In 1877, Enrico Forlanini developed an unmanned helicopter powered by a steam engine. It rose to a height of 13 meters, where it remained for some 20 seconds, after a vertical take-off from a park in Milan. That exuded a lot of good engeenering.
Paul Cornu's helicopter, built in 1907, was the first flying machine to have risen from the ground using rotating wings instead of fixed wings.
The first time a manned helicopter is known to have risen off the ground was in 1907 at Cornu, France. The first successful rotorcraft, wasn't a true helicopter, but an autogyro invented by Spanish engineer Juan de la Cierva in 1919. These kind of rotorcrafts were culled to use until the development of modern helicopters, when, for some reason, they became largely neglected, although the idea has since been resurrected several times. Since the first practical helicopter was the Focke Achgelis Fw 61, the autogyros golden age only lasted around 20 years.
