Shmuel Bornsztain of Sochatchov

Rabbi Shmuel Bornsztain (1855–1926), known as the Shem MiShmuel after his collected teachings, was a Hasidic master and rosh yeshiva of Sochatchov in central Poland. He was the son of Rabbi Avraham Borenstein, founder of the Sochatchov dynasty, and became one of the most influential leaders of Polish Hasidic Jewry in the early twentieth century. He was renowned for his profound and systematic approach to Hasidic thought, synthesizing kabbalistic concepts with ethical teaching. He led the famed Sochatchov yeshiva, which produced numerous distinguished disciples. His collected discourses, published posthumously as Shem MiShmuel, remain influential in Hasidic and yeshiva circles, and he is remembered as a bridge between traditional Hasidic piety and modern yeshiva learning.
