Rabbi Ephraim Oshry

Rabbi Ephraim Oshry was a halakhic authority renowned for his responsa issued during the Holocaust. He authored the multi-volume *Mi-Maamakim*, containing rulings on Jewish practice under Nazi oppression in the Kovno ghetto, which he preserved by burying scraps of paper and later expanded into formal teshuvot. His works also include *Divrei Efraim*, *Oẓar ha-Pesaḥ*, *Imrei Efraim*, *Hasidei Efraim*, and the memoir *Khurbn Lite* on the destruction of Lithuanian Jewry.
