In 1957 Erich Fromm—renowned psychologist and former faculty member—co-founded the National Committee for a Sane Nuclear Policy, or SANE, which took its name from his 1955 book, The Sane Society. It became the largest and most influential nuclear disarmament organization in the United States. The Limited Test Ban Treaty of 1963, which halted atmospheric nuclear tests, is counted as one of the organization’s greatest achievements.
