What happened
Between 1891 and 1896 the German engineer Otto Lilienthal built and flew a series of 16 different glider designs, launching first from a springboard in his own backyard and later from an artificial 50-foot hill he built near Berlin so he could launch regardless of wind direction. Over five years he made an estimated 2,000 glide flights and accumulated about five hours of total time in the air, a figure later calculated by Wilbur Wright, reaching distances up to 250 meters. On August 9, 1896, a glider stalled in the Rhinow Hills; Lilienthal fell 50 feet, broke his back, and died the next day in a Berlin hospital.
Why it matters
Lilienthal turned gliding from an idea into a repeatable, documented practice, and his photographed, published flights were studied directly by the Wright brothers, who treated his data as the starting point for their own glider experiments a few years later. His death also demonstrated that stability and control, not just lift, were the unsolved problem, the exact issue the Wrights would spend years working to fix.
How we know
Lilienthal's flights were extensively photographed at the time, one of the earliest documented uses of photography to record human flight, and his surviving 1895-96 glider is held and studied by the Museum of Flight in Seattle.
