As of July 6th, APS offices are open to staff and invited visitors. The Society will remain closed to the public for at least the rest of the summer. Library & Museum staff now have access to our collections and will respond to reference and photoduplication requests as soon as possible. However, please note that response times may be delayed due to increased demand. The Society will continue a robust slate of virtual programs throughout the summer and fall. Read more about virtual programming and resources that can be accessed remotely. For further information on the APS reopening and its COVID response, please click here.

About the APS

Old building

The American Philosophical Society, the oldest learned society in the United States, was founded in 1743 by Benjamin Franklin for the purpose of “promoting useful knowledge.” In the 21st century we sustain this mission in three principal ways. We honor and engage leading scholars, scientists, and professionals through elected membership and opportunities for interdisciplinary, intellectual fellowship, particularly in our semi-annual Meetings. We support research and discovery through grants and fellowships, lectures, publications, prizes, exhibitions, and public education. We serve scholars through a research library of manuscripts and other collections internationally recognized for their enduring historic value. The American Philosophical Society’s current activities reflect the founder’s spirit of inquiry, provide a forum for the free exchange of ideas, and convey our conviction that intellectual inquiry and critical thought are inherently in the best interest of the public.
