Sagan was the recipient of the National Academy of Sciences William and Katherine Estes Award in 2015, for his pioneering work addressing the risks of nuclear weapons and the causes of nuclear proliferation. The award, which is granted triennially, recognizes “research in any field of cognitive or behavioral science that advances understanding of issues relating to the risk of nuclear war.” In 2013, Sagan received the International Studies Association’s International Security Studies Section Distinguished Scholar Award. He has also won four teaching awards: Stanford’s 1998-99 Dean’s Award for Distinguished Teaching; Stanford’s 1996 Hoagland Prize for Undergraduate Teaching; the International Studies Association’s 2008 Innovative Teaching Award; and the Monterey Institute for International Studies’ Nonproliferation Education Award in 2009.


Kenneth N. Waltz Before completing his Ph.D. at Columbia University in 1954, Waltz served in the United States Army during the Second World War and the Korean conflict.  He was a member of the Columbia University faculty (1953-1957), and he subsequently taught at Swarthmore College, Brandeis University, and the University of California, Berkeley (1971-1994), before returning to Columbia and the Institute in 1997. Waltz was a research associate with the Center for International Affairs at Harvard University on several occasions, and with the Department of War Studies, Kings College, University of London.  He taught at the London School of Economics, the Australian National University, Peking University, Fudan University, the United States Air Force Academy, and the University of Bologna.  Waltz was President of the American Political Science Association 1987-1988. He has received honorary doctorates from Copenhagen University,  Oberlin College, Nankai University, Aberystwyth University, and most recently  from the University of Macedonia in Saloniki, Greece, which he accepted in person in the spring of 2011. Waltz’s books include Man, the State, and War: A Theoretical Analysis (Columbia University Press, 1954, 1959, 2001), Theory of International Politics (Addison-Wesley, 1979), and Realism and International Politics (Routledge, 2008).  The third, updated edition of The Spread of Nuclear Weapons: A Debate (W.W. Norton, 1995, 2003), which he wrote with Scott Sagan, was published in 2012. Waltz was also the author of numerous journal articles and book chapters. His most recent articles included: “Why Iran Should Get the Bomb” in Foreign Affairs (July/Aug 2012); “The Great Debate,” an exchange with Scott Sagan on nuclear weapons in The National Interest (Sep-Oct 2010);  and with then-Columbia University Ph.D. candidate Mira Rapp-Hooper (now at CNAS), “What Kim Jong-Il Learned from Qaddafi’s Fall: Never Disarm,” The Atlantic (online, October 24, 2011). Waltz remained active in the life of the Institute as a Senior Research Scholar until his death on May 13, 2013 at the age of 88. At the time of his death he was still advising students, doing research on nuclear deterrence, and revisiting canonical works of international relations theory. In his later years, Waltz divided his time between homes on the Upper West Side of Manhattan and Harborside, Maine.
