Enter the world of Rabbi Moshe Feinstein (1895–1986), the Russian-born giant of Jewish Law (Halakha) who, from his modest study on New York's Lower East Side, became arguably the most influential Posek (legal decisor) for Orthodox Jewry worldwide in the 20th century. Fleeing Soviet oppression in 1937, he assumed the leadership of Mesivtha Tifereth Jerusalem and dedicated his life to applying traditional Talmudic principles to the unprecedented technological and social challenges of the modern era. His voluminous collection of legal rulings, Igros Moshe ("Letters of Moshe") , tackled everything from medical ethics (like defining brain death and advising on heart transplants) to new technologies (like using electricity on Shabbat) and American social issues (like labor disputes and dairy supervision). Discover how his characteristic blend of profound scholarship, pragmatic flexibility, and unwavering traditionalism set the definitive halakhic course for generations of Orthodox Jews across the globe.
