Aryeh Tzvi Frumer

Rav and rosh yeshiva At age 18 Frumer married his cousin, Esther Schweitzer, daughter of Yehuda Shraga Schweitzer of Lvov, and was supported by his father-in-law in the latter's home in Mysłowice so he could continue his Torah studies.

During World War I the city of Sochaczew and the yeshiva were destroyed in a fire, and Frumer moved with his family to Warsaw. A while later, Frumer was nominated to be the Rav of Zawiercie, but lost to another candidate, and moved with his yeshiva to nearby Sosnowiec. With each move, he gained more students and more admirers from surrounding towns, leading to the decision of the directors of Yeshivas Chachmei Lublin, the premier yeshiva of Poland,

Warsaw Ghetto After the Germans closed down Yeshivas Chachmei Lublin, Frumer fled to Warsaw and moved into the Warsaw Ghetto, where he continued to study Torah and produce chidushim (original Torah insights). As the Nazi deportations increased in frequency, Frumer and his Rebbe joined other Torah scholars who disguised themselves as workers in a large shoe factory owned by Fritz Schulz. Frumer worked in the Wooden and Fur Shoe section, which produced wooden clogs and fur slippers and supplied footwear for the German soldiers on the Russian front.

Twelve days after the Warsaw Ghetto Uprising, Frumer and his family were deported with other Jews to the Majdanek concentration camp.
