Rabbi Shimon Horowitz (1870-1947) was the eldest of the kabbalists of Jerusalem. He was a frequenter of Rabbi Kook's home.
He was born in Lida (thus his name 'Lidar') on the 12th of Sivan 1870. He studied in a yeshiva in Vilnius, where he secretly studied kabbala.
He was one of the founders of the Sha'ar Ha'Shamayim kabbalist yeshiva and the author of several kabbala books. He studied Torah at the Etz Chaim Yeshiva, headed then by Rabbi Shmuel Salant, and Kabbala at the Beit El yeshiva, since in those days, there was no yeshiva for Ashkenazic Kabbalists in Jerusalem. He corresponded with the most prominent kabbalists in Israel and abroad.
He was also preoccupied with finding the Ten Lost Tribes. His book on the subject "Kol Mevaser" was approbated by rabbi Avraham Yitzchak Ha'Cohen Kook.
During the Holocaust, the kabbalists of Jerusalem held a special prayer to stop the Nazis from conquering the Land of Israel. They were headed by Rabbi Shimon Horowitz. One of its participants, Rabbi Moshe Ya'ir Weinstock, described the special prayer: "We gathered a kind of Beit Din and excommunicated Hitler and Goebbels and their assistants. Indeed, Rommel was immediately defeated and escaped Egypt".
