Impressionism begins in America around 1875 and continues through the first quarter of the 20th century. American artists modified in a clearly American manner the soft brush strokes of the French. While the list of artists that painted in an impressionist manner is lengthy, it is the works of John Singer Sargent, Childe Hassam, Mary Cassatt, Theodore Robinson, James McNeill Whistler, J. Alden Weir and J.J. Enneking that are considered the leaders of the American movement.
