An anthropologist and student of Native American cultures, Elisabeth Tooker devoted a long career, much of it as a professor at Temple University, to study of the culture and ethnohistory of the Haudenosaunee of New York State. The Tooker Papers is arranged in six series, and contain her correspondence, subject files, research notes, and both published and unpublished papers.

Simon Flexner, born in 1863, one of the nation's leading experts in pathology and bacteriology, was most renowned for his research on cerebrospinal meningitis, polio and infantile paralysis. Arguably though, Flexner's stewardship of the Rockefeller Institute was his greatest contribution to medical and scientific research. His rise in the medical community began in the late nineteenth century in Louisville, Kentucky, where despite not having completed even the seventh grade, Flexner taught himself basic bacteriology by conducting experiments at home using a microscope borrowed from the pharmacy where he served as an apprentice. Granted a medical degree from the University of Louisville School of Medicine in 1889, he went on to a pathology fellowship at the newly opened John Hopkins School of Medicine. Within two short years of leaving Louisville, Flexner received an assistant of pathology appointment at Johns Hopkins. It was a quick ascent and the beginning of a long and brilliant career that included a prestigious appointment at the University of Pennsylvania and then a directorship at the new Rockefeller Institute where he realized his lifelong dream of creating a dynamic and productive research laboratory. The Rockefeller Institute became instantly famous worldwide as the preeminent research facility for virology and under Flexner's direction produced invaluable contributions in pathology, bacteriology, and immunology. This collection does not reflect the early phases of Flexner's career at Johns Hopkins but does document an early interest in meningitis and other infectious diseases with science-related correspondence, laboratory notebooks, and administrative correspondence with the New York City and State Departments of Health. There is abundant material on Flexner's directorship of the Rockefeller Institute for Medical Research, including Flexner's search for staff, an involved process which is detailed in correspondence with the scientists, many of whom became quite famous. Also included is material relating to the other institutions and Rockefeller philanthropies with which Flexner was involved. (Among the most significant correspondence, however, may be that which documents the support of the General Education Board and the Rockefeller Foundation in the development and subsequent reorganization of medical schools following brother Abraham Flexner's scathing report on medical education in the United States and Canada). This collection would be of great interest to anyone interested in the history of bacteriology, histology, and immunology or the general history of modern medicine and philanthropy.

Alfred Irving ("Pete") Hallowell was an anthropologist best known for his studies of Ojibwa culture and world-view, and the innovative use of the Rorschach Test in his studies of the psychological interrelations of individuals and their culture. Early in his career, Hallowell worked as a social case worker for Family Service, and even after moving on to study anthropology in 1920 (M.A.), he carried with him an interest in ethnic and racial culture, developing additional interests in psychological testing. Except for the years 1944-1947, when he taught at Northwestern University, Hallowell spent his entire career at the University of Pennsylvania where he was professor of anthropology, professor of anthropological psychiatry in the Medical School, and curator of social anthropology at the University Museum. A cultural anthropologist, Hallowell's use of clinical psychological methods, especially Rorschach tests, was both innovative and controversial in his discipline. In his research, he concentrated on the Algonkian Indians, especially the Abenaki and Ojibwa Indians of Canada and Wisconsin (Berens River, Lake Winnipeg, Manitoba, and Lac du Flambeau, Wisconsin areas), and the Saulteaux of Berens River. The Alfred Irving Hallowell Papers (1892-1981) contain correspondence, subject files, manuscripts of published and unpublished works by Hallowell, papers by colleagues and students, research notes kept by Hallowell, with a special emphasis on social organization, personality, behavior, psychology, religion, and folklore. The collection of several hundred photographs provides rich graphic documentation of Hallowell's work among the Ojibwa and Abnaki Indians during the 1930s.

Elsie Clews Parsons (1875-1941) was trained as a sociologist at Columbia University, but made her greatest achievements in the fields of anthropology and folklore. Parsons' early works in the field of sociology dealt primarily with gender roles, conventions of society, and the effect of society's pressures on the individual. After a trip to the American Southwest with her husband in 1910, Parsons' interests turned to anthropology. She began making field trips to Arizona and New Mexico and, under the influence of her friend Franz Boas, Parsons recorded in meticulous detail data on social organization, religious practices, and folklore of the Southwest Indians. Concurrently, Parsons conducted research in folklore, concentrating on folk tales of Afro-Americans and Caribbean peoples. She was active in a number of professional associations and was the associate editor of the Journal of American Folklore from 1918 until her death. The Parsons Papers were acquired as two separate accessions and remains organized in two distinct subcollections. Subcollection I (572 P35), acquired in 1949, contains approximately 12 linear feet of materials focused on Parsons' career in anthropology. Subcollection II, acquired in 1985, consists of 26.25 linear feet of materials divided into ten series, covering a larger scope of Parsons' life, including family and personal correspondence.
