Jerry Roberts has died

One of the last surviving Bletchley Park codebreakers, Jerry Roberts, has died aged 93. He was one of a small group of codebreakers who decrypted messages from the German High Command, including the German plans for the battle of Kursk. He initially worked on the Double Playfair hand cipher used by the German police, and later was part of the team working on the (more difficult than the well-known Enigma) Lorenz cipher, which used two sets of five cipher wheels.

Roberts had a successful career after the war in market research, and was a campaigner in later years for greater recognition for his fellow codebreakers – including William Tutte and Tommy Flowers, who had built the Colossus computer which cracked the codes, and Alan Turing, who also apparently did something.
