R. Yonatan Eybeschutz

Rabbi Jonathan Eybeschutz (c. 1690–1764) was a prominent Ashkenazi halakhic authority and Kabbalist who lived during the early modern period. Born in Kraków, he served as rabbi in several communities including Prague, Metz, and Amsterdam before settling in Altona-Hamburg-Wandsbeck, where he became one of the most influential rabbinic figures of Northern European Jewry. He was renowned for his vast erudition in Talmud, halakha, and Kabbalah, and authored numerous works including the Kereti u-Pleti and novellae on the Shulhan Arukh. Eybeschutz was involved in the bitter controversy surrounding Sabbatean theology, accused by some contemporaries of harboring Sabbatean sympathies—claims he vigorously denied. He remained a towering intellectual authority until his death, deeply respected for his learning and piety.
