A 56-page handwritten notebook that belonged to Alan Turing, the English mathematician considered to be the father of modern computer science, sold for $1,025,000 at Bonhams auction house. The notebook dates back to 1942 when Turing was working at Bletchley Park to break the Enigma Code.
“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 auction was part of Bonhams Fine Books & Manuscripts Sale, with part of the proceeds going to charity. Turing’s life and work were recently brought to life in the 2014 blockbuster ‘The Imitation Game’. Have you seen it?
