A mineralogist and chemist associated with the University of Pennsylvania (1822-1828), William H. Keating was a central figure in the scientific community in Philadelphia during the 1820s and 1830s. Active in the American Philosophical Society and Academy of Natural Sciences, and a founding member of the Franklin Institute, Keating was official geologist on Stephen Harriman Long's expedition to the Great Lakes in 1823 and spent three years in the late 1820s surveying the mineral resources of Mexico. The William H. Keating notebooks include three cash books (daybooks of cash expenditures, 1830-1839) and a book containing surveys of Keating lands in Potter County, most undertaken by Silas McCarty for William's father John Keating (1801-1818). The surveys associated with John Keating are an interesting record of land investment and speculation in the northern tier of Pennsylvania. William Keating's meticulous cash books provide a detailed record of his domestic expenses, philanthropic involvements (donations to the Catholic Church, the Prison Society), his reading (newspapers and books are listed individually), socializing (theatre tickets, Assembly fees), and a variety of miscellaneous expenditures ranging from purchase of a lithograph of Dugald Stewart to a table lamp from C.

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.

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. The son of Dr. George Fox, Charles Pemberton Fox inherited the estate Champlost at which the papers of Benjamin Franklin were left in 1790. 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.

After William Temple Franklin returned to Europe in 1792, he left oversight of his financial interests in America in the hands of his intimate friend and fellow land speculator, George Fox. A physician and member of the American Philosophical Society, Fox also took possession of the remainder of Benjamin Franklin's papers, which eventually passed through his son, Charles Pemberton Fox, to the APS. The Franklin-Fox Collection contains 98 items, consisting mostly of letters from William Temple Franklin to George Fox regarding land holdings and finances, and retained copies of Fox's letters to Franklin. The correspondence is fairly relentlessly focused on business matters and rarely contains personal comments, however there are occasional requests for books and two reference to the yellow fever epidemic of 1798 and the death of Benjamin Franklin Bache.
