Rare Declaration of Independence Discovered at APS
APS staff and consultants have just authenticated a copy of the Declaration of Independence from the Society's collections as the eighth known paper copy printed from engraver William J. Stone's plate.
Philosophical Hall, adjacent to Independence Hall, has been the home of the American Philosophical Society since 1789. In its Museum, visitors will see exhibitions drawn from the Society’s renowned collections that trace American history and science from the Founding Fathers to the digital age.
The American Philosophical Society is the oldest learned society in the United States. Founded by Benjamin Franklin in 1743, it continues its mission of "promoting useful knowledge" through research, fellowships, and public outreach.
