These are the professional, personal, and family papers of Marsh, and include correspondence and unpublished writings.

The Linguistic Society of America was organized in 1924 in New York City, but there is little, if any, material in the archive relating to its early history. The bulk of the collection dates after 1960, although there is scattered correspondence and material for the decades prior to that time. There are administrative records (records of the officers, secretariat, committees, general correspondence); records concerning the summer linguistics institutes run by the LSA; annual meeting records; membership records; material relating to the publications of the LSA; and substantial material concerning affiliations with other organizations (ACLS, NAS, NRC, NEH, Social Science Research Council). There are also financial records of the Society.

Apart from its importance for the study of Hale's personal and professional life, the collection is one of the richest sources for the history of science in the United States in the early twentieth century. It contains a good deal of significant material relating to the theoretical and instrumental development of astrophysics and the history of the Mount Wilson and Palomar Observatories. The collection is of singular importance for the study of science and government, particularly with respect to the affairs of the National Academy of Sciences and the National Research Council. It documents much of the early history of the California Institute of Technology. Finally, it contains substantial material on the general affairs of the scientific community in the United States and Europe [from Kevles 1968].

The physicist, Emanuel Ruben Piore, emigrated from Vilnius, Lithuania, in 1917 at the age of 9. "Mannie," as he was known, became a naturalized citizen in 1924, and obtained both his BA and Ph.D. in physics from the University of Wisconsin. After gaining nearly ten years experience as a research physicist, first at the Radio Corporation of American then CBS laboratories, he went to work for the Navy, eventually becoming the first civilian to head the Office of Naval Research and playing a major role in the transition of American science from war to peace. Throughout his career, Piore strove to promote research through a close relationship between government, industry, and universities. IBM realized the importance of developing a strong research department and Piore's key role in this endeavor and offered him the position as their first Director of Research. At IBM he continued to encourage research by establishing the IBM Fellow program rewarded to top researchers. Piore held increasingly responsible positions at IBM becoming a vice president, group executive and finally Chief Scientist. He served as a member of IBM's advisory board well after he retired. The Piore papers contain material relating to his latter years at IBM as Vice President and Chief Scientist, as well as some of his time spent on the Board of Directors. In addition, there are materials, though sparse, concerning his work with the Navy. An extensive series of speeches and lectures illustrates Piore's commitment to scientific research and national policy. In addition to his professional correspondence, the papers contain material pertaining to Piore's involvement in professional organizations such as the National Academy of Engineering, National Academy of Science, Sloan-Kettering Institute for Cancer Research and the American Philosophical Society. A number of professional and personal photographs are also found within the papers.

These are chiefly working papers on subjects requiring statistical analysis and letters, reports, and papers relating to professional organizations. There is little personal material.

These documents cover the years 1847 to 1953, the year of Millikan's death, but the core of the collection consists of the official papers generated by Millikan after his move to Pasadena in 1921. The collection includes more than 125,000 pages of letters, notebooks, unpublished speeches, addresses, lecture notes, and family papers.

The papers of anthropologist Ward Goodenough cover his whole career, most of it spent in the Department of Anthropology at the University of Pennsylvania. After service in army during WW II, Goodenough received a Ph.D. from Yale in 1949. He conducted field research from 1947 to 1965, working at Chuuk (Truk), the Gilberts, Papua New Guinea, and New Britain. The collection is particularly important in showing how linguistic theory can help further anthropological theory.

This collection includes correspondence, research data, reviews of grant proposals, organizations participated in, laboratories worked for, and student recommendations. The correspondence in the collection dates primarily to the 1960s-70s, when Mildred Cohn worked at the University of Pennsylvania and at the Institute for Cancer Research in Philadelphia, later renamed, Fox Chase Cancer Center. The letters are professional in content, discussing biochemistry, molecular biology, nuclear magnetic resonance (NMR) experiments. The letters also concern lectures and participation in conferences and symposia, and there are materials relating to recommendations for students and colleagues for positions and promotions. Dr. Cohn's interest and involvement in the issue of women in science is presented, of particular note, her work with the University of Pennsylvania's Gender Equity Committee. The notebooks, by Cohn, her colleagues and students, contain extensive experimental data.

Correspondence and reports relating principally to medical research (tuberculosis, cancer, lymphatic system, pernicious anemia), writings and publications. There is material of note on the following organizations: American Association of Anatomists, American Association of University Women, American Woman's Association, Henry Strong Denison Medical Foundation, John Simon Guggenheim Memorial Foundation (re. fellowships), Hall of Fame for Great Americans, Institute for Advanced Study, Johns Hopkins School of Medicine, Medical Aid to China, Medical Aid to Spain, Naples Table Association (this existed to promote laboratory research by women); National Academy of Sciences, National Tuberculosis Association, Peking Union Medical College, Rockefeller Institute, Ellen Richards Prize (awarded by the Association to Aid Scientific Research by Women), Society for Experimental Biology and Medicine, University in Exile (i.e. New School for Social Research), White House Conference on Child Health and Protection, and the World Center for Women's Archives. There are abstracts and notes of unpublished scientific papers, and also materials for her biography of Franklin Paine Mall, 1934.

Britton Chance (1913-2010) was a biochemist and biophysicist as well as a pioneer in the field of biomedical optics. Chance received his Ph.D. in Physical Chemistry from the University of Pennsylvania in 1940 and his Ph.D. in Biology and Physiology from Cambridge University in 1942. Over the course of his nearly eight decade career, Chance was dedicated to the application and transfer of basic scientific research and technology to clinical medicine. The Britton Chance Papers contain correspondence, research notes, experimental data, publication materials, and photographs stemming from Chance's life as a biochemist, biophysicist, and yachtsman. The collection is broken up into fifteen series that document every aspect of his scientific work.

Alexander Hollaender was a leading researcher on the genetic effects of radiation. Born in Samter, Germany, in 1898 and arriving in the United States in 1921, Hollaender was educated at the University of Wisconsin, receiving his AB, MA, and Ph.D. there. He served on the faculty at the University of Tennessee and the University of Tennessee-Oak Ridge Graduate School of Biomedical Sciences. He was director of the division of biology at the Atomic Energy Commission's Oak Ridge National laboratory from 1946 until 1966. The 4 linear feet of the Alexander Hollaender Papers contain incoming and outgoing correspondence and reports relating to the genetic effects of radiation, specifically atomic radiation. Also included are documents of the International Conference on the Peaceful Uses of Atomic Energy; the NAS Committee on the Biological Effects of Atomic Energy, Genetics Panel; the United Nations Scientific Committee on Atomic Radiation; and the World Health Organization all of which Hollaender was closely involved with.

Raymond Pearl spent the majority of his academic career (1918-1940) at Johns Hopkins University, where he was Professor of Biometry and Vital Statistics and Director of the Institute of Biological Research. Founder of the Quarterly Review of Biology and Human Biology, he made significant contributions in the areas of biology, genetics, eugenics, and statistics. The Pearl Papers includes correspondence as well as notebooks, scrapbooks, diplomas, photographs, and 33 volumes of diaries. There is significant correspondence with his wife, Maud (ca. 500 letters), and mother, Ida May (ca. 300 letters), particularly for the years 1895-1934. Of special note is Pearl's correspondence with his friend, colleague, and fellow Baltimoreian, H. L. Mencken (ca. 500 letters). The collection contains important information on the American Association of Physical Anthropologists, The Baltimore Sun, the Birth Control Federation of America, Dartmouth College, the International Institute of Statistics, Johns Hopkins University, and the National Academy of Sciences. This note is currently under review for revision.

William Jacob Robbins (1890-1978, APS 1941) was a botanist and physiologist. From 1937 to 1957 he was director of the New York Botanical Garden. His research focused on culture methods of plants in relation to biochemistry and nutrition, especially on the synthetic abilities of fungi. His studies paralleled the scientific agenda of the Rockefeller Foundation, an agency with which he was closely associated for years as adviser and trustee. He was perhaps the most influential botanist in the National Academy of Sciences (NAS) during the early postwar era, and a principal participant in the plans for the global reconstruction of science. Robbins served as president of the American Philosophical Society from 1956 to 1959.

One of the most influential statisticians of the twentieth century, John Wilder Tukey (1915-2000) played a key role in both the development and study of statistics. Upon receiving his Ph.D. in mathematics in 1939 from Brown University, he joined the faculty at Princeton; in 1945, he also began work at Bell Laboratories. Equally committed to both Princeton and Bell Labs, Tukey chose to work concurrently at both institutions. He was also a consultant for many companies, such as Merck and Company, Xerox Corporation, and the Educational Testing Service, and was a frequent advisor to the government for such programs as the US Census. From 1960 to 1980 he led the statistical component of NBC's election night projections. Among other projects Tukey analyzed Alfred Kinsey's research and examined data on ozone depletion. Tukey made many important contributions to the field of statistics, such as work in time series analysis, exploratory data analysis, and multiple comparisons. Through his work, Tukey developed statistical applications including the Box-and-Whisker Plot, the Stem-and-Leaf Diagram, Cooley-Tukey Fast Fourier Transforms, Tukey's Paired Comparisons and citation and permutated indices. Tukey's influence extends beyond statistics to everyday language: he was the first to use the word "software" in print and coined words such as "bit" and "linear programming." A prolific writer, John W. Tukey penned more than 500 technical papers and reports and published, among numerous other works. His collected papers amount to eight volumes of work. The Tukey Papers provides a comprehensive perspective into Tukey's professional activities from his days as a graduate student until his death in 2000. Among the material is his correspondence and his published and unpublished works. There is abundant material from Tukey's long careers at Bell Laboratories and Princeton University, including extensive lecture notes and syllabi. Also included are copious materials relating to his professional activities with such agencies as the National Research Council, the Army Records Office, Xerox PARC, Merck and Company, the President's Science Advisory Committee, and the National Academy of Sciences.

Leonard Carmichael was a psychologist whose most significant contributions were made in the fields of child psychology and biopsychology. Educated at Tufts and Harvard, he taught at Princeton, Brown, and Rochester, later returning to Tufts to serve as its President from 1938-1952. An outstanding administrator, Carmichael served as executive officer for the Smithsonian Institute from 1952-1964, and was subsequently vice president for research and exploration at the National Geographic Society. In his later years, he served as President of the American Philosophical Society from 1970-1973. This large and varied collection reflects the entire range of Carmichael's prolific career. It includes a variety of types of records, including correspondence, committee reports and records, long series of articles and speeches, drafts of papers and books, and pocket notebooks. All phases of his professional life are covered, from his years in academia, to his time at the Smithsonian Institute and the National Geographic Society, as well as his involvement in a large number of professional organizations.

A biochemist at Columbia University, Erwin Chargaff discovered the base-pairing regularities or "complementarity relationships" of nucleic acids that provided one of the key steps in developing a structural model for DNA. During his long career, Chargaff is credited with conclusively falsifying the tetranucleotide hypothesis; demonstrating the existence of a large number of DNA species; and creating the first descriptions of hypochromicity, hyperchromicity, and the denaturation of a DNA. In addition, Chargaff conducted important research on blood coagulation, lipids and lipoproteins, the metabolism of amino acids and inositol, and the biosynthesis of phosphotransferases. He retired to emeritus status in 1974 and remained active in research almost to the time of his death in June 2002. The Chargaff Papers are organized into ten series: I. Correspondence, 1931-1992; Ia. Correspondence, 1949-2002; IIa. Grants, 1930-1982; IIb. Subject Files, 1940-1984; IIc. Subject Files, 1946-2002; III. Works by Chargaff, 1929-1989; IIIa. Works by Chargaff, 1923-2002; IIIb. Reprints, 1977-1999; IV. Works by Others, 1936-1985; IVa. Works by Others, 1976-2002; V. Research Notes and Notebooks, 1929-1951 ; VI. Photographs, 1935-1977; VIa. Photographs, 1928-2002; VII. Audiovisual Materials; VIII. Awards and Certificates, 1958-2001; IX. Lecture Notes, 1942-1985; X. Personal Papers, [1880]-1985.

After receiving his doctorate from Harvard in 1923, the physicist John Clarke Slater did postgraduate work at Cambridge University and on the continent working n quantum theory with both Niels Bohr and Werner Heisenberg. Slater was appointed to the head of the department of physics at MIT in 1930, which he and Karl Compton worked effectively to transform into one of international stature. His own work on the electromagnetic theory of microwaves was fundamental to the development of radar systems. During the Second World War, he was affiliated with the radiation laboratory and after he helped found the solid state and molecular theory group, the interdisciplinary Center for Materials Science and Engineering, the Research Laboratory of Electronics, and the Laboratory for Nuclear Science. After his retirement from MIT in 1966, Slater moved to the University of Florida, remaining active until his death in 1976. The Slater Papers contains a wealth of information on the development of physics at MIT, as well as Slater's post-1966 work at the University of Florida. There are about 133 (7 linear ft.) research notebooks, 1944-1976, and a long series (30 linear ft.) of folders, containing lectures, scientific notes, drafts of manuscripts and papers, correspondence during his collaboration with the Los Alamos Labs, 1966-1970, and extensive correspondence relating to the National Academy of Science. Information about American-Swedish exchange in quantum science is located in the correspondence with Per-Olov Löwdin.

Sewall Wright ranks among the most influential figures in the field of population genetics during the 20th century, and made important contributions to biostatistics, biometrics, and evolutionary theory. These papers contain much of Wright's professional correspondence, scattered research notes, and drafts of a small number of papers.

One of the seminal figures in the emergence of the Modern or Neo-Darwinian Synthesis during the mid-twentieth century, George Gaylord Simpson (1902-1984) helped define the unique contribution made by vertebrate paleontology to the life sciences. A specialist in Mesozoic and early Cenozoic mammals, Simpson's contributions to the fusion of Darwinian natural selection and Mendelian genetics were both empirical and theoretical, culminating in his major works Tempo and Mode in Evolution and The Meaning of Evolution. From his posts at the American Museum of Natural History (1927-1959), Columbia University (1945-1959), Harvard (1959-1967), and the University of Arizona (1967-1984), Simpson became one of the most influential paleontologists of the century, helped in part by his ability to write successfully for both a technical, professional audience and a popular audience. The Simpson Papers include a comprehensive assemblage of professional and personal correspondence, reflecting nealy all phases of Simpson's career. Written with charm, wit, and a sense of literary style, the correspondence touches on all aspects of modern paleontology, providing an important perspective on the emergence of contemporary evolutionary theory, biogeography, systematic theory and methodology, the relationship of science and religion, and creationism, as well as more general issues in scientific epistemology and social and political issues. The collection also includes autobiographical data and writings, lectures, class notes and papers, research data, material on his scientific expeditions (diaries in carbon form, photos, notes, etc.), publication material (he was author of some 800 publications), extensive photographic material, diplomas, and medals.
