This past Motza’ei Shabbos, the yeshivah world was thrown into mourning for the third time in a week with the petirah of HaRav HaGaon Yechiel Yitzchak Perr, ztk”l, 89. Rabbi Perr was the founder and Rosh HaYeshivah at Yeshiva Derech Ayson, Yeshiva Far Rockaway, my alma mater. Though our interactions were few over my high school career, each was steeped in deep meaning and lesson, be it in the beis hamesdresh or the yeshivah office where I often found opportunities. Rabbi Perr relied on the wisdom and foresight of his partner at the yeshivah, HaRav Aharon Brafman zt”l, the pioneering menahel. Together, they changed the landscape of Far Rockaway and built a community where hundreds of alumni settled. His loss is incalculable for the Torah community and as the preeminent Torah authority at the helm of the Far Rockaway community, Rabbi Perr made an indelible mark influencing thousands of bnei Yisrael with his unmatched brilliance.
