Martin Buber (1878 1965), is among the foremost twentieth-century philosophers of human relations and Jewish thought. He is best known for his revival of popular interest in Hasidism and his philosophy of dialogue, a form of existentialism centered on the distinction between the I-Thou and I-It relationships. His work on Hasidic thought, Zionism and religious philosophy continues to influence both the academic study of Judaism and religious thinking more broadly. He also inspired the trend toward neo-Hasidism among modern Jews. His books include I and Thou, Tales of the Hasidim, On Judaism and many others.
