John Vaughan (1756-1841) was an English wine merchant and long-time treasurer and librarian for the American Philosophical Society. He met Benjamin Franklin while in France in 1778, then came to Philadelphia in 1782 and entered the business of importing spirits into America.
Vaughan was elected to the American Philosophical Society in 1784, became its treasurer in 1791, and librarian in 1803, serving in these posts until his death. Vaughan was instrumental in building the Society's library collection and introducing many scientists and historians to each other through his letters and Sunday breakfasts. Although not a scholar himself, he appreciated their talents and contributions.
