Arnold I. Dumey (1906-1995) was the co-inventor of the postal sorting machine and cryptanalyst first for SIS and then NSA. During World War II he worked for the Army Signal Corps and at Arlington Hall, headquarters of the US Army's Signals Intelligence Service (SIS) cryptography, under William and Elizabeth Friedman on breaking the German and Japanese codes. Dumey is also considered by some the inventor of hashing. He published the first hashing paper in 1956.
