Wanda Landowska was a Polish keyboardist, composer, and teacher best known for revitalizing harpsichord performance in the twentieth century. Her school at Saint-Leu-la-Foret, founded in 1925, became one of the great centers for the collection, study, and performance of Baroque music until it was looted by the Nazis in 1940. The collection consists of annotated music, correspondence, business papers, writings, programs, photographs, and other materials that document the legacy of Landowska. These materials largely reflect the activities and music library of Landowska and her pupil, Denise Restout, after their migration to the United States in 1941. Only the container list for the music materials is available online at this time.
