The Admo"r Rabbi Yehudah Aryeh Leib Alter of Gur [1847-1905] was the second Admo"r in the Gur dynasty, and one of the most prominent leaders of Polish Jewry towards the end of the 19th century. Under his leadership, Gur Chassidism became the central Chassidic sect in Poland. This book, by which he is known as the "Ba'al HaSefat Emet," was greatly admired for its depth and genius. It became known for its great influence, even beyond Chassidic courts, extending into Mitnaged circles.
