[1] Keith Batey was at Carlisle Grammar School and went on to study mathematics at Trinity College, Cambridge, under a state scholarship, where he met Gordon Welchman, who would later assemble a group of code-breakers for Bletchley Park at the outbreak of the war.
[3] Batey was recruited by Welchman in 1940 and worked in Hut Six, which was responsible for breaking the German Army and Air Force Enigma ciphers.
[1] While there he met fellow code-breaker, Mavis Lever, who worked with Dilly Knox's research section, reconstructing new Enigma machines as they were introduced.
In 1942, Batey wished for a more physically active role in the war as a pilot in the RAF, but was rejected due to his knowledge of Ultra and the risk of getting captured.
[4] The Bateys demonstrated how the Abwehr Enigma machine worked during a visit by Prince Charles and the Duchess of Cornwall to Bletchley Park in 2008.
