In this episode, we continue our focus on the attack on the Lorenz code that Bill Tutte played such an important part in, with a first-hand account.
Captain Jerry Roberts worked with Bill Tutte in The Testery breaking, what was referred to as ‘Tunny’, the code used by the German High Command – Hitler and his top Generals. Jerry tells us what it was like to work in The Testery, why breaking Tunny was so important to the ultimate Allied victory and of his three heroes of Bletchley Park.
Jerry’s was the last of a day of talks held in 2012 as part of the celebrations of Alan Turing’s Centenary. The introduction is by Lord Charles Brocket who acted as master of ceremonies for the day.
In memoriam, Captain Jerry Roberts MBE (1920-2014)
