George Clymer was a successful merchant, well-known politician, and a generous philanthropist, but is today most famous for being a signer of the Declaration of Independence. As a proponent of independence, he joined various local political committees including six of the seven Philadelphia resistance committees. From there, he entered the national political arena and in 1776 was elected to the Second Continental Congress where he signed the Declaration of Independence. The George Clymer Collection is a small one and not reflective of his varied pursuits. There are twenty-seven documents, most of which are not signed by Clymer; those that are signed by Clymer are dated between May 3, 1800 and January 22, 1813. The items represent not Clymer's political activities but his ordinary legal and real estate transactions.

These letters are mainly business correspondence with his friend William Temple Franklin or are about Franklin's lands and investments in the United States.

Associates of Benjamin Franklin and his grandson William Temple Franklin, the Fox family of Philadelphia were holders of considerable property in Philadelphia during the eighteenth century and speculated extensively in lands in the northern and western parts of the state.

He donated the collection to the American Philosophical Society in 1840. The legal records that comprise the William Temple Frankln-Charles Pemberton Fox collection relate to real property held by members of the Fox family and to the land holdings and financial interests of George Fox's close friend, William Temple Franklin. The collection includes about 100 deeds for properties in or near Philadelphia and in Luzerne County, Pa., along with a small quantity (about 31 items) of miscellaneous correspondence addressed to George Fox by Gouverneur Morris, Robert Morris, N. Cantwell Jones, Thomas Eddy, and others; and from William Constable and Sir Robert Herries and Co. (17 pieces) relating to the investments of William Temple Franklin.
