Feshbach was invited to stay at MIT after he received his doctorate. He remained on the physics faculty for over fifty years. From 1967 to 1973, he was the director of MIT's
Center for Theoretical Physics, and from 1973 to 1983, he was chairman of the physics department. In 1983, Feshbach was named as an institute professor, the highest faculty honor at MIT.
Activism Feshbach was active in the
nuclear disarmament movement and was a founder and first chairman of the
Union of Concerned Scientists. In 1969, he participated in a protest against military research at MIT. He became concerned about the condition of scientists behind the
Iron Curtain, and worked to establish contacts between Western scientists and their
Eastern Bloc counterparts. Prof. Feshbach also championed the cause of
Andrei Sakharov and other Soviet
refuseniks. He first met Sakharov in the mid-1970s; Feshbach wrote about meeting Sakharov after his release from internal exile, in an article that appeared in
Physics Today. Feshbach was a strong believer in equality of opportunity, especially within the scientific community. He worked to increase the number of women and minority members in both the physics department and at MIT in general. In the early 1990s, he was chairman of the MIT faculty's Equal Opportunity Committee, which made recommendations for recruiting and hiring more women and minority faculty members. ==Death==
