Bombe 80th Anniversary Celebration

We invite you to join us at The National Museum of Computing on Bletchley Park to celebrate the 80th anniversary of the delivery of the first Bombe to Bletchley Park in 1940.

Our speakers are the world’s two leading experts on Enigma codebreaking – from Poland, Dr Marek Grajek and from the UK, Sir Dermot Turing. Together they will tell the story of the run-up to the outbreak of war and the major contribution of the Polish codebreakers who passed their insights to the French and British at Pyry in July 1939.

They will then attempt to unravel the little-understood process by which the Poles’ knowledge and practical expertise combined with the insights of the Bletchley Park team (which included Dilly Knox and Alan Turing working closely with Harold 'Doc' Keen from the British Tabulating Machine company) who managed to conceive, design, construct and commission the first Bombe for delivery to BP on 18 March 1940 – less than nine months after the Pyry meeting.

In the afternoon, there will be a unique opportunity to see the impact of Gordon Welchman’s Diagonal Board on the performance of the Bombe when for the first time the Bombe will run the same menu twice, once without the Board and then with it in place.
