A 56-page handwritten notebook that belonged to Alan Turing just sold for $1,025,000 at Bonhams auction house. Turing was the English mathematician widely considered the father of modern computer science. The notebook dates back to 1942, when Turing was working at Bletchley Park to crack the Enigma Code. Inside are his personal thoughts on mathematics, written in his own hand.
“The Leibniz notation Image removed by sender. I find extremely difficult to understand in spite of it having been the one I understood the best once! It certainly implies that some relation between x and y has been laid down eg, y=x2+3x…” – a part of the manuscript reads.
The sale happened at Bonhams Fine Books and Manuscripts Sale, and some of the money goes to charity. If Turing’s story sounds familiar, you probably saw The Imitation Game back in 2014. Have you seen it?
