Kalonymus Kalman Epstein of Kraków

Kalonymus Kalman ha-Levi Epstein (1753-1823) was the pioneering figure who, against significant opposition, introduced Hasidism to the Jews of Kraków, Poland. The book comprising his homilies, Ma’or va-shemesh, first printed in 1842, became one of the most popular of the Hasidic homily-texts.
