Sir Dermot Turing will talk about the origins of Enigma codebreaking at Bletchley Park, the Bombe machine and how it worked. In 1939, six weeks before the outbreak of World War 2, the British codebreakers knew next to nothing about the German military Enigma machine. How was it that, by mid-autumn, they had already designed the Bombe machine which would win the codebreaking war? Join us in the build up to our Bletchley Park Week series of events (3rd – 7th March 2019), for this fascinating talk by Sir Dermot Turing, author and nephew of the Bletchley Park cryptanalyst Alan Turing.
