Clément Ader (1841 - 1925) was a French engineer, known for disputing with the Wright brothers and the Brazilian Santos Dumont the paternity of one of the most revolutionary inventions of the 20th century: the airplane.

The only child of a family of carpenters and a brilliant student, Clément Ader graduated early in engineering and made his fortune with his first inventions: he improved the telephone system invented by the American Graham Bell, perfected the microphone and invented the theaterphone.

From 1890, he invested part of his money in the construction of three motorized airplanes. He would have traveled with the first of them, the Eole, on October 9, 1890, about 50 meters at a height of 20 cm. But there is controversy over the stability of that first flight, which had few observers. Then, with the support of the French army, Clément Ader worked on perfecting the plane (word he invented) for 7 years, in complete secrecy.

In 1903, news reached Europe that flight experiments had been successfully carried out in the United States by the Wright brothers. Nowadays, almost all countries in the world recognize that the Wright brothers invented aviation, mainly because the duo managed to make controlled flights, at a certain point, precisely defining the main aerodynamic and piloting laws of an airplane.

On January 6, 1906, Alberto Santos Dumont also managed to make a heavier-than-air machine fly from the ground in Paris. That flight, with the 14 Bis, was an event observed by hundreds of people and officially registered, for the first time in history.

Here we have an original book and dedication by Clément Ader, one of the three main aviation pioneers.
