Ader, Clement 1841-1925.
French aviation pioneer and inventor. He
demonstrated stereophonic sound transmission
by telephone at the 1881 Paris Exhibition of
Electricity. His steam-driven aeroplane, the
Eole, made the first powered takeoff in
history (1890), but it could not fly. In
1897, with his Avion III, he failed
completely, despite false claims made later.
