Sir Wilfred Thesiger took nearly 40,000 photographs during his eight decades of travels throughout Africa and the Arabian Peninsula. Now, to mark 100 years since his birth, Oxford's Pitt Rivers Museum is displaying some of his most striking images.
For BBC Radio 4, the BBC's security correspondent Frank Gardner - who met Sir Wilfred several times - has been to the museum to see the photographs.
Here - with the help of museum curator Christopher Morton and archive recordings of Sir Wilfred himself - he looks back at Thesiger's appreciation of desert communities and their ways of life.
Thesiger at 100 will be broadcast on BBC Radio 4 at 1102 GMT on Monday 13 December 2010. It will then be available for seven days on the BBC iPlayer.
