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][4]
