Alan Turing: Assistant Mike Woodger recalls working with the computer pioneer

Alan Turing would have celebrated his 100th birthday on 23 June were he still alive. But the codebreaking genius died in 1954 after consuming cyanide - an act many have linked to his prosecution for being a homosexual.

Mike Woodger worked as an assistant to Alan Turing in 1946. This was the year that Turing, fresh from his wartime work code-breaking, joined the National Physical Laboratory, in Teddington.

Turing left after a year, but Mr Woodger stayed on to work on the completion of the Pilot Ace Computer, which Turing had helped to design. For a period, it was the world's fastest computer.

He recalled for BBC News what it was like to work with Alan Turing.
