A New Chapter
In 1938, Turing was recruited to work on codebreaking at the Government Code and Cypher School (GC&CS) at Bletchley Park.
Turing signed the Official Secrets Act (1939), pledging not to reveal information about his work at Bletchley.

Here, Turing worked on developing methods and machines for breaking the German Enigma code, crossing frontiers in cryptography.

He designed the Bombe, which tested possible combinations of letters in order to find the correct decryption key, turning the tide of the war.
"Turing did not look like a superstar, he was a very modest man, but Turing was the genius who broke Naval Enigma and invented the Bombe to speed up breaking of Enigma traffic. Up to the time when he broke it, Britain had been losing tremendous tonnages of shipping, including all our food imports."

"Turing was a brilliant man, but also quite eccentric. He had a peculiar sense of humor and was always coming up with new ideas and theories."
- Dilly Knox, codebreaker who worked alongside Turing
