Born in Jerusalem in 1910 during the Ottoman Empire, he studied at leading yeshivot including Etz Chaim Yeshiva and under rabbis linked to the traditions of Vilna Gaon, Shulchan Aruch, and the Lithuanian yeshiva movement such as Rabbi Chaim Ozer Grodzinski and Rabbi Avraham Yeshaya Karelitz. He married into families connected to Rabbi Yosef Chaim Sonnenfeld and the Old Yishuv, and his household interacted with activists from Zionist Organization, Hapoel Hamizrachi, and communal leaders of Jerusalem like Chief Rabbi Abraham Isaac Kook.

He engaged in halachic debate with authorities like Rabbi Moshe Feinstein over industrial and commercial dilemmas, consulted with Rabbi Shlomo Goren on military chaplaincy issues, and corresponded with Rabbi Elazar Shach on communal policy and yeshiva governance. His positions on technology in halacha influenced rulings in rabbinic courts such as the Beit Din of Jerusalem, and informed policy at institutions like Shaare Zedek Medical Center, Hadassah Medical Center, and Rabin Medical Center.
