Rabbi Chaim Mordechai Katz was a rosh yeshiva who, after escaping the destruction of European Jewry, co-founded and led the transplanted Telshe Yeshiva in Cleveland. Together with his brother-in-law, Rabbi Eliyahu Meir Bloch, he re-established the yeshiva in 1941 and served as its head from 1954 until his passing. He was also a founder of Zeirei Agudath Israel in Lithuania and a member of the Moetzes Gedolei HaTorah in America.
