W. Edwards Deming

Born 14 Oct 1900; died 20 Dec 1993 at age 93.W(illiam) Edwards Deming was an American statistician, the father of "Total Quality Management." After WW II, he contributed to Japan's economic recovery by recommending statistical methods of quality control in industrial production. His method embraced carefully tallying product defects, examining their causes, correcting the problems, and then tracking the results of these changes on subsequent product quality. In his career before the war, he had developed statistical sampling techniques that were first used in the 1940 U.S. census. From the 1980's in the U.S. Deming taught quality control through the statistical control of manufacturing processes for companies such as Ford, Xerox, and GM.«
