Isaac Klein

About the Author

Isaac Klein (1905-1979) was a prominent American rabbi, scholar, and author whose work bridged traditional Jewish observance with modern life. Born in Lithuania and immigrating to the United States as a child, he served as a congregational rabbi in Cleveland, Ohio, for over four decades, while also teaching at Hebrew Union College-Jewish Institute of Religion. Klein's writings reflect his deep commitment to halakhah, the Jewish legal tradition, making complex rituals accessible to contemporary audiences. His seminal book, A Guide to Jewish Religious Practice, remains a cornerstone for Reform Judaism, offering practical guidance on holidays, lifecycle events, and daily observances. Through his scholarship and pastoral leadership, Klein influenced generations of Jews seeking to integrate faith into everyday existence.
