Shimon Gershon Rosenberg

Rabbi Shimon Gershon Rosenberg, known also as Rav Shagar (an acronym), was a Torah scholar and a religious postmodern thinker in the 20th and 21st centuries. His teachings draw upon Chasidic teachings, the work of early Religious Zionist thinkers — particularly that of Rav Kook — and contemporary philosophy, with an eye toward deepening personal religious experience. In 1996, together with Rabbi Yair Dreifuss, he established Yeshivat Siach Yitzchak, where he served as head of the yeshiva until his death in 2007.
