Franz Kline (May 23, 1910 – May 13, 1962) was an American painter born in Pennsylvania. He is mainly associated with the Abstract Expressionist movement of the 1940s and 1950s. Kline, along with other action painters like Jackson Pollock, Willem de Kooning, Robert Motherwell and Lee Krasner, as well as local poets, dancers, and musicians came to be known as the informal group, the New York School. Although he explored the same innovations to painting as the other artists in this group, Kline's work is distinct in itself and has been revered since the 1950s.
