Summary

Elmer A. Sperry was born on October 12, 1860, in Cortland, N.Y. He attended the local elementary schools and then enrolled in Cornell University. At Cornell, he developed an interest in electrical engineering and began working with a group of Syracuse industrialists in order to construct an arc lighting system. By 1882 Sperry was recognized as being one of America's electrical pioneers. In 1883 Sperry moved to Chicago where he established the Electric Light, Motor, and Car Brake Company. He, however, found that he could not compete with the more established Edision and Brush Electric companies so he began experimenting with electric coal-mining equipment. In l886 he founded the Sperry Electric Mining Machine Company. During these years Sperry also developed an electric street car. After selling his patents to General Electric, he went to work for the company as a consultant. In 1901 Sperry became associated with a young patent examiner, Clifton Townsend, and the two men worked together to develop an electrolytic process to manufacture white lead. Sperry and Townsend opened a production plant in Niagara Falls, N.Y., which was sold to Elon Hooker's Development and Funding Company. In 1907 Sperry began to experiment with the gyroscope. Three years later, he founded the Sperry Gyroscope Company in Brooklyn, N.Y., in order to develop, manufacture, and market marine gyrostabilizing devices. Working closely with the Navy, he developed the gyrocompass, ship stabilizer, and high-intensity search light. During the First World War, the Sperry Gyroscope Company became a major defense contractor, and Elmer Sperry sat on the Naval Consulting Board. After the war, Sperry Gyroscope moved into aeronautics as it developed airplane stabilizers, gyrostabilized bombsights, and the aerial torpedo. Elmer Sperry died on June l6, l930. The Elmer Sperry papers document Sperry's research and development work and entrepreneurial activities. The Chicago-Cleveland records describe his efforts to develop arc lighting systems, stationary power, electric mining machinery, and electric traction technology. Included are correspondence files and financial records of the Electric Light, Motor, and Car Brake and the Electric Mining Machine companies. Electro-chemistry files include correspondence and reports documenting the development of the white lead process and the business negotiations that took place between the Sperry and Hooker Chemical companies. Also included is correspondence with William F. Dutton of the American Can Company, Leo Baekeland, and with Ernest LeMaire of the Hooker Electrochemical Company. Gyroscope company records document the development and marketing of the marine and aeronautical instruments, including the gyrocompass, ship stabililzer, high-intensity search light, airplane stabilizer, fire control systems, automatic bombsights, and the aerial torpedo. These records describe Sperry's close working relationship with the U.S. Navy and his collaboration with Admiral David W. Taylor and Commander William McEntree. Records also describe Sperry's activities on the Naval Consulting Board. Sales and marketing records contain correspondence with representatives of the British, French, Japanese, and Russian navies.
