Pugwash Conferences on Science and World Affairs
The Pugwash Conferences on Science and World Affairs won the Nobel Peace Prize in 1995. Feld was a leader in these conferences, serving as U.S. Chairman from 1963 to 1973 and as International Chairman from 1973 to 1978. It was in this role that he attracted the anger of Richard Nixon's White House. He was eleventh on Nixon's list of enemies, a fact that pleased him tremendously.
