The JIH and many members of its Board of Editors mourn Richard H. Ullman, a longtime member of that Board and the David E. Bruce Professor of International Affairs, Emeritus, at Princeton’s Woodrow Wilson School of Public and International Affairs. Ullman died after a long struggle with Parkinson’s disease and after a lifetime of well-praised scholarship on Anglo-Soviet diplomatic history, on American foreign policy decision-making, on Cold War nuclear projects, and on dozens of other path-breaking subjects. He edited Foreign Policy, served on the U. S. State Department’s Policy Planning Staff and the New York Times editorial board, and seriously mentored generations of students. He was a great friend and advisor to the JIH.
