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. On August 9, 1896, his glider stalled and he was unable to regain control. Falling from about 15 m (50 ft), he broke his neck and died the next day, 10 August, 1896.
Paul Beylich, Lilienthal's glider mechanic, transported him by horse-drawn carriage to Stölln, where he was examined by a physician. Lilienthal had a fracture of the third cervical vertebra and soon became unconscious. Later that day he was transported in a cargo train to Lehrter train station in Berlin, and the next morning to the clinic of Ernst von Bergmann, one of the most famous and successful surgeons in Europe at the time. Lilienthal died there a few hours later (about 36 hours after the crash); his last words to his brother Gustav were "Opfer müssen gebracht werden!" (Sacrifices must be made!). Otto Lilienthal was buried at Lankwitz public cemetery in Berlin.
