Rebbetzin Rochel Lieff a”h

Jun 28, 2026·2 min read

It is with great sadness that Matzav.com reports the petirah of Rebbetzin Rochel Lieff a”h, who passed away at the age of 104.

Born in the historic Batei Machsah neighborhood of Yerushalayim in 1922, Rebbetzin Lieff was raised in an illustrious Yerushalmi family steeped in Torah and yiras Shamayim.

Her father was Rav Yaakov Leib Bergman, who was a son-in-law of Rav Yitzchok Shlomo Blau, a distinguished member of the renowned Blau family of Yerushalayim.

She later married Rav Yaakov Dovid Lieff zt”l, the longtime rov of Talmud Torah Tiferes Yisroel/The Avenue O Jewish Center in Brooklyn. Together, they built a home that became a beacon of Torah, producing children who continue to have a profound impact on the Torah world. Rav Yaakov Dovid was niftar 28 years ago.

Among her distinguished children are Rav Moshe Tuvia Lieff, rov of Agudath Israel Bais Binyomin on Avenue L in Flatbush, and Rav Eliezer Simcha Lieff, rosh yeshiva of Yeshiva Gedolah of South Monsey. She was predeceased by her son, Nochum Shlomo Lieff, who passed away at a young age.

Although she enjoyed a successful career as a mathematics professor at Brooklyn College, Rebbetzin Lieff never allowed her professional accomplishments to overshadow the central mission of her life. She remained steadfastly devoted to her family’s growth in Torah, providing constant encouragement and support to her husband in his rabbanus and to her sons as they pursued lives of Torah learning and leadership. Those who knew her saw a woman who skillfully balanced intellectual achievement with deep dedication to her role as the foundation of a home built upon Torah.

Throughout more than a century of life, Rebbetzin Lieff witnessed—and helped shape—the remarkable growth of the postwar Torah world. From her roots in Yerushalayim to the flourishing kehillos of Brooklyn and Monsey, she stood at the center of a family whose impact has been profound.

The levayah will take place today at 12 noon at Yeshiva Gedolah of South Monsey, located at 260 Saddle River Road in Airmont, NY. Following the levayah, the aron will be flown to Eretz Yisroel for kevurah there.

Yehi zichrah baruch.
