An early-20th-century movement in American abstract art with a style characterized by clean lines, simple forms, large areas of flat color, and smooth finish. Often the subjects were vernacular architecture or industrial buildings, usually devoid of human presence. Among the artists associated with Precisionism are Charles Sheeler, Charles Demuth, George Ault, Elsie Driggs, Louis Lozowick, Ralston Crawford and Niles Spencer. Web resource here.
