This collection contains essays edited by Cheyney and published in "Annals" of the American Academy of Political and Social Science 200(1938). Included are 13 letters, 1936-1938, about the manuscript to and from Edwin G. Conklin, Walter B. Cannon, and Roy F. Nichols. Concerning freedom of expression in various fields: inventions, social sciences, science, religion, working men, universities in various countries.

A key spokesman for the medical establishment against the antivivisection movement, Walter B. Cannon was head of the Council for the Defence of Medical Research of the American Medical Association from 1908 to 1936. He and his colleague William W. Keen monitored antivivisectionist activity, mobilized the medical profession, lobbied politicians, testified in public hearings, and wrote tirelessly in defense of animal experimentation. Cannon was George Higginson Professor of Physiology at Harvard Medical School and head of its physiology department. Keen was a prominent surgeon and neurologist from Philadelphia. The Cannon Papers consist of over 1.5 linear feet of correspondence, 1905-1928, primarily between Cannon (1871-1945) and Keen (1837-1932) regarding their mutual opposition to the antivivisection movement.

These letters to Severinghaus concern diabetes, endocrinology, nutrition, and information about grants and funds. Correspondents are mostly represented by one letter.

The bacteriologist and virologist Thomas Milton Rivers spent over thirty years at the Rockefeller Institute as a researcher in the Department of Bacteriology and from 1937-1955, as Director. Working on measles and pneumonia, Rivers discovered the parainfluenzae bacillus and cultivated vaccine virus for human use, and during the 1950s, he played an important role in coordinating research on poliomyelitis as head of the National Institute for Infantile Paralysis. During the Second World War, Rivers led the Naval Medical Research Unit in the South Pacific, rising to the rank of Rear Admiral. The Rivers Papers contains correspondence, laboratory notes, speeches, and photographs documenting Rivers' activities at the Rockefeller Institute, the development of polio vaccine, and Rivers' Navy experience in the Pacific during World War II.

In addition to extensive correspondence, there are numerous laboratory notes, lecture notes, drafts of published papers, reports. This material documents Long's career, with much on his work with diabetes, including the International Diabetes Federation. His 1950 trip to Japan as an advisor to Japanese medical schools on medical education is also documented. In addition, there is substantial material on the Yale University Department of Physiology and the School of Medicine.

This collection of correspondence and documents focuses on Roughton's prolific life's work on respiratory physiology. His specific work at Cambridge University from the 1920s to the 1960s, as well as interludes in the U. S. during World War II, are covered, as is the scientific milieu in which he worked. Some of the subjects or organizations for which there are documents, are: Bermuda and Naples Zoological Research Stations; British Glue and Gelatin Research Assoc.; Biochemical Journal; Cambridge Philosophical Society; Cambridge University Departments of Physiology (pre-1939) and Colloid Science (post-1940); Harvard Fatique Lab.; Medical research Council; Trinity College Cambridge.

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.

An administrator and humanist, Henry Allen Moe (1894-1975) was the first director of the National Endowment for the Humanities, and was a president of the American Philosophical Society from 1959 to 1970. The Moe Papers are a vast and rich resource documenting all phases of Moe's career, but are also a major source of information on twentieth-century philanthropic organizations. As the first Secretary, then Administrator, and finally President of the John Simon Guggenheim Foundation (ca. 1925-1963), Moe made contact with the influential and the aspiring in the worlds of banking, finance, the arts, and sciences. This collection is particularly strong in correspondence and information relating to Latin America, much of it generated through Moe's oversight of the Guggenheim's Latin America Fund and by Moe's otherwise keen interest in the region. This material is diverse, ranging from material on agriculture (see Escuela Agricola Panamericana, 15 boxes) and Peruvian archaeology (see Alfred Kroeber's detailed report) to many folders of correspondence and grant reports from artists, writers, and politicians of South and Central America. Moe served as trustee, officer, and committee member of over thirty private foundations, many of which are well represented in the collection by yearly reports and grant applications, among other types of records.
