Geoffrey O’Hanlon (1885-1975) was a classics master at Sherborne School, Dorset. In 1920 he purchased for the school a new boarding house named Westcott House. It was suggested to Sara Turing that Alan would be best suited to O'Hanlon's house, the regime being likened to 'the nearest thing to a liberal government' (Hodges p.23). The dates of Turing's signatures denote that he visited Westcott House three times in his first two years up at King's College, Cambridge. Other interesting signatures include that of Alan’s brother, John, visiting Sherborne 20-22 June 1931, in Alan's last term at school. According to our research, NO ALAN TURING SIGNATURE HAS PREVIOUSLY BEEN SOLD AT AUCTION.
