Rav and Rebbe

"The two great Jewish sages of the past century, Rabbi Yosef Dov Soloveitchik - The Rav - YU and Rabbi Menachem Mendel Schneerson - The Rebbe - Chabad grew up in Russia. They both studied at the University of Berlin and each became a leading figure in post-Holocaust Judaism in America. Read now, for the first time ever, about their unique relationship and respect for each other. Understand that although the Rav was a father-figure for Lithuanian Judaism and the Rebbe, the world's greatest Chasidic master, nevertheless their message was universal."-- Amazon.com.
