Pat Steir (American, b.1940) is an influential painter, best known for her Waterfall series of splashed, dripping paint on canvas. She first began using this method in the late 1980s, and has continued the series ever since. Her work was influenced by Color Field painting, Abstract Expressionism, and Taoist philosophy, and over the course of her career, Steir befriended and learned from many influential Conceptual and Minimalist artists of the day, including Sol Lewitt, Agnes Martin, and Lawrence Weiner.
