1745 - 1813 (24 Tevet 5573) SHNEUR ZALMAN (Lyady/Liadi, Russia)
Founded an intellectualized form of Hasidism called Habad (Chabad). The name is derived from the initials Chachma (wisdom), Binah (understanding) and Daat (knowledge). His intention was to bridge the gap between the Mitnagdim and the Hasidim, combining intellectualism and mysticism. His Lekutei Amarim (Collected Sayings) became known as the Tanya and is one of the important study texts of the Habad (Chabad) Hasidim.
