A handwritten notebook by British World War II code-breaking genius Alan Turing, whose story was portrayed into the 2014 Oscar-winning movie 'The Imitation Game,' has been sold for more than $1 million.
Bonhams auctioned the 56-page manuscript on Monday. It's believed to be the only extensive Turing manuscript known to exist.
Part of the proceeds will be donated to charity.
The notebook was written at the time the mathematician and computer science pioneer was working to break the seemingly unbreakable Enigma codes used by the Germans throughout the war.
It contains Turing's complex mathematical and computer science notations.
'The Imitation Game,' starring Benedict Cumberbatch as Turing, won the Oscar for Best Adapted Screenplay.
