Rabbi Menaḥem Mendel of Kotzk (1787–1859,) originally surnamed Morgenstern and known as the Kotzker Rebbe, was a Hasidic leader renowned for his uncompromising pursuit of truth and authenticity.
Born Menachem Mendel Morgensztern in Goraj, Poland, he grew up in a non-Hasidic family. Drawn to Hasidism, he first entered the court of Ya’akov Yitsḥak Horowitz, the Seer of Lublin. He later found a mentor in Ya’akov Yitsḥak Rabinowitz of Pshiskhe (Przysucha,) and after Rabinowitz’s death became a disciple of Simḥah Bunem of Pshiskhe. Gifted in Talmud and Kabbalah, Mendel attracted many followers with his sharp intellect and fearless critiques of superficial piety. His teachings emphasized honesty, inner integrity, and the rejection of empty ritual.
From 1839, he lived in seclusion for two decades, yet his influence endured through disciples such as Rabbi Yitzchak Meir Alter, founder of the Ger dynasty, and Rabbi Mordechai Yosef Leiner of Izbica. Though he burned his manuscripts before his death, collections of his sayings—such as Emet VeEmunah—preserve his legacy. Menachem Mendel of Kotzk remains a towering figure in Hasidism, remembered for his incisive wit and demand for spiritual authenticity.
Works about Rabbi Menachem Mendel include Joseph Fox’s Rabbi Menachem Mendel of Kotzk: A Biographical Study of the Chasidic Master (1988) and Chaim Feinberg’s Leaping Souls: Rabbi Menachem Mendel and the Spirit of Kotzk (1994.)
