Dirigible Craft Steering Sperry Gyroscope Company Inc. Original Patent Lithograph 1932
On this original linen-backed lithograph from 1932 (includes original specification sheet), Sperry Gyroscope Company Inc. patented improvements relating to the steering of dirigible craft. The company was founded in 1910, as the Sperry Gyroscope Company by Elmer Ambrose Sperry to manufacture navigation equipment, chiefly his own inventions—the marine gyrostabilizer and the gyrocompass at 40 Flatbush Avenue Extension in Downtown Brooklyn. During World War I the company diversified into aircraft components including bomb sights and fire control systems. In their early decades, Sperry Gyroscope and related companies were concentrated on Long Island, New York, especially in Nassau County. Over the years, it diversified to other locations.
