Rabbi Ephraim Oshry was a posek who served as the spiritual leader of the Kovno Ghetto during the Holocaust. He is known for his responsa written during this period, which he buried in tin cans and later published in a five-volume work titled She’eilos Uteshuvos Mima’amakim. After the war, he founded the Me'or ha-Golah yeshiva for child survivors in Rome and later served for over 50 years as the rabbi of Beth Hamedrash Hagadol on the Lower East Side of New York.
