The Frederick and Rose Plaut Papers consist mainly of negatives, contact sheets, and enlargements of photographs taken by Frederick Plaut during his years as a recording engineer for Columbia Records. Over 35,000 negatives and 3,600 enlargements portray musicians, writers, actors, artists, and diplomats, both in candid studio shots and posed publicity photos. An additional 23,000 negatives and 2,000 enlargements depict travel and miscellaneous subjects. The Papers contain books, magazines, posters, and record jackets which reproduce Plaut's photographs. The Papers also house correspondence between the Plauts and various composers, including Francis Poulenc, Virgil Thomson, Ned Rorem, and Henri Sauguet. The Plauts' life and work are documented further by exhibit announcements, recital programs of Rose Plaut, and personal papers.
