Yekusiel Yehuda Teitelbaum (III), known by the Yiddish colloquial name Zalman Leib (born 23 December 1951),[1] is one of the two Grand Rebbes of Satmar.

He oversees several charitable funds and large organizations, with the influential Yiddish newspaper Der Yid being published by his followers.

[citation needed] 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.

[5] Subsequently, Aaron's followers established a parallel congregation in Williamsburg by erecting a dedicated synagogue on Hooper Street.

[7] In October 2020, during the COVID-19 pandemic, a whistleblower reported to authorities that a wedding was planned to attract 10,000 worshippers at the Williamsburg synagogue,[8] in contravention of regulations regarding public gatherings.

[9] 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.
