A British Army officer, he moved to intelligence work after being wounded during the First World War, initially working with the Indian Army and then at the Government Code and Cypher School (GC&CS). His intelligence work was largely connected with cryptography, and he showed exceptional skill at cryptanalysis. He was considered one of Bletchley Park’s finest cryptanalysts on non-machine systems and worked with Bill Tutte on the cryptanalysis of the Lorenz cypher. In 1944, he was appointed deputy director of GC&CS and continued there until 1949 when he moved to the US Army Security Agency as a liaison officer. He eventually became a consultant and researcher at the US National Security Agency. In September 2004, he was inducted into the ‘NSA Hall of Honor’, the first non-US citizen to be recognised in that way. The NSA commented:‘His efforts at training and his attention to all the many facets that make up cryptology inspired the best in all who encountered him.’
