Shlomo Yosef Zevin (Hebrew: שלמה יוסף זווין) (born 1888; died 28 February 1978) was one of the most prominent Orthodox, Religious Zionist rabbis of the 20th century. He founded the Encyclopedia Talmudit, a Hebrew Halachic Encyclopedia, of which he was chief editor until his death.
Shlomo Yosef Zevin was born in 1888 in Kazimirov (near Minsk), where his father, Aharon Mordechai, served as rabbi. The younger Zevin’s education was a combination of both “Litvishe” (Lithuanian) and Hasidic influences; he studied first in the Yeshiva of Mir under Rabbi Eliyahu Baruch Kamai (where he was the study partner of Rabbi Yechiel Yaakov Weinberg) and then in Bobruisk, under Rabbi Shemaryahu Noach Schneerson, then leader of the Kapust branch of the Chabad hasidic dynasty. Zevin was ordained by Rabbi Schneerson, Rabbi Yosef Rosen (the Rogatchover Gaon), and Rabbi Yechiel Michel Epstein (author of Aruch Hashulchan).
At a young age Rabbi Zevin was appointed rabbi of his birthplace, Kazimirov, and served as editor of the journal "Shaarei Torah." He later served as rabbi of Klimon and Novozybkov. He took an active role in the underground struggle to preserve Jewish observance in Soviet Russia after the Communist Revolution; this effort was headed by Rabbi Yosef Yitzchok Schneersohn. Beginning in 1921, he edited a Torah journal, Yagdil Torah, together with Rabbi Yehezkel Abramsky of Slutsk; for this crime he was imprisoned by the Communist authorities. He founded Orthodox Jewish journals that dealt with problems of the time.
