Екушель Иехуда Тейтельбаум: Один из лидеров Сатмара в Вильямсбурге

One of the two Grand Rebbes of Satmar

Yekusiel Yehuda Teitelbaum (III), known by the Yiddish colloquial name Zalman Leib (born 23 December 1951), is one of the two Grand Rebbes of Satmar. He leads the dynasty's Williamsburg, Brooklyn faction, which is based at the community's central Congregation Yetev Lev D'Satmar on Rodney Street there. He is the dean of a Satmar yeshiva in Queens, New York.

Teitelbaum is the second son born to Moshe Teitelbaum, the Grand Rebbe of the Satmar Hasidim, in Williamsburg, Brooklyn. His older brother is Aaron. Early on, Teitelbaum became the rabbi of the Sighet synagogue in nearby Borough Park, which had once been his father's synagogue. He later became the rabbi of the Satmar Hasidim in Jerusalem. In May 1999, he was designated by his father to lead the Williamsburg congregation at 152 Rodney Street, which was seen as a signal that Teitelbaum was to become Chief Rabbi after his father's death. Additionally, he controls approximately ten smaller synagogues and gender segregated schools in Williamsburg alone—with many more elsewhere—which cater to some 10,000 students. He oversees several charitable funds and large organizations, and the influential Yiddish newspaper Der Yid is published by his followers. In 2007, Newsweek named him the 15th most influential rabbi in the United States.

Prior to May 1999, it was generally assumed that Satmar would be led by Aaron after the death of their father, since he was the older brother. Aaron was his father's representative in communal affairs, and assumed his father's responsibilities while he was traveling. By that time, Aaron's supporters already controlled all of the assets in the community stronghold of Kiryas Joel, New York. Following the 2023 Hamas invasion of Israel, Teitelbaum condemned the activities of Neturei Karta.

In October 2020, during the COVID 19 pandemic, a whistleblower reported to authorities that a wedding planned to attract 10,000 worshippers at the Williamsburg synagogue, in contravention of regulations regarding public gatherings. Governor Andrew Cuomo directed that the wedding of Teitelbaum's grandson could not proceed on the basis of a health order that read " the owners or occupants of the venue to immediately cancel or postpone any event in excess of the 50 person gathering limit."

Teitelbaum married Chaya Sarah, the daughter of the previous Bistritzer Rebbe of Brooklyn. Teitelbaum's sons lead both the Borough Park and Jerusalem congregations that were previously administered by him.
