Direct answers to common questions about Alan Turing, followed by the full sourced biography.
Mathematician whose work shaped computing, codebreaking and artificial intelligence. Turing developed the abstract concept of a universal computing machine before joining British wartime cryptanalysis at Bletchley Park. His work contributed to methods for attacking German Enigma traffic and to early electronic computing after the war. Prosecuted for homosexual activity in 1952, he was.
Alan Turing is particularly known for Mathematician whose work shaped computing, codebreaking and artificial intelligence., Science and Technology.
Alan Turing lived 1912–1954. This profile places that life within 20th Century and Science and Technology.
Official apology and pardon recognised the injustice done to Turing, though thousands of other men were convicted under the same laws. Public memory should celebrate his work without turning collective scientific and intelligence history into a solitary-genius myth.
Turing developed the abstract concept of a universal computing machine before joining British wartime cryptanalysis at Bletchley Park. His work contributed to methods for attacking German Enigma traffic and to early electronic computing after the war. Prosecuted for homosexual activity in 1952, he was subjected to hormonal treatment and died two years later.
Turing studied mathematics at Cambridge and Princeton. His 1936 paper defined a universal abstract machine to clarify what it means for a problem to be computable. The work became foundational to theoretical computer science.
At Bletchley Park, Turing worked principally on German naval Enigma and helped develop methods and machines for testing possible settings. Intelligence success depended on Polish breakthroughs, operators, engineers, captured material and a large organisation; no individual 'broke Enigma' alone.
After the war Turing designed an electronic stored-program computer at the National Physical Laboratory and worked on the Manchester computers. His 1950 paper proposed an imitation game as a practical way to discuss machine intelligence.
Police investigation of a burglary exposed Turing's relationship with Arnold Murray. Convicted of gross indecency in 1952, he accepted hormonal treatment rather than prison and lost security access. He died from cyanide poisoning in 1954; the inquest found suicide.
