Correspondence, subject files, lectures and addresses, awards, citations and certificates, telephone notes, office calendars and personal appointment books, audio and video tape recordings, photographs, slides, and other material documenting the career of William Nierenberg. The collection contains material dated 1932-1986, but consists largely of personal papers covering the years 1965-1985, when Nierenberg was Director of the Scripps Institution of Oceanography. There is also material documenting Nierenberg's work at the University of California, Berkeley, including correspondence, lecture notes, and committee service. Records related to his leadership role in the Atomic Beams Research Group are very limited. The collection includes almost nothing regarding either Nierenberg's tenure at the University of Michigan or his contributions to the Manhattan Project. The papers proved extensive documentation of his participation in professional and scientific associations, his consulting activites and wide-ranging government service, and his participation in international scientific forums. There is some information regarding the JASON but little about Nierenberg's individual contribution to this group. His activities as a member of the National Research Council's Climate Research Board, the National Advisory Committee on Oceans and Atmosphere, the National Aeronautics and Space Administration Advisory Committee, the National Science Foundation Committee on International Science, and the White House Office of Science and Technology Policy Acid Rain Review Panel are amply covered. The collection includes files regarding Nierenberg's long association with the North Atlantic Treaty Organization. His role as NATO Science Advisor, particularly his part in the development of the International Institute of Science and Technology is well documented. Also covered are organizations such as Tel Aviv University, the Center for Naval Analyses, and the La Jolla Institute, among others. The collection includes correspondence and committee records related to Nierenberg's role as a University of California, San Diego vice chancellor and member of the Physics Department. There are also files covering his work on the Scripps Institution of Oceanography Capricorn Expedition (1952) and his participation in expeditions to the Arctic (1949), Bikini Atol (Crossroad, 1946), local civic groups, his social engagements, and his personal travel. Among his correspondents: Sir Edward Crisp Bullard, Cecil H. Green, Andrei Monin, Frank Press, Roger Randall Dougan, Revelle, Henry Stommel, and Harald Ulrik Sverdrup.
