In which city did Alan Turing spend most of his post-war career?

Alan Turing spent most of his post-war career in Manchester. After working at the National Physical Laboratory in London on the ACE computer design from 1945 to 1947, he joined the University of Manchester in 1948.

Manchester was then becoming a centre of pioneering computer research. Turing joined Max Newman’s Computing Machine Laboratory, where researchers were developing early stored-program computers. Turing became a reader in mathematics and, in 1949, deputy director of the laboratory. He worked on software and programming for the Manchester Mark 1 and later advised Ferranti during the development of the commercial Ferranti Mark 1.

The city also shaped Turing’s scientific interests beyond computing. While in Manchester, he published important ideas about machine intelligence, including the 1950 paper “Computing Machinery and Intelligence,” and developed mathematical theories of biological pattern formation. Turing had earlier lived and worked in Cambridge, Bletchley Park, and London, but Manchester was his main professional base after the war until his death in 1954.
