A notebook containing handwritten mathematical notes by Alan Turing has sold for $1,025,000 (£696,800) at an auction in New York.
According to the auctioneer, Bonhams, the 56-page notebook contains writing appearing to date from 1942, when Turing was working at Bletchley Park on the German Enigma code. It is “almost certainly the only extensive autograph manuscript by Turing in existence”, Bonhams said.
The notebook was left to mathematician Robin Gandy in Turing’s will.
