Eliezer Zusia Portugal (17 October 1898–18 August 1982) was the first Rebbe of Skulen. He was revered by his followers in Russia, Romania, Israel, and the United States for his personal warmth and his care for hundreds of Jewish youth and war orphans, whom he personally adopted as his own children. He established the Skulener dynasty in America in the 1960s. His only biological son, Rabbi Yisroel Avrohom Portugal, succeeded him as Rebbe.
