Andy Warhol was born in 1928 in Pittsburgh to immigrant parents from Czechoslovakia. He studied pictorial design at the city's Carnegie Institute of Technology, then moved to New York City upon graduation. Relinquishing a successful and acclaimed career as a commercial illustrator in New York in the 1950s, he began exhibiting paintings with silkscreened Pop imagery in 1962. In 1963 he began to produce films and other projects, including Interview magazine, which was begun in 1969. Retrospectives of his work have been organized by the Pasadena Art Museum (1970), the Museum of Modern Art, New York (1989), and the Neue Nationalgalerie, Berlin (2002). Shadows (1979) was first exhibited at Heiner Friedrich's gallery at 393 West Broadway, New York City, in January 1979, and most recently at Dia in 1998–99. Dia's other exhibitions of Warhol's work include "Andy Warhol: Disaster Paintings, 1963" (1986), "Andy Warhol: Hand-Painted Images, 1960–62" (1987), and "Andy Warhol: Skulls" (1987–88). Warhol died in 1987. In 1994, Dia collaborated with the Carnegie Institute and the Andy Warhol Foundation for the Visual Arts to open the Andy Warhol Museum in Pittsburgh.
