History of the Autogiro
This video, from the History Channel, is a look at the earlist history of gyroplanes and includes a brief view of their contribution to the development of helicopters.
"Autogiro" was the name given to these aircraft by Juan de la Cierva, the Spanish inventor whose first development of these aircraft were essentially an airplane with a rotor attached.
Companies in other countries adopted these aircraft, many of them licensed by de la Cierva, and continued their development, adding other innovations. Over time, the name "autogyro" became a more universal name for these aircraft. In the US, the aviation agency now called the Federal Aviation Administration (FAA) chose the name "gyroplane" for them.
