"Make the boy interested in natural history," wrote Captain Scott from his tent in the Antarctic. He was talking about his son, three year old Peter Scott, whom he never saw again and who went on to found the Wildfowl and Wetland Trust and campaign against the hunting of whales. The son also designed the panda logo for the Wold Wide Fund for Nature and was its first chairman. David Attenborough called Scott the patron saint of conservation and he appears in this programme. Nominating him in studio is the adventurer Pen Hadow, whose father knew Scott and with whom he shared a nanny. The programme also features two of Scott's children, Dafila and Falcon, as well as some rarely heard archive. From his early years as an arctic adventurer, Pen Hadow has developed into an ardent conservationist with the 90 North Foundation. He describes this programme as an enormous responsibility and wonders why Sir Peter Scott, the founder of Slimbridge, is not better known today.The producer for BBC Audios Studio in Bristol is Miles Warde

Margot Fonteyn was an icon: a ballerina who helped build and indeed embodied the traditional image of a dancer, just as the artform was finding its feet on the British cultural scene. From humble beginnings she became an international star, enjoying a dazzling career with the Royal Ballet, a glamorous social life as a diplomat’s wife, and an electric dancing partnership with Rudolf Nureyev. But it was also a life infused with disappointment, controversy and heartbreak; much of which seems to have been hidden behind Margot's smiling public facade. Dedicated listeners might remember that Margot Fonteyn has been the subject of a previous episode and although we rarely revisit past greats, when we do it’s an opportunity to look afresh and see more. So today, with the assistance of nominating guest Lauren Cuthbertson - herself a dancer who has been with the Royal Ballet for more than 20 years - we take a closer look at the highs and lows of Margot's life. Joining Matthew and Lauren to share their expert perspectives are Rosie Gerhard, a Lecturer in Dance Studies at the Royal Academy of Dance and creator of the blog 'British Ballet Now & Then'; and the film director and author Tony Palmer, who directed the 2005 film ‘Margot’.Presented by Matthew Parris and produced for BBC Studios Audio by Lucy Taylor.

Today neurosurgeon Dr Henry Marsh chooses “the saviour of mothers” Dr Ignaz Semmelweis The Hungarian doctor discovered the link between childbirth and puerperal fever in 19th century Vienna but he was ridiculed, ignored and demoted as his discovery challenged the medical orthodoxy. Post-mortems at the time were carried out by doctors before they practised on wards, with no hygiene step between the two. Semmelweis recommended handwashing for doctors, and gathered statistics to prove his theory.Despite the evidence, the medical establishment was resistant to change and Semmelweis became increasingly traumatised, frustrated and angry. In his final months, he seems to have also developed an organic brain disorder which led to his friends and wife having him restrained and sectioned in a mental asylum where he subsequently died from injuries. Nominator Dr Henry Marsh is the author of Do No Harm: Stories of Life, Death and Brain Surgery. With the playwright Stephen Brown who cowrote Dr Semmelweis with Sir Mark Rylance.
