Belonging and Betrayal is a brilliantly etched portrayal of the family firms that maneuvered, battled, adapted, persevered, and prospered over decades and centuries. What underlies all of Charles Dellheim’s painstaking research lies a loving devotion to the subject matter. That means, above all, that his discussion of cultural and aesthetic matters rests on a bedrock of economic and business history. The element so often missing from studies of Jewish participation in Western culture here properly takes center stage. In this masterwork, Dellheim shows how to understand the business of culture.
