Rabbi Yechiel Michel Epstein (1829–1908) was a distinguished halakhic authority and a prolific rabbinic scholar, widely known for his magnum opus, the Aruch HaShulchan. Born in Babruysk, Belarus, he was part of a prominent rabbinic family and demonstrated exceptional scholarship from a young age. He studied under some of the leading rabbinic figures of his time, including  Rabbi Naftali Zvi Yehuda Berlin.

In 1864, Rabbi Epstein was appointed the rabbi of Navahrudak (Novogrudok), a position he held for over 30 years. During his tenure, he became renowned not only for his erudition but also for his compassionate approach to the practical challenges faced by his community. His dual role as a rabbi and scholar informed his ability to harmonize halakhic rigor with sensitivity to human needs, which became a hallmark of his work.

Rabbi Epstein’s Aruch HaShulchan, published between 1884 and 1907, is a comprehensive halakhic digest following the order of the Shulchan Arukh. It systematically traces Jewish laws back to their biblical and Talmudic roots while incorporating the rulings of later authorities. Unlike other works that focus on specific commentaries, Rabbi Epstein’s Aruch HaShulchan provides a unified and practical presentation of Jewish law, earning it widespread respect and use among both scholars and laypeople.

In addition to the Aruch HaShulchan, Rabbi Epstein wrote Aruch HaShulchan He’Atid, which addresses laws related to the Temple and sacrificial offerings, reflecting his deep engagement with all areas of Jewish law. Rabbi Epstein’s contributions remain a cornerstone of halakhic study and practice. His legacy endures not only in the Aruch HaShulchan but also in his ability to make Jewish law accessible and relevant to diverse audiences, bridging the gap between scholarship and daily observance.
