Agnew's, as it is commonly called, has long held a prominent position in the Bond Street trade in Old Master pictures. The founder's sons, Sir William Agnew, 1st Baronet (1825–1910) and Thomas Agnew (1827–1883), were pivotal in the firm's rise in London, where Agnew's first established itself in 1860. Broadly speaking , Sir William's line produced the in-house connoisseurs (most notably C. Morland Agnew [1855–1931]), while Thomas's son, W. Lockett Agnew (1858–1918), inherited his father's commercial flair. It was William Agnew who shifted the gallery trade to Old Masters. As "The Times" noted in Sir William's obituary, "in 1877 the firm had built rooms in 39 Old Bond Street (later called 43 Old Bond Street), and when the succession of Old Master exhibitions, the example of Sir Richard Wallace and the Rothschilds, and the revived passion for eighteenth-century architecture and furniture had turned the taste of  the new rich men back to the older art, William Agnew was ready to find the pictures." Agnew's acted as principal agent and advisor to Edward Cecil Guinness, 1st Earl of Iveagh (1847–1927). The firm also held a significant part in the collecting activities of Alfred Beit (1853–1906), John G. Johnson (1841–1917), Alfred de Rothschild (1842–1918), Ferdinand de Rothschild (1839–1898), Henry Clay Frick, and George Salting (1835–1909). King George V (1865–1936) visited Agnew's Bond Street galleries on numerous occasions. Additionally, Agnew's often served as agent for the National Gallery in the salerooms. More recently, important clients include  Paul Mellon (1907–1999), Norton Simon (1907–1993), and the Samuel Henry Kress Foundation. In the late 19th and early 20th century, the firm was well regarded not only by the era's leading collectors, but also by fellow dealers. Consequently, in Bond Street, Agnew's enjoyed friendly relations with Knoedler, Arthur Joseph Sulley (1853–1930), the Wertheimer brothers, and in Paris, Charles Sedelmeyer (1837–1925). During the remainder of the 20th century and up to today, Agnew's has placed many masterpieces in major museums in Europe, America, and in emerging global markets. The contributions to the collections of the Metropolitan Museum of  Art, the National Gallery of Art, Washington, DC, and the National Gallery, London, are noteworthy. The firm has handled major pictures by, amongst others, Caravaggio, John Constable, Van Dyck, El Greco, Guercino, Frans Hals, Poussin, Rembrandt, Rubens, Vermeer, Titian, Pontormo, J.M.W. Turner, Joseph Wright of Derby, and Velázquez, including the latter's "Rokeby Venus" in the National Gallery, London. Agnew's also exhibited and sold works of Impressionist and Modern artists such as Paul Cézanne, Camille Pissarro, Paul Gauguin, Claude Monet, Pierre-Auguste Renoir, Edgar Degas, and Pablo Picasso. In recent years, the gallery has increasingly promoted the establishment of  lesser-known artists of the early twentieth century, namely the German-Swedish painter and portraitist Lotte Laserstein. In 2008, the purpose-built gallery in Old Bond Street (1877), designed by Salomons & Wornum, was sold by Agnew's to Etro, the Italian fashion house. In 2013, after nearly two centuries of family ownership, Agnew's closed. The name was subsequently purchased privately and the new gallery relocated its gallery premises to 6 St James's Place, London, under the directorship of art historian Lord Anthony Crichton-Stuart. The Agnew family will continue as consulting participants in the firm's operation. The  archive was given to the National Gallery.
