Yisroel Hopstein

Yisroel Hopstein (1737–1814), also known as the Maggid of Kozhnitz, was the founder of Kozhnitz Hasidism, and a noted hasidic leader in Poland during the late 18th and early 19th century. 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" for his works.

Biography
Hopstein was born in Opatów, to his father, Shabbetai, who was at an advanced age, after having received a blessing from the Baal Shem Tov. The father was a bookbinder; his mother's name was Perl.

As a young child he was recognized as an illui (prodigy). He studied under the tutelage of Rabbi Shmelke of Nikolsburg, who eventually convinced Hopstein to learn with Dov Ber, the Maggid of Mezritch. After the passing of Dov Ber, he went to learn with Elimelech of Lizhensk.

Hopstein lived for years in Kozhnitz (Kozienice), was founder of the Kozhnitz Hasidic dynasty and died the 14th of Tishrei (September 28, 1814).
