Alan Turing Biography and Codebreaking the Enigma Machine

Portrayed by Keira Knightley in The Imitation Game movie, the real Joan Clarke discusses her engagement to Alan Turing and learning of his homosexuality. Despite Turing's interest in Clarke, she says that their relationship was not very physical. Jack Good comments that, other than Joan Clarke, the rest of the group likely didn't know until after World War II that Turing was homosexual.

Benedict Cumberbatch stars as Alan Turing, the British mathematician, cryptologist, logician, and computer scientist who was a key component in cracking Germany's Enigma code, which helped the Allies win WWII. Some historians believe that cracking the code shaved up to two years off of the fighting between Germany and the Allied forces. The movie is based on the book Alan Turing: The Enigma by Andrew Hodges.
