Zalman Teitelbaum

Yekusiel Yehuda III Teitelbaum, known by the Yiddish colloquial name Zalman Leib (born 23 December 1951), is one of two Grand Rebbes of Satmar, and the son of Grand Rabbi Moshe Teitelbaum, the late Rebbe of the Satmar Hasidim. He is the son-in-law of the previous Bistritzer Rebbe of Brooklyn. He is currently one of the two Grand Rebbes of Satmar, with his faction being based in central Satmar congregation in Williamsburg, and the Dean of a Satmar yeshiva in Queens.

Prior to taking up his position in Williamsburg, Rabbi Teitelbaum was the rabbi of the Satmar Hasidim in Jerusalem. Before that, he was the rabbi of the Sighet synagogue in Boro Park, which had once been his father's synagogue. Presently, both of those synagogues are led by sons of Rabbi Zalman Teitelbaum. He is currently the Rabbi of the central Satmar synagogue in Williamsburg, at 152 Rodney Street. Additionally, he controls approximately ten smaller synagogues, as well as separate schools for boys and girls, in Williamsburg alone, and many more elsewhere which cater to over 10,000 students. He oversees several charitable funds and large organizations. The influential Yiddish newspaper Der Yid is published by his followers.

In 2007, Newsweek named him the 15th most influential rabbi in America.
