Stanley Casselman rose to art-world fame in an unusual way: he answered the critic Jerry Saltz’s call for a knock-off Gerhard Richter painting. But Casselman’s practice goes far beyond that. He was an established painter of geometric abstraction long before he started creating Richter-like works using a 10-foot squeegee. Since then, he has elaborated on this painting style, making it his own as he searches for logic through abstraction. “Each painting is its own visual story that transcends explanation through language,” Casselman has said. “The process and the result [are] emotion and energy put forth in its rawest and purest form.”
