A lost and unique collection of letters and correspondence from the late Alan Turing has been found in an old filing cabinet in a storeroom at the University of Manchester.
The file’s content, which potentially hasn’t seen the light of day for at least 30 years, dates from early 1949 until Turing’s death in June 1954.Altogether there are 148 documents, including a letter from GCHQ, a handwritten draft BBC radio programme about Artificial Intelligence (AI) and offers to lecture from some of America’s most famous universities, such as Massachusetts Institute of Technology (MIT).
The file contains very little about Turing’s personal life and the events around his well-documented conviction for an illegal sex act in 1952, enforced hormone treatment and tragic suicide in 1954. Plus, Turing’s war work on Enigma was still top secret at this time so, apart from a single letter from the director of GCHQ about Bletchley Park, it is not mentioned in the correspondence.
But the letters do give a unique glimpse into his every day working life at the time of these events. Plus, some documents also give a brief insight into some of his more forthright personal opinions. For example, his response to a conference invitation to the US in April 1953 is simply, “I would not like the journey, and I detest America”.
The documents were found by Professor Jim Miles of the School of Computer Science, who is also the School’s history co-ordinator. Prof Miles was reorganising the storeroom when he came across an ordinary looking red paper file which had the words Alan Turing written on it.
A lot of the letters focus on Turing’s research and his forward, ground-breaking thinking in areas such as AI, computing and mathematics.
