Born in Frankfurt-am-Main, Erich Fromm (1900-1980) studied sociology and psychoanalysis. In 1933, he emigrated as a member of the Frankfurt School of social thinkers to the United States, moved to Mexico in 1950, and spent his twilight years between 1974 and 1980 in Switzerland. His books Fear of Freedom (1941) and The Art of Loving (1956) made him famous. Other well-known books are Marx's Concept of Man, Beyond the Chains of Illusion, and The Essential Fromm. Rainer Funk is the author of "Erich Fromm: The Courage to be Human," as well as the editor of the multivolume German edition of Fromm's complete works.
