Robert Marcel Casadesus was a celebrated French pianist and composer, born on 7 April 1899 in Paris. Coming from a remarkable musical family, he studied at the Conservatoire under the guidance of Louis Diémer. There, he won several prestigious awards, including the Premier Prix in 1913. Casadesus was deeply influenced by his uncle, Lucien Capet, a prominent quartets leader, which sparked his love for chamber music.

In 1922, he began working with famous composer Maurice Ravel, and they performed together across Europe. Casadesus married pianist Gaby L’Hôte in 1921, and they often played as a duo. As a teacher at the American Conservatory during the war, he influenced many students. His last major work, Symphony No. 7, was completed shortly before his death on 19 September 1972. Renowned for his delicate style, Casadesus excelled in interpreting the works of Mozart and left a lasting legacy in the world of classical music.
