Oral history interview with Thomas Harold Flowers, ca. 1976.

Flowers discusses the development of the Colossus electronic cryptanalytic machine beginning with his work for the British government in switching systems. As early as 1930, he says, he turned to vacuum tubes because of reliability problems with mechanical switching equipment. He describes the construction of a voice-frequency signalling system at the Post Office Research Establishment (PORE) from 1932 to 1935. At the beginning of World War II PORE directed its efforts to cryptanalysis, and Flowers' expertise in vacuum tube switching led him to a key role in the project. Flowers describes in detail his work with Colossus at the Bletchley Park Government Code and Cipher School, and his relationship with Alan Turing, one of the senior Bletchley Park scientists.

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 Lec...
