Clément Ader's Éole and Avion III
This is Avion III, an 1897 aircraft designed by Clément Ader. Ader was a French inventor and engineer, who became interested in flight after working on electrical communications and gas ballooning for much of his career. This was the second flying machine he designed. It was an updated and improved version of his first design from 1890, the Ader Éole.
