Richard Wesley Hamming (February 11, 1915 – January 7, 1998) was a mathematician whose work had many implications for computer science and telecommunications. His contributions include the Hamming code (which makes use of a Hamming matrix), the Hamming window (described in section 5.8 of his book Digital Filters), Hamming numbers, Sphere-packing (or hamming bound) and the Hamming distance.

He was born in Chicago and died in Monterey, California. He received his bachelor's degree from the University of Chicago in 1937, a master's degree from the University of Nebraska in 1939, and finally a Ph.D. from the University of Illinois at Urbana-Champaign in 1942. He was a professor at the University of Louisville during World War II, and left to work on the Manhattan Project in 1945, programming one of the earliest electronic digital computers to calculate the solution to equations provided by the project's physicists. The objective of the program was to discover if the detonation of an atomic bomb would ignite the atmosphere. The result of the computation was that this would not occur, and so the United States used the bomb, first in a test in New Mexico, and then twice against Japan.

Hamming tries to extract general lessons -- both personal and technical -- to aid one in having a successful technical career by telling stories from his own experiences. (Some of this material relating to the self-management of one's technical career can be found online at the You and Your Research link; see below.) One of Hamming's lessons is never trust without question someone who claims to be giving you highly accurate data to analyze -- not because they're deliberately lying to you but because the data is never as accurate as people think.
