Boulanger, Nadia. (1887 - 1979). [Thibaud, Jacques. (1880-1953)]. Autograph Letter to Thibaud re Cortot. Autograph letter on both sides of small page (3.5 x 5 inches), written in pencil and signed by the influential French composer, conductor and pedagogue, teacher of many of the 20th century's most important musicians and composers. Addressed to the violinist Jacques Thibaud, in French, relaying a message from "our dear Cortot" [the pianist, Alfred Cortot] that "he accepts the invitation to perform the 2nd Sonata at the SMI Society founded by Fauré, on either the 21st or 28th of May, and will be happy if you will accept also." Usual folds, edges a little rough, overall fine. A charming note, linking three of the major forces in French music of the 20th century.
