William Edward Sawyer (1850-May 15, 1883)〔 〕 was an American inventor whose contribution was primarily in the field of electric engineering and electric lighting. His primary inventions included: * Telegraph apparatus for cable use (March 31, 1874) * Automatic and autographic telegraph and circuit (February 2, 1875) * Electric engineering and lighting apparatus and system (August 14, 1877) * Device for effecting the static discharge in autographic telegraphy (November 6, 1877) * Electric switch (June 29, 1880) * Electrical safety device for elevators (July 6, 1880) A 1920 article in ''The New York Times'' described him as best known for pioneering the development of the incandescent light.〔 〕 In partnership with Albon Man (June 29, 1826- February 18, 1905) he founded a company to produce incandescent lamps. From 1879 thorough 1885 the company successfully defended his patents against the interests of the Edison company. The patent was controlled by the Thomson-Houston Electric Company until 1888 when Westinghouse Electric bought the company producing the lamp, Consolidated Electric Light.〔Maury Klein, The Power Makers: Steam, Electricity, and the Men Who Invented Modern America, Bloomsbury Publishing USA - 2010, page 281〕 Sawyer-Man based 'stopper' lamps, although not as long lasting as the Edison lamp, did allow Westinghouse to successfully illuminate the Chicago World's Columbian Exposition of 1893. The Sawyer-Man company was eventually purchased by the Westinghouse Corporation and became the Westinghouse lighting division. 〔 F. A.
