Editor’s note: Rabbi Dr. Henry Horwitz passed away on May 15, in Jerusalem. A graduate of Yeshiva College, RIETS, the Bernard Revel Graduate School and the Massachusetts Institute of Technology where he earned a doctorate in molecular biology, Rabbi Dr. Horwitz was a close talmid of the Rav, Rabbi Joseph B. Soloveichik, zt”l, as well as his brother, Rabbi Ahron Soloveitchik, zt”l. Rabbi Dr. Horwitz is survived by his wife, Frieda Horwitz, and his five children, Yossie (and Ayala) Horwitz (our Jewish Link wine contributor, of Teaneck), Serylle Horwitz- (and Yair) Hakak, Shlomo (and Sarra) Horwitz, Yeshayahu Horwitz, and Shmuel (and Asnat) Horwitz along with his 12 grandchildren.

Although he had semikhah from Rav Yosef Dov Soloveitchik, zt”l, and a doctorate from M.I.T., you had to be a close friend of Henry Horwitz, z”l, to know about either. He also did not speak about his family’s distinguished record of support to Torah Umesorah, the OU, National PTA, Maimonides School and more. Instead, he advanced that record as president of Yavneh, the National Association of Religious College Students, as president of YU Alumni in Israel, and as a leading member of the community in Brookline, then in Jerusalem. He and his wife Frieda welcomed guests regularly.

His integrity, loyalty, and sense of responsibility were remarkable. While his vocation was arranging conferences in Israel, his avocation was learning Torah. He attended Rav Aharon Lichtenstein’s zt”l shiurim at the Gruss Kollel for many years. He maintained a chavrusa. I had the good fortune to learn together with him in the Rav’s shiur. Our sons followed that tradition of learning together and now our granddaughters are learning together as well.

These hespedim by Dr. Tovah Lichtenstein and Rabbi Saul Berman give a fuller picture of what the Orthodox community has lost with his sudden passing.

Rabbi Yosef Blau is senior mashgiach ruchani at Yeshiva University.
