Otto Lilienthal — German Aviator born on May 23, 1848, died on August 10, 1896

Otto Lilienthal 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. On August 9, 1896, his glider stalled and he was unable to regain control. Falling from about 15 m, he broke his neck and died the next day, 10 August, 1896... (wikipedia)

To invent an airplane is nothing. To build one is something. But to fly is everything.
