The archives collection chronicles the organization and activities of the Society of the Cincinnati from its founding in 1783 to the present. The early documents, covering the period from 1783 through the early 1930s, are accessible to researchers and provide a wealth of information on the history of the Society and related topics in American history, such as compensation for Revolutionary War veterans and widows, public views of military officers and hereditary organizations, early French-American relations, and nineteenth- and twentieth-century remembrances of the Revolutionary War. Highlights of the historical archives include the original Institution of the Society, early minute books, and manuscript correspondence of prominent original members such as George Washington, Henry Knox, and Pierre L’Enfant. The archives also include L’Enfant’s original drawings for the Society’s emblems of membership and the original copper plate used for printing the Society diploma he designed. More modern materials in the archives include records from the late nineteenth century through the present regarding the Society’s activities, such as minutes, correspondence, rosters, programs, menus, and photographs of Society events.

From its earliest meetings, the Society took great care in organizing its official records, commissioning a special mahogany box in 1787 to house and protect them. For more than a century, the growing archives collection was kept in the personal custody of the Society’s secretary general, moving from house to house until 1911, when the Society arranged to have the collection housed with the Lincoln Safe Deposit and Storage Company in New York City. In 1930, the archives were placed on deposit at the Library of Congress, where they were made available to researchers and microfilmed. After the establishment of the library in the Society’s headquarters at Anderson House, the archives were returned to the Society’s care in 1973.

The early archival collection is described in a finding aid on the digital library.
