Rav Nosson Tzvi Finkel, ZT"L
I did not merit to know the Rosh Yeshiva of the Mir, Rav Nosson Tzvi Finkel ZT"L, who passed away early this morning. Nevertheless, I knew the Yeshiva he headed - "The Mir", as they say - as the premier Yeshiva in Israel. The majority of the rabbis of the Yeshiva I attended in Israel learned at The Mir.
