Haym Soloveitchik (born September 19, 1937) is an American Modern Orthodox rabbi and historian. He is the only son of Rabbi Joseph B. Soloveitchik. He graduated from the Maimonides School which his father founded in Brookline, Massachusetts and then received his B.A. degree from Harvard College in 1958 with a major in History. After two years of post-graduate study at Harvard, he moved to Israel and began his studies toward an M.A. and PhD at the Hebrew University in Jerusalem, under the historian Professor Jacob Katz. He wrote his Master's thesis on the Halakha of gentile wine in medieval Germany. His doctorate, which he received in 1972, concentrated on laws of pawnbroking and usury. He is known to many as Dr. Gra"ch (Hebrew: ד״ר גר״ח), after his great-grandfather for whom he is named, Rabbi Chaim Soloveitchik, who was known as the Gra"ch (Hebrew: גר״ח).
Soloveitchik's four step scholarly approach to learning has influenced many of his students. The approach can be traced back to the approach of the Gaon of Vilna. The first step is concentrating on the text. This follows the Vilna Gaon's approach of carefully amending the texts of both exoteric (the Talmud) and esoteric works (for instance, the Torat Kohanim, Tosefta, Avot de-Rabbi Natan, etc.). The second step is knowing the physical reality of the objects described. Third is the conceptual analysis proffered by Rishonim. At this point he introduces an important distinction between Rishonim, which are primary sources, and must be mastered, even if one has to struggle to understand them; and Achronim, which are secondary sources, which can be exploited (if you find good material, use it, but if you don't understand it, don't spend too much time on it). The fourth and final step is sevarah, creating the intellectual framework underpinning the Torah.
Soloveitchik taught at Hebrew University until 1984, and reached the rank of full Professor. During that period, he also taught at and served as Dean of the Bernard Revel Graduate School of Yeshiva University and served as a Rosh Yeshiva at its affiliate, the Rabbi Isaac Elchanan Theological Seminary. In the early 1980s, he left Hebrew University and began teaching at Yeshiva University on a full-time basis, serving as University Professor. He taught there until 2006, when he was appointed Merkin Family Research Professor in Jewish History and Literature.
Rabbi Michael Rosensweig wrote his Ph.D. (Debt Collection in Absentia: Halakhah in a Mobile and Commercial Age) under Prof. Soloveitchik, and is one of the few students mentored by him.
Haym Soloveitchik is acknowledged as a leading contemporary historian of Jewish law. Much of his work focuses on the interaction of Halakha with changing economic realities. Specifically, he has produced major studies of usury and pawnbroking and the multiple ramifications of Jewish involvement in the manufacture and sale of wine. A major theme of his writing is the positing of an essential integrity to the Ashkenazi Jewish legal process in its interaction with contemporary challenges.
Soloveitchik's oft-cited essay Rupture and Reconstruction, where he criticizes the triumph of the elite religion of the yeshiva world over the folk religion of American Orthodoxy, is viewed as a major statement on the state of contemporary Orthodox Judaism.
