About Clément Ader
Clément Ader was a French inventor and engineer who was born near Toulouse in Muret, Haute-Garonne, and died in Toulouse. He is remembered primarily for his pioneering work in aviation. In 1870 he was also one of the pioneers in the sport of cycling in France. Using the studies of Louis Pierre Mouillard (1834–1897) on the flight of birds, he constructed his first flying machine in 1886, the Ader Éole. In 1909 he published L'Aviation Militaire, a very popular book which went through 10 editions in the five years before the First World War.
