Dumbarton House's collection of furniture, paintings, textiles, silver, and ceramics, consists primarily, but not exclusively, of objects dating from the Federal period of U.S. history (approximately 1790-1830). There are a few pieces from the earlier Chippendale period, such as a large English Chippendale linen press that belonged to the Lewis-Washington family, as well as a few examples of Louis XVI French furniture, reflecting the late 18th and early 19th century taste in American. However, the works of American cabinetmakers from the New England states to South Carolina, comprise the major portion of the Dumbarton House furniture collection.

A highlight of the collection of early American paintings on display at Dumbarton House is a portrait of the children of Benjamin Stoddert, first Secretary of the U.S. Navy. The portrait was painted by Charles Willson Peale in 1791. The background scene depicts Georgetown as an early tobacco port, only 40 years after it was incorporated as a city.

The Dumbarton House manuscript and document collection includes one of five original known copies of the Articles of Confederation, as well as papers, journals, account books, ledgers and letters documenting nearly 300 years of Nourse family life. The collection is carefully stored and indexed, and documents pertaining to the Nourse occupation of the house have been transcribed.

Dumbarton House contains a collection of over 1,000 original, unique and interesting pieces, full of a rich history that is enjoyable to all. In addition to our permanent collection, we also offer a series of temporary exhibits that feature topics relevant to additional interpretation of the museum.
