From Wikipedia, the free encyclopedia.
Elmer Ambrose Sperry (October 12, 1860 - June 16, 1930) was an inventor and entrepreneur. Born Cortland, New York, died Brooklyn, New York.
In 1880, he founded the Sperry Electric Company in Chicago, Illinois to manufacture the electric dynamos and arc lamps that he had invented as a teenager. Over the next fifty years, he founded seven more companies to manufacture his own inventions, including:
- Sperry Electric Mining Machine Company (1888);
- Sperry Electric Railway Company (1894);
- Chicago Fuse Wire Company (1900); and
- Sperry Gyroscope Company (1910).
The companies eventually evolved into the Sperry Corporation.
