1894: Brigadier John H. Tiltman, only foreign citizen in Cryptologic Hall of Honor was born in London.

25 May 1894: Brigadier John H. Tiltman was born in London on this date. Tiltman is the only foreign-born citizen in the NSA/CSS Cryptologic Hall of Honor. (See link below.) Considered one of Bletchley Park's finest cryptanalysts on non-machine systems, Tiltman also had an important role in solving the German TUNNY machine system. He was an early and persistent advocate of British cooperation with the United States in cryptology. All totaled, he spent 60 years at the cutting edge of SIGINT. Learn more about him in the NSA Publication, "Brigadier John Tiltman: A Giant Among Cryptanalysts" via the link below.

John Tiltman made the transition from the manual ciphers of the early 20th century to the sophisticated machine systems of the latter half of the century. "The Brig," as he was affectionately known in both countries, compiled a lengthy record of high achievement. His efforts at training and his attention to all the many facets that make up cryptology inspired the best in all who encountered him.
