1930- . US painter and printmaker who rejected the abstract in favour of such simple subjects as flags, maps, and numbers. He uses pigments mixed with wax (encaustic) to create a rich surface with unexpected delicacies of colour. He has also created collages and lithographs. Born in Augusta, Georgia, he moved to New York City in 1952. In the 1960s his works became more abstract before veering toward abstract expressionism in the mid-1970s. He was influenced by Marcel Duchamp.
