The Frederick Law Olmsted National Historic Site encompasses the home and office of Frederick Law Olmsted, the great American landscape architect and designer of many major nineteenth century urban parks. The park also houses the Olmsted Archives, documenting over 5,000 landscape design projects undertaken by Frederick Law Olmsted, Sr.(1822-1903), his sons, John Charles (1852-1920) and Frederick, Jr. (1870-1957), their partners and associates. Their work included numerous public parks and parkways, such as New York's Central Park, the U.S. Capitol and many state capitol grounds, school and college campuses, residential suburbs, arboretums, and private estates.
This collection represents a continuity of American landscape design by a single professional office and reflects the history of landscape architecture and environmental design in the United States. Included in the collection are plans and drawings, correspondence, financial and administrative records and reports, lithographs, planting lists, photographic prints and negatives, design models dating from the 1860s to 1980 and original office furniture and equipment. There also are study collections on urban design, landscape architecture, and the fine arts in general, and a reference collection of maps and atlases.
