Andy Warhol (/ˈwɔːrhɒl/; born Andrew Warhola; August 6, 1928 – February 22, 1987) was an American artist who was a leading figure in the visual art movement known as pop art. His works explore the relationship between artistic expression, celebrity culture, and advertising that flourished by the 1960s, and utilize a variety of media, including painting, silkscreening, photography, film, and sculpture. Some of his best known works include the silkscreen paintings Campbell's Soup Cans (1962) and Marilyn Diptych (1962), the experimental film Chelsea Girls (1966), and the multimedia events known as the Exploding Plastic Inevitable (1966-67).Born and raised in Pittsburgh, Warhol initially pursued a successful career as a commercial illustrator. After exhibiting his work in several galleries in the late 1950s, he began to receive recognition as an influential and controversial artist. His New York studio, The Factory, became a well-known gathering place that brought together distinguished intellectuals, drag queens, playwrights, Bohemian street people, Hollywood celebrities, and wealthy patrons. He managed and produced The Velvet Underground, a rock band which had a strong influence on the evolution of punk rock music. He founded Interview magazine and was the author of numerous books, including The Philosophy of Andy Warhol and Popism: The Warhol Sixties. He is also notable as a gay man who lived openly as such before the gay liberation movement, and he is credited with coining the widely used expression "15 minutes of fame".Warhol has been the subject of numerous retrospective exhibitions, books, and feature and documentary films. The Andy Warhol Museum in his native city of Pittsburgh, which holds an extensive permanent collection of art and archives, is the largest museum in the United States dedicated to a single artist. Many of his creations are very collectible and highly valuable. The highest price ever paid for a Warhol painting is US$105 million for a 1963 canvas titled "Silver Car Crash (Double Disaster)"; his works include some of the most expensive paintings ever sold. A 2009 article in The Economist described Warhol as the "bellwether of the art market".
