 With the passing of Rabbi Trop in 1928, the prominence of the yeshiva slowly diminished.Even with the appointment of two young Rosh yeshivas, Rabbi Baruch Feivelson (Trop's son-in-law) and Rabbi Mendel Zaks (son-in-law of the Chofetz Chaim), the yeshiva would never fully regain its famed status.Upon the death of Rabbi Baruch Feivelson in 1933, Rabbi Mendel Zaks became the sole Rosh yeshiva.
