Joseph B. Soloveitchik

Joseph Ber Soloveitchik ( ''Yosef Dov ha-Levi Soloveychik''; February 27, 1903 – April 9, 1993) was a major American Orthodox rabbi, Talmudist, and modern Jewish philosopher. He was a scion of the Lithuanian Jewish Soloveitchik rabbinic dynasty.

As a ''rosh yeshiva'' of Rabbi Isaac Elchanan Theological Seminary (RIETS) at Yeshiva University in New York City, The Rav, as he was known, ordained close to 2,000 rabbis over the course of almost half a century. Some Rabbinic literature, such as sefer Shiurei HaGrid, refers to him as הגרי"ד, short for "The great Rabbi Yosef Dov".

He is regarded as a seminal figure by Modern Orthodox Judaism and served as a guide and role-model for tens of thousands of Jews, both as a Talmudic scholar and as a religious leader. Provided by Wikipedia
