Rav Mordechai Rimer was Mashgiach Ruchoni of Yeshiva Kochav MiYaakov. Born in Munkacz to Rav Binyomin, one of the most prominent Kalushitz Chassidim who was the Rosh HaKohol of the Sanz Bais Medrash in the city, young Mordechai grew up in the home of his grandfather, Rav Arye Leib Rimer, one of the most prominent Sanzer Chassidim in Kashow. In the winter of 1944, he was taken from the Yeshiva of Munkacz, along with his entire family, to the ghetto, and on Rosh Chodesh Sivan of that year they were all deported to Auschwitz. Although his entire family was murdered, he lived there until its liberation. After the war, he learned at the Chevron Yeshiva under Rav Meir Chodosh. After his marriage in 1950, he learned in the Chevron kollel for another twelve years. At that time, he began to deliver a shiur for ba’alei batim bnei Torah in the Achva shul, a shiur that he continued to deliver for forty-five years. In 1962, the Gaon of Tchebin invited him to be a Maggid Shiur and Mashgiach in his Yeshiva, and for thirty-eight years Rav Mordechai assumed responsibility for the chinuch of the Yeshiva’s students. During the Yomim Noro’im he regularly served as a ba’al tefilla at the Tchebin Yeshiva.
