Larry Gagosian opened his first gallery in Los Angeles in 1980, specializing in modern and contemporary art. Five years later, he expanded his business to New York, inaugurating his first gallery in Chelsea with a Pop Art exhibition, with works from the Emily and Burton Tremaine collection. From 1989 to 1996, together with the well-known art dealer Leo Castelli, he had a gallery at 65 Thompson Street in Soho, where Ellsworth Kelly, Roy Lichtenstein, Bruce Nauman and other important post-war artists exhibited. In thirty years Gagosian has evolved into a global network with sixteen exhibition spaces in New York, Los Angeles, San Francisco, London, Paris, Rome, Athens, Geneva and Hong Kong, designed by world-renowned architects, including Caruso St John, Richard Gluckman, Richard Meier, Jean Nouvel, Selldorf Architects and wHY Architecture. The Rome office was opened in 2007.
