Glenn Hammond Curtiss (1878-1930) is best known as an aviation pioneer and inventor and founder of the Curtiss Aeroplane and Motor Co. Initially a bicycle repairman and designer, by 1902 Curtiss had begun to manufacture motorcycles using a lightweight internal combustion engine of his own design and founded the Curtiss Manufacturing Co. By 1904, Curtiss' engine had been co-opted by Thomas Baldwin for his airship experiments. This activity led to a connection between Curtiss and Alexander Graham Bell and, in 1907, to the foundation of the Aerial Experiment Association. In 1909, Curtiss joined with Augustus M. Herring to form the Herring-Curtiss Co to manufacture powered vehicles, but Herring's unsubstantiated claims to priority over the Wright Brother's aeronautical patents led to the Wright and Curtiss patent suits which continued until the merger of Curtiss Aeroplane and Motor with Wright Aeronautical in 1929. Curtiss and Herring split after the Wright's filed suit and Herring sued Curtiss, claiming that Curtiss had failed to turn his air race winnings over to the company. Despite these, and other, suits, Curtiss continued to advance the cause and technology of aviation, founding the first public flying school (1910) and later a chain of schools across the US, inventing the aileron (1909), the dual-control trainer (1911) and the hydroaeroplane (1911). In 1920, Curtiss retired from active aviation pursuits.
