In 1945, Kronglas arrived in Canada with a group of refugees, and was invited to serve as the Mashgiach Ruchni of Ner Yisroel where he remained until his death on Saturday, December 16, 1972. He was also a
Maggid Shiur, and lectured for the most advanced students. Kronglas also developed many of the
liturgical customs of the yeshiva, especially as they relate to the
High Holy Days. Every year on his
Yahrzeit, a lecture is delivered in Ner Yisroel based on his Talmudic discourses. == Books ==
