For legendary Talmud scholar and prolific author Rabbi Adin Even-Israel Steinsaltz, the Lubavitcher Rebbe embodied a lifelong mission to better the world. Far surpassing the role of teacher, Rabbi Menachem Mendel Schneerson was at once a scientific mind and faithful believer; educational innovator and social activist; spiritual guide and master network builder. My Rebbe is Rabbi Steinsaltz's long-awaited personal testament to the man whose passion and vision transformed Chabad-Lubavitch from a tiny group of Chassidim into an educational and spiritual movement that spans the globe. With the admiration of a close disciple, the astute observation of a scholar and the spiritual depth of a mystic, Steinsaltz crafts an intimate portrait of a revolutionary religious leader whose dedication to intellectual, religious, and spiritual principles impacted generations of followers.
