Born in Baltimore, Maryland. Studied painting at the Mary-land Institute of Fine and Applied Arts in Baltimore. Left for New York City in 1936 where he was active in Siqueiros's work shop and other places. Returned to Baltimore in 1943, and became active in Washington in 1952, holding his first one-man show the following year. Inspired by Helen Frankenthaler's works, he used a technique whereby no brushes touched his canvas, rather he would drip thinned acrylic resin pigments into his raw canvas. The spread of color permeating the giant canvas created a painterly space, and he was acclaimed as one of the major Color Field Painters, continuing the work of the Abstract Expressionists. Died in Washington.
