Otto Lilienthal

Otto Lilienthal (23 May 1848 – 10 August 1896), the German "Glider King", was a pioneer of human aviation. He is often credited with building the first successful human-carrying glider, the Derwitzer Glider in 1891, but this distinction in fact belongs to Sir George Cayley who accomplished this feat nearly forty years previously.
