Victor Frederick Weisskopf was born in Vienna, Austria, on September 19, 1908, to Emil and Martha Weisskopf. After attending the gymnasium, where he joined a socialist student group and worked with the Social Democratic Party (Kaiser 2007, pp. 45-46), Weisskopf began to study physics at the University of Vienna. In 1928, following a recommendation by Hans Thirring, one of his professors in Vienna, Weisskopf went to Göttingen to continue his studies with Max Born. He received his Ph.D. in 1931 based on his work on the application of quantum theory to the width of spectral lines.

During his early research career Weisskopf continued working on the basic problems of quantum physics, first with Werner Heisenberg in Leipzig, where he went in the fall of 1931, followed by a brief period spent as a temporary research associate of Ernest Schrödinger in Berlin. In the summer of 1932 Weisskopf went to Kharkov, Soviet Union, where he lectured at the Physico-Technical Institute. A year-long Rockefeller Foundation grant, received in the fall of 1932, allowed him to join Niels Bohr and his group in Copenhagen, and Paul Dirac in Cambridge, England. For two years, between 1934 and 1936, he held the position of research associate to Wolfgang Pauli at the Institute of Technology in Zurich. His last appointment in Europe was again with Niels Bohr in Copenhagen, where he worked from April 1936 to September 1937.

In the fall of 1937, to escape the growing Nazi threat, Weisskopf immigrated to Rochester, New York, where he was an instructor and then an assistant professor at the University of Rochester. From 1943 to 1946 Weisskopf served as deputy chair (with Hans Bethe as chair) of the theoretical division of the Manhattan Project in Los Alamos.

His decades-long association with the Massachusetts Institute of Technology began in 1945 when, recruited by Jerrold Zacharias, Weisskopf joined the faculty of the physics department, where he resumed his scientific research and assumed teaching duties as a professor of physics. In 1965 he was named Institute Professor, a position he held until his retirement in 1974. During that period, from 1967 through 1973, he served as the head of the Department of Physics and played a crucial role in the formation of the Center for Theoretical Physics. From 1974 until the end of his life Weisskopf held the titles of Institute Professor Emeritus and Professor of Physics Emeritus.

In addition to his scientific work, teaching, and administrative duties at MIT, Weisskopf played a major role in setting directions of research in high energy particle physics both in the US and in Europe. In 1960 he was invited to serve as the director general of CERN (the European Organization for Nuclear Research), a position he assumed in 1961 and held through 1965. Upon his return to the US, he became heavily involved in the efforts leading to the creation of the High Energy Physics Advisory Panel of the Atomic Energy Commission and served as its chair from 1967 through 1973.

Throughout his life Weisskopf was involved in the activities of many professional societies, both in the US and abroad. He was a member of the American Academy of Arts and Sciences and served as its president from 1976 to 1979. As a fellow of the American Physical Society he held the position of vice president in 1959 and president in 1960. He was a member of the Pontifical Academy of Sciences, the National Academy of Sciences, the Academy of Arts and Sciences, and various international organizations including French, Austrian, Danish, Bavarian, Scottish, Spanish, and Russian academies.

Weisskopf received numerous awards for both his scientific and social contributions, including the Max Planck Medal of the German Physical Society in 1956, the George Gamow Medal in 1968, the Boris Pregel Prize from the New York Academy of Sciences in 1971, the Prix Mondial Cino del Duca for Humanism in 1972, the Ludwig Boltzmann Prize for 1976, the Ludwik Smoluchowski Medal in 1977, the Orden Pour le Merite in 1978, the US National Medal of Science in 1980, the Wolf Prize in Physics for 1981, the Ehrenzeichen der Republic Österreich für Kunst und Wissenschaft in 1982, the J. Robert Oppenheimer Medal in 1983, the Sigma Xi Proctor Award in 1984, the Enrico Fermi Award from the US Department of Energy in 1988, the Public Welfare Medal from the National Academy of Arts and Sciences in 1991, the Compton Medal for Statesmanship in Science from the American Institute of Physics in 1992, and the Gian-Carlo Wick Medal from the World Federation of Scientists in 1994. He also received numerous honorary degrees.

During his long career as a theoretical physicist Weisskopf made significant contributions to the fields of quantum electrodynamics, nuclear physics, and the physics of elementary particles. (For an overview of his scientific contributions, see Kaiser 2007, pp. 44-56; Jackson and Gottfried 2003, pp. 3-27; and Stefan 1998.) He was an inspired teacher and an avid advocate of nuclear disarmament, an open exchange of information among scientists of all nations, and the freedom of individuals to express their beliefs. Over his career, Weisskopf published over two hundred papers on a variety of topics including quantum theory, nuclear and particle physics, science policy, and nuclear disarmament. He also authored and coauthored several books including Theoretical Nuclear Physics with John Blatt in 1952, Concepts of Particle Physics with Kurt Gottfried in 1984-1986, and an autobiography, The Joy of Insight: Passions of a Physicist, in 1991.

His first wife, Ellen (nee Tvede), whom he married in 1934, died in 1989. They were the parents of two children, Thomas Weisskopf and Karen Weisskopf Worth. In 1991 Weisskopf married Duscha Schmid. Weisskopf died on April 22, 2002, at the age of 93.

The collection documents the professional life and career of Victor Frederick Weisskopf (1908-2002) from the 1920s through 2002. Educated in Europe in the 1920s and 1930s, Weisskopf made important contributions to the quantum theory of radiative transitions, the self-energy of electrons, the electrodynamic properties of the vacuum, and the theory of nuclear reactions. In 1943, several years after his move to the United States, Weisskopf was invited to join the Manhattan Project, where he served as deputy chairman of the theoretical division.

He was a member of the faculty at the Massachusetts Institute of Technology in the Department of Physics starting in 1945, Institute Professor from 1965, and Institute Professor Emeritus from 1974. In addition to his research and teaching activities, Weisskopf played a major role in shaping the development of high-energy particle physics in the US and in Europe, serving as director general of the European Organization for Nuclear Research (CERN) between 1961 and 1965 and chair of the High Energy Physics Advisory Panel (HEPAP) from 1967 through 1973. Throughout his life he was involved in activities of many professional organizations including the Federation of Atomic Scientists, Pugwash Conferences, American Physical Society, American Academy of Arts and Sciences, and the Pontifical Academy of Science. The bulk of the collection dates from the 1960s through the 1990s, reflecting Weisskopf’s role as a physicist, educator, administrator, scientific statesman, and advocate of social and political causes.
