The American Philosophical Society (APS), established in 1743 by Benjamin Franklin, is the oldest learned society in the United States. Its mission is to promote 'useful knowledge' in the sciences and humanities through excellence in scholarly research, professional meetings, publications, library resources, and community outreach. The APS honors and engages leading scholars, scientists, and professionals through elected membership and opportunities for interdisciplinary, intellectual fellowship, particularly in its semi-annual meetings. It also supports research and discovery through grants and fellowships, lectures, and exhibitions at its museum.
The headquarters, Philosophical Hall, serves as the primary meeting place for Society members and hosts public lectures, events, and administrative offices. It is adjacent to the Society's Library and Museum.
Philosophical Hall is a National Historic Landmark. The complex includes Library Hall (a modern reconstruction of the Library Company of Philadelphia's original building) and Benjamin Franklin Hall, which houses a museum and event space.
The work culture is characterized by a deep respect for scholarship, history, and intellectual exchange. Staff are dedicated to preserving and promoting the Society's collections and mission, often collaborating with researchers and the public.
The headquarters' location underscores its deep historical roots in American independence and intellectual life. It has been a site for scholarly discourse and discovery for over two centuries.
While its physical campus is in Philadelphia, the American Philosophical Society maintains a global presence through its international membership, the research grants it awards to scholars worldwide, the global distribution of its publications, and digital access to its vast library and museum collections. Its meetings attract scholars from around the globe, fostering international intellectual collaboration.
