This correspondence is chiefly of a personal nature between Short and Alexandrine Charlotte de Rohan-Chabot, the Duchesse de La Rochefoucauld, concerning his desire to marry her and bring her to America. The Duchesse's letters describe life in a powerful, wealthy, and noble French family under the ancien régime, including events of the Revolution and the Reign of Terror, and life in France thereafter. The collection also includes letters from Lafayette, Count Luigi Castiglioni, Pauline Castiglioni, and the Duc de La Rochefoucauld-Liancourt.

Written from China to his family, the letters of James Bancker contain descriptions of the social life of the Americans and English in China, of Hong Kong after the British acquisition of that place, and of anti-British riots in Canton. A long letter describes the outward voyage from New York to Canton; several letters given an account of a visit to the Philippines; and there is a partial journal of Bancker's return home through the Red Sea.

The son of William Franklin, Royal Governor of New Jersey, William Temple Franklin worked as aide to his grandfather, Benjamin Franklin, when the latter served as minister to France during the American Revolution. A bonvivant, Temple received his highest public appointment as Secretary to the American delegation at the Treaty of Versailles in 1782-1783, largely through the influence of his famous grandfather, but never again attained a significant post. As Franklin's literary heir, he edited and published a three volume set of his grandfather's writings in 1817. He married his long time mistress a few months before his death in Paris in 1823. The William Temple Franklin Papers provides a richly detailed portrait of the life of the grandson of Benjamin Franklin, and consists largely of letters received during the years that Temple served as his grandfather's aide in France, 1776-1785. Although much of the correspondence is routine, during this period, Temple received regular reports from friends and diplomatic colleagues relaying information on the American Revolution, the course of diplomatic and peace negotiations, and French public opinion on Benjamin Franklin and the new United States. The collection is also a rich resource for information on the personal lives of the Franklins, including interesting correspondence from Temple's relatives William Franklin, Elizabeth Franklin, Sarah Franklin Bache, and Jonathan Williams, and his mistress Blanchette Caillot.

The only son of Benjamin Franklin, William Franklin served as Royal Governor of New Jersey during the critical years between 1762 and 1776. An ardent Loyalist, William split with his father over their political differences in the early days of the Revolution, and after enduring two years of imprisonment, became a leader in the Loyalist cause. He settled in London in 1782, where he worked as an agent for Loyalist claims. The William Franklin Papers are a miscellaneous assemblage of letters and documents, dealing largely with Franklin's years as Royal Governor of New Jersey. The majority of the letters are perfunctory, however they provide some information on Franklin's land holdings in New Jersey and the Ohio country. The collection includes two letters relating to Franklin's imprisonment in Connecticut during the Revolution, two affectionate letters to his sister Sarah, and one to his son William Temple Franklin.

The collection contains information on Fox family speculation in western lands, two manuscript maps from the 1790's and 1830's depicting the family's holdings in northwestern Pennsylvania, and a photograph album from the 1890's documenting Chestnutwold, the Fox estate adjacent to Andalusia. Chief correspondents are Samuel and George Fox.

An important 18th century radical republican theorist and political writer, Thomas Paine was a leading figure in the American Revolution. Despite his humble beginnings and lack of formal education, his reasoned and persuasive writings not only influenced nascent American republican ideology, but profoundly affected the perception of government in England and France as well. His three most influential works are Common Sense (1776), The Rights of Man (1791-1792), and The Age of Reason (1794, 1795, 1807). The Richard Gimbel Collection is a heterogeneous mix of items connected only by the fact that they were all collected by Gimbel (1898-1970) and that most were written by, to, or about the revolutionary Paine. Of primary importance are the approximately sixty-five letters or manuscripts in Paine's own hand, including Paine's 1776 manuscript notes for Common Sense, his letter of January 10, 1781, in which he takes leave of his former commanding officer, Nathanael Greene, and his January 6, 1789 letter to Kitty Nicholson Few, in which he writes of his view of matrimony and other personal matters. The collection includes a series of correspondence between Thomas Paine and Samuel Adams, which were originally marked "forgeries," these appear instead simply to be the letters of two men bearing famous names.

The collection includes letters between Hutchinson and his uncle Israel Pemberton, written while Hutchinson was a student of medicine in London. There are also 12 tickets of admission to medical lectures in Philadelphia and London, including one given by William Hunter, and 3 unused cards of admission to Hutchinson's own lectures. Miscellaneous items include Hutchinson's marriage certificate; genealogical data on the Hutchinson, Hare, and Pemberton families; and stock certificates, 1857-1872, of the McKean and Elk Land and Improvement Company. Materials dated post-1793 are to and from Hutchinson family members.

The Calendar of the Papers of Benjamin Franklin prepared by Isaac Minis Hays for the bicentennial of Franklin's birth in 1906 provides access to the largest portion of the Franklin Papers at the APS. The items were originally bound into volumes in roughly chronological order, with letters to Franklin preceding those from Franklin and at the end of the collection, Franklin's letters owned by the University of Pennsylvania. Each manuscript is still identified by Hays' reference numbers, which include a roman numeral refering to the original volume followed by an arabic number to identify the folio. The electronic version of the finding aid replicates Hays' calendar, including the introductory material and item-level descriptions. It has been updated to reflect corrections in the metadata, corrections of personal names, dates, and description.

These letters and papers include ten small volumes of letterbooks (1752-1781), and ca. 100 pieces of correspondence with Joseph Shippen (1750-1778). Topics discussed are business in Philadelphia and Lancaster, provincial politics, army supply in the French and Indian War, land purchases and speculation, housebuilding, and family affairs.

The most stellar member of a stellar family, Elisha Kent Kane was among the most popular American explorers of the mid-nineteenth century, a hero in the tragic mode. Born in Philadelphia in 1820, the son of John Kintzing Kane and Jane Duval Leiper, Kane studied medicine at the University of Pennsylvania before earning a commission as a naval surgeon. While in the Navy, Kane embarked on the succession of voyages to exotic locales that became the basis for his extraordinary fame. In 1843, he attended Caleb Cushing's first diplomatic mission to China as ship's physician, and subsequently traveled to the Philippines and Western Africa. Distinguishing himself in the Mexican War, Kane's greatest fame came from two expeditions to the arctic, aiming to locate the lost explorer, Sir John Franklin and to explore for evidence of the open polar sea. Kane died in 1857 while attempting to organize a third arctic voyage. Part of the Kane Family Collection, the Papers of Elisha Kent Kane contain a mix of personal and family correspondence with correspondence relating to all of Kane's explorations. Intelligent, articulate and very much a romantic, Kane's letters are expressive and passionate. The collection provides fine documentation of youth, his relationship with the Spiritualist Margaret Fox, and of course his travels to China and off the coast of Africa in 1846. Kane's two expeditions to the arctic are particularly well documented, with correspondence, notes, logbooks, diaries, and sketches, as well as Kane's post-expedition notes, writings, and lectures recounting his experiences.

After a brief career in the Congregational church, J. Peter Lesley (1819-1903) left the ministry in 1852 to work full-time as a geologist. Having gained experience in structural geology and stratigraphy with the First Pennsylvania Geological Survey (1836-1842), Lesley became an expert in the geology of coal, working for the Pennsylvania Railroad and other corporations and conducting some of the first systematic studies of the state's hydrocarbon resources. A long-time professor at the University of Pennsylvania, he was elected to the APS in 1856, serving variously as its librarian, secretary, and vice president, and he was selected as Director of the Second Pennsylvania Geological Survey (1875-1889). The Lesley Papers include letters to and from Peter Lesley and his wife, Susan on geology, coal and iron mining, abolition, educational reform, organized charity, and Unitarianism. The collection offers important insight into academic and applied geology in late 19th century Pennsylvania, the development of the coal and iron industries, as well as into the Lesleys' progressive social and intellectual milieu. It is divided into three series: Lesley's general correspondence, his correspondence with his brother Joseph, and microfilms of Lesley's research notes.
