Vincent de Groof's Ornithopter
This is Vincent de Groof’s design for an ornithopter, built and tested in Bruges and London in the 1870’s. Details about de Groof’s life are sketchy, and newspaper articles from his day tend to contradict themselves. One consistent fact is that he was called The Flying Man. His goal was to achieve flight, and he believed it was possible for a human to fly by imitating the flight of a bird.
