R. Klonimus Kalman b. Aaron ha-Levi Epstein of Cracow (d. 1823), hasidic zaddik. A disciple of R. Elimelech of Lyzhansk and R. Jacob lsaac ha-Hozeh ("the Seer") of Lublin, he became noted for the ecstatic mode of prayer he adopted. In 1785 he organized groups of Hasidim in Cracow, and arranged minyanim where they prayed with devekut ("devotion") employing pronounced bodily movements. They were strongly opposed by the Cracow community, this opposition resulting in excommunications issued by R. Isaac Ha-Levi of Cracow and his bet din in 1786 and 1787. R. Epstein, however, withstood his opponents and actively propagated Hasidism throughout western Galicia.
