A New Hampshireman and one of the most famous military figures in colonial America, Robert Rogers saw brief service in the militia during King George's War, but found fame as a commander of rangers during the Seven Years War. An efficient leader and crack woodsman, Rogers gained a hard driving reputation in leading his rangers against the Abnaki Indians at St. Francis Quebec, and for service at Quebec, Montreal, Fort Pitt, and Detroit. After voyaging to England in 1765 to advance his career, he was appointed to the command of Fort Michilimackinac at the tip of the southern peninsula of Michigan, but was recalled less than two years later for impropriety and suspected treason. He later offered his services to George Washington before serving in the Loyalist Queen's Rangers. As Commander of Fort Michilimackinac from 1766-1768, Rogers sat at the critical nexus of the British fur trade, the point connecting the vast interior of the western Great Lakes and northern plains to the trading centers at Montreal and elsewhere in the east. His "Estimate of the Fur and Peltry Trade in the District of Michilimackinac, according to the bounds and limits, assign'd to it by the French, when under their government: together with an account of the situation and names of the several out-posts" is, as the title suggests, an overview of this most important area of economic activity. Rogers gave this manuscript to Jonathan Carver (the man he has sent on an expedition to find the Northwest Passage), who relayed it to Thomas Barton of Lancaster, Pa., who, in turn, sent it to the American Philosophical Society. It was received at the APS and referred to the Committee on Trade and Commerce on December 20, 1768.

There are letters, petitions, and reports concerning the Loyalists and the losses they sustained in the Revolutionary War. Includes the Committee of American Merchants, Observations on trade (1783), Banished American merchants petition (1789), and Classes of American loyalists and their claims.

Between 1764 and 1781, the Scots surveyor George Gauld was assigned by the British Admirality to chart the waters of the Gulf Coast off British West Florida, an area that extended from New Orleans to the modern-day Florida. In 1773, Gauld submitted some of his findings to the APS, probably in hopes of having them published in the Transactions, and although these were not published, they became one of the first mansucripts entered into the Society's collections. Contains occasional brief references to Native peoples of the areas described. The Gauld manuscript also includes an extract of a letter from John Lorimer to Gauld, 1772, and a sketch of the Middle and Yellow Rivers of West Florida by Thomas Hutchins. When it was received at the APS, it was endorsed: "This long uninteresting Paper can hardly obtain a Place in the Transactions of a Philosophical Society. It should however be preserved in the Files for the Use of Historians or map makers."

Correspondence from Charles Mason and Jeremiah Dixon to Thomas Birch, and Nevil Maskelyne to Charles Mason, relating to the survey, and the transits of Venus (1761,1769).

David Rittenhouse (1732-1796) was one of the most prominent American men of science of the 18th Century. A skilled instrument maker, Rittenhouse was the an astronomer, playing a major role in recording the 1769 Transit of Venus, among many accomplishments. Rittenhouse also conducted important survey work for the state of Pennsylvania, establishing the state's western border, as well as overseeing the completion of the Mason-Dixon survey. In addition to his scientific endeavors, Rittenhouse's work for American independence places him among the important founding fathers. Subordinating his scientific interests for the greater good of Pennsylvania during the American Revolution, Rittenhouse served as a member of both the Pennsylvania Assembly and the Pennsylvania Constitutional Convention, and held powerful positions on the Pennsylvania Council of Safety and the subsequent Committee on Safety. Rittenhouse also served as the first director of the United States' Mint, at the behest of President George Washington. Rittenhouse was elected to the American Philosophical Society in 1768 and played a major role in placing the Society on the scientific map. He held many positions in the Society, including serving as its President from 1791 until his death in 1796. The Rittenhouse papers span 1774 to 1932, and consist of 61 items, over 0.25 linear feet. The collection is comprised mainly of correspondence, but also includes receipts, genealogies and broadsides.

From the Sugar Act of 1764 through the Tea Act of 1773, the British Parliament imposed a variety of taxes upon their American colonies in an effort to raise revenue to offset the enormous debts incurred during the Seven Years' (French and Indian) War. Far more efficiently than raising revenue, these duties raised the indignation of the colonits, contributing more than their share to the alienation that fueled the independence movement The two volumes that comprise the Pennsylvania Stamp Act and Non-Importation Resolutions Collection contain 34 manuscript and printed items relating to the political crisis over taxation on goods imported into the American colonies between 1765 and 1773, with a focus on Philadelphia. The first volume is concerned exclusively with agitation over the Stamp Act of 1765 and its repeal, while the second volume relates more specifically to the Non-Importation agreements of the 1760s, the Townshend Duties, and the Tea Act of 1773. Among these are letters of Governor John Penn, correspondence between the Sons of Liberty at Philadelphia and those of New York, 1766, an address of the committee of Boston merchants to a committee of Philadelphia merchants, 11 August 1768. Among the more dramatic letters are those from John Hughes, the would-be Stamp Officer for Pennsylvania who resigned bis commission in the face of public protest, and a seies of threatening letters addressed to James and Drinker, consignees for the sale of tea in Pennsylvania in 1773.

An early settler and prominent citizen in the Moravian heartland near Bethlehem, Pennsylvania, Timothy Horsfield was named justice of the peace when Northampton County was formed out of Bucks in 1752, and was one of those given responsibility for the defence of the local white and Christian Indian populations during the French and Indian War. The Horsfield Papers offer a window onto the tumultuous history of northeastern Pennsylvania during the 1750s and 1760s. Comprised largely of correspondence and related documents between Horsfield, William Parsons, and provincial and military authorities, the collection includes important information on the Native tribes' actions (previously described as "Indian assaults") in the region in 1756 and 1757 and the military and diplomatic response of settlers.
