European Jews on a fairly considerable scale drifted into the visual arts world as collectors and dealers in the 19th century and became, against all odds, arbiters of taste. Once regarded as outsiders on the margins of high culture, they were suddenly thrust into positions of prestige and influence. Charles Dellheim, a professor of history at Boston University, charts their entry into this field in his masterful and magisterial book, Belonging and Betrayal: How Jews Made The Art World Modern, published by Brandeis University Press….Dellheim has written a highly readable, substantive and engaging account of the entry of Jews into art. It may well be the definitive work on this topic.
