David Holloway is the Raymond A. Spruance Professor of International History, a professor of political science, and an FSI senior fellow. He was co-director of CISAC from 1991 to 1997, and director of FSI from 1998 to 2003. His research focuses on the international history of nuclear weapons, on science and technology in the Soviet Union, and on the relationship between international history and international relations theory. His book Stalin and the Bomb: The Soviet Union and Atomic Energy, 1939-1956 (Yale University Press, 1994) was chosen by the New York Times Book Review as one of the 11 best books of 1994, and it won the Vucinich and Shulman prizes of the American Association for the Advancement of Slavic Studies. It has been translated into seven languages, most recently into Chinese. The Chinese translation is due to be published later in 2018. Holloway also wrote The Soviet Union and the Arms Race (1983) and co-authored The Reagan Strategic Defense Initiative: Technical, Political and Arms Control Assessment (1984). He has contributed to the Bulletin of the Atomic Scientists, Foreign Affairs, and other scholarly journals.

Since joining the Stanford faculty in 1986 -- first as a professor of political science and later (in 1996) as a professor of history as well -- Holloway has served as chair and co-chair of the International Relations Program (1989-1991), and as associate dean in the School of Humanities and Sciences (1997-1998). Before coming to Stanford, he taught at the University of Lancaster (1967-1970) and the University of Edinburgh (1970-1986). Born in Dublin, Ireland, he received his undergraduate degree in modern languages and literature, and his PhD in social and political sciences, both from Cambridge University.

Lynn Eden is a Senior Research Scholar Emeritus. She was a Senior Research Scholar at Stanford University's Center for International Security and Cooperation until January 2016, as well as was Associate Director for Research. Eden received her Ph.D. in sociology from the University of Michigan, held several pre- and post-doctoral fellowships, and taught in the history department at Carnegie Mellon before coming to Stanford.

In the area of international security, Eden has focused on U.S. foreign and military policy, arms control, the social construction of science and technology, and organizational issues regarding nuclear policy and homeland security. She co-edited, with Steven E. Miller, Nuclear Arguments: Understanding the Strategic Nuclear Arms and Arms Control Debates (Ithaca, N.Y.: Cornell University Press, 1989). She was an editor of The Oxford Companion to American Military History (New York: Oxford University Press, 2000), which takes a social and cultural perspective on war and peace in U.S. history. That volume was chosen as a Main Selection of the History Book Club.

Eden's book Whole World on Fire: Organizations, Knowledge, and Nuclear Weapons Devastation (Ithaca: Cornell University Press, 2004; New Delhi: Manas Publications, 2004) explores how and why the U.S. government--from World War II to the present--has greatly underestimated the damage caused by nuclear weapons by failing to predict damage from firestorms. It shows how well-funded and highly professional organizations, by focusing on what they do well and systematically excluding what they don't, may build a poor representation of the world--a self-reinforcing fallacy that can have serious consequences, from the sinking of the Titanic to not predicting the vulnerability of the World Trade Center to burning jet fuel. Whole World on Fire won the American Sociological Association's 2004 Robert K. Merton Award for best book in science, knowledge, and technology.

Eden has also written on life in small-town America. Her first book, Crisis in Watertown (Ann Arbor: University of Michigan Press, 1972), was her college senior thesis; it was a finalist for a National Book Award in 1973. Her second book, Witness in Philadelphia, with Florence Mars (Baton Rouge: Louisiana State University Press, 1977), about the murders of civil rights workers Schwerner, Chaney, and Goodman in the summer of 1964, was a Book of the Month Club Alternate Selection.
