William E. Sawyer
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 Albion 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. Use of the Sawyer-Man 'stopper' lamps allowed Westinghouse to successfully bid for the contract to illuminate the 1893 Chicago World's Fair, a key development in the War of Currents. The Sawyer-Man company was eventually purchased by the Westinghouse Corporation and became the Westinghouse lighting division.
