Alfred M. Moen
As a mechanical engineering student at the University of Washington (which he did not graduate ), he worked in 1937 in passing in a car repair shop in order to pay his tuition can. When he tried to wash at night on the way home 'hands, he scalded at the usual faucet with two valves, the hand. He then began to think about a mixer battery.
His first design was a double - valve faucet with a cam for controlling the two valves, but potential producers were not impressed. Between 1940 and 1945 he made several more drafts, but in the time of the Second World War there was no manufacturer who could start production. Later Moen worked as a toolmaker at a naval shipyard in Seattle. In 1947 he was able to persuade the company Ravenna Metal Products to finance his newest design and produce. Was first sold its product in San Francisco for $ 12.
The invention led to the creation of Moen, Inc. in North Olmsted, Ohio, now 3500 employees and is one of the world's biggest manufacturers of faucets. There he was head of research and development department, until he retired in 1982.
