Robert Irwin, Light and Space pioneer, dies at 95

Robert Irwin, a defining member of California's Light and Space movement, has died. Born in 1928, he began as a painter but shifted to installation art by the late 1960s, abandoning his studio in 1969 to work on an architectural scale. He created site-specific works using fluorescent lights, tinted gels, paint, glass, and windows, responding to environmental light conditions. Permanent installations exist at The Chinati Foundation in Marfa, Texas, and Dia:Beacon in Upstate New York. His work fused science, philosophy, and artistic experimentation. A two-person show with Mary Corse, 'Parallax,' is currently at Pace Gallery in London. A documentary, 'A Desert of Pure Feeling,' is streaming on Amazon and Apple TV.
