Sir David Attenborough is a broadcaster and naturalist whose television career is now in its seventh decade. After studying Natural Sciences at Cambridge and a brief stint in publishing, he joined the BBC in 1952 and spent ten years making documentary programmes of all kinds, including the Zoo Quest series. In 1965, he was appointed Controller of a new network, BBC2, and then, after four years became editorially responsible for both BBC1 and BBC2.
After eight years of administration, he returned to programme-making to write and present a thirteen-part series, Life on Earth, which surveyed the evolutionary history of animals and plants. This was followed by many other series which, between them, surveyed almost every aspect of life on earth.
