Moshe Zvi Giterman of Savran (1775–1837) was the first Rebbe of Savran (Hasidic dynasty) and an influential Hasidic leader in western Ukraine, whose following numbered in the thousands.
Among other hasidic melodies specific to Savran, Rebbe Moshe Zvi Giterman composed a very inspiring version of B'nei heicholo that is traditionally sung at Seudah Shlishit.
