Elmer Ambrose Sperry was a prolific inventor and entrepreneur, most famous as co-inventor, with Herman Anschütz-Kaempfe of the gyrocompass. Sperry was born at Cortland, New York, United States of America. He spent three years at the state normal school there, then a year at Cornell University in 1878 and 1879, where he became interested in dynamo electricity. He moved to Chicago, Illinois, early in 1880 and, soon after founded the Sperry Electric Company.

  • Elmer Ambrose Sperry was a prolific inventor and entrepreneur, most famous as co-inventor, with Herman Anschütz-Kaempfe of the gyrocompass. Sperry was born at Cortland, New York, United States of America. He spent three years at the state normal school there, then a year at Cornell University in 1878 and 1879, where he became interested in dynamo electricity. He moved to Chicago, Illinois, early in 1880 and, soon after 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; 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 as a searchlight by both the Army and Navy. After setting up eight companies and taking out over 400 patents, Sperry died in 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 Rail Service (1911)a railroad defect detection company. 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, as was the annual Elmer A. Sperry Award for Advancing the Art of Transportation.
  • Elmer Ambrose Sperry war ein US-amerikanischer Erfinder und Geschäftsmann. 1880 gründete er in Chicago die Sperry Electric Company, die sich mit der Herstellung von Generatoren und Lichtbogenlampen beschäftigt. Elmer Sperry gründete 1910 die Sperry Corporation und gilt neben Hermann Anschütz-Kaempfe als einer der Entwickler der ersten verwendbaren Kreiselkompasse. Sein Kreiselkompass wurde 1911 erstmals von der US-Marine eingesetzt. Insgesamt erhielt er auf einem weiten technischen Gebiet 360 Patente. Sein Sohn Lawrence Sperry beschäftigte sich ebenfalls mit der Kreiselkompasstechnik.
  • La prima bussola giroscopica di Sperry fu sperimentata nel 1910 a bordo della corazzata Delaware, ed il suo primo stabilizzatore giroscopico venne applicato nel 1913. I contributi pionieristici di Sperry in questo campo sono alla base dei sistemi di navigazione inerziale dei quali sono dotati i missili ed i veicoli spaziali. Nel corso della sua carriera, Elmer Ambrose Sperry brevettò circa 400 invenzioni e fondò otto società industriali
  • Elmer Ambrose Sperry a fost un inventator si om de afaceri american. În 1880 fondează în Chicago Sperry Electric Company, companie care se ocupa cu generatoare. Elmer Sperry fondează în 1910 Sperry Corporation şi împreună cu Hermann Anschütz-Kaempfe inventează prima busolă giroscopică. Busola sa giroscopică este utilizată în 1911 de marina americană.
