art, both in his native Germany and later in the U.S. Hofmann, who came to the United States from Germany in the early 1930s, brought with him the legacy of Modernism. Hofmann was a young artist working in Paris who painted there before World War I. Hofmann worked in Paris with Robert Delaunay, and he knew firsthand the innovative work of both Pablo Picasso and Henri Matisse. Matisse's work had an enormous influence on him, and on his understanding of the expressive language of color and the potentiality of abstraction. Hofmann was one of the first theorists of color field painting, and his theories were influential to artists and to critics, particularly to Clement Greenberg, as well as to others during the 1930s and 1940s. In 1953 Morris Louis and Kenneth Noland were both profoundly influenced by Frankenthaler's stain paintings after visiting her studio in New York City. Returning to Washington, DC., they began to produce the major works that created the color field movement in the late 1950s. In 1972 then Metropolitan Museum of Art curator Henry Geldzahler said: Clement Greenberg included the work of both Morris Louis and Kenneth Noland in a show that he did at the Kootz Gallery in the early 1950s. Clem was the first to see their potential. He invited them up to New York in 1953, I think it was, to Helen's studio to see a painting that she had just done called Mountains and Sea, a very, very beautiful painting, which was in a sense, out of Pollock and out of Gorky. It also was one of the first stain pictures, one of the first large field pictures in which the stain technique was used, perhaps the first one. Louis and Noland saw the picture unrolled on the floor of her studio and went back to Washington, DC., and worked together for a while, working at the implications of this kind of painting.Carmean, E.

Abrams in conjunction with The Museum of Modern Art, Fort Worth, Morris Louis's painting Where 1960, was a major innovation that moved abstract expressionist painting forward in a new direction toward color field and minimalism. Among Louis's major works are his various series of color field paintings. Some of his best known series are the Unfurleds, the Veils, the Florals and the Stripes or Pillars. From
