Later, he was appointed head of the yeshiva, and his son, Rabbi Nissan Aharon Tucazinsky, subsequently ran it for over fifty years.
Tucazinsky agreed instead to lead the Etz Chaim yeshiva, but recommended his friend, Rabbi Tzvi Pesach Frank, for the position of judge.
It was under Tucazinsky's watch that Etz Chaim purchased its Jaffa Road property and moved there from its shared campus with the Hurva synagogue.
Tucazinsky was active in the foundation of new suburbs in Jerusalem and favoured the unification of all sections of the Jewish population.
[9] The Jerusalem municipality honoured his memory by naming the street Gesher HaChaim in the Mekor Baruch neighbourhood after the title of his book.
