Editing Rabbi Zalman Shimon Dvorkin (section)

== Later Years ==
In 1954, he moved to Pittsburgh and served as the Rabbi of Anash there. Around 1964, he was brought to serve as Rabbi of the large Chabad community in Crown Heights, and together with Reb Shmuel Levitan and [[Rabbi Eliyahu Yeichil-Simpson|Reb Eliyahu Simpson]] served as a posek in [[770 Eastern Parkway - Chabad World Center|770]].

He was appointed as "Rosh Kollel" in the Kollel under the secretariat of the Rebbe.

His wife Rebbetzin Tzvia passed away on the night of Shabbos, 15th of Iyar 1976.

During his illness, he once spoke with the Rebbe, and the Rebbe told him to ask for whatever he wanted. Understanding this was an auspicious time, he asked for Moshiach's coming (rather than his own healing).

He passed away from his illness on Motzei Shabbos Parshas Ki Sisa, 17th of Adar 1985, near midnight after asking for a glass of water. The Rebbe participated in his funeral which took place the following day.

He did not leave any children.

After his passing, elections were held for the neighborhood rabbis. In these elections, the following distinguished rabbis were chosen to serve: Rabbi Yehuda Kalman Marlow, [[Rabbi Avrohom Osdoba|Rabbi Avraham osdoba]], and Rabbi Avraham Yosef Heller.
