Juan de la Cierva
Cierva was born in Murcia in Spain.
He was one of the pioneers of rotary wing flight and was responsible for successfully introducing the flap hinge as a method for making rotary-winged aircraft controllable. He went on to develop many successful autogyros, or gyroplanes, with many companies purchasing licensing rights for the many patents that he developed.
He was killed in an air crash at Croydon, United Kingdom, on December 9, 1936.
