a vital waterway between the Atlantic and Pacific oceans. But what was the real story behind this challenging engineering project? How were the Panamanians affected? Who were the tens of thousands of workers who built the canal? And what was the environmental impact of work that literally cut through a mountain and redirected two oceans? And with climate change, will the Panama Canal be such a vital waterway in the future?

Joining Bridget Kendall, is the Panamanian academic Dr Marixa Lasso, author of “Erased: The Untold Story of the Panama Canal”, the first major book on the Canal from the Panamanian point of view; Julie Greene, Professor of History at the University of Maryland, and the author of “The Canal Builders: Making America’s Empire at the Panama Canal”, and Paul Sutter, Professor of Environmental History at the University of Colorado, Boulder, and author of a forthcoming book on the impact of US public health measures during the construction of the Panama Canal.

Ida Pfeiffer: 19th Century globetrotter Jul 22, 2021

Ida Pfeiffer's desire to see the world was like many childhood fantasies - destined to remain just that. And yet at the age of 44 once her sons had reached adulthood, she set off from her home in Vienna on a series of journeys that no woman of her time or background had contemplated.

Beginning with a trip to the Middle East, Pfeiffer travelled mostly alone, documenting her voyages and collecting specimens that she later sold to help finance her adventures abroad. Budget travel was her mantra, as she was not a wealthy aristocrat like many travellers of that time. On her journeys Pfeiffer was attacked, kidnapped, robbed and almost drowned. She met head-hunters and endured extreme conditions to pursue her dream. Defying all convention, Pfeiffer became celebrated as the most travelled woman on the planet, circumnavigating the globe twice. But despite her trailblazing attitude, she was no feminist, believing that women should be either professionals or home-builders, not both.

Rajan Datar discusses the life of this most unlikely traveller with the social and cultural anthropologist Hiltgund Jehle; Ulrike Brisson, whose research has focused on 19th and early 20th-Century European women's travel writing; and John van Wyhe, senior lecturer in the department of biological sciences at Tembusu College in Singapore, and author of Wanderlust: The Amazing Ida Pfeiffer, the first female tourist.

Rain or shine? A short history of the weather forecast Jul 15, 2021

How did we get from not having any reliable way of predicting the weather just 150 years ago, to today's accurate, tailor-made forecasts for places as small as a village? Bridget Kendall and guests trace the history of meteorology, from its first steps as an aid to quicker trans-Atlantic shipping to the latest methods which can help anticipate weather events as short-lived as a tornado.

Bridget is joined by Kristine Harper, a former US Navy forecaster and now a history professor at Florida State University; Peter Gibbs who started out as a meteorologist with the British Antarctic Survey and the UK's Met Office before becoming one of the best known weather forecasters on BBC radio and television; and Peter Moore, a writer and historian with a particular interest in weather discoveries of the 19th century.

Emile Berliner, inventor of the gramophone Jul 08, 2021

A young immigrant to the USA who started out working in a draper's shop, Emile Berliner ended up paving the way for the world of recordings and home entertainment that we delight in today. But even before he got to work on his recording machine - which he would later call the gramophone - Berliner made a major contribution to another piece of technology that's very familiar to us today: the telephone. And not content with all these achievements, he also promoted the pasteurisation of milk, financed a major scholarship for women to pursue academic research and tried to develop a working helicopter. So how did Berliner come up with these ideas? Why was he at one point prevented from selling his gramophones and records? And why is his name less well known today than those of his contemporaries Nikola Tesla, Thomas Edison and Alexander Graham Bell?

Bridget Kendall is joined by three Berliner experts: Dr. Anja Borck, director of the Musee des ondes Emile Berliner in Montreal; Sam Brylawski, former head of recorded sound at the Library of Congress in Washington which houses an extensive Berliner archive; and David Giovannoni, a historian of recorded sound and the co-author of E. Berliner's Gramophone - a study of the American disc industry from 1892 to 1900.

Tracing the roots of ancient trees Jul 01, 2021

Have you ever sat against the trunk of a large old tree, looked up into its canopy and wondered what it’s seen in its lifetime? There are many species of tree that survive well beyond a human lifespan, for hundreds of years, and some that can live far longer than that, spanning millennia. What can we learn from large old trees around the world? How do they influence the environment? And how can we preserve them for future generations?

Joining Bridget Kendall to discuss ancient trees are Peter Crane, former director of the Royal Botanic Gardens at Kew in London; Valerie Trouet, Professor at the Laboratory of Tree-Ring Research at the University of Arizona in the US; and conservation biologist, Michael Gaige.

The Wizard of Oz: A homegrown American fairy tale Jun 24, 2021

The Wizard of Oz is best known as one of the most watched films of all time, or as one of its many re-incarnations, such as the hugely successful Broadway musical Wicked or the Soviet, The Wizard of the Emerald City. But fewer people nowadays may be aware of the original book by the American writer L. Frank Baum that inspired these stories about a young girl who travels through a magic land in the company of a talking scarecrow, a tin man and a fearful lion. While he was a controversial figure, it was L. Frank Baum’s ideas about social justice and rights for women which pervade not just The Wizard of Oz but also its sequels, and explain why this story in its many forms has inspired many minority groups, from the African American to the LGBT communities.

Joining Bridget Kendall is Michael Patrick Hearn, considered to be the world’s leading Oz scholar, and author of The Annotated Wizard of Oz; Dr Sally Roesch Wagner, who specialises in the feminist aspects of The Wizard of Oz including the influence of Frank Baum’s mother-in-law, the women’s rights campaigner, Matilda Joslyn Gage, and the Russian writer Olga Zilberbourg who has studied the very popular Soviet version of the story.

Falconry: The history of hunting with birds of prey Jun 17, 2021

The practice of hunting with birds of prey is thought to stretch back thousands of years. In early nomadic societies, falconry was used to hunt animals to provide food and clothing in places such as the steppes of Central Asia. As the practice spread, falconry evolved into a pastime that attracted the elite of European society, reflected in the extensive iconography of noblemen and women and their falcons. Today falconry is found in more than 90 countries around the world.

At its core remains the importance of the relationship between falconer and the bird of prey, a bond unlike any other between man and beast.

But although falconry has been classed as intangible cultural heritage by UNESCO, there are challenges to its survival. And some argue that falconry itself is exploitative.

Rajan Datar is joined by the president of the International Association for Falconry, His Excellency Majid al-Mansouri; Adrian Lombard, Chair of the South African Falconry Association; art historian Anne-Lise Tropato, the first Falconry Research Fellow at New York University Abu Dhabi, and social anthropologist Sara Asu Schroer who's researched the relationships between falconers and birds of prey through fieldwork in Britain and Europe.

Aramaic: An imperial language without an empire Jun 10, 2021

Aramaic is a language that for some three thousand years facilitated the exchange of ideas across large tracts of the Middle East and Asia. In its heyday it was the main official and written language across the Neo-Assyrian and Achaemenid empires. It was the language in which several sections of the Old Testament Bible were written. A Galilean dialect of Aramaic was probably the language Jesus spoke. Different dialects of Aramaic still exist today but numbers of speakers are dwindling and there are fears that it could die out.

So what is the story of Aramaic? Why did it become so influential and then go into decline? And how much has it changed over its long history?

Bridget Kendall is joined by three distinguished scholars of Aramaic: Professor Holger Gzella from Ludwig-Maximilians University in Munich is the author of numerous publications on Aramaic as well as being an expert on other Old Testament languages.

Professor Alison Salvesen from Oxford University works on ancient interpretations of the Hebrew Bible including its Aramaic versions. She is also an authority on Jacob of Edessa, a leading religious scholar who wrote in one of the many variants of Aramaic.

Dr. Alinda Damsma teaches Biblical Hebrew at University College London and Aramaic at the Ecole Rabbinique in Paris. She studies medieval Aramaic dialects, especially in Jewish mystical literature, and has also done field research on the current use of the language.

X-rays: New ways of seeing Jun 03, 2021

The discovery of X-rays by the German scientist Wilhelm Roentgen in 1895 was nothing short of ground-breaking, opening up a new era in medicine. For the first time, doctors could see inside the human body without the need for surgery, and diagnose many more living patients.

X-rays had major implications for physics as well, allowing scientists to study the structure and arrangement of molecules. Within wider society, they inspired artists to explore what these new rays could tell us about the representation of reality. It wasn’t long before X-rays were being used to scan baggage, in airport security and even in shoe shops to measure feet before exposure to radiation was properly understood. Huge strides in X-ray technology have given us the type of modern scans that are used today to detect conditions such as cancer.

Joining Bridget Kendall are Drs Adrian Thomas and Arpan Banerjee, both radiologists who’ve collaborated on publications about the history of X-rays, and artist Susan Aldworth who’s used brain scans in her work to investigate the nature of identity.

Machiavelli, master of power May 27, 2021

Over five hundred years ago, dismissed diplomat Niccolò Machiavelli produced his most famous work, The Prince. Written on the fringes of the Italian city of Florence, the book has long been read as a priceless guide to power and what holding it truly involves. But who was the man behind the work? Why did he claim that a leader must be prepared to act immorally? And why did the name of this one-time political insider become a byword for cunning and sinister strategy?

Rajan Datar explores the life and impact of Machiavelli’s The Prince with writer and scholar Erica Benner, historian professor Quentin Skinner, and journalist and novelist David Ignatius.

The birth of the modern car May 20, 2021

The motor car is a feature of contemporary life the world over but when and where did motor vehicles begin? How did we get from the slow, noisy, dangerous, early vehicles of the 19th century to the swish, sleek, practical cars of today? Why did the early electric vehicle – so popular early on and the first car to go faster than a hundred kilometres an hour - suddenly fall out of favour? And who were the early engineers whose major contributions to car design deserve to be better known? These are some of the questions that Bridget Kendall asks three automotive experts: writer and broadcaster Giles Chapman is the award-winning author of 55 books on car history, culture and design; Larry Edsall also has many automotive books to his name; he has written about cars for many American newspapers and is founding editor at ClassicCars.com; and Gundula Tutt is a leading German restorer of historic vehicles whose work graces many public and private museums. She has a particular interest in the science and technology of car paint and other finishes and is the founding member of the Institute for Automobile Forensics.

Ukulele - a history of Hawaii's national instrument May 13, 2021

Throughout its 130-year-old history, the ukulele has often been underrated – for many, this tiny four stringed instrument is a musical joke, a plastic toy or a cheap airport souvenir, but in fact, some of the world’s greatest musicians have played and admired it, and it has enduring associations with the struggle for Hawaiian independence since its arrival on the islands from Madeira in the late 19th century. The ukulele is also surprisingly versatile and musicians are forever involved in the challenge of expanding its repertoire, from Bach to ukulele concertos to jazz.

Joining Bridget Kendall to find out more about this deceptively humble instrument is the award-winning musician Brittni Paiva, who’s been described as Hawaii’s pre-eminent ukulele artist; Jim Beloff, the co-founder of Flea Market Music, publishers of some of the first ukulele song books which played a key part in the modern ukulele revival, his forthcoming memoir is UKEtopia: Adventures in the Ukulele World; and Samantha Muir, a classical ukulele musician and composer, who’s doing a PHD at the University of Surrey in the UK to create new works for the classical ukulele repertoire.

Tadeusz Kosciuszko, groundbreaking fort builder May 06, 2021

The American president Thomas Jefferson called Tadeusz Kosciuszko "as pure a son of liberty as I have ever known". Kosciuszko was born in what is today Belarus, trained as an engineer in Poland and France and went on to become one of the important military players in the American War of Independence. This was when he wasn’t pursuing his dream of a free Polish republic against the might of a conservative aristocracy and neighbouring Russian and Prussian armies. Or campaigning against slavery and feudalism. Testimonials like that of Jefferson’s lauding his humility, energy and high moral principles flowed from around the world. He was toasted as a celebrity in London by the likes of Keats and Coleridge. In the USA and Europe there are bridges, statues and monuments in his name. And yet today Kosciuszko is relatively unknown outside of Poland.

Rajan Datar aims to change that with the aid of three Kosciuszko experts: Dr. Betsey Blakeslee, President of the Friends of the American Revolution at West Point, an organisation that works to preserve the fortifications Kosciuszko designed and built at West Point. She earned her PhD in American Studies at the University of Maryland; Kamil Ruszala, Assistant Professor of History at Jagiellonian University in Kraków whose research focuses on the modern history of Central Europe; and writer and Pulitzer-prize-winning journalist Alex Storozynski, Chairman of the Board of the Kosciuszko Foundation and author of Kosciuszko's biographies both in a book and film form.

The census: A snapshot of life Apr 29, 2021

Anyone who has ever researched their family tree will have most likely come across the census, the process by which every citizen or subject of a country is counted and classified. Data collected by the census, often carried out every ten years, has been invaluable to genealogists, both amateur and professional. And the census has also developed into an essential tool for governments and organisations to plan how and where they focus their investment in public services such as health care and schools.

Inventories of people are known to stretch back to antiquity in places such as Egypt and China, and asked for very basic information for the purposes of tax collection or military service. The modern-day census, however, focuses on questions that touch far more on an individual’s identity and has often been controversial. Now that modern technology makes population data easily accessible in a variety of forms, some are questioning whether there is a need for censuses at all.

Bridget Kendall is joined by Dr Kathrin Levitan, Associate Professor at William & Mary in Williamsburg, Virginia and the author of A Cultural History of the British Census: Envisioning the Multitude in the Nineteenth Century; sociologist Dr Tukufu Zuberi, the Lasry Family Professor of Race Relations at the University of Pennsylvania and head of the African Census Analysis Project; and data scientist and economist Andrew Whitby, author of The Sum of the People: How the Census Has Shaped Nations from the Ancient World to the Modern Age.

Unravelling the history of knitting Apr 22, 2021

Like many traditional domestic crafts, knitting has experienced a huge surge in popularity in the 21st century, making it fashionable and even radical. But the history of hand knitting is still relatively obscure. The oldest knitted artefacts are Coptic socks found in Egypt dating from the fourth century AD, but although they look like modern-day knitting, they’re actually made using a technique called nalebinding or needle-binding.

So what then are the real origins of knitting? How did it develop into so many different regional patterns, from the famous Fair Isle of Scotland to distinctive Nordic and South American variations?

Joining Bridget Kendall to discuss the global history of knitting are Professor Sandy Black of the University of the Arts London, Norwegian textile designer, Annemor Sundbo, and an expert on South American knitting, Cynthia LeCount Samaké.

One Hundred Years of Solitude: The story of Latin America Apr 15, 2021

Considered to be one of literature’s supreme achievements, One Hundred Years of Solitude by the Colombian novelist Gabriel García Márquez is reported to be the most popular work of Spanish-language fiction since Don Quixote in the 17th century. Written in 1967, it tells the story of seven generations of the Buendía family, whose patriarch is the founder of a fictional Colombian village called Macondo. But why is it said this novel – which fuses the fantastical and the real – tells the story of Latin America and has given an entire continent its voice?

Joining Bridget Kendall are Ilan Stavans, Professor in Latin American and Latino Culture at Amherst College in Massachusetts, in the United States, and the biographer of Gabriel García Márquez; María del Pilar Blanco, Associate Professor in Spanish American literature at Oxford University, and Parvati Nair, Professor of Hispanic, Cultural and Migration studies at Queen Mary, University of London.

Rabindranath Tagore: The Bard of Bengal Apr 08, 2021

So prodigious was the polymath Rabindranath Tagore, there’s a saying in Bengal that one lifetime is not enough to consume all of his work. Poet, playwright, thinker, activist, educator, social reformer, composer, artist… the list of his talents is long. Today his name is known all over India and Bangladesh; children recite his poetry at school and his legacy lives on in many different ways.

When he became the first non-European to win the Nobel Prize for Literature in 1913, Tagore was feted for a time by American and European literary figures who saw in him someone who embodied Western preconceptions of a mystic Oriental sage. As a result of his newfound fame outside India, Tagore travelled widely and exchanged ideas with many celebrated world leaders and thinkers from Einstein to Gandhi. Today Tagore’s thoughts on education and his stance vis-à-vis the natural world and our relationship to the environment are seen as remarkably forward-looking.

Rajan Datar is joined by Kathleen O’Connell, retired lecturer in South Asian Studies from the University of Toronto and the author of Rabindranath Tagore: the Poet as Educator; the writer Aseem Shrivastava who lectures on Tagore and his ecological thought at Ashoka University in Delhi; and Chandrika Kaul, Reader in Modern History at the University of St Andrews, who’s published widely on imperial and modern India.

Pauline Viardot: 19th-Century diva Apr 01, 2021

While the name of Pauline Viardot may be unfamiliar to many, in her lifetime she was one of the most celebrated performers in Europe. Her interpretation of Orpheus in a revival of Gluck’s opera made the writer Charles Dickens weep, and the novelist George Sand said that whenever she heard Pauline Viardot sing, nothing else mattered. In addition to her vocal talents, Pauline Viardot dazzled in high society. She knew almost everybody who came to define 19th Century European culture, thanks to the regular salon she held with her husband in their Parisian townhouse. Acclaimed poets, musicians, composers, artists and even royalty would come to take tea, listen to music, network, perform and share ideas.

Alas there are no recordings of her magnificent voice, even though her later years coincided with the beginning of the recording industry. But today Pauline Viardot’s legacy is being rediscovered as a composer, with works that were performed at her salons reaching new audiences.

Bridget Kendall is joined by Hilary Poriss, associate professor of music history at Northeastern University in Boston who is writing a monograph on Pauline Viardot to be published by the University of Chicago Press; Patrick Barbier, emeritus professor at the West Catholic University in Angers, and author of a biography of Pauline Viardot and her sister; and Richard Langham Smith, who has published widely on 19th and early 20th Century French music and is currently research professor at the Royal College of Music in London.

The One Thousand and One Nights Mar 25, 2021

The One Thousand and One Nights are a collection of fantastical stories of flying carpets, magic and genies whose ancient origins go back to the 7th century or earlier. The tales are told by Scheherazade who uses the power of storytelling night after night to stop her Sultan husband from beheading her.

These highly influential stories were brought to the West in the 18th century, when more tales like Aladdin and Ali Baba were said to have been added by the French translator, and it has continued to evolve over the centuries. Rajan Datar and guests explore why these stories became so popular around the world and what they mean to us today.

Joining Rajan is Wen Chin Ouyang, Professor of Arabic at SOAS in London; Dr Sandra Naddaff, senior lecturer in Comparative Literature at Harvard University; and the Iranian TV producer Shabnam Rezaei.

Adventures with dentures: The story of dentistry Mar 18, 2021

Until the eighteenth century there were no professional dentists. The only way to deal with a serious case of toothache was to call on the services of blacksmiths, travelling showmen or so-called barber-surgeons, all of whom had a sideline in tooth extraction. But in 1728, French physician Pierre Fauchard published the first complete scientific description of dentistry and he is credited as being “the father of modern dentistry”. His book, Le Chirurgien Dentiste or The Surgeon Dentist, was translated into several languages.

Joining Rajan Datar to discuss the painful and sometimes gruesome history of humans and their teeth are Dr. Scott Swank of the National Museum of Dentistry in Baltimore, US; Rachel Bairsto, Head of Museum Services at the British Dental Association and Professor Dominik Gross of RWTH Aachen University in Germany.

BR Ambedkar: The Dalit hero of India Mar 11, 2021

Educate, Agitate, Organise. This was the motto of the Indian scholar BR Ambedkar who led an extraordinary life of activism and achievement. It put him in conflict with many other political forces in his native country, such as the Indian National Congress and Mahatma Gandhi. In India itself, Ambedkar's legacy is widely respected but in other countries he is not so well known. And yet, Ambedkar was not only a leading intellectual of his day, brilliant orator, lawyer, successful politician and an unmatched champion of those suffering the harshest discrimination: he was also someone who rose from a Dalit background to being put in charge of writing the first constitution of independent India. The Dalits are the lowest of the low in the Indian social hierarchy, often considered as being below the lowest caste.

To tell Ambedkar's story Rajan Datar is joined by three distinguished Ambedkar scholars: Sunil Khilnani, professor of politics and history at Ashoka University and author of Incarnations: India in Fifty Lives; Valerian Rodrigues, emeritus professor of political studies at Jawaharlal Nehru University and first Ambedkar chair at Ambedkar University, both in New Delhi, and author of The Essential Writings of B.R. Ambedkar; and Ananya Vajpeyi, associate professor at the Centre for the Study of Developing Societies in New Delhi and author of Righteous Republic: The Political Foundations of Modern India.

Making waves: the history of swimming Mar 04, 2021

Common to many cultures across the world, swimming appears on the surface to be a benign leisure activity. But in fact it has much to tell us about such things as the development of societies, our bodies and minds, and our relationship to our ancestors and the natural world.

For the Ancient Greeks and Romans, swimming was essential for instilling discipline, as a necessary skill for warriors, and to promote wellbeing. In West Africa where water had spiritual significance, communities there placed great importance on learning to swim from an early age. Their aquatic skills surprised the early colonialists, who then targeted divers to help them plunder shipwrecks when they were trafficked to the New World. Today however African American children are almost six times more likely to drown than their white counterparts as a consequence of historic racial segregation, according to research by the US Centers for Disease Control.

Rajan Datar is joined Professor Kevin Dawson from the University of California Merced, author of Undercurrents of Power: Aquatic Cultures in the African Diaspora; Mikael Rosén, swimmer, coach and author of Open Water: The History and Technique of Swimming; journalist Howard Means, author of Splash!: Ten Thousand Years of Swimming and writer Bonnie Tsui whose book Why we Swim was published in 2020.

Abraham Maslow’s psychology of human needs Feb 25, 2021

Many students of psychology, business, nursing and other disciplines are taught about "Maslow's pyramid of human needs", a diagram that shows a progression from our basic needs, such as food and shelter, to higher, social needs and, eventually, to striving for often intangible life goals and fulfilment. The pyramid is an iconic image, yet Abraham Maslow, a leading humanistic psychologist of the 20th century, didn't actually create it. Moreover, his writings are much more sophisticated and perceptive than the diagram suggests. So where did this confusion come from and why didn't Maslow disown the pyramid? How should we understand Maslow's hierarchy of human needs? Why has it proved so useful in so many different disciplines? And in what way is it relevant to how we live today?

These are some of the questions that Bridget Kendall explores with Jessica Grogan from University of Texas at Austin, author of Encountering America, a history of humanistic psychology; David Baker, emeritus professor of psychology and former director of the Cummings Center for the History of Psychology at the University of Akron; and Scott Barry Kaufman, former director of the Imagination Institute at the University of Pennsylvania and author of Transcend which updates Maslow for the 21st century.

The Kalevala: the Finnish epic that inspired a nation Feb 18, 2021

When the Kalevala was published in 1835, Finland had a distinct cultural and linguistic identity but it had always been part of either the Swedish or the Russian empire. Neither did Finland have much of a literary tradition, but as the 19th-century progressed the Kalevala took on a symbolic role as the representation of a Finnish identity that fed into the movement for Finnish independence. Rooted in the folk culture of the Karelia region, a travelling doctor shaped the song texts into a story in a way which is still being debated today.

Joining Bridget Kendall to discuss how the Kalevala underscored the search for Finnish national identity are Dr Niina Hämäläinen, executive director of the Kalevala Society in Helsinki; Professor Tom DuBois from the University of Wisconsin-Madison, the author of Finnish Folk Poetry and the Kalevala; and the award-winning British musician, playwright and storyteller, Nick Hennessey.

Sister Juana, a great mind of Mexico Feb 11, 2021

Sister Juana Ines de la Cruz is celebrated today as one of the finest poets in the history of Mexico. She was not just a creative and intellectual force but also a campaigner for women’s education and someone not afraid to challenge male hypocrisy. The colonial 17th-century society in which she lived was very patriarchal so, not surprisingly, her views brought her into conflict with the men in power.

Rajan Datar looks at key episodes in Sister Juana’s life and examines the passion and ingenuity in her poetry and plays with the help of Alicia Gaspar de Alba, Professor at University of California Los Angeles and a writer whose novels include Sor Juana’s Second Dream; Dr. Amy Fuller, Senior Lecturer at Nottingham Trent University, specialist in early modern Spain and Mexico and author of Between Two Worlds, a monograph on Sister Juana's plays; and Rosa Perelmuter, Professor of Romance Studies at University of North Carolina at Chapel Hill. The reader is Pepa Duarte.

Mermaids: Tales from the deep Feb 04, 2021

We delve into the watery depths of sea creature folklore, with a round-the-world tour of different variations on the concept of mermaids – from the Sirens of Greek mythology to the Selkies or Seal Folk of Scottish legend, and water spirits known as Mami Water, which are venerated in parts of Africa and the Americas. Not forgetting the famous fairy tale, The Little Mermaid, which has captivated the imagination ever since its publication in 1837 and was popularised by Disney in the 1980s.

Joining Bridget Kendall to discuss what these ancient stories can tell us are Cristina Bacchilega of the University of Hawaii, co-editor of The Penguin Book of Mermaids; British writer, Marcelle Mateki Akita, who has written a book for children called Fatama and Mami Wata's Secret; and Lynn Barbour, founder and Arts Director of the Orkney Folklore and Storytelling Centre in the Orkney Islands in Scotland.

Eleusinian Mysteries: Secret ceremonies promising happiness Jan 28, 2021

In ancient Greece, thousands of people flocked each year to join the religious rites known as the Eleusinian Mysteries. Based on the cult of the goddess of fertility Demeter and her daughter Persephone, the Mysteries were for many a profoundly moving and life-changing experience. People from all over the Greek world and beyond travelled to Eleusis for at least 800 years and the ceremonies remained a highlight of the Athenian calendar throughout that time. But what really went on in the great hall of the sanctuary at Eleusis? Why did the organisers deem it necessary to issue a strict injunction against divulging what actually took place - and what happened to some of those who broke that rule?

These are some of the questions Bridget Kendall discusses with Christy Constantakopoulou, professor in ancient history and classics at Birkbeck College, London; Esther Eidinow, professor of ancient history at Bristol University; Dr. Philippe Michel Matthey who lectures about ancient religions at Geneva University; and Dr. Julietta Steinhauer, a lecturer in Hellenistic history at University College, London.

Toussaint L’Ouverture: Hero of the Haitian slave rebellion Jan 21, 2021

Late 18th-Century Saint Domingue in the Caribbean – now known as Haiti – was one of the richest countries in the world. Known as ‘the pearl of the Antilles’, its wealth was built almost entirely on slavery. Around half a million enslaved Africans were transported to the French colony to work on the sugar plantations.

Toussaint L’Ouverture was destined to see out his days within this brutal system, but his skills as a negotiator and communicator saw him rise to the forefront of the resistance movement on the island. A wily and charismatic operator, he galvanised his fellow countrymen and women to lead history’s first and only successful slave uprising.

Diverging from French colonial rule brought him to the attention of Napoleon Bonaparte, who sent a large fleet to re-establish slavery on Saint Domingue. The expedition ended with Toussaint’s capture and exile to France, where he died in a cold prison cell in 1803. But his generals meanwhile carried on the struggle to uphold Toussaint’s opposition to slavery, which became the basis for the new independent state of Haiti.

Joining Rajan Datar to explore this complex figure are Marlene L Daut, Professor of African Diaspora Studies in the Carter G. Woodson Institute at the University of Virginia, and the author of Tropics of Haiti: Race and the Literary History of the Haitian Revolution in the Atlantic World, 1789-1865; Weibert Arthus, the Haitian ambassador to Canada, who’s also published widely on Haitian diplomacy and history; and Sudhir Hazareesingh, professor in politics at Balliol College, Oxford. His biography Black Spartacus: The epic life of Toussaint Louverture was published in 2020.

Olympe de Gouges: France’s forgotten revolutionary heroine Jan 14, 2021

She fought to give women the right to divorce and campaigned on behalf of children born out of wedlock. But in late 18th century France, her radical thinking proved too much for her contemporaries in the French revolution. She insisted women should be allowed to speak out, and she was executed at the guillotine for doing just that. For nearly two centuries her story was largely forgotten, until she was championed by modern-day French feminists, who called for her to be given pride of place in the pantheon of France’s national heroes.

Joining Bridget Kendall to discuss the life of the French political activist and playwright Olympe de Gouges are: French philosopher of feminist thought, Geneviève Fraisse; Professor Catriona Seth of the University of Oxford; and British-French playwright and translator, Clarissa Palmer.

Alexandre Yersin and the race to fight the plague Jan 07, 2021

When Alexandre Yersin discovered one of the most lethal bacteria in human history, the tiny bacillus of the plague that over the centuries had killed tens of millions of people, he earned his place in the history books. Working in a straw hut in Hong Kong, armed with just a microscope, Yersin’s methodical mind worked out within just a few days where in human body to look for the plague bacteria. A much bigger and better-equipped Japanese team, competing with Yersin, came away empty-handed. So who was Alexandre Yersin? Why did this pioneering Swiss scientist spend most of his life in Vietnam? And why did it take decades fully to credit Yersin with the discovery of the microorganism that now bears his name, Yersinia pestis?

These are some of the questions Bridget Kendall discusses with film director Stephane Kleeb, who made a documentary about Yersin; Professor Maxime Schwartz, medical historian and former director of the Pasteur Institute in France; and Dr. Mary Augusta Brazelton from Cambridge University whose research focuses on medical history of Asia.

Famous hats in history Dec 31, 2020

There have been so many, probably hundreds, different styles and types of hat in history that a question inevitably arises: why? Why did something that began as a simple protection against inclement weather take on such varied forms and social meanings? Bridget Kendall and guests explore not just how hats were made, and by whom, but also how their function has evolved over centuries and across cultures. By focusing on just five distinct hat types, they sketch out a brief social history of headwear.

Bridget is joined by Dr. Drake Stutesman, an adjunct professor at New York University, and the author of the book Hat: Origins, Language, Style; Dr. Ulinka Rublack, professor of Early Modern European History at Cambridge University with a particular interest in Renaissance fashion; and Dr. Kirill Babaev, a cultural anthropologist and writer from the Russian Academy of Sciences and founder of the World of Hat museum in Riga, Latvia.

Mugham: the sound of Azerbaijan Dec 24, 2020

Azerbaijan’s strategic location along the old Silk Road and its wealth of natural resources has made it a prime target for warring empires over centuries. The conquests and the invasions by Turkic and Persian peoples find echoes in the traditional art music of Azerbaijan known as mugham. The influence of the Russian and then Soviet empire also brought change for mugham, the effects of which are still debated today.

Mugham is characterised by a large degree of improvisation, but musicians learn for years from mugham masters to acquire the skills which allow them to extemporise within a strict framework. It’s no surprise to learn that in the 20th century, mugham fused with that other great improvisatory music – jazz. With the help of musical examples, Rajan Datar and guests will explore how mugham works and the instruments such as the tar and the kamancha that give this music its unique sound.

Joining Rajan will be ethnomusicologist and tar player Dr Polina Dessiatnitchenko who’s writing a book on mugham in post-Soviet Azerbaijan; Jeffrey Werbock, musician and chair of the Mugham Society of America; and music producer and artistic patron Nasib Piriyev, who set up BUTA Arts, an organisation designed to raise awareness of Azeri music and culture.

The Kingdom of Aksum: Africa's trading empire Dec 17, 2020

At its height, the Aksumite Empire extended across the northern Ethiopian and Eritrean highlands, and even included parts of Sudan, Somalia and modern-day Yemen. From the first century BC to the seventh or eighth centuries AD it was one of the most important trading hubs in north-east Africa. It was also one of the earliest states in the world to adopt Christianity. In fact the Persian prophet Mani named the Aksumite Empire as one of the “four great kingdoms on Earth” together with Persia, Rome and China. But despite its power and reputation, we’re only now beginning to understand more about the lives of the people who lived there.

Joining Bridget Kendall to discuss the Aksumite Empire and its legacy are Helina Solomon Woldekiros, Assistant Professor of Archaeology at Washington University in St Louis, Missouri; Felege-Selam Solomon Yirga, Assistant Professor of History at the University of Tennessee; and Dr. Niall Finneran, Reader in Historical Archaeology and Heritage Studies at the University of Winchester in the UK. He is author of The Archaeology of Ethiopia.

Umm Kulthum: Egypt’s singing superstar Dec 10, 2020

Umm Kulthum’s powerful voice and talent for communicating poetry was spotted early, when she accompanied her family to perform at weddings and special occasions. It wasn’t long before she was performing in the elite salons of early 20th-century Cairo, although her father dressed her as a boy to protect her from any unwelcome interactions with strangers.

In the Egyptian capital she quickly associated herself with the most talented musicians of the day, and from then on she never looked back. She explored the major Arabic song forms of the period, collaborating with composers and poets. She dabbled in film, negotiated record deals, and when public service broadcasting began in the 1930s, she secured herself a monthly slot on national radio. In awe of her talent and mesmerising presence, the Arab world practically came to a standstill whenever she was heard on the airwaves.

Joining Bridget Kendall to explore Umm Kulthum’s life are Virginia Danielson, author of The Voice of Egypt: Umm Kulthum, Arabic Song and Egyptian Society in the 20th Century; Salwa el-Shawan Castelo-Branco, professor of ethnomusicology at the New University of Lisbon and president of the International Council for Traditional Music; and Yara Salahiddeen, whose current research at the University of Oxford focuses on music-making in 19th and early 20th century urban Egyptian society.

Alexandre Dumas: The man behind the Musketeers Dec 03, 2020

The word 'swashbuckling' is often used to describe the novels of Alexandre Dumas the Elder, the creator of D’Artagnan and the Three Musketeers, the Count of Monte Cristo and the Man in the Iron Mask. But Dumas himself led a life as colourful as many of his gallery of rogues, villains and heroes. Having grown up in poverty, he found employment in the household of a future king of France. He was prolific on the page and pretty active away from it. At first with a series of highly successful plays and then with serialised novels, his production house churned out hundreds of thousands of pages of gripping narrative. He had pet projects like building a mansion and theatre, he had countless mistresses and he frequently found himself in legal disputes and on the run from debt collectors.

In the 150th anniversary year of Dumas’ death Rajan Datar explores the writer's life and work with Claudie Bernard, professor of French Literature, Thought and Culture at New York University; Daniel Desormeaux, professor of Arts and Sciences at Johns Hopkins University in Baltimore; Sylvain Ledda, professor of 19th Century Literature at Rouen University in France; and Anne O'Neil-Henry, associate professor of French and Francophone Studies at Georgetown University in Washington.

Unlocking the mysteries of cuneiform tablets Nov 26, 2020

Cuneiform is an ancient writing system distinguished by wedge-shaped marks made into clay. It developed over 5,000 years ago in Ancient Mesopotamia. At its height it was used to write languages across the ancient Middle East, from Iran to Syria to Anatolia in Turkey. But cuneiform writing fell out of use about 2,000 years ago in favour of alphabetic scripts. When scholars in the 19th century finally managed to redecipher it, they discovered fascinating insights into the culture and rituals of people living in the ancient Middle East, unlocking texts that have changed our understanding of history, including The Epic of Gilgamesh, the Code of Hammurabi and The Amarna Letters of Ancient Egypt. And cuneiform has even seen something of a revival in modern-day Iraqi visual culture. Joining Rajan Datar to discuss cuneiform script are Professor Eleanor Robson of University College London, Dr Mark Weeden of SOAS, University of London and Ahmed Naji, author of 'Under The Palm Trees: Modern Iraqi Art with Mohamed Makiya and Jewad Selim'.

First impressions: The printing press Nov 19, 2020

When the fifteenth century German entrepreneur Johannes Gutenberg pioneered the printing press, he made an indelible mark on the history of communication. Here was a way to print pages in high quality and high quantities, using methods more efficient than had ever been seen before.

Rajan Datar and guests explore the story of how the printing press was born, and how it changed our world - from the birth of the modern book to the rise of the information society, and the transformation of fields including scholarship and religion.

Rajan is joined by art historian Hala Auji, publisher Michael Bhaskar, scholar Cristina Dondi and the writer John Man.

The woman whose cells changed medical history Nov 12, 2020

The story of a young mother who unwittingly left behind a vast medical legacy. Henrietta Lacks died of cancer in Baltimore in 1951 and though she never gave consent to her tissue being used for research, doctors at the time found that her unusually virulent tumour had extraordinary properties. As her cells multiplied in labs around the world, they helped make possible all sorts of medical breakthroughs, from the polio vaccine to cancer drugs and IVF treatment. But it took the Lacks family decades to discover what was going on, and the story raises questions for all of us – about medical ethics, institutional racism, and our right to privacy.

Joining Bridget Kendall to discuss this remarkable story are: Henrietta Lacks' grandson David Lacks Jnr who's on the board of the HeLa Genome Access Working Group; the award-winning science writer, Rebecca Skloot, whose book The Immortal Life of Henrietta Lacks brought the story to the world's attention a decade ago; and Sir John Burn, Professor of Clinical Genetics at Newcastle University.

Comenius, a pioneer of lifelong learning Nov 05, 2020

Teaching not by rote but through play? That's credited to the 17th-century Czech pastor and thinker called Jan Amos Comenius. Splitting schoolchildren up into year groups? That's Comenius. Universal education for all, rich and poor? That's down to him too. Nearly four centuries ago, Comenius came up with principles of modern education but they were only implemented hundreds of years after his death. That these ideas are now so widely accepted obscures the fact that they were ground-breaking - indeed too radical - in his day. Comenius lived through turbulent times: the devastating Thirty Year served as the backdrop to much of his life. He was suffered personal tragedy during the bitter battles between Protestants and Catholics in Europe and spent most of his adult life in exile. Joining Rajan Datar to analyse the contribution to modern thinking made by Comenius in this, the 350th anniversary year of his death are Dr. Vladimir Urbanek, Head of the Department of Comenius' Studies and Early Modern Intellectual History at the Czech Academy of Sciences in Prague; Howard Hotson, Professor of Early Modern Intellectual History at Oxford University; and Dr. Yoanna Leek from the Faculty of Education Sciences at Lodz University in Poland.

Dido of Carthage: A love story gone wrong Oct 29, 2020

A Phoenician princess, who fled into exile to escape the cruel king of Tyre, sailed across the Mediterranean Sea to North Africa, where she founded the great city of Carthage in the ninth century BC. Well, that is one story about Dido, or Elissa, as she is known in today's Lebanon and Tunisia. Another, from the Roman poet Virgil, puts her at the centre of a tragic love story: first entranced, then abandoned by the wandering Trojan hero Aeneas, Dido curses him and takes her own life. So who was the real Dido? Was she a powerful independent queen, or a victim - a spurned lover? And did she exist at all? Bridget Kendall is joined by Josephine Quinn, professor of Ancient History at Oxford University, and the author of the book In Search of the Phoenicians; Helene Sader, professor of Archaeology at the American University of Beirut, and the author of The History and Archaeology of Phoenicia; Roald Docter, professor of Archaeology at Ghent University and the editor of Carthage Studies; and Boutheina Maraoui Telmini, professor of Punic History and Archaeology at the University of Tunis.

Paul Robeson: Singer, actor and civil rights activist Oct 22, 2020

The multi-talented Paul Robeson could have turned his hand to pretty much anything he set his mind to: lawyer, athlete and linguist were just some of the career paths he could have taken. But he chose to become an actor and singer, and in doing so reached into the lives of huge numbers of people as one of the most popular American entertainers of his time.

Outspoken on the issues of racism, colonialism and the rights of workers, he used his popularity to campaign against the injustice he saw in many countries across the world – not just injustice suffered by his fellow African Americans.

During the Cold War, his support for Soviet-style communism was deemed unacceptable by the American establishment, and some set out to destroy his career.

Joining Bridget Kendall to examine Paul Robeson’s life are Dr Gerald Horne, the Moores Professor of History and African American Studies at the University of Houston and the author of Paul Robeson: The Artist as Revolutionary; Dr Shana L Redmond, Professor of Musicology and African American Studies at the University of California, Los Angeles, and the author of Everything Man: The Form and Function of Paul Robeson; and Tayo Aluko whose one-man play Call Mr Robeson has won numerous awards and toured countries around the world since its premiere in 2007.

Telling the time: From sundials to satnav Oct 15, 2020

Many of us can find the time of day quickly and accurately but where did the idea of time keeping originate and how did our ancestors manage without the instant access we take for granted today?

From ancient shadow and water clocks to the latest super accurate optical clocks, Bridget Kendal explores time keeping with the Curator of the Royal Observatory in London, Dr Louise Devoy; the Director of the Museum of the History of Science in Oxford, Dr Silke Ackermann; and watch and clock expert Grégory Gardinetti from the Fondation de la Haute Horlogerie in Geneva.

Writer Jorge Luis Borges: Mixing the magical with the mundane Oct 08, 2020

‘We accept reality so readily - perhaps because we sense that nothing is real.' A typically paradoxical quote from the Argentinian writer Jorge Luis Borges whose works have become classics and an influence not just on many Latin American novelists but on countless authors around the world. Yet although he is one of the most analysed figures in literature, even his greatest fans struggle fully to explain his writing. So who was Jorge Luis Borges? And what is it that makes his writing so compelling?

To find out, Bridget Kendall talks to three Borges experts: Dr. Patricia Novillo-Corvalán, from the University of Kent, author of Borges and Joyce, An Infinite Conversation; Prof. Evelyn Fishburn, from University College London, author of Hidden Pleasures in Borges’s Fiction; and Edwin Williamson, Professor at Oxford University and editor of the Cambridge Companion to Jorge Luis Borges.

Elizabeth Fry: 'The angel of prisons' Oct 01, 2020

Life behind bars in English prisons in the early nineteenth century was, to put it mildly, grim. Prisons at the time were often damp, dirty and over-crowded. Common punishments included shipping convicts to colonies like Australia - and many crimes carried the death penalty. And the poor suffered most of all, because they couldn’t buy privileges like extra food rations. Into all this walked a woman known as the "angel of prisons", Elizabeth Fry. She was one of the major driving forces behind a new way of thinking about prisons – one that stressed that improving conditions for prisoners and treating them with humanity would lead to better outcomes and lower re-offending rates. A Christian philanthropist from a large Quaker family, her ideas were taken up across much of Europe, and she became something of a celebrity in Victorian England.

Joining Rajan Datar to discuss her work and legacy are:

Averil Douglas Opperman, author of a biography of Elizabeth Fry called 'While It Is Yet Day'; Criminal barrister, Harry Potter, author of 'Shades of the Prison House – A History of Incarceration in the British Isles'; And Rosalind Crone, historian and author of 'The Guide to the Criminal Prisons of Nineteenth-Century England'.

The 1921 Tulsa Race Massacre Sep 24, 2020

Greenwood was an African American success story: a thriving, wealthy district of Tulsa. Over the course of two days at the end of May 1921 it was the scene of looting, rioting and murder. After 18 hours the area was razed to the ground by vigilantes. One eye witness said it looked like the world was coming to an end with bullets.

Nobody to this day has been able to establish the true number of deaths. Some put the figure in the hundreds, with casualties on both sides. The community rebuilt itself however, and today it’s the focus of a multi-million dollar investment and education programme.

Joining Rajan Datar to examine the events of 1921 are Carol Anderson, the Charles Howard Candler Professor of African American Studies at Emory University and the author of White Rage; Hannibal B Johnson, lawyer and author of numerous books on the city’s history including the forthcoming Black Wall Street 100: An American City Grapples With Its Historical Racial Trauma and John W Franklin, cultural historian and former senior manager at the Smithsonian National Museum for African American History and Culture in Washington DC. He’s also the grandson of Buck Colbert Franklin, a lawyer and leading community figure who survived the massacre.

There is language in the programme which reflects the historical records and accounts recorded at the time of the events in Tulsa, which some listeners may find offensive.

Queen Tamar: The myth of a perfect ruler Sep 17, 2020

Queen Tamar was one of Georgia’s most iconic and colourful rulers, a powerful medieval sovereign who controlled large parts of the Caucasus and the eastern side of the Black Sea and forged strong cultural links with both the Byzantine West and the Persian South. Her influence extended beyond the battlefield: she presided over the last phase of the Georgian ‘Golden Age’ which saw the building of classic Georgian churches and a flowering of the Arts that produced one of Georgia’s most important poets. So who was Queen Tamar? How did she rise to power and outmanoeuvre her enemies? And why do the myths about her rule publicised by her faithful chroniclers persist till today? Bridget Kendall is joined by Dr. Ekaterine Gedevanishvili, Senior Researcher at the National Centre for the History of Georgian Art in Tbilisi; Alexander Mikaberidze, Professor of History at Louisiana State University; Dr. Sandro Nikolaishvili, researcher at the University of Southern Denmark, who works on retracing connections between the Byzantine and Georgian worlds; and Donald Rayfield, Emeritus Professor of Russian and Georgian at Queen Mary, University of London.

Who were the Huguenots? Sep 10, 2020

The Huguenots gave the word 'refugee' to the English language - they were French protestants escaping religious persecution, who fled from France to neighbouring states between the 16th and 18th centuries. Despite their early experience of violence and religious upheaval, they are widely celebrated for their contribution as migrants, famously as silk weavers and silversmiths, traders and teachers.

Joining Bridget Kendall to discuss the Huguenots and their global legacy are three experts: Owen Stanwood is Associate Professor of History at Boston College in the United States and is the author of 'The Global Refuge: Huguenots in an Age of Empire'; Ruth Whelan is Professor of French at Maynooth University in Ireland, where she researches the religious and intellectual culture of French Protestants between 1680 and 1730; and Kathy Chater is a London-based historian and genealogist. She’s the author of 'Tracing Your Huguenot Ancestors'.

Smallpox: The defeat of the speckled monster Sep 03, 2020

As scientists around the world look for ways to combat COVID-19, the only human disease ever to be eradicated by vaccination could provide us with some insights.

Since 1979 the world has been free from smallpox. But before the WHO’s concerted effort to eradicate the disease, it claimed millions of victims every year. It’s estimated that 300 million people died from it in the 20th century alone, and those who survived were often left with disfiguring scars or sometimes blind.

Such was its destructive power, some commentators have argued that smallpox changed the course of human history, wiping out indigenous populations and allowing imperial nations to colonise new territories with little resistance.

The English doctor Edward Jenner developed the first vaccine against smallpox in 1796. This procedure laid the foundations for immunisation programmes which have saved hundreds of millions of lives ever since, by giving people protection against a whole range of diseases - not just smallpox.

Joining Bridget Kendall to discuss the history of smallpox are Professor Gareth Williams, author of Angel of Death: The Story of Smallpox; former head of the Centers for Disease Control and Prevention in the US, Dr Bill Foege who worked on the WHO smallpox eradication programme in Africa and India, and Dr Anne-Marie Moulin, author of The Vaccine Adventure.

Lal Ded, mystical Kashmiri poet Aug 27, 2020

There is a great deal of mystery surrounding the poems attributed to the female Kashmiri poet, mystic and sage known as Lal Ded or Lalla. There are no records of her life but what is beyond doubt is the vitality, wisdom and endurance of her work. Her poems, usually just four lines long, have been around for centuries and remain so popular that some of them have passed into everyday speech in Kashmir. Lal Ded’s poems are also celebrated for their independence of thought and spirit and for challenging stereotypical images of what counts as female poetry during the Middle Ages. Rajan Datar is joined by leading Kashmiri writer and translator Neerja Mattoo; poet Ranjit Hoskote, author of a complete rendering of Lalla's poetry into English; Andrew Schelling, professor of poetry at Naropa University in Colorado who has translated and edited Indian devotional poetry for many years; and Dean Accardi, professor of history at Connecticut College who specialises in medieval Kashmir.

Secrets of the Great Pyramid Aug 20, 2020

The Great Pyramid of Giza in Egypt is one of the greatest wonders of the ancient world. It is the largest pyramid ever built and even today, with advanced satellite and thermal imaging and other high tech science, we don’t know everything about the pyramid- exactly what’s inside or how it was built. To explore the history of The Great Pyramid - also known as the Pyramid of Khufu, after the Pharaoh who commissioned it as his tomb - Rajan Datar is joined by Salima Ikram, Distinguished University Professor and Egyptology Unit Head at the American University in Cairo, space archaeologist Sarah Parcak, a National Geographic fellow and Professor at Birmingham University Alabama in the USA, and Professor Joyce Tyldesley, an archaeologist and Egyptologist from the University of Manchester in the UK.

Ray Bradbury, a master of science fiction Aug 13, 2020

”People ask me to predict the future, when all I want to do is prevent it.” Ray Bradbury has been acclaimed as the writer most responsible for bringing modern science fiction into the literary mainstream but, as the quote above shows, he regarded himself as the author of modern philosophical fables, rather than a sci-fi writer. In his dystopian works, such as Fahrenheit 451, he holds up a mirror to contemporary society and then transposes it into fantastical and futuristic scenarios. Bradbury was a prolific writer who tried his hand at everything from poems and novels to TV and radio scripts but it’s his early short stories which he produced in his twenties that are perhaps the most imaginative.

To mark the centenary of Bradbury’s birth, Rajan Datar is joined by three Bradbury experts to help him navigate through the author’s prodigious output: Professor Jonathan Eller from Indiana University who is also the Director of the Center for Ray Bradbury Studies; Dr. Miranda Corcoran who teaches American literature at University College Cork with particular interest in science fiction, horror and the gothic; and Dr. Phil Nichols who combines research into Bradbury's TV and other media work with the teaching of Film and Television Production at Wolverhampton University.

The Fall of the Roman Empire Aug 06, 2020

In 476, the last of the Roman emperors in the West was deposed; in 1776, historian Edward Gibbon wrote “The History of the Decline and Fall of the Roman Empire”, and Rome’s fate became a major point of comparison for all empires. In Gibbon's view, instead of inquiring why the Roman empire was destroyed precisely 1300 years before, we should rather be surprised that it had subsisted so long. Ever since, there has been a fascination with what changed in Rome in 476 and why, and whether there were more significant changes earlier or later than that date and, importantly, what stayed the same.

In this edition of The Forum, Rajan Datar explores the ideas about Rome’s Fall with Sarah E. Bond, Associate Professor of History at the University of Iowa, USA; Meaghan McEvoy, Lecturer in Byzantine Studies at Macquarie University in Sydney, Australia; and Peter Heather, Professor of Medieval History at King’s College London, UK.

Picasso, artist of reinvention Jul 30, 2020

Pablo Picasso is commonly regarded as one of the most influential artists of the 20th Century, changing our way of seeing with his radical innovation and revolutionary approach. As pioneer of Cubism, godfather to the Surrealists, and creator of the enduring anti-war painting Guernica, he produced thousands of paintings in his lifetime, not to mention his sculptures, ceramics, stage designs, poetry and plays.

Rajan Datar discusses his life and work with curators Ann Temkin and Katharina Beisiegel, and art historian Charlie Miller.

Tolstoy: War and Peace Jul 23, 2020

'War and Peace' by the Russian novelist Leo Tolstoy charts the story of Russia during the Napoleonic wars of the early 19th century, covering the pandemonium and brutality of the battlefield, as well as the equally intense dramas and loves of several families. It is a monumental novel, tracking the fortunes of dozens of brilliantly drawn individuals, with a cast of more than six hundred characters, both historical and fictional. So why is 'War and Peace' still such a compelling masterpiece, and why did Tolstoy later disown it?

Joining Bridget Kendall are Dr Galina Alexeeva, head of Research at Yasnaya Polyana, Tolstoy’s former country estate in Russia; Andrei Zorin, Professor of Russian at Oxford University and author of a new biography of Tolstoy, and Professor Donna Orwin, author of 'Simply Tolstoy', who’s from the University of Toronto in Canada.

Chaucer, father of English poetry Jul 16, 2020

Geoffrey Chaucer has been called the father of English poetry and the greatest poet in English before Shakespeare. He is best known for The Canterbury Tales, stories told by a band of pilgrims on their way from London to the shrine of Thomas Becket who was murdered in Canterbury Cathedral two centuries before. Chaucer’s was an age of plague, war and revolt and his pilgrims bring insight into the life and values of those tumultuous times, from the bawdy Miller and the earthy Wife of Bath to the corrupt Pardoner and the Knight whose chivalry was increasingly out of step with the times.

Bridget Kendall explores the range of Chaucer’s world with Emily Steiner, Professor of English at University of Pennsylvania; Mary Flannery, Professor of Medieval English Studies at Bern University; and Anthony Bale, Professor of Medieval Studies at Birkbeck College, University of London.

Up close with tango Jul 09, 2020

Tango is easy to recognise: those daring steps, the tight hold of the dancing partners, the intense yet melancholy music dominated by the plaintive sounds of the bandoneon. But if you ask what exactly tango is and where it came from, the answer may not be so immediately clear – because it’s more than a genre of music, more than just a style of dance. To get insights into the roots, the culture and even the magic of tango, Rajan Datar is joined by leading tango historians Maria Susana Azzi, Christine Denniston and John Turci-Escobar.

Valkyries: Fierce women of war Jul 02, 2020

In Norse mythology, Valkyries were women who went out into battles to choose the slain warriors who deserved to be in Valhalla, Odin’s place in Asgard, to carry on fighting in preparation for the final apocalyptic confrontation of Ragnarok, between gods and giants. Fighters would see the Valkyries flying through the air or riding on horses, with shields and helmets, some saving the lives and ships of those they favoured, some causing death to those they disliked. These stories of Valkyries and Valhalla offer insights into the lives and values of the people who told them, with the possibility that human women went into battle too.

Bridget Kendall is joined by Sif Rikhardsdottir, Professor and Chair of Comparative Literature at the University of Iceland, Marianne Hem Eriksen, Associate Professor of Archaeology at the Museum of Cultural History, University of Oslo in Norway, and Judith Jesch, Professor of Viking Studies at the University of Nottingham, in the UK.

Silk routes: 2000 years of trading Jun 25, 2020

China, Iran, Afghanistan, Syria, Uzbekistan and India: if you went to any of these places a thousand years ago, you would find goods and produce from the others. But how did they get there and why? This week’s Forum explores the ancient pattern of trading networks which criss-crossed the plains, deserts and mountains of China, Central Asia and points further West, and which encouraged not just the exchange of commodities such as silk, paper and horses but ideas and people too. Bridget Kendall talks to Valerie Hansen, professor of history at Yale University who has a particular interest in trade and exchanges across Eurasia; historian Dr. Susan Whitfield, former curator of the Central Asian collections at the British Library in London; and Tamara Chin, professor of comparative literature at Brown University whose work focuses on ancient China.

Bertha von Suttner: A champion of peace Jun 18, 2020

Bertha von Suttner’s path to becoming a leading 19th-century pacifist and the first woman to win the Nobel Peace Prize was far from straightforward. The product of the aristocratic and militaristic world of 19th century Bohemia, as a young woman von Suttner eloped to the Caucasus and turned her hand to writing for a living. On her return to Europe she published an acclaimed anti-war novel, Lay Down Your Arms, a work that marked the start of her quest for disarmament. Her long friendship with Alfred Nobel finally bore fruit in the Swedish industrialist’s last will which included the Peace Prize.

Bridget Kendall is joined by Dr. Barbara Burns, Reader in German at Glasgow University, and the editor of a new English edition of Lay Down Your Arms; Dr. Peter van den Dungen, former Lecturer in Peace Studies at the University of Bradford and until recently General Coordinator of the International Network of Museums for Peace; and musician Stefan Frankenberger, the author of an audio book called The Unknown Soldier, In memory of Bertha von Suttner.

Joan of Arc: Making a martyr Jun 11, 2020

Born more than six hundred years ago, Joan of Arc is regarded as a French national heroine – a peasant girl who, inspired by saintly visions, battled to break the Siege of Orléans and see Charles VII finally crowned King of France in a grand cathedral. But in 1431, she was burned at the stake.

Bridget Kendall and guests discuss the life and death of this medieval teenage celebrity who helped to shape the course of the Hundred Years War with England. They also reflect on her status as an enduring symbol in popular culture through the ages, including on the stage and the big screen. Bridget is joined by film scholar Robin Blaetz, and historians Juliet Barker, Xavier Helary and Daniel Hobbins.

Babylon, city of wonders Jun 04, 2020

With its Hanging Gardens and huge walls, Babylon was celebrated as one of the Seven Wonders of the ancient world; to the Israelites enslaved there under Nebuchadnezzar, it was a lasting emblem of oppression and depravity, where they wept as they remembered Zion. It is only in the last two hundred years that Babylon's fuller history has been unearthed, both the remains of its buildings and a huge number of clay tablets covered in writing, revealing a complex world that created epic stories, powerful people and an understanding of science and the stars, and it was their 60 based numbering system that led to our 60 seconds in a minute and 60 minutes in an hour. It has been called a cradle of civilisation.

Bridget Kendall explores the reputation of Babylon and its contribution to the world with four experts: Frances Reynolds, Shillito Fellow in Assyriology at the Oriental Institute, University of Oxford; Grant Frame, Professor of Assyriology at the University of Pennsylvania and Curator of the Babylonian Section of Penn Museum; Daniel Schwemer, Chair of Ancient Oriental Studies at the University of Würzburg; and Jaafar Jotheri, Assistant Professor in Geoarchaeology at the University of Al-Qadisiyah, Iraq.

Aesop and the Fables May 28, 2020

Aesop, with his tales of tortoises and hares, foxes and grapes, and wolves in sheep's clothing has been a part of world literature for over two thousand years. Since the time of the Ancient Greeks successive generations have drawn moral lessons from his fables, and over history his animals' exploits have been used to support differing ideals. Malcolm X was a fan, as was Imperial Britain, the Nazis had their version and the Trade Union movement published the fables too. There are over 700 fables, and they are supposedly written by a black slave far clever than his philosopher master.

Bridget Kendall traces the origin and meaning of Aesop's fables and explores what they can teach us about understanding our own extraordinary times with three world experts: Edith Hall, Professor of Classics at Kings College London; Vayos Liapis, Professor of Theatre at the Open University of Cyprus; Dan-el Padilla Peralta, Associate Professor of Classics at Princeton University.

Goethe: The story of colour May 21, 2020

The German polymath Johann Wolfgang von Goethe considered his monumental book known in English as The Theory of Colours to be his greatest achievement. The book is a record of hundreds of Goethe’s observations about the way colour affects our mood, as well as a long and heated polemic with Isaac Newton’s colour theory. Goethe’s understanding of light and colour was scientifically flawed yet his book had a surprisingly strong influence on the fine and applied arts. To find out why, Bridget Kendall talks to art historian Alexandra Loske, colour writer Victoria Finlay and designer Odette Steele. Alexandra Loske is an art historian who teaches at the University of Sussex, Curator at the Royal Pavilion and Brighton Museums and co-editor of the book Languages of Colour; Victoria Finlay is a writer, former arts editor of the South China Morning Post and the author of Colour, Travels through the Paintbox and The Brilliant History of Color in Art; Odette Steele is a Zambian textile designer recent and a graduate from the London College of Fashion at the University of the Arts, London.

The California Gold Rush May 14, 2020

From 1849, hundreds of thousands of prospectors from across the USA headed for California in the hope of finding gold. Some made great fortunes, and there was a new Californian dream for these 49ers, willing to risk everything and, if they failed, to try again. California was to become the engine house of the US economy, while expanding so rapidly that it unbalanced the free and slave-owning states and hastened the USA towards civil war. Yet the new arrivals also drove out competing miners from around the Pacific who had reached the goldfields first, and destroyed the lives of Native Americans there, and excluded Chinese people who had begun to settle, with lasting consequences.

Joining Bridget Kendall to explore who won and who lost in the California Gold Rush are Cliff Trafzer, Distinguished Professor of History at the University of California, Riverside; Mae Ngai, Professor of History at Columbia University, and author of the forthcoming book The Chinese Question, a study of Chinese gold miners; and HW Brands, Professor of History at The University of Texas at Austin and author of Dreams of El Dorado: A History of the American West.

The 1918 Spanish Flu: The mother of all pandemics Apr 30, 2020

A century ago a deadly flu virus swept the planet, uniting the world in a disaster on a par with World War One.Over 50 million people died. Social distancing was put in place but drugs were ineffective, there was no vaccine, and in many places medicine could not cope. The world recovered but was never the same again.

What can the last great pandemic teach us about how to combat Covid-19 today?

Three world experts join Bridget Kendall: Laura Spinney, science journalist and author of Pale Rider: The Spanish Flu of 1918 and How it Changed the World;. Svenn Erik Mamelund, historical demographer and research professor at Oslo Metropolitan University; Siddharth Chandra, director of the Asian Studies Centre and professor at James Madison College, Michigan State University.

Gerard Mercator: The man who revolutionised mapmaking Apr 23, 2020

It’s the map of the world we all recognise today, but until Gerard Mercator came up with his elegant solution in 1569, the question of how to turn the earth’s three dimensional sphere into a flat image had long flummoxed mapmakers. Nearly 500 years later, Mercator’s model is still the standard for modern mapmaking. What makes it so enduring?

Joining Rajan Datar to discuss the man who defined the way we see the world are geographer and explorer Nicholas Crane, philosopher Emily Thomas and professor of cartography Philippe De Maeyer.

Gretta Cousins: champion of Irish and Indian women Apr 16, 2020

How many people can lay claim to playing a key role in three different 20th century protest movements across the world, each of which largely succeeded in their aims? Margaret ‘Gretta’ Cousins, the daughter of a minor court official from Boyle in Ireland and a musician by profession certainly can. The common thread in all of these battles for this driven, feisty activist was the demand for equality for women: Gretta Cousins spent time in jails in Ireland, England and India for her beliefs and remained a catalyst for change throughout her life. As a suffragette she was involved in high-profile direct action in London and Dublin, while in India she not only contributed to the improvement of women’s lives but also became the country’s first female magistrate.

Rajan Datar is joined by historians Dr. Margaret Ward from Queen's University in Belfast, Dr. Jyoti Atwal from Jawaharlal Nehru University, New Delhi and University of Limerick and Dr. Emily Rook-Koepsel from the University of Pittsburgh.

Natsume Soseki: Japan’s great novelist Apr 09, 2020

Natsume Soseki is one of the greatest writers in the history of Japan. The backdrop to his work is the disorientation and social anxiety of the early 20th Century as Japan undertook rapid modernization after centuries of being closed to the world. Soseki has had a huge influence on generations of Japanese authors and has obsessed some international artists. His work is taught to generations of school children in Japan and greatly admired by scholars but remains obscure to much of the rest of the world. Why? Joining Bridget Kendall to discuss the life and work of Japanese writer Natsume Soseki: The author and critic Damian Flanagan; Michael Bourdaghs, Professor of East Asian Languages at the University of Chicago; and Reiko Abe Auestad, Professor of Culture Studies and Oriental Languages at the University of Oslo.

In search of the good life: Epicurus and his philosophy Apr 02, 2020

The popular view of an Epicurean is that of somebody who focuses on pleasure as our guiding principle, indulging in the finer things of life to achieve happiness. And yet what the Ancient Greek philosopher Epicurus understood by pleasure was far more nuanced. In fact, Epicurus and his followers advocated a simple lifestyle, withdrawn from society, where we are content with little. What is perhaps less known is how Epicurean writings on physics foreshadowed some of the most significant developments in early modern science – including Darwin’s theory of evolution and even Heisenberg’s uncertainty principle. Joining Bridget Kendall is Catherine Wilson, visiting Professor at the Graduate Centre of the City University of New York, and the author of various works on Epicureanism, including How to Be an Epicurean: The Ancient Art of Living Well; Dr Sonya Wurster, Honorary Fellow at La Trobe University in Australia who’s working on a book about the Epicurean philosopher Philodemus; and philosopher and historian David Sedley, Emeritus Laurence Professor of Ancient Philosophy at the University of Cambridge, and the author of numerous publications on Greek and Roman thought.

Artemisia Gentileschi: The painter who took on the men Mar 26, 2020

One of the most celebrated female painters of the 17th century, Artemisia Gentileschi was the first woman to become a member of the Academy of the Arts of Drawing in Florence. Through her talent and determination - and despite massive obstacles - she forged a 40-year career, and was collected by the likes of Charles I of England and Philip IV of Spain. But after her death, it wasn’t until the 20th century that people began to reinterpret her work in the light of her remarkable life story, including the well-documented fact that she was raped at the age of 17 by fellow painter, Agostino Tassi.

Joining Bridget Kendall to discuss the life and work of Italian Baroque artist, Artemisia Gentileschi are four experts: Letizia Treves is curator of the 2020 Artemisia exhibition at London’s National Gallery; Mary Garrard is Professor Emerita of Art History at American University in Washington DC; Jesse Locker is Assistant Professor of Italian Renaissance & Baroque Art at Portland State University; and Patrizia Cavazzini is Research Fellow at the British School at Rome, Italy.

Guide dogs for the blind: A history Mar 19, 2020

We are now familiar with dogs helping people with sight loss but where did the idea come from? And how have the ways of selecting, training and using guide dogs changed over time?

Bridget Kendall explores the history of guide dogs with Pieter van Niekerk, Head of Public Relations for the South African Guide-Dogs Association and with Karin Floesser, one of the guide dog leaders of the German Federation for the Blind and Partially Sighted. Bridget is also joined by journalist and educator Miriam Ascarelli, biographer of Dorothy Harrison Eustis, the philanthropist who in the 1920s co-founded the American Seeing Eye school, and she hears from Michael Hingson, a blind survivor of the 9/11 attacks.

Oscar Niemeyer: Brazil's king of curves Mar 12, 2020

Best known for his curvaceous buildings and his design of Brasilia, Oscar Niemeyer was one of Brazil’s greatest architects and a leading pioneer of modernism. During his seven- decade career, Niemeyer designed hundreds of remarkable buildings not just in his native Brazil but also in Europe and as far afield as Algeria. His experimentation with reinforced concrete produced organic curved shapes that were a significant departure from the austere style of European modernism. An ardent communist, Niemeyer hoped his beautiful buildings would be for all sections of society to enjoy, but how does his vision and influence endure today, and are his striking creations still functional and sustainable?

Joining Rajan Datar to discuss Oscar Niemeyer and his work are Professor Richard Williams from the University of Edinburgh and the author of “Brazil: Modern Architectures in History”; the Brazilian architect and lecturer at the University of Bath, Dr Juliana Calabria Holley, and Maria Paz Gutierrez, Associate Professor of Architecture at the University of California, Berkeley.

Haile Selassie: the last emperor of Ethiopia Mar 05, 2020

Emperor Haile Selassie was the last in the line of Ethiopia’s ancient monarchy. During his long rule he was revered as an international statesman and reformer, demonised as a dictator, and even worshipped as a God incarnate by the Rastafarians of Jamaica. He was without doubt a controversial figure, but achieved a status in the global arena previously unheard of for an African ruler.

Bridget Kendall discusses Haile Selassie’s life and legacy with Prince Asfa-Wossen Asserate, political analyst and author of ‘King of Kings: The Triumph and Tragedy of Emperor Haile Selassie I of Ethiopia’, who is also the great-nephew of Haile Selassie; Gerard Prunier, Independent Consultant on Eastern and Central African affairs, and former Director of the French Centre for Ethiopian Studies in Addis -Ababa; and Laura Hammond, an anthropologist specialising in Ethiopia at the School of Oriental and African Studies, University of London.

Emilie du Chatelet: a free-spirited physicist Feb 27, 2020

Emilie du Chatelet was esteemed in 18th-century France as a brilliant physicist, mathematician, thinker and linguist whose pioneering ideas and formidable translations were known all across Europe. And yet, after her death in childbirth in her mid-40s she was nearly forgotten, and if she was remembered at all, then as a companion and collaborator of the famous writer Voltaire.

Du Chatelet’s insights into kinetic energy foreshadowed Einstein’s famous equation and her suggestions for experiments with the different colours of light would only be carried out half-a-century after she’d written about them. Plus she was a remarkable personality, determined to live a life of an independent woman, often pushing the boundaries of what was acceptable even in the liberal social circles of her day.

Bridget Kendall discusses du Chatelet’s life and work with history professor Judith Zinsser, Chatelet’s biographer David Bodanis and philosophy professor Ruth Hagengruber.

Man v mosquito Feb 20, 2020

Mosquitos are a fast-adapting, elusive enemy which humans have been trying to combat for thousands of years. As vectors of dangerous diseases, these tiny insects have killed more people in human history than any other animal. So what impact has the mosquito had on our lives? How have humans tried to halt its spread? And who is winning the battle?

Joining Bridget Kendall to discuss the history of man and the mosquito are Dr. Erica McAlister, Senior Curator of Diptera - Flies - at the Natural History Museum in London; Dr. Timothy Winegard, historian and author of The Mosquito: A Human History of our Deadliest Predator; and Dr. Clifford Mutero of the International Centre for Insect Physiology and Ecology (ICIPE) in Nairobi, Kenya, and author of Mosquito Hunter: Chronicles of an African Insect Scientist.

The magic of bronze Feb 13, 2020

From Cellini's magnificent Perseus statue to the humblest of tools, people have been using bronze for at least five thousand years. So what makes bronze such a versatile material, how did we first discover it and why have so many precious bronze art works failed to survive?

Bridget Kendall is joined by Carol Mattusch, Professor Emerita of Art History at George Mason University; Professor Jianjun Mei, from the University of Science and Technology, Beijing and Director of the Needham Institute in Cambridge who specialises in ancient metallurgy; and David Ekserdjian, Professor of Art and Film History at Leicester University.

Also in the programme: Dutch sound artist Floris van Manen follows the key stages of making a bronze bell at Eijsbouts, one of Europe's leading foundries.

Li Bai: The revered Chinese poet Feb 06, 2020

A nomadic wanderer and free-spirited romantic, Li Bai 李白, also known as Li Po, lived some 1300 years ago and yet his poems are still cherished for their wild imagination and effortless artistry. There are many colourful stories about his life but how much can we really know about someone who not only lived so long ago but was also very good at projecting an image of himself as a rebel? And how much of Li Bai's intricate, allusion-rich poetry can be translated successfully into other languages? These are some of the issues that Bridget Kendall discusses with Li Bai scholars Paula Varsano and Wilt Idema, and writer and Li Bai biographer Ha Jin.

Nefertiti: The beguiling Egyptian Queen Jan 30, 2020

A mysterious Egyptian Queen who lived more than 3,000 years ago, Nefertiti still dazzles the modern imagination. Once the wife of a Pharaoh, she might have faded into obscurity, but for the 1912 discovery of an extraordinary bust of her wearing a distinctive flat-topped crown, which captured her very modern beauty and made her into a global celebrity.

Joining Bridget Kendall to discuss the story of Queen Nefertiti are Tarek Tawfik, Associate Professor of Egyptology at Cairo University and former Director General of the Grand Egyptian Museum Project; Christian Loeben, curator of the Egyptian and Islamic Collections at the Museum August Kestner in Hannover, Germany; And Joyce Tyldesley, Reader in Egyptology at the University of Manchester, and author of Nefertiti’s Face: The Creation of an Icon.

The amazing Dr Darwin Jan 23, 2020

Erasmus Darwin was a man of many talents; not only was he a successful physician, a popular poet, an ardent abolitionist and a pioneering botanist, he also worked out how organisms evolve, some 70 years before his grandson Charles’s theories about this revolutionised science. He is credited with many inventions and discoveries including the steering mechanism used in modern cars, the gas laws of clouds and a document copying machine. And he knew how to live life to the full; he fathered at least 14 children and his love of food meant that his dining table had to have a chunk sawn out of it to accommodate his considerable waistline.

Joining Rajan Datar to explore the life and work of this remarkable man are Dr Patricia Fara, Emeritus Fellow of Clare College, Cambridge, and biographer of Erasmus Darwin; Dr Malcolm Dick, director of the Centre for West Midlands History at the University of Birmingham; and Maurizio Valsania, professor at the University of Turin in Italy who specialises in 18th Century intellectual history.

A history of honey Jan 16, 2020

It takes twelve honey bees their entire lifetimes to make one spoonful of honey. From sweetening and preserving food, to treating wounds and sore throats, this sweet, viscous substance has played an important role in nearly every society around the world. In the ancient world, it held religious significance while in the 21st century, scientists are researching how honey could combat lethal diseases and finding ways to identify so-called fake honey.

Joining Rajan Datar to discuss the history of honey are Dr Lucy Long - author of Honey: A Global History and director of the nonprofit Center for Food and Culture in Ohio, USA; Sarah Wyndham-Lewis - writer, Honey Sommelier and co-founder of Bermondsey Street Bees in London, UK; and the Australian microbiologist Dr Shona Blair from Imperial College London who has conducted detailed research into the antimicrobial activity and wound healing properties of honey.

Highlife: The sound of Ghana Jan 09, 2020

The name Highlife is thought to have been coined in the early 20th Century when people on the streets outside clubs reserved for the Gold Coast elite observed the elegant clothes and dancing of the customers inside. Dance band Highlife is just one element of the music which has soaked up all manner of cultural traffic that has marked this part of West Africa. Military bands, gospel, calypso, folk music, ragtime, jazz, reggae, hip hop have all left their imprint on Highlife in a dizzying back-and-forth between Africa and the New World.

When the Gold Coast became the independent state of Ghana in 1957, the music became associated with the search for a national identity. Ghana's first president, Kwame Nkrumah, made Highlife the national dance music, a move that was copied by other emerging nations of West Africa. But from its heyday in the 1960s and '70s, Highlife fell on hard times when a military regime came to power and imposed a curfew. Many musicians left the country to pursue their careers elsewhere. But Highlife proved once more that it could take on new influences, even in exile, and today it is the backdrop to the popular Highlife genre.

With the help of musical examples, Rajan Datar and guests will explore how Highlife works, and discuss how it has grown from its origins in the towns of the Gold Coast to become a commercial success the world over.

Joining Rajan will be guitarist and singer Kari Bannerman, percussionist Oheneba Kofi Adu, producer of the long-running American radio show Afropop Worldwide, Banning Eyre, and Dr Nana Amoah-Ramey, author of Female Highlife Performers in Ghana: Expression, Resistance and Advocacy.

Yiddish: A story of survival Jan 02, 2020

At its height, Yiddish, the language of the European Jews, was spoken by more than ten million people, from Russia in the east to the Netherlands in the West. But by the mid -20th century, these numbers were severely depleted following the Holocaust, and then the creation of the modern-day state of Israel where the speaking of Yiddish was discouraged.

So what does the future hold for this endangered culture with its great tradition of writers and thinkers? Joining Rajan Datar are Aaron Lansky, the director of the Yiddish book centre in the US, who helped save more than a million Yiddish books from destruction; the Jewish-Russian composer and singer Polina Skovoroda Shepherd who writes new songs that still remain within the Yiddish tradition, and Dr Lily Kahn from the Hebrew and Jewish studies department at University College, London, who’s also the author of “Colloquial Yiddish”.

A history of the restaurant Dec 26, 2019

The practice of having your food prepared by strangers in a public place goes back millennia but what makes a restaurant different from the many other dining options is that you can choose from a list of dishes, you can eat at a time of your rather than the cook’s choosing and are usually served by a professional waiter in pleasant surroundings. There were fully-fledged restaurants in 12th-century China catering to a wide range of tastes and budgets. Six centuries later, the first European restaurants in Paris advertised themselves as places that offered good health, rather than just good food. The fashion for French-style dining quickly spread to other countries but it took over a century for the waiters, waitresses and kitchen staff – the very people who are crucial to the success of any restaurant - to be given half-decent working conditions and a modicum of recognition.

Bridget Kendall discusses the development of the restaurant with historians Rebecca L. Spang, Patricia Van den Eeckhout, Luke Barr, Nawal Nasrallah and Christian de Pee.

Eleanor Roosevelt: Redefining the First Lady Dec 19, 2019

A First Lady who broke the mould: Eleanor Roosevelt was not just a hostess at her husband’s side, but a spokeswoman for the disadvantaged, a journalist, and an early civil rights campaigner, who placed herself at the heart of American politics, acting as a prominent adviser and representative for her husband, Franklin Roosevelt, the longest-serving president of the United States. But she was also in office in ‘no ordinary time’ as she put it – a period which encompassed the challenges of the Great Depression and World War Two. So who was Eleanor Roosevelt? What shaped her? How transformative was she? And how should we assess her legacy?

Joining Bridget Kendall to discuss how Eleanor Roosevelt transformed the office of First Lady are Blanche Wiesen Cook, Professor of History at The Graduate Center of the City University of New York and author of a seminal three-volume biography of Eleanor Roosevelt; Maurine Beasley, former Professor of Journalism History at the University of Maryland; and Amy Bloom, Professor of Creative Writing at Wesleyan University and author of White Houses, a novel which explores a secret love affair in the Roosevelt White House.

Ibn Khaldun: 14th Century sage Dec 12, 2019

There were many sides to Ibn Khaldun - a top scholar, a scheming political mastermind, a peripatetic political guru to many a dynasty in North Africa, an inventor of a social science or two. He also spent a month talking to one of the world’s most dangerous conquerors and was imprisoned several times. At a time when the Black Death was raging through the area he suffered terrible personal tragedies. One of his books, the Muqaddimah, is now regarded as a classic text. And how many historians from the Middle Ages have come up with theories that are invoked by modern-day economists and American presidents?

Cyrano de Bergerac: Big-nosed hero Dec 05, 2019

Although the name conjures up the image of a swashbuckling poet with an enormous nose, little is known about the life of the maverick 17th-century writer and philosopher Cyrano de Bergerac. Born four centuries ago, he left behind a play, love letters and a handful of strange travelogues that imagine a journey to the moon.

The sketchy details of his past were a blank canvas for the late 19th-century French playwright Edmond Rostand, who mythologised aspects of Cyrano’s life for his own ends. Immortalising Cyrano on stage, Rostand created a character whose heroism and generosity have resonated with audiences since the play’s premiere in 1897. Cyrano believes himself to be ugly and ridiculous on account of his large nose, and fears that in spite of his talent for romantic poetry he will never be able to win the heart of the woman he loves. Enter the good-looking but inarticulate Christian de Neuvillette, and together they devise the perfect hero whose identity is only revealed at the end of the play.

Bridget Kendall explores the intersection between the real Cyrano and his fictional counterpart with Dr Clémence Caritté, who’s written extensively on Rostand’s Cyrano de Bergerac; Professor Isabelle Moreau from the University of Lyon, co-editor of Seventeenth Century Fiction: Text and Transmission; and Professor John Rodden who lectures in European history at the University of Texas at Austin, USA.

The Scythians: Masters of the steppe Nov 28, 2019

They were the ancient horse lords of the Eurasian steppe, nomadic warriors whose influence extended over thousands of kilometres from Mongolia to the Ukraine. The spectacular gold jewellery and mummified remains preserved in their ancient burial mounds, some the size of a football pitch, tell us they loved colour and precious metal. But what else do we know about the enigmatic Scythians? They left us no written records so we have to rely on testimonies of their neighbours and new archaeological and genetic techniques. One thing seems sure, they knew how to party. Not only do Greek sources repeatedly mention ‘drunken Scythians’ but archaeological evidence confirms feast remnants with hundreds of wine amphorae and ‘purification tents’ filled with hemp smoke.

Bridget Kendall is joined by leading experts on the Scythians: Professor Hermann Parzinger, president of the Prussian Cultural Heritage Foundation, Dr Margarita Gleba from the Ludwig Maximilian University of Munich and Sir Barry Cunliffe emeritus professor from Oxford University.

The Russian civil war: How the Soviets rose to power Nov 21, 2019

The Russian Civil war was a struggle for power at every level – from the villages to the imperial centre, with more than 11 foreign powers involved as well as nationalists, from Ukraine, Poland and the Baltic states, fighting for independence. This conflict, which took place a hundred years ago, between a small group of revolutionaries known as the Bolsheviks and their enemies was one of the most brutal and tragic periods in Russian history, but it was also to shape the new Soviet state that was founded in 1922, and still characterises Russia today.

But why did events of the Russian Civil war end up crushing hopes for democracy after the idealism of the October revolution? And how did a small extremist group like the Bolsheviks manage to take control, despite resistance - not just from the upper and middle classes- but also from peasants and workers? Joining Bridget Kendall to explore these themes further is Laura Engelstein, Professor Emerita of Russian history and author of “Russia in Flames”; Steve Smith, Professor of History at Oxford University who wrote “Russia in Revolution”, and Dr Katya Rogatchevskaia, lead curator of the Russian and East European collections at the British Library in London.

Fridtjof Nansen: Norway's great explorer Nov 14, 2019

Mention famous polar explorers to most people and they will probably come up with the names Scott and Amundsen. But really there should be another name before these, Fridtjof Nansen, a man who can be viewed as a true pioneer of intrepid, indeed death-defying expeditions to the freezing, bleak extremities of the world. He ventured closer than anyone else before him towards the North Pole but this Norwegian national hero was so much more than a character from a boys-own adventure annual. He was a scientist, an early oceanographer, a top class skier, a bestselling author, a diplomat, a humanitarian who spearheaded the repatriation of nearly half a million starving First World War prisoners, a tireless fundraiser for famine relief, the man who gave thousands of stateless people passports and a Nobel Peace prize winner.

Rajan Datar recounts Nansen's remarkable life with the help of historians Robert Marc Friedman and Carl Emil Vogt, writer Marit Fosse and polar explorer Paul Rose.

Rudolf Nureyev: Superstar Russian dancer Nov 07, 2019

From the moment the seven-year-old Rudolf Nureyev saw a ballet on stage in his local theatre, he lived and breathed dance. That overwhelming desire to be on stage carried him throughout his life – from his student days in Leningrad to his defection to the West in a blaze of publicity, from theatres around the world to his final curtain in 1992 when his gaunt body was ravaged by Aids. He made good on his promise: “the main thing is dancing, and before it withers away from my body, I will keep dancing till the last moment, the last drop.”

In a career spanning more than three decades, he brought new audiences to ballet, and gave new meaning to the role of male dancers. He was a pin-up, a performer whose stage presence and artistry was so mesmerising that those who saw him perform in the 1960s have never forgotten the experience. His leaps defied gravity; he gave the impression of floating through the air. But his demands for perfection could make him a difficult person to be with. His temper was as legendary as his dancing. Bridget Kendall explores how Nureyev’s commitment to transcend his childhood in grinding poverty made him one of the world’s most celebrated dancers, with writer Julie Kavanagh, author of Rudolf Nureyev: The Life; writer and translator, Irina Klyagin, who looks after Harvard University’s extensive theatre collection and specialises in Russian ballet; and Thierry Fouquet, vice chair of the board of trustees of the Rudolf Nureyev Foundation who worked with Nureyev during his time at the Paris opera, the home of France’s leading ballet company.

John Harvey Kellogg: The ‘wellness’ pioneer Oct 31, 2019

John Harvey Kellogg is best known, along with his brother, for changing the way the world ate breakfast. But cornflakes were actually a by-product of Dr Kellogg’s lifelong mission to improve the dietary health of patients at his Battle Creek Sanitarium, a once world-famous medical centre and spa in the US state of Michigan that he ran from 1876 to 1943. Here Kellogg preached the art of ‘biologic living’: a healthy vegetable-based diet, avoiding alcohol, cigarettes, caffeine and meat, and getting plenty of exercise and fresh air. This was a revolutionary way of living at the time in the US, and Kellogg’s work influenced many of our current ideas about food and its relationship to bodily health, and the concept of ‘wellness’.

Rajan Datar discusses John Harvey Kellogg’s life story with Howard Markel, Professor of the History of Medicine at the University of Michigan; Laura J. Miller, Professor of Sociology at Brandeis University in Massachusetts; and Brian C Wilson, Professor of Comparative Religion at Western Michigan University.

Indigo: the bluest blue Oct 24, 2019

Indigo: not only one of the seven colours of the rainbow and the dye that makes your jeans look like they do but and a highly valued pigment which is naturally found in some plants and whose use can be traced back at least six thousand years to Peru. Such was the desirability of indigo that along with sugar, cotton, coffee and tobacco it became a major driver for globalised trade and the horrors of slavery. In India it was the source of so much exploitation that a lawyer called Gandhi rose to fame standing up for indigo farmers.

Rajan Datar explores the rich history of the dye with Jenny Balfour-Paul, an Honorary Research Fellow at Exeter University and author of Indigo: Egyptian Mummies to Blue Jeans; Lucille Junkere, an artist and textile researcher with a particular interest in the history of indigo in Nigeria and the Caribbean; and Andrea Sella, a professor of chemistry at University College London who delights his students with all kinds of colourful experiments with indigo.

The Cat: In from the wild Oct 17, 2019

Domesticated cats are thought to have started living alongside humans more than 9000 years ago. Unlike dogs, it's believed cats domesticated themselves, entering the homes of early arable farmers in the Fertile Crescent to control the rodent population. Since then, they've been worshipped, vilified and revered by various societies around the world. Today, they are one of the world's most popular pets, living on every continent except Antarctica and a favourite on the internet, and yet, they will never have that image of loyalty that is associated with dogs.

Rajan Datar welcomes three experts in science, culture and archaeology to discuss the history of the domesticated cat: Katharine Rogers - a Professor Emerita of English Literature from City University of New York and author of numerous books including 'Cat' and 'The Cat and the Human Imagination'; Eva-Maria Geigl - an Evolutionary geneticist at the French National Research Institute CNRS; and John Bradshaw - an anthrozoologist from Bristol University, UK, and author of the book 'Cat Sense'.

Manuela Sáenz: South America’s revolutionary heroine Oct 10, 2019

Manuela Sáenz was an Ecuadorian revolutionary who for many years was most famous for her role as the lover of Simón Bolívar - the Venezuelan military leader who secured independence from Spain for a number of countries in South America between 1819-1830. Sáenz left her British husband for Bolívar, or 'The Liberator' as he was known, and famously saved the leader from an assassination attempt, earning her the name 'Libertadora'. But Sáenz was a political force in her own right, receiving various honours for her work for the revolutionary cause. She continued her involvement in politics right to the end of her life while exiled in Peru, acting as a spy and creating a network of informants.

As many countries in what used to be known as 'Gran Colombia' celebrate 200 years of independence from Spain, Bridget Kendall speaks to three experts about Manuela Sáenz's key role in the independence struggle: Pamela Murray, professor of history at the University of Alabama at Birmingham and author of the biography For Glory and Bolívar: The Remarkable Life of Manuela Sáenz; Matthew Brown, professor in Latin American history at the University of Bristol, UK; and Marcela Echeverri, associate professor at Yale University's Department of History in the United States.

Electric telegraph: the first worldwide web Oct 03, 2019

The invention of the electric telegraph in the mid-19th century brought about a revolution in human communication that some argue rivals the printing press and the internet. Suddenly the ‘tyranny of distance’ could be overcome – messages that once might have taken days or even weeks to arrive could be sent almost instantly using Morse code signals. Soon wires reached across continents and under oceans, connecting the world as never before, and radically changing areas such as commerce, diplomacy, journalism and warfare forever.

Bridget Kendall discusses the telegraph’s extraordinary impact with Roland Wenzlhuemer, Professor of Modern History at the University of Munich; Bruce J Hunt, Professor of History at the University of Texas; and Gillian Cookson, Historian of Engineering and Research Fellow at the University of Leeds.

The history of opium Sep 26, 2019

Made from the simple juice of the poppy, opium is arguably the oldest and most widely used drug in the world. Since prehistoric times it has been used to relieve physical pain and quieten troubled minds. It has enabled medical breakthroughs, and inspired some of the greatest Romantic poets and composers. But opium, and its later derivatives morphine and heroin, has also brought addiction and untold misery and death, destroyed families, and corrupted entire countries. Its trade has provoked wars, and is still making global headlines today, from its production in Afghanistan to the opioid crisis in the United States.

Bridget Kendall explores opium’s long and complex history with Doris Buddenberg, former head of United Nations Office on Drugs and Crime in Afghanistan, and curator of a recent exhibition on opium; Zhou Xun, Reader of Modern History at the University of Essex; and Mike Jay, author and cultural historian, whose books on the history of drug use include ‘High Society’.

Albert Camus: Embracing life’s absurdity Sep 19, 2019

‘There is no sun without shadows, and it is essential to know the night,’ the words of Albert Camus, a writer whose exploration of the absurd nature of the human condition made him a literary and intellectual icon. Camus was born in Algeria but is celebrated in France as one of its great twentieth-century novelists and philosophers. His first publishing success, The Stranger, focused on the absurdity of existence but in his later works, including The Plague and The Rebel, he developed his thoughts on the human instinct to revolt.

But who was Albert Camus? How far were his ideas shaped by his Algerian upbringing and by the turbulent political times he lived through in the 1940s and '50s? Bridget Kendall explores these questions with three Camus experts: Nabil Boudraa, Algerian professor of French and Francophone Studies at Oregon State University, Eve Morisi, professor of French at Oxford University and Samantha Novello, research fellow in Political Philosophy at Verona University.

Fernando Pessoa: The man who multiplied himself Sep 05, 2019

Fernando Pessoa is Portugal’s national poet and a giant of 20th Century literature but he’s also a writer who multiplied himself, who wrote under dozens of alter egos, ranging from an engineer trained in Glasgow in Scotland, to a hunchback who is helplessly lovesick, to a doctor and Latin scholar who’s a fervent Royalist. His masterpiece The Book of Disquiet, considered to be one of the defining works of modernist literature, is equally fragmented - written on scraps of paper and consisting of hundreds of virtually unordered manuscripts. So what makes Fernando Pessoa such a great writer and so relevant today? Joining Rajan Datar to discuss Fernando Pessoa and his many selves are his translator and biographer Richard Zenith, and the literary scholars and Pessoa experts Dr Mariana Gray de Castro and professor Bernard McGuirk.

Einstein: Revolution in time and space Aug 29, 2019

Albert Einstein’s inability to get a job on graduating has given hope to generations of students. Knowing what we know now about the genius scientist, it’s hard to avoid smiling on reading his father’s pleas to physics professors to give his son an academic post.

Perhaps it was just as well that these attempts failed, as the job Einstein eventually secured gave him the opportunity to daydream. Assessing new inventions at the Swiss capital’s patent office, Einstein allowed his imagination to run riot, creating ‘thought experiments’ that questioned centuries of knowledge about time, space and motion. In 1905 he published a series of papers that scientists today still use as a reference point. While Einstein himself didn’t foresee the technological application of his work, his research has since been used as the basis of modern inventions such as the atomic bomb, lasers, solar panels and GPS. Neither did he realise immediately the potential of his theories to help us understand the beginning of the universe.

Rajan Datar explores the complexity of Einstein’s theories as well as what made him tick, with expert guests Janna Levin, professor of physics and astronomy at Barnard College, Columbia University, USA; science historian Jimena Canales, author of The Physicist and the Philosopher: Einstein, Bergson and the Debate that changed our understanding of Time; and Matthew Stanley, professor of the history of science at New York University whose book Einstein’s War: How Relativity Conquered Nationalism and Shook the World was published in 2019.

Imhotep: The man behind The Mummy Aug 22, 2019

Fans of Hollywood cinema may recognise the name Imhotep from the original The Mummy film from 1932, and its various remakes. In the movie, Imhotep (played by Boris Karloff) is an Ancient Egyptian high priest who was mummified alive because he had attempted to resurrect his forbidden lover. Fast forward several thousand years, and an archaeologist brings the mummy back to life, with dangerous consequences.

The real Imhotep was a far cry from this Hollywood invention. A high priest yes, but also possibly the architect of the first monumental building fashioned entirely of stone, the Step Pyramid which dates from around 2,600 BC. Imhotep was also an adviser to one of the most important pharaohs, King Djoser, as text on a statue base found at the Step Pyramid confirms. Later generations revered Imhotep as a sage and a scribe, one of the highest honours a person could be paid in Ancient Egypt. He eventually became linked with the Greek god of medicine, Asclepius, and then worshipped as a saint.

Bridget Kendall journeys through the centuries to understand all the different titles that have attached themselves to this legendary figure, with experts Dr David P Silverman, curator in charge of the Egyptian Section of the Penn Museum and Professor of Egyptology at the University of Pennsylvania, USA; Dr Salima Ikram, Distinguished Professor of Egyptology at The American University in Cairo, Egypt, and Dr Aidan Dodson, Honorary Professor of Egyptology at the University of Bristol in the UK.

Andy Warhol: The prince of Pop Art Aug 15, 2019

"In the future everybody will be world-famous for fifteen minutes” is probably the best known quote attributed to Andy Warhol. Warhol was an American artist who became a superstar in the visual art movement known as Pop Art. He crossed the boundaries between art and celebrity becoming famous for what we now call branding, but the private Warhol was a deeply religious man and to his close relatives was known simply as ‘Uncle Andy’. In a world where some of what he predicted has come true, we look back at the life and work of this iconic figure.

With Bridget Kendall to explore Andy Warhol are Eric Shiner the former Director of the Andy Warhol Museum in Pittsburgh USA and New York Director of London’s White Cube, Professor Jean Wainwright the British art historian and curator and a leading expert on Warhol and Andy Warhol’s nephew, the artist and illustrator James Warhola.

Coco Chanel: French style icon Aug 08, 2019

“I didn’t like my life, so I created my life,” the French fashion designer, Coco Chanel declared. And what a life it was: from her humble beginnings in an orphanage, Chanel blazed a trail as a fiercely independent woman, rising to become the toast of French high society. She mixed with the artists who defined modernism in the 1920s and ‘30s, and created a fashion empire which today is a multi-billion dollar business that still dominates the luxury clothes and accessories market.

The suit, the little black dress and the handbag are just some of the items Chanel shaped in a career which covered much of the 20th century. Luxurious and elegant, but also practical, her designs gave women freedom to move and pursue the kinds of activities which were now opening up as society’s barriers were being broken down.

But the woman herself was a web of contradictions. While she contributed to the emancipation of rich women, she limited her workers’ rights. And controversially, she was involved with a Nazi officer in occupied France during World War II. She even tried to capitalise on Nazi laws to seize back her hugely profitable perfume business, having previously sold the majority shares to a Jewish family.

Joining Bridget Kendall to discuss the complex life of Coco Chanel are dress historian Amy de la Haye, author of Chanel: Couture and Industry and professor at the London College of Fashion; fashion historian Emilie Hammen from the Institut Français de la Mode in Paris; and Madelief Hohé, curator of the fashion and costume department at the Gemeentemuseum in The Hague, and the author of Femmes Fatales: Strong Women in Fashion.

Nineteen Eighty-Four: Orwell's dystopian classic Aug 01, 2019

The vision of the future evoked in George Orwell’s last novel Nineteen Eighty-Four was so terrifying to its first readers that some claimed to be unable to sleep at night. When the book was adapted by the BBC for the new medium of television after Orwell’s death, millions became aware of the novel’s concepts and language which have since seeped into Western popular culture. Big Brother, Room 101, the thought police, doublethink: few novels of the 20th century have had such a lasting impact.

Over the seventy years since its publication, world events have brought Orwell’s vision into focus at various points. The Cold War, the collapse of Communism, the rise of surveillance, and the inauguration of President Trump are among those moments in history which have made readers return to the novel time and again.

Joining Bridget Kendall to discuss the origins of Orwell’s novel and its ongoing relevance are Professor John Rodden, author of George Orwell: Life and Letters, Legend and Legacy; journalist and writer Dorian Lynskey whose biography of Nineteen Eighty-Four, The Ministry of Truth, was published in 2019; and editor of the George Orwell Society Journal Masha Karp, writer of the forthcoming George Orwell and Russia (Bloomsbury Academic).

The Spartans: Ancient Greece’s fighting machine Jul 25, 2019

For over two and a half thousand years the Ancient Greek Spartans have been known for their military might, discipline and self-sacrifice. Recent popular culture has portrayed them as the ultimate fearless warriors, especially ‘the 300’ Spartans who fought to the death at Thermopylae. But where does this image come from, and what do we really know about Spartan society and the peculiar utopia it tried to create? The city-state of Sparta has been admired for its stability, frugality, and the unusual social and sexual freedom of its women. But Sparta was also famous for its brutality towards its huge slave population, its authoritarian rule, and its policy of racial purity and eugenics that would eventually prove its undoing.

Bridget Kendall talks to Christy Constantakopoulou, Professor of Classics and Ancient History at Birkbeck, University of London; Paul Rahe, Professor of History at Hillsdale College in the US; and Angie Hobbs, Professor of the Public Understanding of Philosophy at the University of Sheffield.

Leeuwenhoek: The fabric seller who discovered bacteria Jul 18, 2019

Antonie van Leeuwenhoek opened up a whole new world to us; he was the first to observe bacteria and other microscopic lifeforms which could not be seen by the naked eye. He is now regarded as the father of microbiology and yet he had neither scientific training nor university education, and spent his life first as a linen merchant and then a civil servant in a small Dutch city.

To understand quite how game-changing Leeuwenhoek’s discoveries were, you have to imagine a world where just about everyone on the planet could only see things that were within the range of unaided human eyesight. Magnifying glasses were the preserve of a privileged few, and other optical instruments, such as simple telescopes and microscopes, were rarer still. So it’s little wonder that Leeuwenhoek was met with disbelief when he claimed that he had seen bustling, vibrant lifeforms in what for everyone was just a drop of clear, pure water.

To find out how this extraordinarily curious Dutchman arrived at his discoveries, Rajan Datar is joined by Elisabeth Entjes who is one of the editors of Leeuwenhoek’s Collected Letters, Tiemen Cocquyt who as curator at the Boerhaave Museum of the history of science in Leiden has a special interest in Leeuwenhoek’s microscopes, and by biochemist and writer Nick Lane who is professor of Evolutionary Biochemistry at University College London.

Kafka's The Metamorphosis: A man turns into a monstrous bug Jul 11, 2019

A man wakes up in the body of a verminous insect – this is the plot of one of the most celebrated short stories of all time – Franz Kafka’s 1915 novella The Metamorphosis. Dealing with the isolation and absurdity of modern existence, it has fascinated readers all over the world in its openness to varying interpretations, and the way it questions the very norms of society as well as literary form.

Joining Rajan Datar to explore this most enigmatic work is Dr Carolin Duttlinger, the author of four books on Kafka and co-director of the Oxford Kafka research centre, Professor Alice Staskova, native of Kafka’s home city of Prague and specialist on Kafka and music, Dr Peter Zusi from the department of Czech Literature at University College London, and with the contribution of the Nigerian novelist Adrian Igoni Barrett who wrote his own take on The Metamorphosis – about a black man in Lagos who wakes up white.

Hugh Masekela: The iconic South African musician Jul 04, 2019

The story of Hugh Masekela’s life is intertwined with the history of South Africa itself. Born into a relatively privileged family in a mining town east of Johannesburg, Masekela was aware from an early age of the separatist and exploitative legacy of colonialism. As he grew up and discovered his love of music, it soon became clear to him that fulfilling his ambitions as a black musician would have to be done far away from the brutal apartheid government which had come to power in 1948.

In his adopted home in the United States, Masekela enjoyed a string of hit records and mixed with the great and the good of the jazz world. By now exiled from South Africa, he used his profile and his music to protest against repression and inequality, and wrote one of the defining songs of the campaign to free Nelson Mandela from prison.

In his musical ventures he brought musicians together from across the African continent, in a spirit of Pan-Africanism which was so important to him. When he eventually returned to South Africa after thirty years away, he continued to rally for causes close to his heart. Joining Bridget Kendall is jazz historian Dr Lindelwa Dalamba from Wits University in Johannesburg; jazz critic Gwen Ansell and author of Soweto Blues: Jazz, Popular Music, and Politics in South Africa; and the late musician’s nephew and former road manager, Mabusha Masekela.

James Watt: The power of steam Jun 27, 2019

In this 200th year since his death, we look at the life and work of James Watt, the Scottish innovator whose ground-breaking ideas helped power the Industrial Revolution and lay the basis for much of the mechanised world we take for granted now. He wasn't the inventor of the first steam engine - that had existed before his time - but his improved steam engine was vastly more efficient than earlier versions. As a result, industrial production rates soared and workplaces were transformed by new machines: changes that were to revolutionise society as well as industry. So who was James Watt? What inspired him and who helped him? Bridget Kendall talks to historians Dr. Malcolm Dick, Director of the Centre for West Midlands History at the University of Birmingham, and Professor Larry Stewart from the University of King's College in Halifax, Nova Scotia, who specialises in early modern science. She is also joined by curators Val Boa from The McLean Museum in Greenock, Scotland that houses an important James Watt collection, and Ben Russell, Curator of Mechanical Engineering at the Science Museum in London where he looks after a number of Watt-related objects, including his legendary attic workshop.

The Bhagavad Gita: A guide to spiritual wisdom Jun 20, 2019

The Bhagavad Gita didn't start life as an exclusively religious text but over the two thousand years since it was composed the verses have taken on many different layers of meaning. For millions of Hindus today, the Gita has a similar scriptural status to the Quran for Muslims or the Bible for Christians. In the 20th century, others have seen the Gita as a guide to management strategy, a tool for self-help and even a call to arms for Indian independence in the face of British colonial rule.

The story begins on a battlefield with the warrior Prince Arjuna suffering a breakdown. As warring families line up on opposing sides, Arjuna appeals to his charioteer Krishna for help in overcoming this existential crisis. In the 700 verses which follow, Krishna presents his friend with three options: the paths of action, knowledge and devotion.

Joining Bridget is Professor Chakravarthi Ram-Prasad from the University of Lancaster in the UK, Professor Angelika Malinar from the University of Zürich, Switzerland, and from the US Professor Richard Davis, the author of The Bhagavad Gita: A Biography.

Cnut: England's Viking king Jun 13, 2019

King Cnut the Great started life as a young Viking warrior, but quickly became one of the most successful kings in Anglo-Saxon history, reigning over a huge empire covering England, Denmark and Norway in the early 11th Century. For some, he was the perfect Christian king; for others, he was a ruthless warlord. Today in popular culture his name is associated with the tale of King Cnut and the waves - the legend of an arrogant king who believed he could stop the tide.

Joining Bridget Kendall to disentangle the facts from legends about King Cnut are Else Roesdahl, professor emerita of Medieval Archaeology at the University of Århus, Denmark; Eleanor Parker, lecturer in Medieval English Literature at Brasenose College, Oxford University, UK; and historian Timothy Bolton, author of the biography Cnut the Great.

How Afghanistan won its freedom from Britain Jun 06, 2019

The months between May and August 1919 were a crucial time for Afghanistan: it was the period of the Third Anglo-Afghan War followed by the declaration of Afghan independence from Britain. So how was modern Afghan national identity forged? Who were the leaders responsible? Why, in the 19th century, had the country become financially and politically dependent on Britain? And what, a century on, is the legacy Afghanistan's independence struggle?

These are some of the issues that Bridget Kendall discusses with historians of Afghanistan, professors Shah Mahmoud Hanifi, Sana Haroon and Benjamin Hopkins.

Rasputin: The Siberian mystic who charmed the Tsar May 30, 2019

Rasputin’s story is a familiar one – an illiterate Siberian peasant who managed to secure the confidence of the last Tsar and Tsarina of Russia, while indulging his legendary sexual appetite and love of hard drinking. Rasputin was so revered by his acolytes that they would collect his fingernail clippings, as if they were some kind of holy relic. When his extraordinary life was brought to an equally extraordinary end when he refused to die – murdered eventually in cold blood by a group of aristocrats – it unleashed the Russian revolution, and changed the geopolitical landscape in ways that still resonate today.

That’s one version of events that’s held sway for more than one hundred years. And yet so much of the Rasputin legend has been pieced together by those looking to discredit him. Is it possible to peel away the layers of myth-making and get to the heart of who Rasputin really was and what he stood for?

Joining Bridget Kendall on a truth-seeking mission is Russian imperial historian Helen Rappaport, author of The Race to Save the Romanovs; Russian literary translator and executive editor of the Los Angeles Review of Books, Boris Dralyuk; and historian Douglas Smith, author of the 2016 biography Rasputin: Faith, Power and the Twilight of the Romanovs.

The Moon from Earth May 23, 2019

For as long as humans have gazed up at the moon it has been an object of fascination. From the Aztecs to the Romans to the Romantics, the moon has inspired everything from artistic outpourings to religious devotion. So how has our understanding of our nearest cosmic companion changed over the millennia? And, 50 years on from the Apollo 11 Moon landing, how has our relationship with the moon been changed by our lunar explorations?

Rajan Datar talks to Monica Grady, Professor of Planetary and Space Sciences at the Open University in the UK; Anthony Aveni, Professor Emeritus of Astronomy, Anthropology, and Native American Studies at Colgate University in the US; and Alexandra Loske, a German art historian and co-author of Moon: Art, Science, Culture.

Pearls: Treasures of the sea May 16, 2019

Pearls are the most chameleon-like of jewels: they can sell for millions or for just a few dollars, they have been used to symbolize both chastity and debauchery, they have been conspicuously worn by men and women. The production methods of both cultured and natural pearls have been fraught with controversy and their position as fashion and status symbols has waxed and waned over the centuries. Bridget Kendall discovers the social history of pearls with jewellery historian Beatriz Chadour-Sampson and Pittsburgh University professor Molly Warsh. Plus jewellery writer Victoria Finlay puts to the test one of the more colourful claims about what is in essence an iridescent blob of nacre: that if you drop a pearl in a glass of vinegar it will quickly dissolve.

Thoreau: the writer who went to the woods May 09, 2019

Rajan Datar and guests explore the life and legacy of the American thinker Henry David Thoreau and his famous work 'Walden', which describes the young writer's experiment in living simply at Walden Pond in Massachusetts, for two years, two months and two days in the 1840s. A landmark text in American literature, ‘Walden’ has been enjoyed by generations for its insights into work and leisure, nature, solitude, society, the good life and more. Rajan and guests discuss this book and another of Thoreau’s famous works – the essay known as ‘Civil Disobedience’, read by some of the most influential figures of the twentieth century, such as Gandhi and Martin Luther King. They also reflect on the legacy of Thoreau’s work around the world today, in an age in which his themes – from protesting injustice to living the simple life – continue to resonate with readers. With expert guests Laura Dassow Walls, Kristen Case, John Kaag and Yoshiaki Furui. Produced by Alice Bloch.

Fado: Portuguese soul music May 02, 2019

In its 200-year lifetime the Portuguese song known as fado has been intertwined with the country's politics. At first it was an expression of the woes of Lisbon's underclass, which perhaps explains its predominantly melancholy character. In the early 20th century when a military coup brought the fascist regime of António Salazar to power, fado was accused of being degenerate music and government officials censored its lyrics. However, as the dictatorship's grip on the country tightened over a 50-year period, fado flourished, and the regime saw its potential as a tourism marketing tool.

When democracy was restored in the 1970s, fado began a decline because of its perceived links to the former far-right regime. As those associations have faded with time, fado is now enjoying a renaissance. The music's found favour with a new generation of singers who are taking this nostalgic, yearning song to a global audience.

Rajan Datar investigates the ups and downs of fado, its history, legends and mystique, with guests historian Rui Vieira Nery, ethnomusicologist Lila Ellen Gray and editor-in-chief of Songlines magazine, Simon Broughton.

Queen Njinga of Angola: Fearless fighter Apr 25, 2019

The 17th Century Queen Njinga was among the most successful of Africa's rulers in resisting European colonialism: she defied no fewer than 13 different Portuguese governors of modern-day Angola and ruled the kingdoms of Ndongo and Matamba for over three decades. She was no ordinary person, the warrior Queen. She was a fearless fighter, a military strategist, often ruthless, a shrewd diplomat and an inspirational leader in a period of huge turmoil, shifting alliances and conflict. Her name still resonates throughout the region and she stands as a symbol of the continent's fight against oppression. Rajan Datar is joined by professor Linda Heywood, author of the first comprehensive biography of Njinga in English, professor Roquinaldo Ferreira whose many publications include studies of the frequent social and cultural exchanges between Brazil and central Africa; and one of the leading experts on west African economic history Dr Toby Green.

Inside the mind of Leonardo da Vinci Apr 18, 2019

Leonardo da Vinci is best known for his paintings - creating masterpieces like the Mona Lisa and The Last Supper. But through his notes and drawings we know him also to have been a sculptor, mathematician, botanist, palaeontologist, anatomist, architect and engineer, recording insights and inventions that were astonishingly ahead of their time. So what do his observations and experiments tell us about his unique understanding of the visible world around him?

To mark the 500th anniversary of Leonardo's death Bridget Kendall talks to Martin Kemp, Emeritus Professor in the History of Art at Oxford University in the UK; Carmen C. Bambach, a curator at The Metropolitan Museum of Art, New York, in the US; and Prof Marina Wallace, a curator and art historian.

Chess: a chequered history Apr 11, 2019

It’s been called the 'gymnasium of the mind', both mental exercise and a way to build self-esteem. Born some 1,500 years ago, the game of chess was one of the world’s first strategy board games, though little is still known about its origins. Was it first conceived to teach Indian army generals? Or devised to turn a tyrannical King into a virtuous ruler? Or was it a meditative diversion for Japanese monks? It’s easy to forget that the modern game of chess is only 500 years old – and that other ancient forms of Chess, like Xiangqi in China and Shogi in Japan, are much older, still evolving and still played today.

Joining Bridget Kendall to explore the history of chess, are the chess historians Jean-Louis Cazaux and Rick Knowlton, the novelist Andrei Kurkov who’s followed the dramas of Russian chess through the ages, and the Grandmaster Jovanka Houska who’ll be challenging Bridget to a game of chess in the studio.

Twenty Thousand Leagues under the Seas Apr 04, 2019

It is an all-time adventure classic, a novel by Jules Verne that started life in serialized form 150 years ago and has gripped readers ever since, making it one of the most translated works in publishing history (and yes, the original French title says 'seas' in plural). It also made a household name out of its main character, Captain Nemo, the troubled and enigmatic commander who transports us through underwater wonders - including the lost world of Atlantis - in Nautilus, a submarine that itself is a technological marvel. So popular is the story, stars as famous as James Mason, Omar Sharif and Michael Caine have featured in movie versions. But there are dark undercurrents in the novel, themes of anger and revenge, as well as a number of enigmatic passages. To explore the long-lasting appeal of Twenty Thousand Leagues under the Seas, Rajan Datar is joined by Marie-Helene Huet, professor of French at Princeton University and MIT; French writer and translator Laurence Sudret, general secretary of the Société Jules Verne; Swiss-born author and engineer Jean-Michel Margot who had amassed one of the world's foremost collections of Verne materials; and Terry Harpold, Professor of English, Film and Media Studies at the University of Florida who specializes in science fiction.

Napoleon: From empire to exile Mar 28, 2019

The story of how an average-sized artillery officer from a small Mediterranean island came to dominate revolutionary France and become the international celebrity of his age is an extraordinary one. Born on Corsica in 1769, Napoleon Bonaparte appeared to avoid engaging with the military career for which he was destined. And yet within a decade, his ambition, ego and enormous talent for self-promotion propelled him to the rank of general and eventually the highest office in France.

At the beginning of the 19th century Napoleon’s rise appeared unstoppable. He was declared First Consul for life, then crowned himself Emperor of the French. He brought a period of much-needed stability to France and codified laws and systems which exist to this day. When his wife Joséphine was unable to give him a child, he divorced her and cemented an alliance with Austria’s imperial family. At its height, the Napoleonic empire stretched across most of Western Europe and numbered 40 million people. But his continuing thirst for power also sowed the seeds of his downfall.

Bridget Kendall delves into the life and legacy of one of history’s most divisive figures. With guests Rafe Blaufarb, Professor of History at Florida State University in the US; Kate Astbury, Professor of French Studies at the University of Warwick, UK and the co-curator of www.100days.eu ; and Professor Annie Jourdan from the University of Amsterdam, Holland.

The spice trade: Selling the scents of luxury Mar 21, 2019

The trade in spices goes back to ancient times: from the Frankincense trails that originated in the Dhofar Highlands in present day Yemen to the Queen of Sheba who travelled to Jerusalem with camels laden with spices. For centuries, spices have captured our imagination far more than any other commodities, and spice traders, from the Arab merchants to the European trading companies of the Age of Discovery, capitalised on the mystique of these luxurious aromatics to create a value chain that led to vast fortunes being made and Empires established. And this worldwide craze for spices played a great part in the rise of globalised trade and the birth of the Stock exchange and the capitalist system.

Joining Rajan Datar to discuss the Spice Trade is Professor Gary Paul Nabhan whose ancestors were Arab spice merchants and who’s the author of "Cumin, Camels, and Caravans: A Spice Odyssey", Dr Chris Nierstrasz, Lecturer in Global History at Erasmus University in Rotterdam and specialist on the United Dutch East India Company, and the TV Chef and Indian cookery writer Anjum Anand.

Moomin Creator Tove Jansson Mar 14, 2019

Tove Jansson was a Finnish-Swedish author and illustrator best known for her children's books about the Moomins.

These white, hippo-like characters live in the imaginary world of Moominvalley where they subtly challenge social norms and utter philosophical statements such as "I knew nothing, but I believed a lot."

While the Moomins brought Jansson worldwide fame in the 20th century, she was also a painter, an accomplished novelist and a political cartoonist who took risks poking fun at Hitler. Her work often mirrored her private life in which she defied stereotypes of the time by working and earning money for her family, travelling alone, and having relationships with both men and women.

Joining Rajan Datar to discuss the life and works of Tove Jansson are her niece, Sophia Jansson; Boel Westin - a professor of children's literature from Stockholm University and the author of the authorised biography of Tove's life called Life, Art, Words; and British children's author Philip Ardagh, author of The World of Moominvalley.

Plus Mayumi Tomihara - an expert on Tove Jansson from Tokyo's Sacred Heart University who has translated many of Tove's adult novels into Japanese.

First broadcast on the BBC World Service in March 2019.

Anaesthesia: Unwrapping oblivion Mar 07, 2019

Millions of us around the world have undergone an anaesthetic, putting our trust in specialists who keep us alive while surgeons carry out complex operations. Huge advances have been made in this field in the last 150 years, thanks to the work of pioneering doctors, dentists and scientists who often risked their own lives to advance the possibilities of surgery and make anaesthetics safe.

And yet in this twilight world of artificial sleep, there are many things experts still don’t understand about what is really happening in the brain and how our consciousness is affected. And what of the reports of patients waking during surgery? How credible are these stories and what can they tell us about memory, consciousness and human experience?

Calouste Gulbenkian: The architect of Middle East oil Mar 01, 2019

Today, the Istanbul-born Armenian financier Calouste Gulbenkian is mostly remembered as a great art collector and philanthropist; at his death in 1955 he was thought of as the world's richest man. But perhaps more than any of the above, he may have been the world's most tenacious negotiator: how else would he have held on - for decades - to the main source of his fabulous wealth, his minority share in major oil companies, despite their concerted effort to push him out? In the 150th year of Gulbenkian's birth, Rajan Datar follows Calouste's life and deal-making with his great grandson Martin Essayan; historian Dr. Jonathan Conlin, author of a new biography of Gulbenkian; and Professor of Business History Joost Jonker.

Robinson Crusoe: The man and his island Feb 21, 2019

The story of Robinson Crusoe and his many years of survival alone on a deserted island has enchanted the English-speaking world for centuries. Many people first come across the story as a children’s book or a film portrayal, celebrating Crusoe’s buccaneering adventures and his heroic efforts to tame his wild environment, create shelter and food supplies, and eventually befriend the indigenous man he calls Friday. But closer reading of Daniel Defoe’s original novel, written 300 years ago this spring, reveals a more complex tale of sin and redemption, debating fundamental questions about man’s place in the world against a backdrop of colonial expansion, transatlantic commerce and the slave trade.

Bridget Kendall talks to the Defoe scholar Professor Andreas Mueller from the University of Northern Colorado in the USA; Olivette Otele, Professor of History at Bath Spa University in the UK; and Karen O’Brien, Professor of English Literature at the University of Oxford in the UK.

Lu Xun: Writing the story of New China Feb 14, 2019

Lu Xun has been often been called the father of modern Chinese literature. His short stories about the misery and cruelty of ordinary life in China have been interpreted both as revolutionary political statements inspired by the May Fourth Movement of 1919 which wanted to sweep-away outdated social mores, and as a brilliant new take on ancient Chinese literary traditions. Some of his works, both fiction and non-fiction, have been required reading for Chinese schoolchildren since the communists took charge of education in the country. But - like his life - Lu Xun's work doesn't easily fit under any simple banner and reflects the turbulent, confusing and contradictory history of China in the first three decades of the 20th century.

Quentin Cooper talks to Professor Eileen Cheng, the author of acclaimed new translations of Lu Xun into English, Ohio State University Professor Kirk Denton, one of today's leading Lu Xun scholars, Professor Hu Ying from University of California who studies the culture of early 20th century China, and writer Yiyun Li. The reader is Paul Courtenay Hyu.

The talking drums of West Africa Feb 07, 2019

The Talking Drum is one of the most sacred instruments of West Africa. Shaped like an hourglass, the drum has a unique melodic sound which means it can imitate the tones of language and in this way speak words. Along with its spiritual power and healing properties, the talking drum is also a source of history, poetry and proverbs.

Bridget Kendall traces the story of the talking drum to the present day with Mohamed Gueye from Senegal, who descends from a hereditary drummer family, Richard Olatunde Baker who specialises in the talking drum of the Yoruba of Nigeria, the Ivorian-French poet and novelist Veronique Tadjo who focuses on the influence of the talking drum on African literature and the Senegalese-French social anthropologist Dr Hélène Neveu Kringelbach.

The Top of the World Jan 31, 2019

The North Pole lies at the very top of our world. Covered in a thick layer of sea ice, this uninhabitable frozen point in the Arctic Sea has fascinated us for centuries as both a physical location on a map and as a far away place in our imagination. Warmer than the South Pole, the northernmost point of the Earth’s axis sits outside of any time zone in a place where the sun rises and sets just once a year. Today, it has come to symbolise a warming planet but remains linked to exploration and mythology.

Joining Bridget Kendall to discuss the North Pole are the explorer, author and former climate scientist Felicity Aston MBE; Klaus Dodds, Professor of Geopolitics at Royal Holloway, University of London, and author of the forthcoming book The Arctic: What Everyone Needs to Know; and Michael Bravo, Senior Lecturer at the University of Cambridge, Head of Circumpolar History and Public Policy Research at the Scott Polar Research Institute and author of a new book called North Pole.

The Heel and the Sneaker Jan 24, 2019

What’s in a shoe - apart from a foot? Shoes can be so much more than a protection and ‘dressing’ of our feet: from Egyptian pharaohs to European paupers, footwear has been linked not just with the wearer’s social and economic standing but also cultural identity, personality and even moral values.

Rajan Datar follows the history of footwear with the help of Elizabeth Semmelhack, Senior Curator of the Bata Shoe Museum in Toronto; Giorgio Riello, Professor of Global History and Culture at the University of Warwick; sports shoe historian Thomas Turner; and footwear researcher at the KASK School of Arts in Gent, Catherine Willems.

Goya: Seeking truth through art Jan 17, 2019

The 18th Century Spanish artist Francisco José de Goya y Lucientes has been called the “most radical artist that ever lived”. He was not afraid to shock with his depictions of the darkest sides of human nature, and his work still shocks us today. Goya rose from humble beginnings to become the official court painter to the kings of Spain. But while he created dazzling portraits of royals and aristocrats, his personal vision was filled with madmen, witches, beggars, and fantastical creatures of the night. His years in the Spanish court coincided with one of the most turbulent times in the country’s history, and his graphic images of war and suffering reveal a compulsion to make art that changed the way we think about the world.

Bridget Kendall discusses Goya’s life and works with Mark Roglán, Director of the Meadows Museum at Southern Methodist University in Dallas, Texas, in the US; Janis Tomlinson, Director of Special Collections and Museums at the University of Delaware in the US; And Xavier Bray, Director of the Wallace Collection in London, UK.

Antigone: A drama of defiance Jan 10, 2019

The play Antigone by the Greek playwright Sophocles was written almost 2,500 years ago, but to this day it is believed to be the most performed play- anywhere in the world. It tells the story of Antigone, a girl who ends up challenging the power of the ruler of Thebes, in a devastating battle of wills that pits family duty against the law of the state. So why does this story of civil disobedience still speak to people, and how was it originally received by its very first audience in Ancient Athens in the 5th century BCE? Joining Rajan Datar to discuss Antigone and its later modern interpretations are the acclaimed actor, director and former Greek Culture Minister Lydia Koniordou, the theatre director Olivier Py who staged Antigone with male prisoners at this year’s Avignon Theatre Festival in France, the Syrian playwright Mohammad Al Attar who’s the author of a new adaptation of Antigone about Syrian women refugees, and Dr Rosie Wyles, Lecturer in Classical History at the University of Kent, and author of “Costume in Greek Tragedy”.

The Master and Margarita: Devilish satire Jan 03, 2019

The Master and Margarita by Mikhail Bulgakov, which tells the fantastical story of a visit of the devil to the Soviet Union, is considered to be one of the most successful Russian novels of the 20th Century. Written in secret in the 1930s when Stalinist repression of the arts was at its height, the novel was only published more than 25 years later, when its blend of biting satire and magic realism created a sensation, not just in Russia but also in the West, inspiring rock bands like The Rolling Stones.

This programme explores the novel and its cultural influence, and also asks how it reflects Bulgakov’s often traumatic experience as a writer in Stalinist Russia. Joining Bridget Kendall are Julie Curtis, the biographer of Mikhail Bulgakov, and professor of Russian literature at Oxford University, Peter Mansilla-Cruz, the director of the Bulgakov museum in Moscow, Edythe Haber, associate of the Davis Centre at Harvard University and professor emerita at University of Massachusetts, Boston, and Dr Olga Voronina from SSEES, University College, London, who have both published widely on Bulgakov’s writings.

Fermentation: Ancient Food Alchemy Dec 27, 2018

Whether it’s kimchi, kombucha, kefir or kraut, fermented foods are today all the rage. And yet people have been fermenting food and beverages for thousands of years – to preserve food stuffs, to break down toxins, to mark rituals and to enhance flavour.

Without knowledge of the science, local communities practised fermentation instinctively, through trial and error and by careful observation. In the 18th and 19th centuries, scientists argued over why foods fermented as they did. Many believed in the theory of ‘spontaneous generation’. But it was not until the discoveries of Louis Pasteur that the micro-organisms at work in food which bring about fermentation began to be understood. Ironically, Pasteur’s research led to a widespread preoccupation with killing the very bacteria that aid fermentation – combined with the growth of food production on an industrial scale.

More recently, fermented food and drink has been marketed for its health benefits, with claims it can enhance the bacteria in our intestinal tracts, boost our immune systems and even lower the risk of contracting some serious diseases.

Rajan Datar attempts to separate fact from fiction, with the help of three experts: the American fermentation revivalist Sandor Katz, Danish microbiologist Dennis Sandris Nielsen and the chef and food writer Olia Hercules, who’ll be demonstrating how to make a simple fermented recipe.

The Emergence of Modern Turkey Dec 20, 2018

100 years ago, Turkish defeat in World War One signalled the end of the once great Ottoman Empire. What emerged was a European orientated secular republic led by a man who used social engineering to shape Turkey in his own image – Mustafa Kemal Atatürk. Bridget Kendall examines this key period of Turkish history and asks whether modernisation could have been brought in less forcefully, and why the women who were helping bring about similarly progressive ideas were eventually side-lined. And what impact did Ataturk’s social revolution have on the arts and literature? Joining Bridget is Recep Boztemur, Professor of History at the Middle Eastern Technical University in Ankara, Dr Hülya Adak from Sabanci university in Istanbul, who specialises in gender and nationalism, and the actor, theatre director and playwright Yeşim Özsoy, whose latest play examines Turkish identity from 1918 onwards.

Aleksandr Solzhenitsyn: Revealing the Gulag Dec 13, 2018

The Russian author Aleksandr Solzhenitsyn was a towering literary figure whose novels, chronicles and essays have lifted the lid on the horrors of the Soviet gulag network, which over several decades incarcerated millions of often innocent prisoners. Born a hundred years ago, Solzhenitsyn survived the brutal conditions of a gulag in Kazakhstan and it was this harrowing experience that provided the impetus for his best-known works, starting with his novella, One Day in the Life of Ivan Denisovich and culminating in The Gulag Archipelago, a multi-volume history of the Soviet forced labour camps from 1918 to 1956.

Bridget Kendall is joined by two Solzhenitsyn scholars: Professor Daniel Mahoney from Assumption College in the United States and Dr. Elisa Kriza from Bamberg University; and by Professor Leona Toker of Hebrew University in Jerusalem, an expert on labour camp literature.

The Iranian Coup of 1953: Overthrow of a Prime Minister Dec 06, 2018

In 1953 Iran’s democratically elected Prime Minister Mohammad Mossadeq was overthrown in a coup. It was billed as a popular uprising in support of Shah Mohammad Reza Pahlavi, yet behind the scenes were the British and American intelligence services. Mossadeq had swept to power only two years earlier promising to nationalise Iran’s vast oil reserves, but this, along with an apparent Communist threat, worried the two western governments whose post-war economies relied heavily on access to Iranian oil. Rajan Datar discusses the coup with Iran scholar Ervand Abrahamian, professor of modern Iranian history at St Andrews University Ali Ansari and journalist and author Azadeh Moaveni.

Diaghilev and the ballet revolution Nov 29, 2018

The Russian dance impresario Sergei Diaghilev transformed not only ballet, but all the arts in the 20th century. His ground-breaking Ballets Russes burst onto the scene in Paris in 1909 and replaced stuffy set pieces with shockingly vibrant performances that brought together scenery by artists Picasso and Matisse, costumes by Coco Chanel, avant-garde music by Stravinsky and Prokofiev, and a new style of movement from innovative dancers such as Nijinsky. The Ballet Russes became the world’s leading dance company for nearly quarter of a century, and its creative impulse still influences dance, music and art today.

Bridget Kendall explores Diaghilev and the Ballets Russes with Lynn Garafola, Professor of Dance at Barnard College, Columbia University in the US; Jane Pritchard, Curator of Dance at the Victoria and Albert Museum in London; and the French dance writer Laura Cappelle.

Charlie Chaplin Nov 22, 2018

For many people, Charlie Chaplin and the Tramp, a character he created at the start of his film career, are synonymous. This funny little man with a black moustache and a waddling gait, dressed in baggy trousers and a tight jacket, with oversized shoes and a small bowler hat, made millions of people laugh, turned Chaplin into a household name and - in his day - the highest paid entertainer in the world. But there was more to Chaplin than just a virtuoso physical comedian: he was a versatile actor, writer, musician and director. He carefully fine-tuned every aspect of his feature films, no matter how long it took or what the cost, making him - possibly - the only complete auteur in film history. He had an eye to posterity: even in the early days when films were thought of as disposable, he carefully preserved all his works. And he also had business acumen: with his brother Sydney he masterminded brilliant publicity campaigns, re-releases and lucrative deals. Bridget Kendall is joined by silent film historians Ellen Cheshire, Donna Kornhaber and Paul Duncan to explore Chaplin's world: the films that made him famous, the people who helped him become a star, and the hidden depths and contradictions behind the slapstick humour.

Coal: a Burning Legacy Nov 15, 2018

Coal is a commodity that’s often been considered dirty, old fashioned and cheap, a humble black stone that evokes images of soot covered workers. And yet this lump of energy became the essential fuel for industrialisation all over the world, transforming societies and launching empires. But this transformative power came at a cost, as well as bringing unprecedented wealth it also brought unprecedented pollution. So how are countries dealing with coal’s legacy, and will dependence on coal carry on into the future?

Joining Rajan Datar is Dr Kenneth Mathu from Gibs, University of Pretoria in Johannesburg; Dr Shellen Xiao Wu, specialist on China and author of “Empires of Coal”; the American environmental lawyer Barbara Freese who’s written “Coal: A human history”, and Darran Cowd, the manager of Kent Mining museum in South East England.

Lifting the lid: The history of the toilet Nov 08, 2018

Toilets come in many shapes and sizes around the world: squat and throne, dry and flush, indoor and outdoor. Most of us use one every day, but over two billion people still do not have access to facilities, leading to health and sanitary problems and even risks for personal security.

From the 50 seater public toilets of ancient Rome and the modern flush toilet, invented by a godson of a 16th century British monarch, this feat of human engineering is believed to date back 5000 years to the Indus Valley Civilisation. In recent years it’s become a battleground for equality, but in a world of increasing water shortages, could the flush toilet become a thing of the past?

Joining Bridget Kendall to discuss the history of the toilet are Ann Koloski-Ostrow - an archaeologist specialising in Roman toilets from Brandeis University in the United States; Barbara Penner - a Professor of Architectural Humanities from University College London and the author of books on public toilets and the modern bathroom; and Dr Bindeswar Pathak - a sociologist, social activist, and Founder of the Sulabh Sanitation and Social Reform Movement. He is also the inventor of an environmentally friendly compost toilet that’s used widely around India today.

Calm in the chaos: The story of the Stoics Nov 01, 2018

Stoicism is a school of thought over two thousand years old that asked how to live "a good life" in an unpredictable world, and how to make the best of what is in our power, while accepting the rest as it happens naturally. It trumpeted the value of reason as man's most valuable Virtue, and offered a practical guide to remaining steadfast, strong and in control.

This ancient Graeco-Roman philosophy had a broad influence that reached across time and disciplines: its Virtues inspired some of the same from Christianity in the Middle Ages, its belief in Reason spoke to the works of 18th Century German philosopher Immanuel Kant, and the relationship it drew between judgement and emotion went on to inspire the modern Cognitive Behavioural Therapy Movement.

Bridget Kendall discusses this philosophy's key ideas and evolution, and explores what it is to live like a Stoic in the modern world with guests Massimo Pigliucci, Nancy Sherman and Donald Robertson.

Cambodia's ancient Khmer Empire Oct 27, 2018

Around the twelfth and thirteenth century CE Angkor was thought to be one of the world's biggest cities. Its massive temple complex at Angkor Wat covered hundreds of acres adorned with majestic towers, terraces and waterways: symbols of the might of the Khmer kings who ruled the region. Angkor Wat attracts millions of tourists every year and has pride of place on the Cambodian national flag but there's much more to Angkor and the Khmer civilisation than its temples. Bridget Kendall talks about Khmer history with David Chandler, Emeritus Professor of history at Monash University in Melbourne; architectural historian Dr. Swati Chemburkar from the Jnanapravaha Arts Centre in Mumbai; anthropologist Dr. Kyle Latinis from the Institute of Southeast Asian Studies in Singapore and former Dean of the University of Cambodia; and art historian Dr. Peter Sharrock from the School of Oriental and African Studies in London.

Who was the real Cleopatra? Oct 20, 2018

The myths that have grown up around Cleopatra since her eventful reign in the first century BCE are so vivid and alluring that they seem to have taken on a life of their own. The Egyptian queen has been portrayed in art and literature as a wily temptress whose devastating beauty seduced two of Rome’s most powerful men, or as a ruthless killer who murdered her own relatives to get ahead, or as a tragic lover who took her own life using the bite from a poisonous snake. But how much of this is actually based on historical fact? There is evidence that Queen Cleopatra was in fact a clever stateswoman and scholar, who spoke multiple languages and successfully governed Egypt for over 20 years, becoming one of the most powerful female rulers in the ancient world.

Bridget Kendall unpicks fact from fiction with Joyce Tyldesley, reader in Egyptology at the University of Manchester; Maria Wyke, professor of Latin at University College, London; and Christian Greco, director of the Museo Egizio (Egyptian Museum) in Turin, Italy.

Karl Kraus: Austria’s fearless satirist Oct 13, 2018

The Austrian satirical writer Karl Kraus used his forensic pen to expose the Hapsburg Empire and 20th century Vienna for its dishonesty and decay. He was the master of the punchy one liner, as well as being extremely prolific: his magazine Die Fackel ran to 922 editions, that's some 22 thousand pages, and Kraus wrote most of them. He was also full of contradictions: he could be both progressive and reactionary, sometimes profound and sometimes petty, and while he was born into affluence he remained concerned by other people's poverty. Many of his contradictions could be equally applied to the cultural world of Vienna itself in this period of turmoil and transition. And this makes Kraus - the journalist, poet, playwright, actor, lecturer and acerbic aphorist - a uniquely scathing and illuminating guide to this important historical epoch and the city at its heart.

Rajan Datar talks about Kraus with Dr. Katharina Prager from the Ludwig Boltzmann Institute for History and Society, Dr. Simon Ganahl from the Austrian Academy of Sciences, both in Vienna, and Germanist Dr. Ari Linden from the University of Kansas.

Cool: Sunglasses, style and American counter-culture Oct 06, 2018

We probably know ‘cool’ when we see it, but what lies behind it and where did it originate?

Most scholars agree that cool is a mode of being, an attitude or aesthetic. Some argue it arose out of a West African mode of performance, and was later developed in jazz circles by African-American musicians. Cool served to hide one’s emotions and survive confrontation with any hostile external forces – namely racism. In post-World War Two America, cool took on a new meaning, especially when its ideas were translated to white popular culture. It symbolised an individual’s rebellion, and new icons of cool emerged (especially on the silver screen) onto which people projected their deepest desires and fears.

Today cool is a commodity, taken up by global brands and in some ways divorced from its rebellious roots. Bridget Kendall is joined by three cultural historians to explore the multiple meanings and emergence of cool, including Joel Dinerstein from Tulane University in New Orleans, US, Claudia Springer from Framingham State University in Massachusetts, and Carol Tulloch from Chelsea College of Arts in London.

Frida Kahlo: A life in colour Sep 29, 2018

Frida Kahlo, the iconic and flamboyant Mexican painter, is one of the most famous female artists of our age. Her rebellious and subversive works are instantly recognisable. Many are self-portraits depicting an arresting dark and heavy-browed woman, often in bright traditional Mexican dress with flowers woven into her hair, staring straight out of the canvas.

In her life time, she was better known as the wife of her celebrated artist husband, Diego Rivera. Now, she is arguably more famous than him, and her paintings sell for millions of dollars. Having lived and documented a life filled with physical and emotional pain, her blisteringly personal and political accounts now speak to populations young and old the world over. Bridget Kendall discusses her life, work and posthumous success with Kahlo experts Circe Henestrosa, Gannit Ankori, and Oriana Baddeley.

The Jet Engine Sep 22, 2018

Quentin Cooper and guests follow the twists and turns of jet engine development: from its 1930s origins and the often highly dangerous early fighters in World War 2, through Korea, Vietnam and the Cold War, to the much more reliable modern incarnations which now take us all over the world. Just three decades after the first airplane took off, the emerging aero industry was already stalling. There were limits to how big propeller-driven aircraft could get. How fast they could go. And how far. For the air age to truly take off it needed a new kind of propulsion: the jet engine. With Professor of the History of Industry and Technology at Rutgers University Philip Scranton; historian Hermione Giffard, author of Making Jet Engines in World War II; and former head of the Aircraft Collection at the Deutsches Museum in Munich Walter Rathjen.

Edgar Allan Poe: Master of horror Sep 15, 2018

Edgar Allan Poe is a 19th century American writer whose spine-chilling gothic tales have inspired generations of horror and mystery fiction writers. His poem ‘The Raven’, and short stories such as ‘The Fall of the House of Usher’ and ‘The Pit and the Pendulum’ brought him international fame, and he is also thought to have invented the detective fiction genre with ‘The Murders in the Rue Morgue’. But his tumultuous life was beset by personal tragedy, poverty and artistic struggle which seemed to echo many of the dark themes in his work.

Bridget Kendall explores Poe’s life and extraordinary work with J. Gerald Kennedy, Boyd Professor of English at Louisiana State University; Diane Roberts, Professor of English and Creative Writing at Florida State University; and Paul Collins, Professor of English at Portland State University.

The Making of Modern Japan Sep 08, 2018

In the mid-19th century Japan transformed itself from feudal state to economic powerhouse at breakneck speed. Taking their cue from Western imperial powers, the rebel samurai who seized power in 1868 implemented an astonishing programme of reform.

By removing an entire ruling elite, introducing national conscription and compulsory education, the Meiji rulers set about building a brand new society. Even the measurement of time was changed, which led to considerable confusion between generations.

Rajan Datar and guests will unpack the origins of this dynamic transformation, and examine how it led Japan to a period of drastic imperial expansion and the subsequent atrocities of World War II.

Joining Rajan will be historians Naoko Shimazu from Yale NUS College in Singapore, Mark Ravina from Emory University in Atlanta, USA, and Barak Kushner from the University of Cambridge in the UK.

The American author James Baldwin Sep 01, 2018

Born in 1924, the prolific writer and thinker James Baldwin is a landmark figure in twentieth century American culture. The author of popular novels such as Go Tell It on the Mountain and bold essay collections such as The Fire Next Time, his works explored themes including race, sexuality, identity, democracy and love. An African-American man born in Harlem who spent much of his life in France, he became an important literary voice during his country’s civil rights movement. A critic and analyst of his country’s racial divide, he saw division as destructive and urged his fellow citizens to achieve a better future together.

Rajan Datar and guests reflect on some of the key moments in James Baldwin’s life and work. With expert scholars Rich Blint, Ernest L. Gibson III and Magdalena Zaborowska.

The Acropolis: Cradle of democracy Aug 25, 2018

The Acropolis of Athens, with its crowning glory the Parthenon and its massive marble pillars, is one of the most recognisable sites in the world.

In the 5th and 6th century BCE, it was where the concept of democracy – rule by the people – first developed, where modern- day theatre was born, and it gave the West the foundation of its politics, philosophy and history.

But the Acropolis is also, like our humanity, a place of constant struggle and contradiction, from the pride and ambition of the ancient Athenians that led to its destruction, to its current status as a symbol of the Greek state.

Joining Rajan Datar to look at the history and meaning of the Acropolis is Paul Cartledge, Emeritus Professor of Greek culture at the University of Cambridge and author of Democracy: A Life; Dr Andronike Makres, co-Director of the Hellenic Education and Research in Athens, and Demetrios Papageorgiou, Professor of Applied Mathematics at Imperial College London.

Friedrich Engels: The Man Behind Karl Marx Aug 18, 2018

A champagne-loving industrialist who enjoyed hunting, a literary critic and an upstanding Victorian gentleman: this does not sound like a description of your typical advocate of proletarian revolution or the co-author of the Communist Manifesto. Yet Friedrich Engels was all those things and more. Deliberately keeping in the shadows of his comrade-in-arms Karl Marx, Engels led an eventful life, fighting in the 1848 German revolution, attending secret meetings with Chartists and keeping two homes in Manchester: a respectable one that fitted his image of a bachelor businessman, the other a boarding house where he lived with his working-class lover Mary Burns and her sister, and future wife, Lizzie. Rajan Datar charts the life and work of Friedrich Engels with the help of leading scholars of Marxism: Jonathan Sperber from the University of Missouri, Terrell Carver from Bristol University, Belinda Webb-Blofeld from Kingston University and Christian Krell from the Friedrich Ebert Foundation.

Empress Nur Jahan: Leader of the Mughals Aug 11, 2018

Empress Nur Jahan was the most powerful woman in 17th century India, wielding an unparalleled control over the Mughal Empire. Born as Mehr-un-Nissa, she came from a wealthy Iranian family who came to India and made their way up the imperial court. After the death of her first husband, a Persian soldier, she became the twentieth and final wife of Mughal Emperor Jahangir and her rise to the top really began. Often sitting beside her husband in court, she controlled trade routes, designed gardens and mausoleums, was said to be a skilled hunter and was the only Mughal Empress to have coins minted in her own name.

Joining Rajan Datar to explore the life of Empress Nur Jahan is Ruby Lal, professor of South Asian Studies at Emory University and author of 'Empress: The Astonishing Reign of Nur Jahan'; Mehreen Chida-Razvi, Research Associate in the Department of Art History at SOAS, University of London; and Shivangini Tandon, Assistant Professor at the Department of Women's Studies, Aligarh Muslim University, India.

Waiting for Godot: The play that changed the rules of theatre Aug 04, 2018

Waiting for Godot is a play by the Irish writer Samuel Beckett that revolutionised 20th century theatre when it was first performed more than 60 years ago. Often referred to as a play in which nothing happens, it is about two characters who spend their time waiting for a mysterious person called Godot who never appears. Today it is one of the world's most important and best- known plays and has become a comment on our political and social climate, as its themes of hope and despair have led to it being re-interpreted in a number of conflict situations around the world, from South Africa to Sarajevo.

Joining Rajan Datar is the South African theatre director Benjy Francis who was the first to stage Waiting for Godot with an all-black cast in Apartheid South Africa in 1976, the Irish theatre director Garry Hynes whose current production of Waiting for Godot is at the Edinburgh International Festival, and Professor of theatre at Reading University, Anna McMullan, who is also co-Director of the Beckett International Foundation.

Christina of Sweden: Queen of surprises Jul 28, 2018

An accomplished young horsewoman who loved fencing and male attire, the 17th-century Swedish Queen Christina was anything but a conventional princess. And she kept springing surprises on her court and country: after just a decade on the throne she abdicated, converted to Catholicism and moved to Rome. Once there, she put herself forward as a candidate for the post of queen of Naples, opened a public theatre and scandalised the Holy See by a liaison with a cardinal. Bridget Kendall follows Christina's adventures with biographer Veronica Buckley, and historians Stefano Fogelberg Rota and Therese Sjovoll.

Vincent van Gogh: The struggling artist Jul 21, 2018

The Dutch post-Impressionist painter Vincent van Gogh is one of the most influential painters in western art. His series of still life sunflowers are known around the world today, but during his lifetime in the 1800s he lived in poverty, selling incredibly little of his work, some say just one painting, and suffered several serious breakdowns. One of his most famous paintings - The Starry Night - is said to be the view from his room in a French psychiatric hospital where he’d admitted himself shortly after severing his own left ear. This programme looks at the man behind these iconic paintings, explores how and why he became a painter and picks apart the various theories around his death from a gunshot wound at the age of just 37.

Joining Bridget Kendall to discuss van Gogh’s life and work are Louis van Tilborgh, Senior Researcher at the Van Gogh Museum in Amsterdam and Professor of Art History at the University of Amsterdam, van Gogh biographer and co-author of van Gogh: The Life, Steven Naifeh, and British art historian Lucrezia Walker.

Mark Twain: The 'father of American literature' Jul 14, 2018

Mark Twain, born Samuel Langhorne Clemens, was known for his piercing wit, irreverent satire and social commentary. Leaving school early following the death of his father, he lived many lives in one: spending time as a journalist, steamboat pilot and world traveller, suffering significant personal and financial losses. These are just some of the experiences that would feed into his novels, articles, short stories, essays and the thousands of letters that are still being unearthed today.

Best known for his book Adventures of Huckleberry Finn, which tells the story of a rebellious young boy called Huck floating down the Mississippi River with a runaway slave called Jim, Twain developed a style that led to him being credited as "the father of American literature". The work, like so much of Twain's other writing, tackles serious social issues and continues to be shrouded in controversy to this day.

Bridget Kendall discusses his life and works with Twain scholars Shelley Fisher Fiskin, Thomas Smith, Jocelyn Chadwick and Mark Dawidziak.

Pioneers of surgical hygiene Jul 07, 2018

The Hungarian obstetrician Ignaz Semmelweis, born 200 years ago this month, saved the lives of hundreds, possibly thousands, of new mothers with his forward-looking ideas about hospital hygiene. He insisted that junior doctors working for him wash their hands in chlorinated lime solution before examining expectant mothers. This simple procedure reduced mortality by something like 90 per cent at the Vienna maternity ward that he was in charge of. Many more deaths could have been prevented had other physicians followed his advice without delay. So why did many in the medical profession resist not just Semmelweis's findings but also similar ideas of his fellow hygiene pioneers, such as Joseph Lister? Quentin Cooper discusses the beginnings of surgical cleanliness with Dr. Sonia Horn from Vienna University, Dr. Andrew Cunningham from Cambridge University and Prof. Michael Worboys from the University of Manchester.

The invention of numbers Jun 30, 2018

Try and imagine a world without numbers. Telling people how many siblings you have, counting your wages or organising to meet a friend at a certain time would all be much more difficult. If you’re reading this on a digital screen, even these words are produced through a series of zero and one symbols. We take them so much for granted yet some cultures don’t count and some languages don’t have the words or symbols for numbers. This programme looks at when and why humans first started start to count, where the symbols many of us use today originate from and when concepts like zero and infinity came about.

Joining Bridget Kendall to explore the history of numbers and counting are anthropological linguist Caleb Everett from the University of Miami, writer and historian of mathematics Tomoko Kitagawa, and Emeritus Professor of Mathematics at Warwick University in the UK, Ian Stewart.

The life and works of William Blake Jun 23, 2018

William Blake is now one of England’s best-loved poets and artists, associated with the well-known poem “The Tyger” and the hymn “Jerusalem”, regularly coined England’s unofficial national anthem. But in his time he was an eighteenth century radical visionary who challenged the social order as well as political and religious orthodoxy at every turn. He was even tried for sedition.

Rajan Datar discusses his life, works and remarkable legacy with Blake experts Dr. Linda Freedman, Dr. Susan Matthews, Prof. Jason Whittaker and artist Michael Phillips.

J. William Fulbright: Scholarships and Soft Power Jun 16, 2018

In many countries, the word 'Fulbrighter' has become almost synonymous with US-sponsored scholarships. But what about the man whose idea it was to set up this international scholar exchange programme over 70 years ago: how did J. William Fulbright convince his fellow Senators to support this novel concept? After all, the aims of the programme were nothing if not ambitious: "the achievement in international affairs of a regime more civilized, rational and humane than the empty system of power of the past".

To discuss the history of the Fulbright programme, Bridget Kendall is joined by Fulbright's biographer Randall Woods, Professor of History at the University of Arkansas; Joan Dassin, Professor of International Education and Development at Brandeis University in Massachusetts; and two recent Fulbright scholarship recipients: language teaching specialist Vitoria Prochet from Brazil and human rights activist from Afghanistan Nilofar Sakhi.

The tales of Timbuktu Jun 09, 2018

The fabled city of Timbuktu is a curiosity. To 16th century Muslim scholars, it was the cosmopolitan hub of Islamic learning in West Africa; to European explorers 300 years later, it was a place of mystery, whose name remains synonymous with being at the end of the Earth. Most recently, in 2013, Timbuktu was at the centre of the world's attention again, after Islamist militants threatened thousands of valuable historic manuscripts stored in the city's famous libraries. Believed to be the richest person in history, it was Mansa Musa - the emperor of the vast Mali Empire - who first developed the desert settlement into a place of intellectual debate in the 1300s. The golden age of Islamic learning he began still survives today.

Joining Bridget Kendall to discuss the importance of Timbuktu in Islamic history are Dr. Gus Casely-Hayford, director of the Smithsonian National Museum of African Art in Washington, D.C., who has recently published a Ladybird Expert book about the city; Dr. Susana Molins-Lliteras, a researcher at the Tombouctou Manuscripts Project and postdoctoral fellow at the Department of Historical Studies, University of Cape Town; and Dr. Lansiné Kaba, Professor of History and Thomas M. Kerr Distinguished Career Professor at Carnegie Mellon University in Qatar.

The piano: Hitting the right keys Jun 02, 2018

What’s the secret to the 300 year-old success of the piano, an instrument that was hardly a huge hit when it was invented around the turn of the 18th century?

Perhaps it’s the ability of the instrument to convey a vast range of styles from singing melodies to percussive rhythms, and from classical music to jazz, rock and pop. With the help of musical examples, Bridget Kendall and guests will explore how the piano has inspired music from composers on every continent.

Joining Bridget will be the historic keyboard specialist Dr Elena Vorotko from the Royal Academy of Music in London, pianist and author Professor Kenneth Hamilton from the University of Cardiff, and the writer Stuart Isacoff in New York.

Simone de Beauvoir: Feminist thinker for modern times May 26, 2018

Simone de Beauvoir was a French philosopher and writer whose work exploring what it is to be a woman shaped feminist thinking today. A pioneering intellectual, she used her existential ideas around freedom and responsibility to shape her life, literature and politics. Rajan Datar discusses her life and work with writers Claudine Monteil and Lisa Appignanesi, and philosopher Tove Pettersen.

Catherine the Great of Russia May 19, 2018

Famous for her lovers and satirised for her colourful personal life, Catherine the Great was in many ways one of Russia’s most progressive and moderate rulers, modernising 18th century Russia, improving educational standards and creating a flourishing arts and literature scene. But she also turned Russia into the biggest Empire on earth since the Roman Empire, which included the annexation of Crimea. So how far has her imperial mind set influenced Russia’s modern rulers, like President Putin?

Joining Bridget Kendall to discuss the life and legacy of Catherine II of Russia, is Professor Andrei Zorin, cultural historian and Chair of Russian at the University of Oxford, Simon Dixon, Professor of Russian History at University College London and author of the biography “Catherine the Great”’ and Dr Viktoria Ivleva, who specialises in Catherine’s role as a woman ruler and her use of uniform and costume.

Material World: Making the Modern Factory May 12, 2018

Bridget Kendall and guests discuss the key components of the global story of the factory, tracing its development from eighteenth century Britain to twenty-first century China and beyond. Exploring how the factory came to shape not just the material world but entire social worlds too, they share their expert knowledge on topics such as the lives of factory workers, the capitalist and communist factory, and the changing face of manufacturing in an age of robots and smart technology.

Bridget is joined by Joshua B. Freeman, Martin Krzywdzinski, Alessandra Mezzadri and Nina Rappaport. The sociologist Ching Kwan Lee also shares her insights into factory life in Shenzhen as it transformed in the late twentieth century.

Machu Picchu: The secrets of a forgotten city May 05, 2018

The ancient Inca town Machu Picchu is now the most visited tourist attraction in Peru - and yet it lay nearly forgotten for over three centuries until American and Peruvian explorers drew the world's attention to it in the 1910s. And despite a century of excavations at the site, there are still many unanswered questions about Machu Picchu: why was it built in the first place, who were the immigrants that made up a large proportion of the town's population and why was it abandoned so quickly.

To find out more about Machu Picchu, Bridget Kendall is joined by leading archaeologists of the Inca civilisation Lucy Salazar and Michael Malpass, the celebrated mountaineer and explorer Johan Reinhard and by writer Mark Adams who retraced the steps of the 1911 expedition led by Hiram Bingham that put Machu Picchu back on the map.

Plastic: How it Changed the World Apr 28, 2018

The birth of modern plastic began in 1907 with the invention of Bakelite, one of the first plastics to be made from entirely synthetic components. But plastic in a particular form was being used many thousands of years ago by the Olmec, the earliest known civilisation in Mexico, who played with balls made of a natural polymer - rubber.

Over the years the plastics industry has grown from the work of a handful of inventors to a global player whose products reach into almost every corner of our lives. Plastic has been at the heart of one of the most important changes in virtually all societies since the second world war: the consumer revolution. But while it is a force for good in many areas and a highly versatile material that appears in the most surprising places, plastic today is a major environmental preoccupation. Can we modify our use towards this wonder material, or can scientists rise to the challenge of creating a plastic that will break down completely when it has reached the end of its useful life?

Rajan Datar is joined by nanoscientist Professor Ajay Mishra, chemist Professor Andrea Sella and journalist Susan Freinkel to explore the story of plastic.

Sugar: A Sweet Menace Apr 21, 2018

Rarely has one foodstuff had such global influence as Sugar – on our trade and economy, movement of people around the world, and health and treatment of fellow humans. Once a costly luxury called “white gold”, it was pivotal in one of mankind’s most shameful chapters – slavery. Joining Rajan Datar to find out more about Sugar and its connection with power is the Canadian historian Dr Elizabeth Abbott, the writer Marina Budhos whose Indian background inspired her research, and the Columbian political scientist Dr Eduardo Gomez, author of ‘Geopolitics in Health’.

What is Zoroastrianism? Apr 14, 2018

It is a religion that has lasted three millennia, claims to be the world's first monotheistic creed and to have influenced major faiths such as Christianity, Judaism and Islam, inspired artists from Voltaire to Freddie Mercury but Zoroastrianism may be heading for extinction: in some communities only children of male Zoroastrians are admitted to the faith and there are probably fewer than 200 thousand left now.

Rajan Datar talks about the history of Zoroastrianism with Dr. Sarah Stewart, Shapoorji Pallonji Lecturer in Zoroastrianism at SOAS, University of London, Malcolm Deboo, President of the Zoroastrian Trust Funds of Europe, the oldest Zoroastrian organisation on the continent, and Yuhan Vevaina, professor of Sasanian Studies at Oxford University.

Votes for Women: the Global Story Apr 10, 2018

It was exactly a hundred years ago that women in the UK won the right to vote: though at first it was only for property owning women over thirty. But Britain wasn’t the trail blazer. Seven countries were ahead of it including two of its colonies. So what were the deciding factors? Was it the changing circumstances created by wars and the collapse of Empires? Or was it the suffragettes’ sometimes violent tactics? And why did Switzerland take as long as 1971 to enfranchise women? Joining Bridget Kendall to look at the global story of how women got the vote is the Indian social scientist Nikita Sud, Jad Adams the author of “Women and the Vote”, and Lindie Naughton the biographer of the first woman elected to the British parliament Constance Markievicz.

From Straw Poll to Opinion Poll Mar 30, 2018

Today, we can’t imagine an election without an opinion poll gauging public opinion on who’s leading, who’s won a debate or who’s more popular with a specific group of voters. Even our favourite chocolate bars and footballers are subject to a poll. But how did straw polls evolve into the scientific number crunching we know now? What is their purpose and impact? How differently are they used around the world? And just how reliable are they?

Bridget Kendall is joined by economist and chairman of Gallup Pakistan Dr Ijaz Shafi Gilani; Scott Keeter, senior survey advisor for the Pew Research Center in Washington; and Sir John Curtice from the University of Strathclyde.

Lawrence of Arabia Mar 24, 2018

T.E Lawrence was a British scholar and adventurer whose involvement with the Arab Revolt during the World War One inspired one of the most celebrated films in cinema history. So how did a man who was offered a knighthood and became an international celebrity end his days in near obscurity? Bridget Kendall is joined by historians James Barr and Juliette Desplat, and writer Scott Anderson to discuss his life and legacy.

Yves Saint Laurent: Fashion revolutionary Mar 17, 2018

In the ten years since his death, the impact of designer Yves Saint Laurent on women’s fashion remains undimmed. The pea coat, the trench, the trouser suit – many of his designs are now staples of the modern Western woman’s wardrobe. So how did this famously shy and retiring man achieve global success? And did his fashion innovations for women shape social change in the 1960s, or were they a response to his times?

Bridget Kendall looks back at Saint Laurent’s life and legacy with director of the Yves Saint Laurent Museum, Olivier Flaviano, fashion historian Emilie Hammen and one of Saint Laurent’s last assistants, designer Charles Sébline.

Herman Melville: Moby Dick Mar 10, 2018

Moby Dick is the story of a crazed and vengeful sailor, Captain Ahab, hunting a giant whale that bit off his leg. It's a large and challenging book and its author, Herman Melville died without knowing how influential or revered it would become. Although it failed to impress when it first came out in 1851, it’s now hailed as a ‘great American novel’, one of the towering achievements of American literature. With Bridget Kendall to explore the book and its author, Professor Jamie Jones from the University of Illinois, Emily Ogden from the University of Virginia and poet and academic from Lancaster University in the UK, Paul Farley.

The original Goths Mar 03, 2018

The Goths were a Germanic tribe infamous for their brief sack of Rome in 410 AD, but their cultural and political influence was felt throughout Europe for centuries. They re-shaped the Balkans, preserved the Roman way of life in Italy, and presided over a cultural flourishing in Spain. But how, many centuries after their demise, did they come to give their name to an important architectural style in medieval Europe and, in the 20th century, to a subculture popular all over the world?

Bridget Kendall talks all things Gothic with David Gwynn, historian at Royal Holloway, University of London, and author of Goths, the Lost Civilisation. Also on the panel are Janina Ramirez, a cultural historian, broadcaster and author who focuses on the Middle Ages, based at the University of Oxford, and Mischa Meier, professor of ancient history at the University of Tubingen in Germany.

Dante’s Inferno: The poetry of Hell Feb 24, 2018

Inferno is the 14th century epic that tells the story of Dante Alighieri’s imaginary journey through the underworld. It is the first part of Dante’s The Divine Comedy, and is widely considered to be one of the world’s greatest poems. “Abandon all hope you who enter here” is the famous phrase inscribed on the gates of Dante’s Inferno, and Hell is divided into nine circles, with cruel and unusual punishments afflicting the sinners, who range from the lustful and cowardly in the upper circles to the malicious at the bottom of Hell. Joining Rajan Datar to explore Dante’s Inferno is Dr Vittorio Montemaggi, author of Reading Dante’s Commedia as Theology; Claire Honess, Professor of Italian studies at the University of Leeds, and Sangjin Park, Professor of Italian at Busan University of Foreign studies in South Korea, who will be speaking about the role Inferno played in shaping Korea’s national identity.

Magellan: First Man Round the Globe? Feb 17, 2018

Portuguese sailor and explorer Ferdinand Magellan set out 500 years ago to find a route to the riches of the spice islands, north east of present day Indonesia. Through a series of adventures and tragedies, Magellan’s voyage discovered the Straits of Magellan joining the Atlantic and Pacific oceans through Southern America and was the first expedition to completely circumnavigate the World. But Magellan died on the way and the remaining crew were in fact first round the globe. To explore an achievement that changed the World and still influences us today, Bridget Kendall is joined by Dr Rodrigo Cacho, Dr Alison Sandman and Dr Rachel Winchcombe.

The Little Prince: Lessons from an aviator’s life Feb 10, 2018

‘It is only with the heart that one can see clearly; what is essential is invisible to the eye.’ Words of advice from a wily desert fox to a little boy who fell to Earth from an asteroid. That quote, by the French author and pilot Antoine Saint-Exupery, is one of the most memorable passages from The Little Prince, a slim volume that is one of the most frequently translated books of all time and has achieved this in just 75 years since its first publication.

But who was Saint-Exupery? How did he come to write The Little Prince? And what else do we know about this adventurer and romantic who risked his life as a pilot many times and captivated the world with his writing?

Bridget Kendall is joined by Olivier d'Agay, great-nephew of the writer and Director of the Antoine de Saint-Exupery Estate and Youth Foundation, Stacy Schiff, Pulitzer-prize winning author of an acclaimed biography of Saint-Exupery, and Bernard Chabbert, pilot and historian of French aviation.

Chinua Achebe: Rewriting the African story Feb 03, 2018

The Nigerian writer Chinua Achebe is regarded as a giant of world literature. Best known as the author of the ground-breaking novel Things Fall Apart, he was also acclaimed for his works of non-fiction, poetry and his books for children. Raised and educated when his country was still under British colonial rule, Achebe witnessed great change, experiencing both the dawn of an independent Nigeria and the devastation of civil war. He is a writer famed for depicting, in English, the traditions of Igbo society in south-eastern Nigeria, and for engaging with subjects such as conflict, corruption and colonialism.

In this programme, Rajan Datar and guests reflect on the life and legacy of this academic, author and advocate of African fiction. Featuring scholars Louisa Egbunike, Ernest Emenyonu and Terri Ochiagha.

Boudica: Warrior queen Jan 29, 2018

Boudica, also known as Boadicea, was a member of Iron Age aristocracy in Roman-occupied England, and her husband was the ruler of the Iceni people. When he died in around 60AD, Boudica, driven by Roman brutality, led a rebellion against the Roman army and marched on London. It was a ferocious attack that nearly drove the Romans out of Britain before Boudica was finally defeated. Today, she is an iconic and sometimes controversial figure.

To explore Boudica, Bridget Kendall is joined by Professors Richard Hingley and Miranda Aldhouse-Green and Dr Jane Webster.

The alphabet of chemistry Jan 20, 2018

The Russian chemist Dmitri Mendeleev attempted nothing less than to pull apart the fabric of reality and expose the hidden patterns that lie beneath everything in existence, from shoes and ships and sealing wax to cabbages and kings. The result was something known to almost everyone who has ever been to school: the Periodic Table of the elements. But why this particular arrangement? And why is it still the foundation of chemistry?

Kubla Khan: A vision in a dream Jan 13, 2018

“In Xanadu did Kubla Khan a stately pleasure dome decree … “ - Kubla Khan by Samuel Taylor Coleridge is one of the most famous poems in the English Language. But it is also one of the strangest. It was composed during an opium dream, it remains unfinished and according to one theory, was implicated in a war in South Africa. And what is its relation to the real life Kublai Khan, the 13th century Mongol emperor who conquered China?

Joining Rajan Datar to discuss this mysterious poem is Coleridge’s award winning biographer Richard Holmes, the poet and senior lecturer in English Dr Peter Anderson from Cape Town University in South Africa, Professor Samantha Harvey from Boise State University in the US, and the Chinese historian Professor Kent Deng from the London School of Economics.

Flamenco: Darkness and light Dec 30, 2017

Flamenco is easily recognised across the world thanks to certain stereotypes, namely spotty dresses, shirt-tearing and lots of foot stamping.

The reality however is far more nuanced, and this extraordinarily complex music and dance form can take many years – if not a lifetime – to master. For those steeped in its traditions, they describe it as a way of life.

With the help of musical examples, Rajan Datar and guests explore how flamenco works, and discuss how it’s grown from its origins in the marginalised communities of southern Spain to become a commercial success the world over.

Joining Rajan are flamenco aficionado and guitarist Brook Zern, dancer María Bermúdez from flamenco’s heartland in Jerez de la Frontera and Dr Matthew Machin-Autenrieth from the University of Cambridge in the UK.

Sankara: Africa’s Revolutionary President Dec 23, 2017

Thomas Sankara is the revolutionary who became the first president of Burkina Faso in West Africa, and gave the country its name, meaning 'the land of upright people'. In his short time as leader of Burkina Faso, Sankara instituted sweeping reforms to make the country more self-sufficient and society more equal. For some Sankara was a hero, for others, he was a ruthless autocrat. This year marks 30 years after his mysterious -and as yet unsolved- assassination, but why do memories of him still haunt Africa to this day?

Joining Bridget Kendall to discuss Thomas Sankara, are Dr Amber Murrey-Ndewa from the American University in Cairo, Lamine Konkobo BBC Afrique journalist from Burkina Faso, and Aziz Fall, Professor of International Studies in Canada and campaigner for justice on behalf of the Sankara family.

Cotton: a Yarn with a Twist Dec 16, 2017

It is a fibre and a fabric that is part of many people's daily lives, it grows wild on at least three continents, it has been woven into cloth and traded all over the world for thousands of years. And when machines made possible the mass production of cotton, its story became entwined with the history of human slavery: making fortunes for a few, and condemning many to a life of misery. So what are the milestones in the history of cotton? And why has it always proved such a popular clothing material across the centuries and across the world?

Bridget Kendall is joined by four textile historians to trace cotton's origins and its evolution into one of the world's most important global commodities: Sven Beckert, Professor of History at Harvard, Prasannan Parthasarathi, Professor of History at Boston College, Giorgio Riello, Professor of Global History and Culture at the University of Warwick and the President of the Textile Society Mary Schoeser.

Stanislavsky: Founder of modern acting Dec 02, 2017

It was at the Moscow Art Theatre from the 1890’s onwards that Stanislavsky developed an innovative acting system that demanded actors really inhabit the role they are playing. This then inspired Method acting, which originated in the United States, and whose disciples range from Marlon Brando to Marilyn Monroe to the majority of big stars around the world today - some of whom have taken the system to an alarming extreme. This programme explores Stanislavsky's life and legacy, and also asks if his work has a role outside the theatre. Joining Bridget Kendall are Maria Shevtsova, Professor of Drama at Goldsmiths University of London, the Russian theatre historian Dr Arkady Ostrovsky, and the actor and director Bella Merlin.

Up close with tango Jul 15, 2017

Tango is easy to recognise: those daring steps, the tight hold of the dancing partners, the intense yet melancholy music dominated by the plaintive sounds of the bandoneon. But if you ask what exactly tango is and where it came from, the answer may not be so immediately clear - because it's more than a genre of music, more than just a style of dance. To get insights into the roots, the culture and even the magic of tango, Rajan Datar is joined by leading tango historians Maria Susana Azzi, Christine Denniston and John Turci-Escobar.

Silk Routes: Two Thousand Years of Trading Jul 01, 2017

China, Iran, Afghanistan, Syria, Uzbekistan and India: if you went to any of these places a thousand years ago, you would find goods and produce from the others. But how did they get there and why? This week’s Forum explores the ancient pattern of trading networks which criss-crossed the plains, deserts and mountains of China, Central Asia and points further West, and which encouraged not just the exchange of commodities like silk, paper and horses but ideas and people too.

Indian Princely States Jun 27, 2017

At the time of the Partition of India 70 years ago this year, there were more than 500 Princely States. These were states nominally ruled by Indian Princes but ultimately under the control of the British colonial powers. Many of these princes - male and female members of the Royal Family - had kingdoms dating back to the 8th and 9th Centuries. But after the British curbed their powers, was their role largely ceremonial or did they have a deeper impact on the Indian people? And how did these Princes survive after Partition? Joining Rajan Datar is the writer and historian William Dalrymple, the director of the King’s College London India institute Sunil Khilnani, and the Indian social scientist Nikita Sud from Oxford University.

How the metre changed the world May 01, 2017

Nowdays, if you want to find out how long one metre is, you can use a tape measure or, if you are a scientist, you can calculate the distance that light travels in a vacuum in 1/299 792 458 seconds. But how did we decide on what length a metre should be in the first place?

To follow the far-from-straight story of the metre Quentin Cooper is joined by Professor Robert Crease, historian of science at Stonybrook University in the USA; Professor Marc Himbert, Scientific director of the Metrology Laboratory at CNAM in Paris; and Dr. Jahnavi Phalkey, historian of contemporary and twentieth century science and technology at King’s College in London.

The Belle Epoque: A Golden Age? Apr 17, 2017

The Moulin Rouge in Paris is the risqué cabaret venue that encapsulates for many the 'Belle Epoque', a period of French and especially Parisian history around the turn of the 19th Century, where permissiveness mixed with political, commercial and creative optimism and when an extraordinary vitality and innovation seemed almost boundless. To explore the Belle Epoque, Dr Janina Ramirez is in Paris with the director of Le Petit Palais art gallery and museum Christophe Leribault, the associate artistic director of the Moulin Rouge, Janet Pharaoh, and professor of French history from Leeds University in the UK, Diana Holmes.

Machiavelli - Master of Power Apr 10, 2017

Over five hundred years ago, dismissed diplomat Niccolò Machiavelli produced his most famous work, ‘The Prince’. Written on the fringes of the Italian city of Florence, the book has long been read as a priceless guide to power and what holding it truly involves. But who was the man behind the work? Why did he claim that a leader must be prepared to act immorally? And why did the name of this one-time political insider become a byword for cunning and sinister strategy?

Rajan Datar explores the life and impact of Machiavelli’s ‘The Prince’, with writer and scholar Erica Benner, historian Professor Quentin Skinner and journalist David Ignatius.

Haile Selassie: The last Emperor of Ethiopia Apr 03, 2017

Emperor Haile Selassie was the last in the line of Ethiopia’s ancient monarchy. During his long rule he was revered as an international statesman and reformer, demonised as a dictator, and even worshipped as a God incarnate by the Rastafarians of Jamaica. He was without doubt a controversial figure, but achieved a status in the global arena previously unheard of for an African ruler.

Bridget Kendall discusses Haile Selassie’s life and legacy with Prince Asfa-Wossen Asserate, political analyst and author of ‘King of Kings: The Triumph and Tragedy of Emperor Haile Selassie I of Ethiopia’, who is also the great-nephew of Haile Selassie; Gerard Prunier, Independent Consultant on Eastern and Central African affairs, and former Director of the French Centre for Ethiopian Studies in Addis-Ababa; and Laura Hammond, an anthropologist specialising in Ethiopia at the School of Oriental and African Studies, University of London.

Yellow fever: Man against mosquito Feb 27, 2017

Outbreaks of yellow fever, such as the notorious 1878 'American plague' which swept through Memphis, Tennessee, used to kill thousands in a matter of weeks. So why was it so devastating? How did we manage to tame it in some parts of the world? And why does yellow fever still present a danger today for nearly a billion people living in tropical parts of Latin America and Africa?

Bridget Kendall discusses the history and the future of yellow fever with American writer and journalist Molly Crosby, author of The American Plague;

history professor from the University of Virginia, Christian McMillen who has a special interest in past and present epidemics;

and Dr. Nick Beeching who teaches clinical infectious diseases at the Liverpool School of Tropical Medicine.

The real story of Frankenstein Feb 20, 2017

In the nearly 200 years since Mary Shelley wrote Frankenstein, the story has taken on a life of its own. But the original tale is much more psychologically complex than the horror film versions suggest – a disturbing and thought-provoking parable that roots itself in the basic human need for love.

Bridget Kendall discusses the book’s origins, themes and continuing legacy with two scholars of English literature - Prof Karen O’Brien from Oxford University in the UK and Jessica Tiffin from the University of Cape Town in South Africa, and with the novelist and radio dramatist Jonathan Barnes.

Goethe: The story of colour Jan 30, 2017

The German polymath Johann Wolfgang von Goethe considered his monumental book known in English as The Theory of Colours to be his greatest achievement. The book is a record of hundreds of Goethe's observations about the way colour affects our mood, as well as a long and heated polemic with Isaac Newton's colour theory. Goethe's understanding of light and colour was scientifically flawed yet his book had a surprisingly strong influence on the fine and applied arts. To find out why, Bridget Kendall talks to art historian Alexandra Loske, colour writer Victoria Finlay and designer Odette Steele.

Alexandra Loske is an art historian who teaches at the University of Sussex, Curator at the Royal Pavilion and Brighton Museums, editor of the book Languages of Colour and author of Palette (forthcoming);

Victoria Finlay is a writer, former arts editor of the South China Morning Post and the author of Colour, Travels through the Paintbox and The Brilliant History of Color in Art;

Odette Steele is a Zambian textile designer recent and a graduate from the London College of Fashion at the University of the Arts, London.

Mata Hari: Dancer, lover, spy Jan 23, 2017

It is 100 years since the exotic dancer and legendary ‘femme fatale’ Mata Hari was executed by a French firing squad for passing secrets to the Germans during World War One. She was described at the time as the ‘greatest woman spy of the century’. But many now see Mata Hari as a convenient scapegoat, condemned merely for her unconventional lifestyle.

Bridget Kendall discusses the myths and realities surrounding women in espionage with Julie Wheelwright, programme director of non-fiction writing at City, University of London, and author of The Fatal Lover: Mata Hari and the Myth of Women in Espionage; Tammy Proctor, Professor of History at Utah State University and author of Female Intelligence: Women and Espionage in the First World War; and Hanneke Boonstra, a Dutch journalist who is writing an official blog about Mata Hari as part of this year’s centenary commemorations in the Netherlands.

The Silicon Chip: A Tech Revolution Jan 16, 2017

It’s forty five years since the commercial introduction of the first microcomputer chip set which evolved into the modern microprocessor, changing computers from tools for scientists into the engines which power today’s electronic consumer appliances. So how did the silicon chip evolve and where might this revolution be heading next? Bridget Kendal is joined by four distinguished computer and internet pioneers who helped spearhead some of the most important inventions of the computer age. Vinod Dham invented the first Pentium micro-processor and went on to become Vice-President at the world’s largest chip maker-Intel. His early work in this field earned him the nickname “The Father of the Pentium chip.” Sophie Wilson’s computer design was used to build the Acorn Micro-Computer. She also led the development of the ARM microprocessor, found in over half of the world’s consumer electronics. David Laws is a technology historian and a curator of the Computer History Museum in California. Dame Wendy Hall is a Professor of Computer Science at the University of Southampton in the UK. She worked alongside Sir Tim Berners Lee on an early version of the World Wide Web.

Utopia: Mr More’s Wondrous Islands Dec 21, 2016

Thomas More’s Utopia, published 500 years ago this month, is full of radical ideas and has provided food for thought to generations of people trying to find new ways to organise society. On his fictitious island More created a vivid mosaic of places, people and their customs and they have proven to be an inspiration not just for philosophers and politicians but also for writers. To mark the anniversary, BBC World Service and PEN International have asked three young authors, Rebecca F. John, Jose Pablo Salas and Lea Sauer, to take Utopia as a starting point for a new short story. Mr. More’s Wondrous Islands also includes a couple of intriguing passages from the original book. It is introduced by Jack Stewart, the readers are John Dougall, Bettrys Jones, Martina Laird and William Marquez and the producer is Radek Bosketty.

Thomas More's Utopia Dec 19, 2016

Five-hundred years ago, in what is now the Belgian city of Leuven, Thomas More published his vision for an ideal society which he called Utopia.To mark the anniversary, The Forum travels to Leuven University to debate More's book, its place in history and the politics it inspired.

Presenter Bridget Kendall is joined by Leuven University rector Rik Torfs, culture studies professor Fátima Vieira who leads the Utopia 500 Project, historian of communism professor Erik van Ree from Amsterdam University, and Dilar Dirik, an expert on the Syrian-Kurdish ‘utopia’ of Rojava.

Winner or Cheat? Doping in Sport Dec 12, 2016

A battle is raging over the future of sport. Advances in retrospective testing have seen champions stripped of their medals years after they stood on the podium. Allegations of state-sponsored doping in Russia have rocked the sports world and new treatments such as gene-doping are constantly evolving. The drugs change but the questions remain the same – how effective and how dangerous are performance-enhancing drugs? How do doping competitors evade the testers? And can sports tarnished by doping ever be cleaned up?

Sharing their knowledge with Bridget Kendall are four sport insiders: David Howman stepped down as Director of the World Anti-Doping Agency in 2016 after twelve years battling drug-taking in sport. David Millar is a British cyclist and former World Champion who has won stages at the Tour de France and rode in the professional peloton for over a decade. Banned for doping, he returned to the sport as an anti-drugs campaigner. He is the author of the memoirs ‘Racing Through The Dark’ and ‘ The Racer: Life on the Road as a Pro-Cyclist’. Professor Mario Thevis is a chemist who has tested competitors at seven Olympic Games and is Director of the Centre for Preventive Doping Research in Cologne, Germany. Dr Zhouxiang Lu has researched allegations of doping in China in the 1980s and 90s. He teaches at the National University of Ireland, Maynooth.

Drones and their Impact on the World Nov 14, 2016

Drones have been hailed as the most important technological development in aviation since the invention of the jet engine. They have changed the nature of modern warfare and they are also catalysing developments in fields as diverse as law enforcement, film production, disaster management, news gathering and agriculture. The availability and prevalence of drones in everyday life is increasing and creating enormous challenges in the fields of ethics, law and regulation – not least managing the flight paths of a potentially enormous number of small planes.

Bridget Kendall explores the history, present and future of drones. She is joined by Marke "Hoot" Gibson, the Federal Aviation Administration’s senior adviser on Unmanned Aerial Systems Integration; Sarah Kreps, associate professor of Government at Cornell University in the US; Michael Nautu who designs and builds drones for purposes ranging from agriculture and aerial mapping to “next-generation conservation” in Namibia.

The new curators: Who decides what’s culturally important? Nov 01, 2016

Some of us live in an age of super abundance – more things are being made and more information and goods are offered online than ever before.

Yet the internet also means that we no longer have to leave our selections to other people. If we want, we can sift through options to make our own choices, personalise our preferences, and even enlist the help of machine recommendations to highlight what we might like.

So in this brave new world, what is the role of a curator? Indeed, what does curation actually mean? With Bridget Kendall to explore the role of the modern curator, digital publisher Michael Bhaskar, the artistic director of the Serpentine Gallery in London, Hans Ulrich Obrist and Tasneem Zakaria Mehta, the director of one of India’s most iconic museums, the Dr. Bhau Daji Lad Mumbai City Museum in Mumbai.

Do we Need Artificial Intelligence? Oct 24, 2016

Look out of the window and you won’t see many robots – but the AI revolution is here. The relentless encroachment of machine-thinking into every aspect of our lives is transforming the way we think and act. Machine-learning algorithms drive our smartphones and social media - and they are increasingly present in our homes, offices, schools and hospitals. Whether driving cars, diagnosing disease or marking essays, artificial intelligence is everywhere. But how does machine-thinking compare to human thought and what are the limitations of AI? From biased training data to impenetrable black-box algorithms, Quentin Cooper and guests explore the strengths and limitations of AI.

To discuss whether we need AI are - Zoubin Ghahramani, professor of Information Engineering at the University of Cambridge and deputy director of the Leverhulme Centre for the Future of Intelligence; Lydia Nicholas, senior researcher at the British innovation foundation Nesta; Professor Kentaro Toyama of the University of Michigan, co-founder of Microsoft Research India and author of Geek Heresy: Rescuing Social Change from the Cult of Technology.

Concrete: Foundation of the modern world Oct 17, 2016

It has been around since before 6,000BC, the Ancient Egyptians used a version of it and so did the Romans. Nowadays it is the most common man-made building material in the world, used for some of the planet's biggest engineering projects - and some of the smallest. It has not always been loved by the public but architects and designers see both practicality and beauty. There is also an environmental issue - the production of concrete has a major environmental impact. So what of its future? Bridget Kendall explores concrete with architect Anupama Kundoo, design critic and writer Stephen Bayley and engineer and scientist professor Paulo Monteiro.

Why Are We Generous? Oct 10, 2016

Generosity feels like a good idea - most of us enjoy being generous from time to time and having people be generous to us. But what drives our altruistic tendencies?

From local volunteering to big philanthropic donations, from small acts of kindness to major sacrifices, what does this sort of behaviour say about us as human beings?

Do we really give without expecting something in return, or is there always some element of self- interest?

Joining Bridget Kendall to explore how and why we are generous are evolutionary anthropologist David Sloan Wilson, philosopher Judith Lichtenberg and experimental psychologist Patricia Lockwood.

What is the Best Way to Deal with Anxiety? Aug 22, 2016

Anxiety is a universal human emotion that has been described as the price-tag on freedom. It is the price we pay for a brain that can anticipate the future. But when anxiety spirals out of control it can take over our lives as we battle against phobias, panic attacks, dread and debilitating fear. So how is anxiety triggered and constructed in the brain? Is the almond-shaped amygdala the seat of fear or are our anxieties constructed in other parts of the brain? And for those made miserable by anxiety, how best can it be treated?

Bridget Kendall explores the biology of anxiety and some unexpected approaches to treatment, including friendship benches and therapy horses. She is joined by Joseph LeDoux, author of Anxiety and professor of Neuroscience and director of the Emotional Brain Institute, New York University; Dr Dixon Chibanda, a consultant Psychiatrist in Zimbabwe and pioneer of the Friendship Bench; Susanna Forrest, a British authority on the horse and author of The Age of Horse: An Equine Journey through Human History.

Image overload: Coping with the modern world's visual clutter Aug 15, 2016

Our lives are increasingly cluttered by images, not just in the world around us, but on advertising bill-boards, television screens, and even on our mobile phones. So how are we to process this barrage of information and make sense of the visual world?

How can today’s designers help us and how are we to avoid image-overload? Bridget Kendall talks to three people who help us navigate the increasingly crowded world of visual imagery: Alan Kitching, one of the world’s foremost practitioners of letterpress typographic design and printmaking, Aowen Jin, a Chinese-born artist who leads museum tours in the dark and Roma Agrawal, a structural engineer who spent six years designing London’s skyscraper The Shard.

Balloons and How they Changed the World Aug 08, 2016

A small toy balloon floating free into the sky. A giant hot air balloon filled with passengers peering down at the ground. Classic images, but what about the huge balloons now being developed to help us explore outer space? Or the tiny balloons which bio engineers inflate inside your body to help blood surge through your veins? Or the extraordinary balloonomania that spread across Northern Europe in the late 18th century? Bridget Kendall explores the colourful history of the balloon and its even more intriguing future with guests:

Sharing and Why it is Essential for the Human Race Aug 01, 2016

Everyone likes to be alone sometimes, but we also all spend much of our lives collaborating and sharing things with others. Many argue that on this increasingly crowded planet, we need to master the art of sharing much better if we are to survive and flourish. So what makes us want to share new ideas and pass on our experience?

Bridget Kendall discusses three very kinds of sharing - digital information, genes and national infrastructure. She is joined by Jonah Berger, marketing professor at the Wharton School at the University of Pennsylvania in the United States; Connie Jeffery, assistant professor of Biological Sciences and head of the Jeffery Lab at the University of Illinois in Chicago; Dr Elham Ibrahim, commissioner for Infrastructure and Energy for the African Union in Addis Ababa, Ethiopia.

Radioactivity: Friend or Foe? Jul 11, 2016

One of the first things that comes to mind when thinking of radioactivity is often a nuclear accident or dangerous rays. But radioactivity is in fact a much more varied phenomenon, one that can bring us great benefits as well as put us in danger. With help from three experts, Rajan Datar looks for a more nuanced picture of the role radioactivity plays in our lives.

Unfinished: The Art of the Incomplete Jun 20, 2016

We are at The Metropolitan Museum of Art in New York at The Met Breuer, where the exhibition "Unfinished: Thoughts Left Visible", is a springboard to explore the notion of things unfinished or incomplete. The concept of a work of art that is unfinished, the so called 'non finito' style, has been with us since the Renaissance. But it has taken on new meaning in modern art of the 20th and 21st Century. So how should we respond to a work which is unfinished whether it is a painting, a book, a piece of music, a film or a building? And, how does the idea of ‘unfinished’ translate into an ever-changing historical and political context?

Presenter Bridget Kendall is joined by Andrea Bayer, Jayne Wrightsman, Curator in The Met’s Department of European Paintings and co-curator of "Unfinished: Thoughts Left Visible" at The Met Breuer; Negin Farsad, a celebrated stand-up comedian, actor and film-maker of Iranian heritage; Kerry James Marshall, the internationally renowned American artist whose work will be the subject of a major exhibition at The Met Breuer this October 2016; Andrew Solomon, professor of Clinical Psychology at Columbia University in New York, and an award-winning writer who is also president of PEN American Center.

After Dark: How we Respond to Darkness May 23, 2016

Dr Janina Ramirez explores our relationship with, and attitudes to, darkness and the night. From the beginning of humanity when night was a time to sleep and hide from predators, over millennia the night and darkness has gathered a multitude of myths and cultural references all around the world and is something we can exploit, or something we might fear. Dr Janina Ramirez examines the human perspective of the dark, from night vision technology to Norwegian forest myths.

Dr Ravindra Athale, of the Office of Naval Research in Arlington USA, an expert on night vision technology, who examines how nocturnal animals help high tech, and how our ability to see at night has affected the way we use the dark to conceal and surprise.

Rules and how they govern us May 02, 2016

We all need rules - nature has them and we impose them on our communities in order to function; sometimes fairly and sometimes not- depending on your perspective. But just how important are rules and how do rules in nature affect our function as human beings? And how are our rules being used and interpreted by machines as artificial intelligence and deep learning evolve at enormous speed?

Bridget Kendall discusses rules in nature, rules in society and rules in robotics and AI with Sean B. Carroll, professor of molecular biology, genetics, and medical genetics at the University of Wisconsin–Madison, whose new book The Serengeti Rules: The Quest to Discover How Life Works and Why it Matters, explores regulation in the natural world- from every molecule in our bodies to the number of animals and plants in the wild. Dr Nina Power, a philosopher interested in protest who explores when and why we break the rules. And, Dr Jason Millar an engineer and philosopher who explores the ethics of robotics- how we apply human rules to machines and how they might begin to interpret those rules independently.

Balance: How we Find Equilibrium Apr 25, 2016

Balance is essential. It stops us falling over or getting too cross and it stops machines failing catastrophically. There are also very fine balances present, more generally in nature and across the universe. But much of the World is not in exact and perpetual balance - it needs constant fine tuning.

To help explore our latest understanding of balance in human beings, machines and music, Bridget Kendall talks to Patricia Kopatchinskaja, the distinguished Moldovan-Austrian violinist, who explores the internal balance need to play world class music; Jade Kindar-Martin, high wire artist and member of the Flying Wallendas who examines the fine tuning of mind and body needed to keep in balance on a high wire; Professor Andrew Heyes, head of Department of Mechanical and Aerospace Engineering at the University of Strathclyde, in Scotland who looks at the very fine balances needed to ensure machines work effectively and safely.

Lost and Found Apr 16, 2016

From the horrors of human suffering and plunder of ancient artefacts in war to the reshaping of musical traditions, we examine the notion of things lost and found.

British journalist Julian Borger reflects on the unmasking of some of the most notorious Balkan war criminals, Iraqi archaeologist Dr Lamia al-Gailani Werr mourns the loss of ancient relics in modern conflict and American pianist Bruce Brubaker deconstructs modern minimalist music.

A Single World, Many Identities? Apr 11, 2016

Bestselling Turkish novelist Elif Shafak, Nick Bostrom from Oxford’s Future of Humanity Institute and Ann Phoenix from UCL's Institute of Education trace the evolution of 21st century identity with the BBC’s Jo Fidgen. Are technology and geopolitics conspiring to create a new type of human, unrecognisable to our forebears? Is ‘serial migration’ the new norm for transnational families and what effect is this having on the identity of the young? Or perhaps we should drop the concept of Identity altogether?

Living at the Edge: Life in Extreme Environments Apr 06, 2016

Bridget Kendall explores extreme living and what it tells us, from human exploration to deep sea fish and synthetic biology. Bridget and her guests explore hot dry deserts and sub-zero polar ice, deep sea vents, salt heavy lakes, acid hot springs and outer space. NASA scientist Lynn Rothschild is a pioneer in the field of astrobiology, interested in probing the limits of life on earth, to better understand where we might find life signs elsewhere in the universe. Oliver Crimmen is the Fish Curator at the Natural History Museum in London. He’s an expert on how some sea creatures can survive both freezing and hot water – and several miles beneath the surface of our oceans. And explorer Rosie Stancer takes her own body to the edge – with solo trips to both the South Pole and the Arctic North, and a new expedition planned across China’s largest desert.

Taming Nature Mar 30, 2016

Is the idea of a pristine landscape an illusion, given that over thousands of years human activity has almost everywhere left its mark? Bridget Kendall asks the gardener Gilly Drummond, the land artist Danae Stratou, the archaeobotanist Dorian Fuller, and the historian William Beinart.
