Divided into three sections, this work explains how the concepts and practices of traditional European Judaism were adapted to North American culture beginning in the late nineteenth century. Part I focuses on the ideas and activities of Cyrus Adler (1863-1940), one of the most prominent leaders of the traditionalist Jewish community in the United States in his era. Part II deals with the beginnings of Hasidic Judaism in North America prior to the Second World War. It also includes several studies investigating the shaping of the worldview of Orthodox Judaism in contemporary North America. Part III examines the issue of contemporary American Jewish attitudes toward evolution and intelligent design.
