Little David grew up in Leicester on the campus of a university, where his father was a professor. As a child, he spent hours in the science library, collating his own specimens and creating a mini animal museum.
When he was old enough to go to university, he studied science and zoology - but what he wanted most of all was to be close to the animals he was studying.
So, he started working in television, visiting animals in their natural habitats and telling the world their untold stories.
This has been a super seller edition as he's one of our nations most loved icons.
