Ralph P. Tester was an administrator at Bletchley Park, the British codebreaking station during World War II. He founded and supervised a section named the Testery for breaking TUNNY (a Fish cipher). TUNNY had twelve wheels, was most advanced, more complex, faster and far more secure then three wheels Enigma. TUNNY was used to encipher top-secret messages between German Army H.Q. in Berlin and the top generals and field-marshals on all fronts, include Adolf Hitler himself.
