Clément Ader (1841 - 1925) was a French engineer, known for competing with the Wright brothers and the Brazilian Santos Dumont for 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 a fortune with his first inventions: he improved the telephone system invented by the American Graham Bell, perfected the microphone and invented the theatrephone.
From 1890 onwards, he invested part of his money in the construction of three motorized airplanes. He flew the first of them, the Eole, on October 9, 1890, about 50 meters at a height of 20 cm. However, there is controversy about the stability of this first flight, which had few observers. Afterwards, with the support of the French army, Clément Ader worked on perfecting the airplane (a word he invented) for 7 years, in the utmost secrecy.
In 1903, news reached Europe that flight experiments had been successfully carried out in the United States by the Wright brothers. Today, almost every country in the world recognizes that the Wright brothers invented aviation, mainly because the duo managed to achieve controlled flights, at one 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. This flight, with the 14 Bis, was an event observed by hundreds of people and officially recorded for the first time in history.
Here we have an original book and dedication by Clément Ader, one of the three main pioneers of aviation.
