After the destruction of European Jewry, the surviving remnant of Aleksander Hassidim asked Rabbi Yehuda Moshe to assume the leadership. He was a prolific writer and published a number of works, including Responsa Hashava Letava (Lodz, 1933) and another volume that contained two works: Kedushat Yitzhak and Nahalat Zvi (Jerusalem, 1952) – the former on the hassidic masters who precipitated Aleksander Hassidism, and the latter comments on the weekly Torah portion. Rabbi Yehuda Moshe also spoke to survivors and collated their recollections of Aleksander Torah in Meoran Shel Yisrael (Bnei Brak, 1971). His main collection of thoughts on the Torah and the festivals was published posthumously under the title Emunat Moshe (Bnei Brak, 1976-1991).
