The Casadesus family is a prominent French musical dynasty whose members were active primarily in the first half of the 20th century. The family produced a number of influential performers, composers, and musicologists who contributed to classical music performance and scholarship, particularly in the realms of piano, violin, viola, and chamber music.
Origins
The family originated in the Paris region; the earliest notable members were born in the late 19th century. The surname “Casadesus” is of Catalan origin, reflecting the family’s ancestral roots in the Catalan-speaking region of Spain, though the family became fully established in France.

Collective impact
Performance: The Casadesus musicians were instrumental in promoting French piano repertoire and chamber music internationally. Recordings by Robert and Gaby Casadesus remain part of the standard discography for Mozart piano sonatas and French works by Fauré and Ravel. The Quatuor Casadesus was a leading European string quartet in the interwar period, touring extensively and premiering new works.
Composition and musicology: Henri and Marius Casadesus are noted for their “creative reconstructions” of Baroque pieces, a practice that sparked debate over authenticity in musicology. Their forgeries, while later discredited, highlighted the demand for “lost” repertoire and influenced later scholarly standards for critical editing.
Pedagogy: Members of the family held teaching positions at the Paris Conservatoire and other institutions, shaping several generations of French musicians.
Legacy
The Casadesus name continues to be associated with high‑caliber French performance practice. Their recordings are frequently reissued, and archival materials related to the family are held in French national libraries and conservatory collections. Contemporary musicians and scholars cite the Casadesus family as a central reference point for 20th‑century French musical heritage.
