From Wikipedia, the free encyclopedia
For the inventor of Solresol, see François Sudre (1787–1862).
François Sudre (1844–1912) was the inventor of the sudrophone, a brass instrument resembling an ophicleide in shape, and patented in 1892.[1][2]
Born in Carcassonne,[3] southern France, he was a director of Comte et Cie., which in 1873[4] or 1875[5] had acquired Halary, the instrument-maker founded by Jean Hilaire Asté in 1804, and who had patented the ophicleide in 1821.
