Bletchley Park Codebreakers (jan 1, 1939 – jan 1, 1987)

Description:

At first GC&CS followed its pre-war recruitment policy and looked for ‘Men and women of a professor type’ through contacts at Oxford and Cambridge universities. Many famous Codebreakers including Alan Turing, Gordon Welchman and Bill Tutte were found this way. Others such as Dilly Knox and Nigel de Grey had started their codebreaking careers in WW1. The organisation started in 1939 with only around 150 staff, but soon grew rapidly.

In 1987 Bletchley Park closed.
