Yekusiel Yehudah Halberstam (Hebrew: יקותיאל יהודה הלברשטאם; January 10, 1905 – June 18, 1994) was a rebbe of the Hasidic dynasty of Sanz-Klausenburg.

Early life

Halberstam was born in 1905 in Rudnik, Austrian Galicia, in what is present-day Poland. He was a great-grandson (in the direct male line) of Chaim Halberstam, founder of the Sanz hasidic dynasty.[2] When he was 13 his father, Tzvi Hirsch Halberstam, the rabbi of Rudnik, died.

In 1925, Halberstam married his second cousin, Pessel Teitelbaum. She was the daughter of Chaim Tzvi Teitelbaum and therefore the sister of Moshe Teitelbaum as well as the niece of Joel Teitelbaum.
