Teitelbaum is the third 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 the 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, with the influential Yiddish newspaper
Der Yid being published by his followers. In 2007,
Newsweek named him the 15th most influential rabbi in the United States. ==Satmar succession feud==
