Kalonymus Kalman Shapira

Also known as The Piaseczner Rebbe

1889 CE–1943 CE · Modern · Grodzisk Mazowiecki

Rabbi Kalonymus Kalman Shapira (1889–1943) was a Hasidic master and founder of the Piaseczno dynasty in Poland. Heir to the Hasidic courts of Grodzisk and Kozhnitz — a descendant of the Maggid of Kozhnitz and Rabbi Elimelech of Lizhensk — he became known for his innovative approach to spiritual psychology and introspection, emphasizing the inner emotional and psychological dimensions of religious practice. He established a yeshiva in Piaseczno (near Warsaw) that attracted devoted followers seeking a more emotionally engaged and psychologically sophisticated Hasidic path. During the Nazi occupation of Poland, he continued to lead and inspire his community even in the Warsaw Ghetto, where he taught and counseled others despite unimaginable suffering. He was murdered by the Nazis at the Trawniki camp in November 1943. His writings — especially Chovat HaTalmidim and the Aish Kodesh, the sermons he delivered in the Warsaw Ghetto — profoundly influenced modern Jewish spirituality.
