The Dietrich American Foundation was established in 1963 to collect, research and document historically important examples of American decorative and fine arts, primarily of the eighteenth century. The Foundation's collections comprise furniture, silver, ceramics, including Chinese export porcelain made for the American market, Pennsylvania German decorative arts, historical documents, manuscripts, prints and paintings. Other fields of interest are military and naval history, American maritime industries, with an emphasis on whaling, maps, depictions and writings concerning American Indian tribes and the exploration of the West. The holdings are made available for long-term and special-exhibit loans to a variety of museums and public institutions across the country. Many of the Foundation's objects are on view in the American Wing and Period Rooms at the Philadelphia Museum of Art in Philadelphia, Pennsylvania. The Foundation is not a grant-making organization.
