Brisker Rav
Rabbi Yitzchok Zev Soloveitchik (1886–1959), known as the Brisker Rav, was a towering figure in 20th-century Torah scholarship. He led the Brisk Yeshiva in Jerusalem, championed the Brisker method of Talmud study, and upheld uncompromising halachic standards. A staunch opponent of Zionist politics, he shaped Haredi ideology profoundly.
