Ha’Gaon Rabbi Aharon Moshe Mi’geza Zvi (1775-1845) was an Ish Elokim and one of the talmidim of the Chozeh of Lublin. He was the leader of the Chasidishe Kehila in Jerusalem. Reb Aharon Moshe was born in Brod and was one of the famed members of the Kloiz in Brod, where he learned all the facets of the Torah. Later, he became a talmid of the Chozeh and the Saraf of Strelisk. In 1839, he moved to EY, settled in Yerushalayim, and established the Chasidishe Kehilla of Yerushalayim. (At that time, the Chasidishe Kehilla’s in EY were in Teveria and Tzefas, where the Tzadikim Rabbi Mendele Vitebsker and Rabbi Avraham Kalisker settled)

He was known as a Ba’al mofes and revealed many sisrei Torah to the world.


Ha’Gaon Ha’Mekubal Rabbi Nathan Kornel, author of Teshuvos Ha’Gaonim (1810-1900), was born in Amsterdam. In his youth, he studied in his city under the illustrious Gaon Rabbi Zvi Hirsh Lehren. In 1830 he moved to EY and settled in Tzefas. In 1835, he married the granddaughter of Rabbi David Zvi Ha’gadol (the father-in-law of Rabbi Nosson of Breslov). Teshuvos Ha’Gaonim is his most well-known work.
