    • Q: What are some of the key dates in Alan Turing's life and why?
    • A: Alan Turing was a British mathematician, computer scientist, and logician who made significant contributions to the field of computer science and artificial intelligence. He was born on June 23, 1912 and died on June 7, 1954.

      Some key dates in Turing's life include:

      • September 26, 1931: Turing enrolls at King's College, Cambridge, where he studies mathematics and becomes interested in the foundations of computer science.
      • September 1939: Turing begins working at the Government Code and Cypher School at Bletchley Park, where he leads a team of codebreakers working to decipher German military communications during World War II.
      • May 1941: Turing and his team at Bletchley Park successfully decrypt the first messages sent using the German Enigma machine, a major breakthrough that greatly aided the Allied war effort.
      • 1952: Turing proposes the concept of the "universal machine," a theoretical device that could compute any computable function, now known as the Turing machine. This work is considered a key foundation of computer science.
      • June 7, 1954: Turing dies at the age of 41 in an apparent suicide. He had been convicted of homosexuality, which was a crime in the UK at the time, and had been subjected to chemical castration as punishment.



  1. A number of sources state that Winston Churchill said that Turing made the single biggest contribution to Allied victory in the war against Nazi Germany. However, both The Churchill Centre and Turing's biographer Andrew Hodges have stated they know of no documentary evidence to support this claim, nor of the date or context in which Churchill supposedly said it, and the Churchill Centre lists it among their Churchill 'Myths', see and A BBC News profile piece that repeated the Churchill claim has subsequently been amended to say there is no evidence for it. See Official war historian Harry Hinsley estimated that this work shortened the war in Europe by more than two years but added the caveat that this did not account for the use of the atomic bomb and other eventualities.
