Shaar Hashamayim Yeshiva
Shaar Hashamayim Yeshiva is an Ashkenazi yeshiva in Jerusalem dedicated to the study of the Kabbalistic teachings of the Arizal. It is famous for its student body of advanced Kabbalists — many of them Roshei Yeshiva and Torah scholars — as well as beginning and intermediate scholars who study both the revealed and concealed Torah.
The first Roshei Yeshiva of Shaar Hashamayim Yeshiva were the founders, Rabbi Chaim Yehuda Leib Auerbach and Rabbi Shimon Horowitz. Rabbi Auerbach chose to stay with the Yeshiva even after his father, the Admor of Chernowitz-Chmielnik, died and his Chassidim asked Rabbi Auerbach to take his father's place. He declined, leaving the position of Admor unfulfilled.
Following Rabbi Auerbach's death in 1954, his son, Rabbi Eliezer Auerbach, led the yeshiva for many years. After his death, another of Rabbi Auerbach's sons, Rabbi Refoel Dovid Auerbach, assumed leadership. Subsequent Roshei Yeshiva were Rabbi Aharon Slotkin (who died in 1973), Rabbi Yechiel Fishel Eisenbach (who served from 1973 until his death in 2008), and the current Roshei Yeshiva, Rabbi Yaakov Meir Shechter and Rabbi Gamliel Rabinowitz.
