28/03/2014

Captain Raymond 'Jerry' Roberts, one of the last surviving Bletchley Park codebreakers has died.

Captain Roberts was a linguist and became one of the first members of the Testery set up by Major Ralph Tester in 1941.

Breaking codes by hand, the Testery successfully deciphered the most complex cipher of the war, Tunny (Lorenz), which was used in communications between Hitler and his generals.

This work, later assisted by the Colossus computer, is widely believed to have shortened the war by two years and saved countless lives.
