"Ed Clark is an American Color Field painter whose style was shaped by the years he spent in Paris in the early 1950s. As an African-American who had been raised in the segregated South, he found Paris tolerant, and the atmosphere encouraging. While there, he developed a sophisticated abstract style that was markedly influenced by the tachist painter Nicolas de Stael. His early work is remembered for his "push-broom technique," which encouraged his full physical involvement in painting. He is also noted for the monumental scale of his work, and the fact that he is one of the first painters to have used shaped canvases
Two years later, Clark's family relocated north to Chicago. In 1943, at the age of 17, he left high school and enlisted in the air force during the height of World War II; he was stationed for two years in the South Pacific and returned to Chicago upon his release.
In addition to shifts in his color palette during the course of his career, Clark has also experimented with line and form. Much of his work during his early period maintained a strong horizontality that was congruent with the push of his broom. But in the 1980s he abandoned his three-unit Color Fields for tubular forms that are curved and multi-directional - a contrast to the static Color Fields of the 1950s. In the 1990s and the 2000s he began relying on vertical strokes combined with floating masses of color that intermingled with one another across the picture plane, resulting in monumental abstract compositions that reflect his entire career of experimentation with color, form, and line."
