Clément Ader
g, 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.
who invented the first aeroplane in the world The Wright brothers what are the names of the brothers? Wilbur  and Orville. what are they by profession? Aviation pioneers. did they have any formal education or degree? Both brothers attended high school, but did not receive diplomas. were the brothers in any feud with someone? Yes, with Samuel Pierpont Langley, secretary of the Smithsonian Institution. what was the feud about? Samuel Pierpont Langley, experimented for years with model flying machines and successfully flew unmanned powered fixed-wing model aircraft, but two tests of his manned full-size motor-driven Aerodrome however, were complete failures. Nevertheless, the Smithsonian later proudly displayed the Aerodrome in its museum as the first heavier-than-air craft "capable" of manned powered flight, relegating the Wright brothers' invention to secondary status and triggering a decades-long feud with Orville Wright, whose brother had received help from the Smithsonian when beginning his own quest for flight. who were their competitions? Clément Ader, Gustave Whitehead, Richard Pearse, and Karl Jatho.

Clément Ader [SEP] Electrical and mechanical inventions
Ader was an innovator in both electrical and mechanical engineering. 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.
