1898-1919A group of New York and Boston Impressionists who had visited Gloucester formed “The Ten American Painters,” also known as “The Ten.”Arts and Culture, Art

“The Ten” rebelled against a conservative art establishment and seceded from the conservative Society of American Artists. This group was formed in 1877 in a challenge to the more conservative National Academy of Design. The “Society,” now itself conservative, rejected a painting by Twachtman as being too radical. Several members, of “The Ten,” including Joseph DeCamp, Willard Metcalf, Childe Hassam, Edmund Tarbell, and of course, John Twachtman, visited and painted Gloucester in the 1890s, and are considered to have done some of their finest works there. When the group disbanded in 1919, Impressionism was part of the American cultural establishment.
