Joseph Rodolphe Mathieu (10 July 1890 - 29 June 1962) was a Canadian composer, pianist, writer on music, and music educator. The Canadian Encyclopedia states, "Considered too avant-garde for his time because of Debussy's influence on his music, Mathieu gained recognition too late to inspire the generation that followed." The pianist Léo-Pol Morin was one of the few important exponents of his work, notably including Mathieu's Chevauchée and Trois Préludes in his concert repertoire. Mathieu's song Un peu d'ombre (1913) was included in a number of recitals given by Marguerite Bériza and Sarah Fischer in Europe.
