Esteemed Jewish philosopher, social critic and theologian, Martin Buber is known for his classic I and Thou (1932) which discussed the relationship between God and man. As Nazism rose in Germany, Buber became director of the German national Jewish adult education organization, but in 1938 he left Germany for Palestine, where he became chair of social philosophy at the Hebrew University of Jerusalem. Among many other works, his studies of Hasidism are remembered as the first popular introduction of the movement to the West. Bibliography: Berry, Donald L., Mutuality: The Vision of Martin Buber.
