About Ephraim Zalman Margolioth
Ephraim Zalman Margolis (December 19, 1762–August 24, 1828) (Hebrew: אפרים זלמן בן מנחם מרגליות) was a Galician rabbi born in Brody.
He received his Talmudic education at different yeshivas, in which he distinguished himself for the acuteness of his intellect and for his astonishing memory. His correspondence with Ezekiel Landau and other leading Talmudists soon gained for him a high reputation. He established a banking-house which proved so successful that within a short time he became quite wealthy. In 1785 he published his responsa entitled Bet Hadash ha-Hadashot, and in the following year the rabbis of Brody elected him one of their number. Being of independent means, he opened in his house a yeshivah of which he was the head; several of his pupils became eminent rabbis.
He published the following works:
Bet Efrayim (2 vols., Lemberg, 1809-10), commentary on parts of the Shulchan Aruk, Yoreh De'ah:
בית אפרים - חלק א
בית אפרים - חלק ב
