American, 1883-1935. Charles Demuth's work in watercolors and the simplistic linear style was his signature but his exacting images of the industrial landscape of the early 20th century in Pennsylvania and New York served as the foundation for the Percisionist movement. Heavily influenced by Cubism, Demuth helped develop a style of painting with crisp lines and shapes to define objects and space, called Percisionism. Like his friend Georgia O'Keefe, he applied this to natural subjects as well. Some of Demuth's best known works are of plants and flowers. Sadly Demuth was never in good health and died at age 52. He produced hundreds of works over his career and left most of them to O'Keefe.
