Description: Since 1789 this two-story late-Georgian brick building has housed America’s oldest learned society. The organization traces its origins to 1743, when Benjamin Franklin publicly urged the creation of an institution to stimulate interest in learning and useful knowledge. Today, Philosophical Hall is the location ofthe Society’s executive offices and museum gallery.  Over the years the Society has counted America’s intellectual elite among its members. Thomas Jefferson was one, and at his urging, the records of the Lewis and Clark Expedition are preserved in the Society’s Library, across the street.. The Society’s journal, Proceedings, isthe country’s longest-running scholarly publication.
