Abstract:: Dr. Constantine Hering (1800-1880), born and educated in Germany, immigrated to Philadelphia in 1833 and devoted his life to the study, practice and education of homeopathic medicine in the United States. As such, he is considered the father of homeopathy in America. Hering founded several schools and organizations devoted to teaching homeopathy, especially the North American Academy of the Homeopathic Healing Arts, aka the Allentown Academy, in 1836, and the Hahnemann Medical College of Philadelphia in 1848. Hering’s pupil and eventual son-in-law and professional assistant, Dr. Calvin B. Knerr, also practiced homeopathy. Knerr was integrally involved in the editing of two of Hering’s books and also devoted much time and effort to writing Hering’s biography, The Life of Hering. This collection primarily houses papers of Dr. Constantine Hering and his son-in-law, Dr. Calvin B. Knerr from 1820 to 1940. To a significantly lesser extent, the collection documents the...(see more)

Abstract:: Zaccheus Collins (1764-1831) was a plant collector and herbarium owner from Philadelphia. Collins was an esteemed botanist and was often consulted by a majority of botanical writers, though he never published anything himself. He was also an avid collector and his herbarium contained a nearly complete collection of the plants from the vicinity of Pennsylvania and New Jersey. His correspondents also sent him various specimens from their research in the southern states, particularly South Carolina and Georgia. The collection contains letters that are entirely botanical in nature, coming from 55 individuals, and presents a cross section of the botanists and their problems in the early 19th century. There is significant correspondence from Henry Muhlenberg (1753-1815), Frederick Augustus Hall Muhlenberg, Stephen Elliott (1771-1830) and Dr. Jacob Bigelow (1787-1879), as well as many other important botanists of the era.

Abstract:: John Percy Moore (1869-1965) was a Professor of Zoology at the University of Pennsylvania from 1912 to 1939, an Assistant Curator at the Academy of Natural Sciences from 1902 to 1938, and held several positions between 1920 and 1956 at the Ludwick Institute, which offered free lectures and courses in the natural sciences. He was also a world recognized authority on leeches. During his career, Moore named six genera, 229 species, five subspecies and four varieties of polychaetous annelids, or segmented worms (Loi 1980). The J. Percy Moore papers document Moore's professional career as a zoologist, primarily his study of leeches and other annelids; educator; and biographer. The collection dates from 1847 to 1963 and consists of his specimen notes, sketches, photographs, 16 mm film, travel logs, and field notes related to his study of leeches and other annelids. The collection also contains materials related to his involvement with The Academy of Natural Sciences (ANSP) Board of...(see more)

Abstract:: The German Society of Pennsylvania, founded in Philadelphia in 1764, directed its early efforts to assisting new German immigrants, especially those forced into indentured servitude when they were unable to pay their sea fare. Throughout the late 18th and 19th centuries, the Society was very visible in the thriving German-American community in Philadelphia, boasting just over one thousand members at the peak of its growth, in the late 1870s. In the 20th century, the Society’s scope and prominence was affected by the two World Wars, which created suspicion and criticism of Germanic culture. That suspicion and government scrutiny played a role in the dwindling membership of the Society. In the post-World War II era the Society channeled its overseas relief activities through a Quaker-based aid society. In the second half of the century, the neighborhood was also changing, as it became predominantly African-American, rather than German, and more impoverished. But the Society pressed...(see more)

Abstract:: The Logan family was a prominent Philadelphia family dating back to 1699, when James Logan, the family patriarch, arrived in Philadelphia to serve as the first secretary of the Pennsylvania colony. Through work in agriculture and politics, Logan and his descendants were intimately involved in the development of the Pennsylvania colony and, later, the fledging United States. James Logan's prominence resulted in connections, both professional and familial, with other prominent colonial families, including the Norris and Dickinson families. The Logan family papers, 1638-1964 (bulk 1670-1872), documents James Logan’s personal and professional life, as well as that of several generations of his descendents. There are papers documenting the lives of his son William, his grandson George Logan, his great-grandsons Albanus Charles Logan and Algernon Sydney Logan, and the subsequent relationships with the Dickinson and Norris families. John Dickinson, who married one of James Logan's...(see more)
