Clément Ader (2 April 1841 – 5 March 1925) was a French inventor and engineer born in Muret, Haute Garonne, and is remembered primarily for his pioneering work in aviation.
Ader was an innovator in a number of electrical and mechanical engineering fields. He originally studied electrical engineering, and in 1878 improved on the telephone invented by Alexander Graham Bell. After this he established the telephone network in Paris in 1880. In 1881, he invented the "théâtrophone", a system of telephonic transmission where listeners received a separate channel for each ear, enabling stereophonic perception of the actors on a set; it was this invention which gave the first stereo transmission of opera performances, over a distance of 2 miles (3 km) in 1881. In 1903, he devised a V8 engine for the Paris-Madrid race, but although three or four were produced, none were sold.
Following this, he turned to the problem of mechanical flight and until the end of his life gave much time and money to...
