November 13, 1907: French Engineer Paul Cornu With His Primitive Helicopter.

Bicycle or helicopter?

The inventor conceptualized the device as a “flying bicycle,” with the hope of winning 50,000 Francs in a design contest. The history books would remember it as the first helicopter to take flight.

Like the Wright Brothers, French engineer and inventor Paul Cornu was a bicycle maker who dreamt of flight. Cornu was one of thirteen children born to the owner of a transport company, who eventually converted his business to mechanics and bicycle workshop to nurture the talents of his gifted son.

On November 13, 1907 Cornu presented his primitive helicopter, known today as the Cornu helicopter.  The Cornu helicopter is reported to have made a number of short hops, flying for about 20 second and rising about one foot off the ground. Many engineers doubt that this actually occurred and question whether flight with this invention was technically feasible. Still, many historians consider the Cornu helicopter as the first successful helicopter flight in aerial history.

Cornu published the technical details of his “flying bicycle” in a 1908 article for L’Aerophile newspaper .
