At the American Philosophical Society 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. Holdings include over 2.5 miles of manuscript pages and approximately one million rare books, prints, photographs, paintings, scientific instruments, Native American language recordings, and other objects.

Past exhibitions have featured items such as Thomas Jefferson’s hand-written draft of the Declaration of Independence, a notebook from Lewis and Clark’s Western exploration, a rare 18th-century telescope, Darwin’s hand-written title page for On the Origin of Species, and the only known portrait of Benjamin Franklin’s wife Deborah.

Each exhibition offers imaginative programs that interpret the historical themes and objects on view and connect them to relevant issues in the world today.

APS Museum exhibitions are open to the public every year from mid-April through December, Thursdays through Sundays.
