Baruch ben Jehiel of Medzibezh (1757–1810), hasidic zaddik; grandson of R. Israel b. Eliezer the Baal Shem Tov, the founder of modern Hasidism. R. Baruch, who studied under R. Phinehas Shapira of Korets, officiated from 1780 as rabbi in Tulchin, but encountered opposition and returned to Medzibezh in 1788. He attributed great importance to his descent and regarded himself as the heir to the Ba'al Shem Tov's leadership. He held that the zaddik could save and lead the whole world; the duty of the common man was only "to destroy the evil impulses and abandon his desires." Regarding himself as the leader of Hasidism by hereditary right, he held "court" in Medzibezh in a highly autocratic and luxurious fashion, though preaching asceticism to others. He kept a "court jester," Hershele Ostropoler. His behavior aroused opposition from other hasidic leaders. In 1808 he met Shneur Zalman of Lyady in an effort to settle their differences. Baruch attached mystical importance to the custom practiced by Hasidim of giving presents to the rabbis (pidyonot). He encouraged Hasidim to immigrate to Erez Israel. He took part in the assembly of hasidic rabbis at Berdichev (1802–03) that discussed the government's prohibition of Jewish settlement in the villages among other matters. His writings include Amarot Tehorot (1865; first published in his brother's (R. Moses Hayyim Ephraim) Degel Mahaneh Ephraim, Zhitomir, 1850) and Buzina di-Nehora (1880).
