Feinstein, Mosheh

views updated

Feinstein, Mosheh (1895–1986). Orthodox Jewish rabbi. Feinstein was a leading halakhic authority (posek). Many of his responsa covered questions raised by modern science and technology, and also by the Holocaust and by air disasters, which magnified the problems of agunah (a woman whose husband's fate is unknown). His responsa are published in Iggerot Mosheh (7 vols).
