Great Lives

Seretse Khama was born in 1921 in Bechuanaland when it was still a British Protectorate. In 1966 he became Botswana's first president. In between he married a white Londoner, Ruth Williamson, was exiled by the British, and made to renounce his interest in succeeding as head of the Bangwato. It's an extraordinary and notable life, and he's been nominated by Professor Mike Bode, an astrophysicist and visiting professor to Botswana. As well as archive of Seretse Khama, the programme includes contributions from Bishop Trevor Mwamba and Susan Williams, author of Colour Bar: The Triumph of Seretse Khama and His Nation.

For over a hundred years no one thought too much about the origins of the RSPB, but among its founders was a woman in Didsbury opposed to the use of feathers in fashionable hats. Emily Williamson was outraged by the widespread slaughter of egrets and the crested grebe. She had tried to join the all-male British Ornithological Union, and when that failed she established her own Society for the Protection of Birds. Nominating Emily is Hannah Bourne-Taylor, author of Fledgling and Nature Needs You, which is about her own campaign for the introduction of swift bricks into all new buildings. Helping Hannah discover more about this little known life is author Tessa Boase, who discovered Emily's role; plus Beccy Speight the current head of the RSPB. Matthew Parris presents.

The chef Raymond Blanc nominates his mentor and friend, the physicist Professor Nicholas Kurti. Kurti was born in Hungary but fled to Oxford when Hitler came to power. Pushing the frontiers of low-temperature physics during his career, he went on to create‘molecular gastronomy’ in retirement. Raymond Blanc approached Kurti after a lecture the professor gave in his 80s. Blanc asked to help him understand the science behind his trials with leaky puff pastry and souffles that wouldn’t rise. Kurti agreed and so began a friendship of fun and great respect. As Raymond Blanc says; “Imagine! Two complete geniuses!” Raymond Blanc also promises to give Matthew “The best steak of your life”.
