In 1954, the BBC broadcast a new television programme in Britain. It was called Zoo Quest and it launched the career of a man who has since brought the natural world into millions of homes around the world, the broadcaster Sir David Attenborough. Louise Hidalgo has been listening back through the BBC archives to Sir David telling the story of the first natural history expedition for Zoo Quest, to Sierra Leone in West Africa.
