Turing's notebook sells for $1m

Alan Turing

Alan Turing committed suicide in 1954 as a consequence of hormone treatment to “cure” his homosexuality

A scientific notebook compiled by World War Two codebreaker Alan Turing has sold for $1m in New York.

It is one of very few manuscripts from the head of the team that cracked the Germans’ Enigma code.

The handwritten notes, dating from 1942 when he worked at Bletchley Park, were entrusted to mathematician Robin Gandy after Mr Turing’s death.

The notebook was sold at Bonhams for $1,025,000 (£700,850) to an unnamed buyer.

The Bombe machine

The Bombe logic machine that Turing helped to design enabled more than 3,000 German messages to be decoded in a day

Mr Gandy deposited Mr Turing’s papers at the Archive Centre at King’s College in Cambridge in 1977.

But Mr Gandy retained the 56-page notebook because of a deeply personal message written in the blank centre pages of the notebook which he wanted to keep private.

The notes remained hidden among personal effects until after his death.

Scholar Andrew Hodges, said: “Alan Turing was parsimonious with his words and everything from his pen has special value.

“This notebook shines extra light on how, even when he was enmeshed in great world events, he remained committed to free-thinking work in pure mathematics.”

Mr Turing committed suicide in 1954 as a consequence of hormone treatment to “cure” his homosexuality which he was undergoing as an alternative to imprisonment.

The story of his life was told in the 2014 Oscar-winning film The Imitation Game.
