The Newmanry was a section at Bletchley Park, the British codebreaking station during World War II.[1] Its job was to develop and employ statistical and machine methods in cryptanalysis of the Lorenz cipher. It worked very closely with the Testery where a complementary set of operations were performed to complete the decryption of each message. Formally called the Statistical section, it was known as the Newmanry after its founder and head, Max Newman.[2] It was responsible for the various Robinson machines and the ten Colossus computers. Some of the cryptanalysts had joint appointments with the Testery.[3]
Initially in June 1943 the section was small: Good, Mitchie, two engineers and sixteen Wrens in a small hut. By the end of the war there were 26 cryptographers, 28 engineers, 273 Wrens with ten Colossi, three Robinsons, three Tunnies, plus twenty small electronic and electrical machines. [4]
