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.Produced by Fiona Clampin for the BBC World Service.(Photo: Harry Houdini chained up ready to jump into Charles River, Boston, Massachusetts in 1906.

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.

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.(Photo: Cervantes Monument in Madrid, Spain showing Don Quixote and Sancho Panza.

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.(Photo: Volvox algae colonies, spherical forms outlined by biflagellate cells interconnected by cytoplasmic bridges.

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.

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.[Image: Portrait of Laskarina Bouboulina, 1830, by Adam Friedel.

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.Producer: Fiona Clampin (Photo: Royal Bank of Scotland £10 note featuring Mary Somerville)

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.[Photo: Malayan police officers keeping watch from the Pengkalan police station in 1950.

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. [Image: A production of The Devils staged at the Union Theatre, London.

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.[Image: Hugh of Saint-Cher, 1351-1352.
