Yechiel Michel ben Tzvi Hirsch. LeZecher LeYisrael [commentary to Pirkei Avoth and novellae on Talmud tractates Baba Metziah, Gittin and Chullin]

The author records here that he studied and prayed in the Beth Hamidrash of the Vilna Gaon, whose “fondness and affection did not leave me.” After remaining a disciple of R. Chaim of Volozhin for seven years, he then served as one of the first founding Roshei Yeshiva of Volozhin. He later established his own Yeshiva in Minsk and thanks R. Chaim for guiding him in the appropriate manner by which to administer a Yeshiva. See M. Tzinowitz, Eitz Chaim-Toldoth Yeshivath Volozhin (1972) pp. 92, 441-46.
