Aharon Yehuda Leib Shteinman (), also Shtainman or Steinman (November 3, 1914 – December 12, 2017), was a Haredi rabbi in Bnei Brak, Israel. Following the death of Yosef Shalom Elyashiv in 2012, he was widely regarded as the Gadol HaDor (Leader of the Generation), the leader of the non-Hasidic Lithuanian Haredi Jewish world. Along with several other rabbis, Shteinman is credited with reviving and expanding the appeal of European-style yeshivas in Israel. Early life Aharon Yehuda Leib Shteiman was born in Kamyenyets (Kaminetz), the son of Noach Tzvi and Gittel Faiga, and raised in Brest (Brisk), then part of the Russian Empire. He studied in Yeshivas Toras Chessed in Brest, headed by a rabbi known as the Imrei Moshe. He attended shiurim (Torah lectures) given by Yitzchok Zev Soloveitchik (the Brisker Rav). He also studied in Kletzk under Aharon Kotler. Upon reaching draft age in 1937, Shteinman was subject to the Polish draft, as Brest had come under the control of the newly established Polish state in the aftermath of the First World War. He and his close friend, Moshe Soloveitchik (a grandson of Chaim Soloveitchik), tried to evade the draft by starving themselves, but they were declared fit to serve by the draft officer. The two then fled with other Brisk students to Montreux, Switzerland, where they returned to Torah study in Yeshivas Etz Chaim. With the outbreak of World War II, the two became war refugees, and were incarcerated in the Schonenberg labor camp near Basel, where nearly all the inmates were Torah-observant. Shteinman and his friend were put to work laying roads, but due to his thin frame and short stature, he was released from manual labor and assigned to a desk job. Shteinman was the only member of his family to survive the war. Shteinman was known for his extremely modest lifestyle. His apartment, on Chazon Ish Street 5, was sparsely furnished, and had not been painted in many years. Until 2014, he slept on the same thin mattress that he had received from the Jewish Agency upon his arrival in Israel in the early 1950s. Rabbinic career During his first years in Israel, Shteinman and his family lived in Kfar Saba; his sons were sent to a cheder in Petah Tikva. Eventually, they relocated to Bnei Brak, where he headed the Ponevezh Kollel. In 1955, the Ponevezher Rav, Yosef Shlomo Kahaneman, opened the yeshivah
