Unknown Artists --- American Impressionism:
A style that evolved from French Impressionism but placed more emphasis on form or recognizable subjects. Chief exponents were William Merritt Chase, who founded one of the first outdoor painting schools in 1878 in New York, and his student, Charles Hawthorne, who founded the Cape Cod School of Art in 1899. They espoused painting 'en plein air' (finishing the work on location) and depicting the changing effects of light with masses of color while modeling and defining the forms with distinct color variations.
