Adolphe Alexandre Silvain Marty (29 September 1865 – 28 October 1942) was a French organist, improviser, composer and music educator who was blind for most of his life.
Born in Albi in the Tarn department in the south of France, Marty became blind at the age of two and a half years.
He entered the Institut National des Jeunes Aveugles in Paris in 1874 and worked the organ with Louis Lebel (1831–1888).
In 1888 Marty succeeded Louis Lebel as organ teacher at the Institut National des Jeunes Aveugles, where he taught until 1930.
His students included Louis Vierne, Augustin Barié, Paul Allix, André Marchal, Jean Langlais and Gaston Litaize.
