Paul Marie Théodore Vincent d'Indy was a French composer and teacher. His influence as a teacher, in particular, was considerable. He was a co-founder of the Schola Cantorum de Paris and also taught at the Paris Conservatoire. His students included Albéric Magnard, Albert Roussel, Arthur Honegger, Darius Milhaud, Yvonne Rokseth, and Erik Satie, as well as Cole Porter.

The Schola Cantorum de Paris is a private conservatory in Paris. It was founded in 1894 by Charles Bordes, Alexandre Guilmant and Vincent d'Indy as a counterbalance to the Paris Conservatoire's emphasis on opera.
