Bonham’s New York sold Alan Turing’s Wartime Manuscript for $1,025,000, April 13, 2015

My goal is to publish new posts twice a week — Mondays and Thursdays. However, if you don’t see a new post on Thursday, it’s because I was too busy, so please look for a new one the following Monday.


Alan Turing

Alan Turing

You may know of Alan Turing from history or the latest movie about him, The Imitation Game, starring Benedict Cumberbatch. In a nutshell, Alan Turing is considered by many to be the father of modern computing. His work during WW II helped the Allies break the German Enigma codes and speed the end of the war.

On Monday, April 13, 2015, Bonham’s New York sold an original, hand-written manuscript by Alan Turing — the only known example. The 56 pages of mathematical notes on logic were probably written in 1944. The auction house did not disclose a pre-auction estimate in their catalog, but it was available as “Estimate on request”. It sold for $1,025,000, including buyer’s premium — probably helped by the publicity from the movie.
