Robert Irwin is one of the most significant and prolific American artists of the postwar generation. Frequently associated with Light and Space Art, Irwin got his start in the 1950s as a Los Angeles–based abstract painter. He quickly began to question the conventions of painting—including its framing devices. Irwin then "broke the frame," turning to the ambient environment itself as his medium. He began modestly in the early 1970s with a series of subtle interventions in art galleries and museums. In 1975, however, Irwin made the crucial step outside these spaces, by engaging directly with the outdoor world. Site-determined art gets its start here, with Irwin's move beyond the traditional spaces of the art world and into the lived environment. Robert Irwin: Site Determined is the first exhibition to explore four decades of the artist's outdoor environmental projects through his drawings and architectural models.

For more than six decades, Robert Irwin has explored perception as the fundamental issue of art. Irwin, who began his career as a painter in the 1950s and became a pioneer of the Los Angeles-based “Light and Space” movement in the 1960s, has, through a continual breaking down of the frame, come to regard the role of art as “conditional”—working within and responding to the specific surrounding world of experience. Irwin has conceived over fifty-five site-conditional projects, ranging from Window Wall for California State University, Long Beach (1975), to Filigreed Line, at Wellesley College, Massachusetts (1980), 9 Spaces, 9 Trees for the Public Safety Building Plaza, Seattle (1983), Wave Hill Green, at Wave Hill, Bronx, New York (1986–87), the Central Gardens for the Getty Center in Los Angeles (1992–98), the architectural and grounds design of Dia:Beacon, New York (1999–2003), and Primal Palm Garden at the Los Angeles County Museum of Art (2007–10). Irwin’s most recent large-scale permanent installation, the first free-standing structure devoted exclusively to his work, at the Chinati Foundation in Marfa, Texas (2001–16), draws viewers’ attention to the subtleties of light, space, and surrounding landscape. Irwin was awarded a Guggenheim Foundation Fellowship in 1976, received the John D. and Catherine T. MacArthur “Genius” Award in 1984, and was elected as an Academician at the National Academy in 2012. His work has been featured in over seventy-five solo exhibitions, and is included in the collections of major public institutions worldwide. Pace Gallery has represented Irwin since 1966.
