The early 20th century was marked by the exploration of different techniques and ways of artistic expressiveness. Many American artists like Wilhelmina Weber, Man Ray, Patrick Henry Bruce, Gerald Murphy and others went to Europe, notably Paris, to make art. The formation of various artistic assemblies led to the multiplicity of meaning in the visual arts. The Ashcan School gathered around realism (Robert Henri or George Luks); the Stieglitz circle glorified abstract visions of New York City (Max Weber, Abraham Walkowitz); color painters evolved in direction of the colorful, abstract "synchromies" (Stanton Macdonald-Wright and Morgan Russell), whereas precisionism visualized the industrialized landscape of America in the form of sharp and dynamic geometrization (Joseph Stella, Charles Sheeler, Morton Livingston Schamberg, Charles Rosen, and Charles Demuth). Eventually artists like Charles Burchfield, Marsden Hartley, Stuart Davis, Arthur Dove, Georgia O'Keeffe who was thought of as the mother of American Modernism, John Marin, Arthur Beecher Carles, Alfred Henry Maurer, Andrew Dasburg, James Daugherty, John Covert, Henrietta Shore, William Zorach, Marguerite Thompson (Zorach), Manierre Dawson, Arnold Friedman and Oscar Bluemner ushered in the era of Modernism to the New York School.
