born Nov. 30, 1904, Grandin, N.D., U.S.
died June 23, 1980, Baltimore, Md.
U.S. painter.
He studied at Spokane University and Washington State College. After experimenting with several styles, he became involved in Abstract Expressionism and was a pioneer of very large, monochromatic painting. His work is often characterized within the "colour-field" subset of Abstract Expressionism. He used thickly applied, opaque paint (impasto) in expressively modulated, jagged forms to portray raw, aggressive power.
