Lawrence Sperry Aircraft Company.

In 1915 Elmer Sperry's son, Lawrence, was put in charge of the Sperry Gyroscope Company's Aviation Department. Two years later, Lawrence founded his own company, the Lawrence Sperry Aircraft Company, to develop and market the airplane stabilizer, aerial torpedo, and automatic pilot. Lawrence was a daring test pilot and his exploits in the 1916 Paris Air Show provided both his company and Sperry Gyroscope with valuable publicity. After Lawrence Sperry died in a December 13, 1924, flight across the English Channel, the rights to the aeronautical instruments developed by Elmer and Lawrence Sperry reverted to the Sperry Gyroscope Company.
