Andy Warhol studied at the Carnegie Institute of Technology from 1945 to 1949, before moving to New York to work in advertising. He began exhibiting his work in the 1950s and in 1952 had his first solo exhibition at the Hugo Gallery in New York. Numerous major retrospectives of his work have taken place worldwide. Important public collections include The Metropolitan Museum of Art, New York; Museum of Modern Art (MoMA), New York; Guggenheim Museum, New York; and Tate, London. The Andy Warhol Foundation for the Visual Arts was formed in 1987 and two museums, in Slovakia and Pittsburgh, are dedicated to his work.
