The Realism movement was active from 1830 to 1870 and is also known as the Realist School. The movement discarded the previous traditional styles and formulas of Neoclassicism and Romanticism. The Realist artist portrays subjects in the most straightforward manner possible without idealizing them, and without following previous art theories. The earliest works from the Realist movement arose in the 18th century as a reaction against Neoclassicism and Romanticism. The works of Copley and Goya are an example of the early influences on Realism. The period was in full swing by the mid 19th century when artists became anxious with the influence of the Academies. The Ashcan School, the Contemporary Realist, and the American Scene Painters are all movements that are based on the Realist tradition. Famous artists of the Realist movement include Gustave Courbet, Honore Daumier, John Singer Sargeant, J A Macneil Whistler, Jean-Francois Millet, and Jean-Baptiste-Camille Corot.
