First look at Alan Turing exhibition

Rory Cellan-Jones gets a sneak preview of an exhibition dedicated to the life of work of scientists and computer pioneer Alan Turing.

This week sees the 100th anniversary of the birth of Alan Turing, a man regarded as one of the most influential British scientists of the 20th Century.

He is best known for his work as a cryptographer, cracking the Germans' secret codes during the Second World War at Bletchley Park. He is also regarded as one of the pioneers of computer technology.

An exhibition devoted to his life and achievements opens at the Science Museum in London on 21 June.

While the exhibition was still being set up, the BBC was granted an exclusive preview.

Curator David Rooney showed technology correspondent Rory Cellan-Jones around some of the show's key exhibits.
