The Frederick R. Koch Collection consists of musical, literary, and historical materials collected by Frederick R. Koch, principally through purchases at public auctions, 1979-1986. Including individual items, concentrations of related materials, and several extensive archives, the collection is a broad and deep resource for study of the lives and works of a range of composers, authors, and other historical figures. Most materials are music manuscripts, literary manuscripts, drawings, and correspondence of European, English, and American composers, authors, and artists. Also present are historical manuscripts, photographs, albums, and other papers. While the contents of the collection span the seventeenth to twentieth centuries, most date from the nineteenth to early twentieth centuries, with particular strengths in French, Italian, German, and British music, French literature, and British art.
