Paul Doty, the founder of Harvard Kennedy School‘s Belfer Center for Science and International Affairs, died Dec. 5 at the age of 91.

Graham Allison, former dean of the Kennedy School and director of the Belfer Center, advised colleagues of Doty’s passing: “Paul was a great man who had a great life and who made huge contributions to many of us personally, to the institutions of which we are a part, and to the purposes we care about. As we celebrated his 90th birthday in June 2010 I noted that he was a ‘serial institutional builder,’ having ‘entrepreneured’ not only today’s Belfer Center for Science and International Affairs, but prior to that Harvard’s biochemistry department. Paul was a lifelong peacemaker, building bridges between Soviet and American scientists and promoting nuclear disarmament since the 1950s — work that helped the Pugwash Conferences earn the Nobel Peace Prize in 1995.”
