Dumbarton House is a Federal period historic house museum, ca. 1800, whose historic structure and collection are preserved to educate the public about life in Washington, D.C, during the early years of the Republic. The museum features an extensive collection of Federal-era decorative arts, paintings and furniture, and is the only fully-furnished Federal house museum open to the public in Washington. Dumbarton House serves as the headquarters of The National Society of The Colonial Dames of America (www.nscda.org), a women’s organization that actively promotes our national heritage through historic preservation, patriotic service and educational projects. The life and times of Dumbarton House resident (1804-1813), Joseph Nourse, is the interpretive focus; Nourse served as first Register of the U.S. Treasury under six U.S. presidents and is known as “America’s First Civil Servant.” Dumbarton House is accredited by the American Association of Museums. The museum hosts a variety of public events and programs, as well as private rental events.
