1878-1965. Austrian-born Israeli philosopher,
a Zionist and advocate of the reappraisal of
ancient Jewish thought in contemporary terms.
His book I and Thou 1923 posited a direct
dialogue between the individual and God; it
had great impact on Christian and Jewish
theology. When forced by the Nazis to abandon
a professorship in comparative religion at
Frankfurt, he went to Jerusalem and taught
social philosophy at the Hebrew University
1937-51.
