Yechiel Yaakov Weinberg

Yechiel Yaakov Weinberg (1884–1966) was an Ashkenazi Orthodox rabbi, posek ("decisor" of Jewish law) and rosh yeshiva. He is best known as the author of the work of responsa Seridei Eish.

Weinberg was considered a genius in his time - with mastery over both Torah and secular subjects. An insightful and introspective individual, his varying interests in Talmud, musar, Hebrew literature, Russian language, and general academia make him one of the best representatives of the tumultuous intellectual trends present in his period.
