Born in Schiffdorf (near Bremerhafen), John Bohlen became one of Philadelphia's most prominent merchants at the turn of the nineteenth century. Running a profitable concern in partnership with his brother Bohl (1754-1836), John Bohlen imported commodities from their native Holland. Thanks to an insatiable American thirst for gin, Bohlen amassed an immense fortune that enabled him to travel in the same social circles as Stephen Girard and others among the mercantile elite and to win a spot in 1816 as one of the Directors of the Bank of the United States. By the time of his death, he was one of only eleven Philadelphians whose personal estates exceeded one million dollars in value. The Bohlen Collection contains a scant ten letters that appear to have been retained, as much as anything, for their autograph interest. Although they shed relatively little light on the life of John Bohlen, they do offer interesting glimpses into the personalities of Bohlen's famous correspondents, including Stephen Girard, Francis Scott Key, Meriwether Lewis, Virgil Maxcy, Oliver Hazard Perry, and Timothy Pickering.

This collection of letters, while tiny, is actually quite rich in content. Cadwalader wrote to Samuel Meredith, a politician and fellow Revolutionary War soldier, concerning the war, his real estate holdings in Philadelphia, and the local political climate. The seven items are dated from October 5, 1779 to March 9, 1798, during which Cadwalader served in the military, reentered politics, got married, and then retired from public service.

This volume contains letters relating to the purchase and shipment of goods in America, Europe, and the West Indies, commecing 22d, 12mo. 1744, ending 6th, 2mo. 1747. Some are signed by Matthias Aspden, John Reynell, and John Smith.

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.

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.

This collection includes four letter books (1750-1767), containing principally business correspondence with Benjamin Franklin (42 letters), William Strahan (193 letters), and the stationers Bloss & Johnson, London, Johnson & Unwin, London, and Hamilton & Balfour, Edinburgh. There are also accounts current, 1748-1768 (2 vols.), of which one contains Edinburgh. There are also accounts current, 1748-1768 (2 vols.), of which one contains Franklin and Hall's account for printing done for the province of Pennsylvania, 1756-1767, with an index volume to these accounts; records of bills of exchange remitted to London, 1745-1752 (1 vol.); there are about 90 loose letters (some are photocopies) mainly from William Strahan to Hall, 1745-1775, concerning business matters, as well as English and American politics. Included in this group is correspondence relating to Hall and his publishing partnership, and his son William's partnership with Sellers. One additional volume is a photocopy of Franklin and Hall's "Work Book No. 2," 1759-1766, 1782-1789, from the original at the New York Public Library (B H142.lf).

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.

This collection is primarily correspondence, accounts, bills, and receipts of Anthony Morris, but also included is older material on the Morris family (deeds, indentures, etc.). The correspondence centers on two major topics: the settlement of the estate of a Baron de Kalb, and information concerning Morris' proposal to set up the Fellenberg Institution for agricultural education, on his estate at Bolton Farm in Bucks County, Pennsylvania.

This collection includes letters, diaries, notebooks, and early photographs, relating primarily to the Wister family of Germantown and Philadelphia. Much of the correspondence concerns domestic news and consists of letters from or to Sarah Wister. These include interesting observations on Germantown and Philadelphia society from other families as well, such as the Bayntons and Bullocks. There are numerous letters from various Wisters, including Casper, Charles Jones, Elizabeth (including a journal of a trip to Bristol, 1783), Hannah, John, Owen Jones, and others. There is also poetry by Sarah.

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.

A leading national opinion maker and influential regional politician, tied by marriage to the families of Benjamin Franklin and cognate families, William Duane (1760-1835) played key roles in the field of political journalism, as well as national, Pennsylvania and local Philadelphia politics. Editor of the Aurora, William Duane (1760-1835) assured himself gratitude from Jefferson and the Republicans and enmity from President Adams and the Federalists for his open and effective attacks on Federalist policies. His son William John Duane (1780-1865), was a prominent member of the Pennsylvania legislature, a legal advisor to Stephen Girard, Solicitor for many of Philadelphia's premier institutions, and Secretary of the Treasury of the United States (June-September 1833). The Duane Family Collection contains a diverse assemblage of personal and professional correspondence relating to family members, with interesting material relating to William Duane (1760-1835), his son, William John Duane (1780-1865), grandson William Duane (1808-1882), great-grandson Charles Williams Duane (1837-1915), and other relations. The collection includes unique correspondence from and relating to Benjamin Franklin's family, as well as correspondence with Thomas Jefferson and other leading figures from the early nineteenth century. The collection also includes prints, photographs of family members, as well as some maps.

The Peale family is best known as a family of artists; however, family interests and activities were much more wide-ranging. The best known Peale is Charles Willson Peale (1741-1827, APS 1786), who produced more than one thousand paintings, including hundreds of portraits of leading Americans during the colonial and early national periods. Peale was married three times, to Rachel Brewster (1744-1790), Elizabeth de Peyster (1765-1804), and Hannah More (1755-1821). He had eighteen children, eleven of whom reached adulthood. Three of Charles Willson Peale's sons became artists: Raphaelle Peale (1774-1825), Rembrandt Peale (1778-1860), and Rubens Peale (1784-1865). A fourth son, Titian Ramsay Peale (1799-1885, APS 1833), was a naturalist (who made drawings on the exploring expeditions he accompanied) and pioneer in photography, and another son, Benjamin Franklin Peale (1795-1870), became a naturalist and paleontologist. Peale's daughter Sophonisba Angusciola was married to Coleman Sellers (1781-1834), an inventor and manufacturer of machinery, including locomotives. Two of their sons, George Escol Sellers (1808-1899) and Coleman Sellers (1827-1907, APS 1872), were inventors and engineers. The latter served as director of the construction of the hydro-electric power development at Niagara Falls. He was married to Cornelia Wells Sellers (1831-1909). One of their grandsons was Charles Coleman Sellers (1903-1980, APS 1979), a librarian and historian and the author of several studies of the Peale family, including a Charles Willson Peale biography.

John James Audubon (1785-1851), the American Woodsman, is a legendary naturalist and bird artist. His technique of painting North American birds dramatically as they appeared in their natural habitat was a major contribution to the emerging discipline of ornithology in the nineteenth century. His masterpiece, The Birds of America (1827-1838), elephant folio, was followed by a companion text edition, Ornithological Biography (1831-1849), a smaller octavo edition of Birds (1840-1844) and The Viviparous Quadrupeds of North America, published posthumously. This collection of original letters of publication information, ornithology, and some personal notes was sent primarily to Lucy Bakewell Audubon, his wife, from 1826-1834, and to Victor Gifford Audubon, his son, from 1833-1834, 1840-1844, with some sporadic contact with both between 1836-1839. Items in the collection relate to Audubon's Florida, Great Egg Harbor, and Great Pine Forest expeditions but not to his final expedition up the Missouri River. Of particular note, letters of 1833 and 1834 contain references to his response to the Academy of Natural Sciences of Philadelphia president George Ord's attacks on his credibility. A partial journal entry from New Orleans in 1821 and a few letters to other correspondents, including John Bachman, round out the material.

James Burd (1726-1793) was well-known in colonial Pennsylvania through his role in the French and Indian War, as well as his connections to many of the colony's leading families (most notably the Shippen family). Initially starting out as a merchant in Philadelphia, Burd became increasingly involved with colonial affairs after moving to Lancaster County with his family in 1752. It would be on the frontier where Burd would make his mark first as a soldier, and later as a magistrate. The Burd-Shippen Papers consist mainly of letters and business documents sent to James Burd, with the bulk of the collection relating to the French and Indian War, 1754-1763, in which Burd served as an officer commanding troops at Fort Augusta and elsewhere. The collection reflects all aspects of Burd's life in Pennsylvania as a merchant, soldier, and magistrate; as well as his involvement with the Shippen family professionally and personally. Intermixed with items sent to Burd are receipts to his wife Sarah Shippen Burd, and correspondence between Edward Shippen and James Hamilton regarding land matters and Indian affairs in Lancaster.

A pioneer in ethnographic and linguistic studies of the American Indian and one of the most active members of the American Philosophical Society, Peter Stephen Du Ponceau helped to establish the American Philosophical Society's reputation as one of the world's foremost centers for the study of American Indians and their languages. The Peter Stephen Du Ponceau collection consists of correspondence on legal matters, Indian linguistics, silk culture, maritime law, the American Philosophical Society, and various publications of the early nineteenth century. The collection also includes several essays by Du Ponceau, most of which deal with maritime law.

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.

Personal and professional correspondence of the chemist Robert Hare, including drafts of letters to editors of journals on such varied topics as fish guano, slaughterhouses, paper money, and the meaning of the term "Yankee annexations." The collection originally contained over 300 scrolls, since disbound, which contained drafts of letters, essays, and lectures, composed by Hare on ordinary sheets of paper, then pasted end to end, and rolled up. The essay and lecture topics include: chemistry, storms, slavery, currency, fire-fighting, capital punishment, railroads, the Smithsonian Institution, Michael Faraday, religion and Spiritualism, riots in Philadelphia, epidemics, underwater blasting, and Ralph W. Emerson; there is some verse. The collection also contains an account book of Hare and his wife, 1806-1829 (180 pp.; B/H22#3); a volume by Hare on Cyclones (tornadoes), n.d. (ca. 60 pp.; B/H22#4); and Samuel Powel, Jr.'s "Short notes on a course of antiquities at Rome... under M. Byre Antiquarian," 1764. (60 pp.).

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.

In addition to family and business correspondence, the Charles Nicoll Bancker Family Papers contains various documents, such as a furniture inventory volume (30pp.); a Daybook, 1795-1800 (120pp.); and a very interesting journal (unidentified, but by one of the Banckers, and filed under "Description of a trip..."), from New York to Albany and back, between July 20-Aug. 15, 1793 (1 vol., 31 pp.). It contains detailed observations of the Hudson River and the towns along the way. Bancker was involved in business and trade prior to 1826, and in insurance after that date, so there is material relating to those topics in this collection. He owned a substantial library of the period, which was used by Charles Wilkes's Expedition after 1837 (see Reynell Coates to Bancker). This library, along with Bancker's notable scientific instrument collection, was sold after his death and there are published auction catalogues in the collection. There is much family correspondence from: Anne E. Bancker, Charles Gerard Bancker, Evert Bancker, Sarah U. Bancker, Violetta Bancker Talbot, Elizabeth Bancker Teackle, and John Teackle.
