William E. Sawyer

William Edward Sawyer (c. 1850 – May 15, 1883)[1] 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 inThe New York Times described him as best known for pioneering the development of theincandescent light.[2]In partnership withAlbon Man (June 29, 1826- February 18, 1905) he foundedElectro-Dynamic Light 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 theThomson-Houston Electric Company until 1888 whenWestinghouse Electric bought the company producing the lamp,Consolidated Electric Light.[3] Sawyer-Man based 'stopper' lamps, although not as long lasting as the Edison lamp, did allow Westinghouse to successfully illuminate the ChicagoWorld's Columbian Exposition of 1893. The Sawyer-Man company was eventually purchased by the Westinghouse Corporation and became the Westinghouse lighting division.[4]
