Rabbi, teacher, and foremost authority in Jewish law (1895–1986). Feinstein was born in Russia and received his Talmudic education in the Yeshivot of Lithuania. He was Rabbi of the town of Luban in Russia from 1921 until 1937, at which date he emigrated to the USA where he served as the head of the Yeshivah Tiferet Yerushalayim in New York. Feinstein followed the methods of keen analysis of legal concepts as taught in the Yeshivot of Lithuania, with the emphasis on legal theory rather than on its application in practice. He published commentaries in this vein on a number of Talmudic tractates. But Feinstein's fame rests chiefly on his collections of Responsa under the name Iggerot Moshe, ‘Letters of Moses’. His decisions in these Responsa are widely held to be authoritative for the whole world of Orthodoxy.
