American philanthropist (b. June 11, 1907, Pittsburgh, Pa.-d. Feb. 2, 1999, Upperville, Va.), was heir to an enormous fortune amassed by his father, financier and industrialist Andrew W. Mellon, but chose not to centre his career in the business world. Instead, he sought to contribute to the cultural life of the country and eventually gave about a billion dollars to fund and house art collections, protect and enhance the environment, and support education and the musical and literary arts. Following studies at Yale University (A.B., 1929) and Clare College, Cambridge (A.B., 1931), Mellon began working at the Mellon Bank in Pittsburgh. He did not feel suited to that life, however, and by the end of 1936 had told his father that what he wanted to do was collect art and present it to the public. Mellon's father, who had already donated money and paintings for the National Gallery of Art, agreed to his son's plan. Construction of the gallery began in 1937, and Mellon presented the gallery, with the Andrew Mellon Collection, to the country in 1941. Mellon, who in his youth had developed a passion for horses, joined the cavalry and taught horsemanship for two years after the U.S. entered World War II. He was then sent to England and worked his way up to the rank of major in the Office of Strategic Services. A main focus of his postwar years was the expansion of the National Gallery. He chose I.M. Pei as architect, and in 1978 the impressive trapezoid-shaped East Building was completed. Mellon served more than 40 years on the National Gallery's board and donated 913 works of art. Another of his chief accomplishments was the building of the Louis Kahn-designed Yale Center for British Art, which opened in 1977 to house the holdings that his years in England had inspired him to collect. Mellon's concern for the environment led him to aid such areas as the Cape Hatteras (North Carolina) National Seashore, Lafayette Park in Washington, D.C., and Sky Meadows State Park in Virginia, and his love of literature led him to establish the Bollingen Foundation, which published a number of important literary works and created the Bollingen Prize, one of the major American awards for poetry. Additional beneficiaries of Mellon's generosity included the Pittsburgh Symphony Orchestra, the Royal Veterinary College at the University of London, and London's Tate Gallery. Mellon also bred horses and counted Belmont Stakes winners Quadrangle (1964) and Arts and Letters (1969) and Kentucky Derby champion Sea Hero (1993) among his successes. In 1998 he was rated 124th richest American by Forbes magazine
