Erich Fromm (March 23, 1900 – March 18, 1980) was an American psychoanalyst, social philosopher, Marxist proponent, and Socialist Party of America member. He was born in Germany, and earned his Ph.D. in 1922 from Heidelberg. He became a citizen of the USA in 1940. His most influential book was Escape from Freedom (1941). His final book To Have or to Be? (1976) posits materialism's link to violence and "being" or love as the basis of productivity.
In 1957, Coretta Scott King, Albert Schweitzer and others founded the anti-war National Committee for a Sane Nuclear Policy or SANE (now the activist group Peace Action) based on the title of Fromm's book The Sane Society.
