Joseph Saul Nathansohn

Joseph Saul Nathansohn (1808–1875) (Hebrew: יוסף שאול בן אריה הלוי) was a Polish rabbi and posek, and a leading rabbinical authority of his day.

Biography

Rabbi Nathansohn was born at Berezhany (Berzan), Galicia (today's western Ukraine); he was the son of Aryeh Lebush Nathanson, rabbi at Berzan and author of "Bet El." He studied Talmud at Lviv (Lemberg) together with his brother-in-law Mordecai Zeeb Ettinger. In the 1830s in Lemberg—then under the rule of the Austrian Empire—he founded an informal study-group under his tutelage; this “yeshiva” attracted some of the most brilliant students in Galicia. In 1857 Nathanson was elected rabbi of Lemberg, where he officiated for eighteen years. He was a widely recognized rabbinical authority, and was asked to rule on various contemporary issues; his rulings are still widely cited (for instance he was one of the first to permit the use of machinery in baking Matzah, which created a widespread halachic controversy^[1]). Nathanson was very wealthy, and was known for his activity as a philanthropist. He died at Lemberg March 4, 1875.
