Elmer Sperry

Born 12 Oct 1860; died 16 Jun 1930 at age 69.Elmer Ambrose Sperry was an American engineer and inventor who devised the gyrocompass. In the 1890's he made useful inventions in electric mining machinery, and patent electric brake and control system for street- or tramcars. In 1908, he patented the active gyrostabilizer which acted to stop a ship's roll as soon as it started. He patented the first gyrocompass designed expressly for the marine environment in 1910. This "spinning wheel" gyro was a significant improvement over the traditional magnetic compass of the day and changed the course of naval history. The first Sperry gyrocompass was tested at-sea aboard the USS Delaware in 1911 and established Sperry as a world leader in the manufacture of military gyrocompasses for the next 80 years.
