Turing read mathematics at King's College, Cambridge. He was elected Fellow of King's in 1935. He began research in mathematical logic which led to his well-known work on computable numbers and the 'Turing Machine.' He spent two years at Princeton University, 1936-1938, working with A. Church, and the war years at Bletchley Park, at the Code and Cypher School, 1939-1945, and was awarded the OBE for his work on 'Enigma' and other codes. At the end of the war he declined a Cambridge University Lectureship and joined the group that was being formed at the National Physical Laboratory, Teddington for the design, construction and use of a large automatic computing machine. In his three years at the NPL, 1945-1948, he made the first design of the ACE computer and did much of the pioneering work in the design of sub-routines. In 1948 he was appointed Reader in Mathematics at Manchester University where work was beginning on the construction of a large computer by F. C. Williams and T. Kilburn. Towards the end of his life Turing was increasingly interested in morphogenesis. He was elected FRS in 1951.
