Elmer Ambrose Sperry (October 12, 1860 – 16 June 1930) was an inventor and entrepreneur.

Born at Cortland, New York, Sperry spent three years at the state normal school there and became interested in dynamo electricity during a year of study at Cornell University in 1878 and 1879. He moved to Chicago, Illinois, early in 1880 and, soon thereafter, founded the Sperry Electric Company. In 1900, Sperry established an electrochemical laboratory at Washington, D.C., where he and his associate, Clifton P. Townshend, developed a process for making pure caustic soda from salt and discovered a process for recovering tin from scrap metal. Sperry experimented with diesel engines and gyroscopic compasses and stabilizers for ships and aircraft. In 1910, he started the Sperry Gyroscope Company in Brooklyn, New York; and his first compass was tested that same year in USS Delaware (BB-28). His compasses and stabilizers were adopted by the United States Navy and used in both world wars. In 1918, he produced a high-intensity arc lamp which was used by both the Army and Navy. After setting up eight companies and receiving over 400 patents, Sperry died at Brooklyn, on 12 June 1930.

His companies included:

Sperry Electric Mining Machine Company, (1888);
Sperry Electric Railway Company, (1894);
Chicago Fuse Wire Company, (1900); and
Sperry Gyroscope Company (1910), founded to manufacture Sperry's development of the gyrocompass, originally invented by Herman Anschütz-Kaempfe in 1908. Sperry's first model was installed on the battleship USS Delaware in 1911.

The companies eventually evolved into the Sperry Corporation.

Sperry was also a founding member of the US Naval Consulting Board, 1915.

In 1916, Sperry joined Peter Hewitt to develop the Hewitt-Sperry Automatic Airplane, one of the first successful precursors of the UAV.

USS Sperry (AS-12) was named for him.
