Book excerpt: Kaplan, who died in 1983 at the age of 102, arrived in America as a boy, and, as he grew, sought to find ways of making Judaism compatible with the American experience and the modern temper. He founded the Jewish Center and the Society for the Advancement of Judaism, establishing the prototypes for the modern expanded synagogue. This biography reappraises the significance of his contributions and offers an intimate look at the man and his thinking. Annotation copyright by Book News, Inc., Portland, OR
