He was born in the hamlet of Kalushkove, Lithuania, in 1891. Shortly afterwards his family moved to the village of Dolhinov where he grew up. He studied in Minsk and then for 21 years in Slabodka yeshiva under Rabbi Nosson Tzvi Finkel. It was there that he met his lifelong friend Rabbi Aharon Kotler, who later founded the Lakewood yeshiva. His younger cousin, Rabbi Yaakov Yitzchak Ruderman, also grew up in Dolhinov.

From 1948 to 1968 he headed Mesivta Torah Vodaath in Brooklyn, New York. Along with Rabbi Moshe Feinstein, he led American Jewry in issues of halachic and spiritual guidance until 1986, when both men died.
