Kelly Cup

Glenn H. Curtiss built the foundation for his airplane engine fame on the knowledge and prestige he gained from building and racing motorcycles. By 1902 he and three other employees were manufacturing motorcycles under the brand name "Hercules". Due to his competitive nature, Curtiss entered in and won many races for both motorcycles and airplanes. The Kelly Cup was won by Glenn H. Curtiss for breaking world's quick starting record with an airplane, at the San Antonio Aviation Meet April 23, 1910, San Antonio, Texas.
