The Mirrer Yeshivah is forever linked to its remarkable Mashgiach, Rabbi Yechezkel Levenstein zt”l, reverently known as “Reb Chatzkal”. His incomparable leadership preserved the spirit and unity of the yeshiva during the five war-torn Shanghai years, when the Yeshivah blossomed despite privation and danger. After the War, he became Mashgiach of Ponevezh and helped lead the spiritual rebirth of the Torah world. Rabbi Yitzchak Kasnett of Cleveland has written a biographical masterpiece, featuring memories from Reb Chatzkel’s family and talmidim, personal correspondence and never-before-published shmuessen, photographs and documents. Reb Chatzkel’s talmidim call the book a brilliant portrait of the luminous sage. A large second printing is on the way.
