[1] Following World War II, he traveled to Paris where he studied music with Nadia Boulanger and was a friend of Douglas Allanbrook.
[3] He received numerous awards throughout his career, an award from the American Academy of Arts and Letters for his creative work in 1959, and from France, twice laureate of the Fondation de France, in 1998, the grade of Commandeur of the Ordre des Arts et des Lettres, and, in 1999, from the city of Paris, the Grand Prix de la Musique.
He was the pianist for the American violinist Paul Makanowitzki (1920-1998), the Dutch baritone Bernard Kruysen (1933-2000) and the French soprano Anne-Marie Rodde.
As a pianist, he toured on six continents and recorded 198 LPs and CDs since 1955, particularly of Schubert (including the complete sonatas), Debussy, Ravel, Charles Ives, Bartók, Stravinsky, Aaron Copland and Elliott Carter.
He was instrumental to the rediscovery of American composer Louis Moreau Gottschalk (1829–69), and his Gottshalk recording (CD Erato reissued on Warner Classics/Apex) was used in the soundtrack to the 1994 Michel Deville film Aux petits bonheurs.
