Joel Teitelbaum (Hebrew: ???? ??????????, Ashkenazi pronunciation: IPA: [j?jl? te?t?lb?jm]; 13 January 1887 – 19 August 1979) was the founder and first Grand Rebbe of the Satmar dynasty.
A major figure in the postwar renaissance of Hasidism, he espoused a strictly conservative and isolationist line, rejecting modernity.
Teitelbaum was a fierce opponent of Zionism, which he decried as inherently heretical.
His role as a Jewish community leader in Transylvania during the Holocaust remains controversial.
