An early 20th-century abstract movement in American art with a style noted for clean-cut, severe-seeming lines, simple forms, large areas of flat color, smooth finish and the conveying of a general sense of good order and precision. Often the subjects were architectural or industrial and usually devoid of human reference. Precisionist Painters, sometimes called The Immaculates, were never organized officially but simply shared a style and certain convictions about art. Among them are Charles Sheeler, Charles Demuth, Georges Ault, Niles Spencer and Ralston Crawford. Sources: "Phaidon Dictionary of 20th Century Art"; AskART database
