Rav Yisrael Zev Gustman (1908-1991), a talmid of Rav Shimon Shkop in Grodno. Rav Gustman became rosh yeshiva of Ramailles when he was still a young man in Vilna. He served on the Beis Din of Rav Chaim Ozer Grodzinsky. In fact, he was the youngest dayan in the history of Vilna (at age 19). When the Nazis invaded Vilna, they stormed the yeshiva and beat Rav Gustman him until he collapsed. By a miracle he was spared, and he fled for his life. In 1961, Rav Gustman moved to Eretz Yisrael and transferred his yeshiva, Netzach Yisrael Ramailles, to the Rechavia section of Yerushalayim. Today its rosh yeshiva is his son-in-law, Rav Michel Berniker. One of his first students in Yerushalayim was Rav Moshe Francis, Rosh Kollel of the Chicago Community Kollel. Another talmid was Rav Moshe Lipke, Rosh Kollel of Y'kar Mordechai in Yerushalayim. Rav Gustman authored Kuntresei Shi'urim. (some say 18 Sivan)
