Robert Irwin was an American artist who left a lasting mark on contemporary art for nearly 70 years. He began his career with painting in the late 1950s, but it was in the following decade that he started experimenting with light, space and materials. Irwin is renowned for installations that offer a completely different way of experiencing art. As a pioneer of the "Light and Space" movement in California, he challenged traditional boundaries by focusing on light, space and sensory experience.
