It is with great sadness that reports the petirah of Rav Avrohom Erlanger zt”l, rosh yeshiva at Yeshivas Kol Torah in Yerushalayim. He was 90 years old.

Rav Erlanger contracted the coronavirus on Erev Yom Kippur and was hospitalized since then at Shaare Tzedek Medical Center in Yerushalayim. He passed away overnight.

Rav Erlanger was one of the senior gedolei Torah and marbitzei Torah of Eretz Yisroel. He was known for his magnum opus, Birkas Avrohom, a set of many volumes on all of Shas.

Rav Erlanger was born in Switzerland on the 2nd of Teves, a son of Rav Shimshon Refoel Erlanger, and a grandson of Rav Avrohom Erlanger, who was one of the leaders of the chareidi community in Switzerland.

Rav Erlanger was one of the first talmidim of Rav Yosef Dov Soloveitchik zt”l.

He married his wife, Rebbetzin Miriam, a daughter of Rav Chaim Yosef Jakobowicz, who was a rebbi at the Frankfurt Yeshiva.

After immigrating to Eretz Yisroel, he was appointed to serve as a R”M at Yeshiva Kol Torah in the Bayit Vagan neighborhood of Yerushalayim, where he taught thousands over the years.

When he reached the age of seventy, he decided to “retire” from the yeshiva in order to study areas of Torah that are not taught in the yeshiva sefer, but he continued to give shiurim, vaadim and chaburos.

He would also deliver a shiur every leil Shabbos at the Kamenitzer Yeshiva in Yerushalayim, and also at the Mir Yeshiva.

Rav Erlanger was predeceased by a daughter, Mrs. Dina Brendel Pragand his daughter-in-law, Mrs. Chaya Rivka Erlanger, wife of his son, Rav Yisroel Meir.
