Answer 6

The short answer is that no one person can claim credit for the helicopter in the manner that the Wright brothers did so for the airplane.  However, certain individuals have played key roles.  Juan de la Cierva, with the development of the Autogiro, provided many of core technologies of rotary wing flight.  Many of those associated with gyroplane development deserve credit for making rotary wing flight practical, such as Bennett, Pitcairn, Larsen, Kellett, Prewitt and Hafner.  Henrich Focke, operating under the auspices of the Third Reich, did much to promote the helicopter.  In the United States, Igor Sikorsky’s perseverance in adapting Autogiro technology resulted in the adoption of the single main rotor helicopter as the conventional configuration.  Many types of helicopters had particular pioneers behind their origin, such as Arthur Young and Bart Kelly with the teetering (semi-rigid) rotor and Frank Piasecki with the tandem rotor.
