Roger Fisher (born May 28, 1922) is Samuel Williston Professor of Law emeritus at Harvard Law School and director of the Harvard Negotiation Project.
Throughout the 1980s and 1990s, Roger Fisher and his colleagues taught courses on negotiation and conflict management at Harvard, but they also worked as advisors on real negotiations and conflicts of all types, worldwide; including peace processes, hostage crises, diplomatic negotiations, and commercial and legal negotiations and disputes.
In 2005, Fisher published one of several follow-ups to Getting to YES called Beyond Reason: Using Emotions as You Negotiate (with co-author Daniel Shapiro, a Harvard psychologist). Beyond Reason identifies five "core concerns" that everyone cares about: autonomy, affiliation, appreciation, status, and role. The book shows how to use the core concerns to stimulate helpful emotions in negotiations ranging from the personal to international. In Beyond Reason, Fisher documents many of his first-hand experiences negotiating around the world, from his involvement in negotiating the Iran hostage crisis to his advisory role in helping Jamil Mahuad, President of Ecuador (1998-2000), resolve a long-standing international border dispute.
Fisher received his Bachelor's degree from Harvard in 1943 and his law degree from Harvard Law School in 1948. He taught at Harvard from 1958-1992.
In 1984, Fisher founded the Conflict Management Group (CMG) in Cambridge, Massachusetts. CMG specialized in facilitating negotiations in conflicts worldwide. CMG merged with the Mercy Corps humanitarian group in 2004. He is a member of the Council on Foreign Relations and of the International Editorial Board of the Cambridge Review of International Affairs.
