Background: Sir David Frederick Attenborough  (UK: ; born 8 May 1926) is an English broadcaster and naturalist. He is best known for writing and presenting, in conjunction with the BBC Natural History Unit, the nine natural history documentary series that form the Life collection, which form a comprehensive survey of animal and plant life on Earth. He is a former senior manager at the BBC, having served as controller of BBC Two and director of programming for BBC Television in the 1960s and 1970s. He is the only person to have won BAFTAs for programmes in each of black and white, colour, HD, 3D and 4K.
Context: Attenborough was born in Isleworth, Middlesex (now part of west London), but grew up in College House on the campus of the University College, Leicester, where his father, Frederick, was principal. He is the middle of three sons (his elder brother, Richard, became an actor and director and his younger brother, John, was an executive at Italian car manufacturer Alfa Romeo), and the only surviving child among them. During World War II, through a British volunteer network known as the Refugee Children's Movement, his parents also fostered two Jewish refugee girls from Europe.  Attenborough spent his childhood collecting fossils, stones and other natural specimens. He received encouragement in this pursuit at age seven, when a young Jacquetta Hawkes admired his "museum". He also spent a considerable amount of his time in the grounds of the university, and, aged 11, he heard that the zoology department needed a large supply of newts, which he offered via his father to supply for 3d each. The source, which wasn't revealed at the time, was a pond less than five metres from the department. A few years later, one of his adoptive sisters gave him a piece of amber filled with prehistoric creatures; some 50 years later, it would be the focus of his programme The Amber Time Machine.  In 1936 David and his brother Richard attended a lecture by Grey Owl (Archibald Belaney) at De Montfort Hall, Leicester, and were influenced by his advocacy of conservation. According to Richard, David was "bowled over by the man's determination to save the beaver, by his profound knowledge of the flora and fauna of the Canadian wilderness and by his warnings of ecological disaster should the delicate balance between them be destroyed. The idea that mankind was endangering nature by recklessly despoiling and plundering its riches was unheard of at the time, but it is one that has remained part of Dave's own credo to this day." In 1999, Richard directed a biopic of Belaney entitled Grey Owl.  Attenborough was educated at Wyggeston Grammar School for Boys in Leicester and then won a scholarship to Clare College, Cambridge in 1945, where he studied geology and zoology and obtained a degree in natural sciences. In 1947 he was called up for national service in the Royal Navy and spent two years stationed in North Wales and the Firth of Forth.  In 1950 Attenborough married Jane Elizabeth Ebsworth Oriel; she died in 1997. The couple had two children, Robert and Susan. Robert is a senior lecturer in bioanthropology for the School of Archaeology and Anthropology at the Australian National University in Canberra. Susan is a former primary school headmistress.  After leaving the Navy, Attenborough took a position editing children's science textbooks for a publishing company. He soon became disillusioned with the work and in 1950 applied for a job as a radio talk producer with the BBC. Although he was rejected for this job, his CV later attracted the interest of Mary Adams, head of the Talks (factual broadcasting) department of the BBC's fledgling television service.  Attenborough, like most Britons at that time, did not own a television, and he had seen only one programme in his life. However, he accepted Adams' offer of a three-month training course, and in 1952 he joined the BBC full-time. Initially discouraged from appearing on camera because Adams thought his teeth were too big, he became a producer for the Talks department, which handled all non-fiction broadcasts. His early projects included the quiz show Animal, Vegetable, Mineral? and Song Hunter, a series about folk music presented by Alan Lomax.  Attenborough's association with natural history programmes began when he produced and presented the three-part series Animal Patterns. The studio-bound programme featured animals from London Zoo, with the naturalist Julian Huxley discussing their use of camouflage, aposematism and courtship displays. Through this programme, Attenborough met Jack Lester, the curator of the zoo's reptile house, and they decided to make a series about an animal-collecting expedition. The result was Zoo Quest, first broadcast in 1954, where Attenborough became the presenter at short notice due to Lester being taken ill.  In 1957, the BBC Natural History Unit was formally established in Bristol. Attenborough was asked to join it, but declined, not wishing to move from London where he and his young family were settled. Instead, he formed his own department, the Travel and Exploration Unit, which allowed him to continue to front Zoo Quest as well as produce other documentaries, notably the Travellers' Tales and Adventure series.  In the early 1960s, Attenborough resigned from the permanent staff of the BBC to study for a postgraduate degree in social anthropology at the London School of Economics, interweaving his study with further filming. However, he accepted an invitation to return to the BBC as controller of BBC Two before he could finish the degree.  From 1983, Attenborough worked on two environmentally themed musicals with the WWF and writers Peter Rose and Anne Conlon. Yanomamo was the first, about the Amazon rainforest, and the second, Ocean World, premiered at the Royal Festival Hall in 1991. They were both narrated by Attenborough on their national tour and recorded on to audio cassette. Ocean World was also filmed for Channel 4 and later released. In 1990, he highlighted the case of Mahjoub Sharif as part of the BBC's Prisoners of Conscience series.  In May 2005, Attenborough was appointed as patron of the UK's Blood Pressure Association, which provides information and support to people with hypertension. In January 2009, the BBC commissioned Attenborough to provide a series of 20 ten-minute monologues covering the history of nature. Entitled David Attenborough's Life Stories, they are broadcast on Radio 4 on Friday nights. Part of Radio 4's A Point of View strand, the talks are also available as podcasts.  He appeared in the 2009 Children's Prom at the BBC Promenade Concerts and in the Last Night of the Proms on 12 September 2009, playing a floor polisher in Sir Malcolm Arnold's "A Grand, Grand Overture" (after which he was "shot" by Rory Bremner, who was playing the gun). In 2009, he also became a patron of Population Matters (formerly known as the Optimum Population Trust), a UK charity advocating sustainable human populations.  He is also a patron of the Friends of Richmond Park and serves on the advisory board of BBC Wildlife magazine. Attenborough is also an honorary member of BSES Expeditions, a youth development charity that operates challenging scientific research expeditions to remote wilderness environments.
