Sir Dermot Turing: “The Origins of Enigma Codebreaking at Bletchley Park” talk and book signing

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? Sir Dermot Turing will talk about the origins of Enigma codebreaking at Bletchley Park, the Bombe machine and how it worked.

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. The talk will be followed by a book sale and signing.

Refreshments will be served from 17:00, the talk will begin at 17:30 and finish at 18:15, with a further 30 minutes for the book signing.

This talk is free and open to all but booking is essential.
