Joseph Duveen, 1st Baron Duveen (14 October 1869 – 25 May 1939), known as Sir Joseph Duveen, Baronet, between 1927 and 1933, was a British art dealer who was considered one of the most influential art dealers of all time. Life and career Joseph Duveen was British by birth, the eldest of thirteen children of Rosetta (Barnett) and Sir Joseph Joel Duveen, a Dutch-Jewish immigrant who had set up a prosperous import business in Hull. The Duveen brothers' firm became very successful and became involved in trading antiques. Duveen Senior died in 1908; Joseph took over the business, working in partnership with his late father's brother Henry J. Duveen. He had received a thorough and stimulating education at University College School. He moved the Duveen company into the risky, but lucrative, trade in paintings and quickly became one of the world's leading art dealers due to his good eye, sharpened by his reliance on Bernard Berenson, and skilled salesmanship. His success is famously attributed to his observation that "Europe has a great deal of art, and America has a great deal of money." He made his fortune by buying works of art from declining European aristocrats and selling them to the millionaires of the United States. Clients included Henry Clay Frick, William Randolph Hearst, Henry E. Huntington, Samuel H. Kress, Andrew Mellon, J. P. Morgan, John D. Rockefeller Sr., Edward T. Stotesbury, and a Canadian, Frank Porter Wood. The works that Duveen shipped across the Atlantic remain the core collections of many of the United States' most famous museums. Duveen played an important role in selling to self-made industrialists on the notion that buying art was also buying upper-class status. He greatly expanded the market, especially for Renaissance paintings with the help of Bernard Berenson, who certified some questionable attributions, but whose ability to put an artistic personality behind paintings helped market them to purchasers whose dim perception of art history was as a series of biographies of "masters." Duveen quickly became enormously wealthy and made many philanthropic donations. He donated paintings to British galleries and gave considerable sums to repair and expand several galleries and museums. He built the Duveen Gallery of the British Museum to house the Elgin Marbles and funded a major extension of the Tate Gallery. Honours For his philanthropy, he was knighted in 1919, made a Baronet of Millbank in the City of Westminster in
