Lawrence Burst Sperry
Lawrence Burst "Gyro" Sperry (22 Decemeber 1892–11 January 1924), son of Elmer Ambrose Sperry was an aero inventor and aviator who continued his father's work on gyroscopes stabilization. The two worked under the Sperry Gyroscope Company in Brooklyn, New York.
With Glenn Curtiss, Sperry developed a gyroscopic airplane stabilizer in 1913 for the U.S. Navy. His device used one gyroscope for vertical stability and another for horizontal. He demonstrated an airplane equipped with the stabilizer at the Concours de la Securité en Aéroplane, held by the Aero Club de France in Bezons in June 1914. Here, Sperry first flew past the judge's stand with the airplane on "autopilot" and his hands in the air. Next, he flew with no hands and his engineer Emil Cachin standing on the wing. Finally, he flew again, this time with Cachin standing on one wing and himself on the other, with the airplane maintaining a steady course.
We have Lawrence Burst Sperry at the specific address 1505 Albemarle road, Brooklyn, in the county of Kings and the State of New York and the Lawrence Sperry Aircraft Company or the Lawrence Sperry Aircraft Company, Inc. situated in New York City, NY. This is of some note in that it features Lawrence's own name and is not the Sperry Gyroscope Company founded by his father.
We have Lawrence Burst Sperry still personally addressed at 1505 Albemarle road, Brooklyn, in the county of Kings and the State of New York though appearing as the assignor to the Sperry Gyroscope Company.ref>Patent US-1918-1309489</ref>
