Twachtman is the most interesting of the American painters to be influenced by French Impressionism. It was he who conceived the idea in 1898 of founding a group, 'Ten American Painters', as official representatives of Impressionism in the United States. The group consisted of Frank Benson, Joseph de Camp, Thomas Dewing, Childe Hassam, Willard Metcalfe, Robert Reid, Edward E. Simmsons, Edmund Tarbell and J.Alden Weir, as well as Twachtman himself. Among his most remarkable works are several winter scenes (Pond in the snow, now in the Chicago Art Institute) which show great sensitiveness and delicacy in rendering the pearly iridescence of snow rather as Sisley and Monet did.
