The plant physiologist and historian Rodney H. True (1866-1940) divided his career relatively evenly between the Bureau of Plant Industry in United States Department of Agriculture and the Department of Botany and Morris Arboretum of the University of Pennsylvania. A specialist in the physiological function of mineral nutrients in plants, True was active in his later career in the Philadelphia Society for Promoting Agriculture, the Pennsylvania Horticulture Society, and the Agricultural History Society. The True Papers consist of 6 linear feet of material relating primarily to the period of his career spent at the University of Pennsylvania. The collection contains roughly equal proportions of personal and professional correspondence, with a few diaries and research notebooks documenting his involvement with professional organizations and his interests in the history of his discipline.

Harriet Verena Evans was born in Lancaster, Pa., on April 28, 1782, the daughter of John and Sarah Musser. On May 21, 1807, Harriet married Cadwalader Evans (1762-1841), a former surveyor who went on to a distinguished career in politics, as one of the directors of the Bank of the United States, a promoter of the Schuylkill Canal, and president of the Schuylkill Navigation Company. The couple had nine children, including a set of twins. The diary of Harriet Verena Evans is an unusual example of a woman's spiritual diary from early national Philadelphia. Beginning on her 46th birthday in 1827, the same day her seventeen year-old son John died, Evans made sporadic entries in her diary for seventeen years, marking birthdays, holidays, special events, and anniversaries of various kinds. Fixated upon praying (or fretting) over her spiritual state and future, Evans continued to mourn over John's loss for many years, remembering him regularly on the date of his birth, death, and burial. She was also particularly prone to composing (or copying) religious poetry, and in sections, the diary verges on a poetical commonplace book. Other entries reveal Evans' concern for her other children, three of whom were students at the University of Pennsylvania, and on July 25, 1832, she made a particularly long entry discussing the arrival of the cholera in Philadelphia.

Jacob Hiltzheimer, farmer and assemblyman, emigrated from Germany to Philadelphia in 1748 and lead a moderately active political and social life. He was a successful farmer and raised select livestock in the city of Philadelphia. He also boarded horses including those of John Penn and George Washington. He served in the Pennsylvania Assembly for 11 consecutive years beginning in 1786. He was an active contributor in civil affairs and took a remarkable enthusiastic interest in events, in persons, and in every day life all of which he wrote down in his diary. As a result of his Revolutionary War and political acquaintances his contacts were numerous. Hiltzheimer's record of social affairs are for the most part routine daily events such as buying and trading horses, attending barbecues and funerals, and drinking punch. However it is his every day accounts that also records significant events such as the Revolutionary War, transactions of the Pennsylvania Assembly, and Philadelphia's yellow fever epidemics, as well as the dealings of significant people including George Washington, Thomas Mifflin, and John Hancock.

A physician, natural historian, and professor at the University of Pennsylvania, Benjamin Smith Barton (1766-1815) was one of the central figures in Philadelphia's early national scientific establishment. Having received his medical training in European universities, Barton was appointed Professor at the University of Pennsylvania in 1789, lecturing on botany, materia medica, natural history. A prolific author, he established his reputation as one of the nation's preeminent botanists through his botanical text book The Elements of Botany (1803), but his contribtions to zoology, ethnology, and medicine were equally noteworthy. Barton's monograph on the "fascinating faculty" of the rattlesnake and his efforts in historical linguistics (New Views of the Origin of the Tribes and Nations of America, 1798) were widely read, and his Philadelphia Medical and Physical Journal (1804-1809) was one of the nation's first medical journals and an important outlet for natural historical research. The Barton Papers offer a comprehensive view of the professional work of Benjamin Smith Barton from the time of his return to the United States in 1789 until his death. The collection is divided into five series: Correspondence, Subject Files, Bound Volumes, Graphic Materials, and Printing Plates. The collection includes a particularly valuable series of botanical, medical, and natural historical drawings collected by Barton for research, reference, and publication. Among the many artists represented are William Bartram, Frederick Pursh, Pierre Turpin, and Benjamin Henry Latrobe.

One of the oldest houses in Philadelphia, Wyck is now a non-profit museum listed on the National Register of Historic Places. Nine generations of the Jansen-Wistar-Haines family owned the Wyck property from 1690 until 1973. The last family owner deeded 2.5 acres of land, the house and its contents, several outbuildings, a landscaped garden, and a small endowment to the Wyck Charitable Trust. The Wyck Charitable Trust and the Wyck Association now administer the preservation of the property and its educational services to the public. This collection contains diaries, letters, accounts, bills and receipts, deeds, and photographs. The collection as a whole is deepest for the period 1770-1970. Items of particular note include accounts of household expenses at Wyck from ca. 1790-1970; papers pertaining to the Academy of Natural Sciences of Philadelphia, Quaker schools, and social reform groups; agricultural and horticultural practices; and correspondence to and from cultural leaders of 18th and 19th century Philadelphia. The papers of the John S. Haines family (Ms. Coll. 52A) form part of the Wyck Papers. The papers cover the years 1845 to 1949 and are arranged into eight series.

Henry Muhlenberg's notebooks (1784-1813), written in Latin or German script, in a small hand, includes a wealth of botanical observations, with a focus on Lancaster, Pennsylvania. The Henry Muhlenberg journals are a record of daily occurrences, with many features of a commonplace book, containing prescriptions, notes of questions asked candidates for the Lutheran ministry, and the plan of a barn. There is also a biographical account of Rev. Henry Melchior Muhlenberg (1711-1787).

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.

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.

A merchant and member of the Society of Friends, Pim Nevins (1756-1833) lived most of his life in the English midlands. Recorded in Pigot's Directory of 1834 as a member of the gentry resident in Hunslet Lane, Leeds, Nevins was a woollen cloth manufacturer, finisher, and merchant whose operations were located at Larchfield Mill, near Huddersfield. During a voyage to visit Friends' meetings in the United States in 1802-1803, Pim Nevins kept a journal to record his thoughts and experiences. In presenting a copy of his diary to his children, he wrote: "some parts [of the diary] wch. being by way of memorandum to assist my memory will of course be no ways interesting to you; other parts being fill'd with the effusions of my own thoughts, will I fear be dry to you unless your minds should in some measure be dip'd into the like state with mine when influencing my pen; some other parts may entertain you." The journal includes a mixture of description of the cities, towns and landscape through which Nevins passed and accounts of his visits with Friends in New York city, Philadelphia, Wilmington, Baltimore, Washington, Alexandria, Bethlehem, Pa., Easton, Pa., the Pocono Mountains, northern New Jersey, New Brunswick, N.J., and Trenton, N.J. It also includes a delicate watercolor drawing of the Delaware Water Gap.

Twice a refugee from the revolutionary violence in the French colony of Saint Domingue, John Thomas Carré became head of the Clermont Seminary in Philadelphia from 1804-1825, a select boarding school for boys. Carré's diary from 1807-1809 provides a basic chronology of his life at the Clermont Seminary, with a few comments on his students and their families. The entries are typically very brief and are confined to a relatively limited range of topics, including the weather, Carré's poor health, his visitors, and correspondents. There is also a biographical memoir by his granddaughter, Ann Virginia Sanderson Farquhar.

Norman Leonard Jacobs was an engineer and surveyor with the Grand Trunk Pacific Railway in Canada. The collection consists of his correspondence with Bessie Frank (later Anathan), an acquaintance from Pittsburgh. Jacobs wrote of daily life in Canadian cities, interactions with First Nations tribes, and daily hardships encountered in the field (extreme cold, snowblindness, and lack of food), but also spoke of his work with pride and enthusiasm. In addition to the letters, Jacobs wrote twenty-eight pages of a "Diary of a Tenderfoot." Also included in the collection are two photobooks and various loose photographs, which display various aspects of camp life, details of work sites and landscape, as well as First Nations families, camps, and modes of transportation.

From the 1920s through the 1940s, the University of Pennsylvania anthropologist Frank Gouldsmith Speck worked on Cherokee language and culture with his primary consultant, Will West Long. Raised in Big Cove, North Carolina, Long was a respected elder and spent much of his adult life attempting to record and preserve traditional Cherokee culture. The Speck Cherokee Collection consists of diaries, accounts, and medicinal texts in Cherokee collected by Will West Long and Morgan Calhoun, accompanied by notes by Speck and John Witthoft. Among these are several diaries kept by Long (mostly 1904-1917), records of the Gadugi (a Cherokee mutual aid group), accounts, records of births and deaths at Big Cove, Cherokee-English vocabularies, and material collected on Cherokee botany collected by James Mooney in 1887. Several of the items contain information on Cherokee medicine, including formulae and curing charms.
