Yisroel Hopstein

Rabbi Yisroel Hopstein (Hebrew: ישראל הופשטיין;‎ 1737–1814), commonly known as the Maggid of Kozhnitz, (or Kozhnitser Maggid), was a towering figure in the third generation of the Hasidic movement, a noted Kabbalist, and the founder of the Kozhnitz Hasidic dynasty in Poland. His profound influence extended through the late 18th and early 19th centuries. He was a student of both the Magid/Dov Ber of Mezeritch and Elimelech of Lizhensk, and wrote many books on Chassidus and Kabbalah.

He is sometimes referred to as the "Avodat Yisrael" after the title of his most famous work, a commentary on the Torah.
