David Nadien was an American classical violinist and Mannes College of Music teacher. The collection includes programs, contracts, reviews, biographies, obituaries, awards and honors, photographs, public relations materials, a small amount of correspondence, sheet music, and a 1952 "Seasons Greetings" ceramic plate from the television variety show, "Your Show of Shows."

This collection consists of news clipping files and scrapbooks that document Mannes from its founding through the early 1990s. The scrapbooks, which cover the school's early history through the 1960s, contain concert programs, advertisements, and news articles. Other scrapbooks, some from before the establishment of Mannes, document the activities of the school's founders, David and Clara Mannes, in their work as musicians and educators.

Sylvia Marlowe (1908-1981) was an important mid-twentieth century American harpsichordist. The Sylvia Marlowe collection documents her performance career, predominantly through scores, many inscribed to her by composers. Additionally, photographs and textual publicity materials provide further context for Marlowe's performances and recordings.
