French engineer who manufactured bicycles by trade.
French engineer Paul Cornu designed the first manned rotary wing aircraft and made the first piloted free flight with it at Normandy, France on November 13, 1907. This first helicopter was powered by a 24 horsepower (18 kW) Antoinette engine. The helicopter was not maneuverable however, and the construction was abandoned after a few flights. Previously, a French helicopter, the Breguet-Richet Gyroplane I, had managed to lift off by its own power, but it had been held in position by men standing on the ground. Paul Cornu died in 1944 in Lisieux France, when his home was destroyed during the bombardment that accompanied the Normandy landings.
