Brigadier John Hessell Tiltman, (25 May 1894 – 10 August 1982) was a British Army officer who worked in intelligence, often at or with the Government Code and Cypher School (GC&CS) starting in the 1920s.
His intelligence work was largely connected with cryptography, and he showed exceptional skill at cryptanalysis.
His work in association with Bill Tutte on the cryptanalysis of the Lorenz cipher, the German teleprinter cipher, called "Tunny" (for tunafish) at Bletchley Park, led to breakthroughs in attack methods on the code, without a computer.
It was to exploit those methods, at extremely high speed with great reliability, that Colossus, the first digital programmable electronic computer, was designed and built.
