TURING, Sara.
Inquire · Offered by Peter Harrington
Alan M. Turing. First edition, one of 500 copies only. This biography of the great computer science pioneer sought to establish Turing's credentials without reference to his then still-classified war work. "Written from a mother's viewpoint, Sara provides a unique insight into the early years of Turing, with candid descriptions, anecdotal accounts of Turing's eccentricity and genius, and insights into his science" (Cooper). Sara (1881-1976) maintained that her son's death was an accident and the result of careless handling of chemicals when preparing "non-poisonous weed-killer and sink-cleaner" (p. 115) rather than the inquest's verdict of suicide.
