Yitzchak Ruderman

Rabbi Yaakov Yitzchok Halevi Ruderman (Shushan Purim 1900,Daŭhinava - July 11, 1987) was a prominent Talmudic scholar and rabbi who founded and served as rosh yeshiva (yeshiva head) of Yeshiva Ner Yisroel in Baltimore.

He was born in Daŭhinava, in the Vilna Governorate of the Russian Empire (present-day Belarus), where his father, Rabbi Yehuda Leib Ruderman, was the rabbi. He studied in Yeshivas Knesses Yisrael in Slabodke, under the "Alter", Rabbi Nosson Tzvi Finkel, and the rosh yeshiva, Rabbi Moshe Mordechai Epstein, receiving semicha from the latter in 1926.

Among Rabbi Ruderman's distinguished colleagues in Slobodka were his second cousin Rabbi Yaakov Kamenetsky, Rabbi Reuven Grozovsky, Rabbi Aharon Kotler, and Rabbi Yitzchak Hutner.

In 1924, two years before receiving Smicha, he married into a rabbinical family.

In 1930, he joined his father-in-law, Rabbi Sheftel Kramer, at the latter's yeshiva in New Haven, Connecticut. In 1931, the Ruderman family moved to Cleveland, Ohio, where he served as one of the teachers at the Yeshiva.
