Robert Irwin (b. 1928) is a pioneering figure of the Los Angeles-based Light and Space movement of the 1960s. Beginning his career as a painter, Irwin later began exploring perception and light with his acrylic columns and discs.
n 1969, he gave up his studio and began what he termed a conditional practice, working with the effects of light through subtle interventions in space and architecture. Irwin employs a wide range of media—including fluorescent lights, fabric scrims, colored and tinted gels, paint, wire, acrylic, and glass—in the creation of site-conditioned works that respond to the context of their specific environments.
