Otto Lilienthal
Otto Lilienthal (23 May 1848 – 10 August 1896) was a German pioneer of aviation who became known as the Glider King. He was the first person to make well-documented, repeated, successful gliding flights. Newspapers and magazines published photographs of Lilienthal gliding, favorably influencing public and scientific opinion about the possibility of flying machines becoming practical. He died of injuries sustained when his glider stalled and he was unable to regain control; falling from about 15 m (50 ft), he fractured his neck.
