Marcel Dupré , French organist and composer (1886-1971) grew up in a family of musicians - his two grandfathers were organists and chapel masters, his mother pianist and cellist, his father holding the Saint-Ouen organ in Rouen . He studied at the Paris Conservatoire with L. Diemer, A. Guilmant, L. Vierne and Ch.-M. Widor, and won First Prize piano, organ, fugue, as well as the Prix de Rome in 1914. His career as a virtuoso organist took off when he performed, in 1920, all the work of Bach memory - in 1953, he had given 1900 concerts around the world. He succeeded Widor in 1934 at the tribune of Saint-Sulpice, which he kept until his death. Professor at the Conservatoire de Paris since 1926, he formed a pleiad of students among whom we can name O. Messiaen, J. Langlais, J. Alain, P. Cochereau, R. Falcinelli, M. Cl. Alain, M. Chapuis, J. Guillou, O. Pierre.
