Anyone who has admired Gainsborough's "Blue Boy" of the Huntington Collection in California, or Rembrandt's Aristotle Contemplating the Bust of Homer at the Metropolitan Museum of Art in New York owes much of his or her pleasure to the art dealer Joseph Duveen (1869-1939). Regarded as the most influential - or, in some circles, notorious - dealer of the twentieth century, Duveen established himself selling the European masterpieces of Titian, Botticelli, Giotto, and Vermeer to newly and lavishly wealthy American businessmen - J. P. Morgan, John D. Rockefeller, and Andrew Mellon, to name just a few. It is no exaggeration to say that Duveen was the driving force behind every important private art collection in the United States. The first major biography of Duveen in more than fifty years and the first to make use of his enormous archive - only recently opened to the public - Meryle Secrest's "Duveen" traces the rapid ascent of the tirelessly enterprising dealer, from his humble beginnings running his father's business to knighthood and eventually a peerage. The eldest of eight sons of Jewish-Dutch immigrants, Duveen inherited an uncanny ability to spot a hidden treasure from his father, proprietor of a prosperous antiques business. After his father's death, Duveen moved the company into the riskier but lucrative market of paintings and quickly became one of the world's leading art dealers. The key to Duveen's success was his simple observation that while Europe had the art, America had the money; Duveen made his fortune by buying art from declining European aristocrats and selling it to the "squillionaires" in the United States.
