Footnotes

  • One of the most important twentieth century computer papers, in which Turing introduces the concept of a computing device that would replicate the mathematical reasoning abilities and thought processes of the human brain. In 1933, Turing had the rare honour as an undergraduate of being invited to read to the Moral Science Club at Cambridge - an event noted by the philosopher R.B. Braithwaite in the Club's minutes.

    In a letter from Princeton dated 22 February, 1937, Turing wrote to his mother that "Braithwaite at Kings" had asked for a "reprint" of On Computable Numbers, and that "possibly it is making a certain amount of impression". Turing presumably sent the present item to fulfil the request.

    Provenance: R.B. Braithwaite (1900-1999); Professor Timothy Smiley.
