Major Abstract Expressionist Jackson Pollock, dubbed "Jack the Dripper" by Time magazine in 1956, is best known for his large "action" or drip paintings of 1947–52, formed by pouring and manipulating liquid paint atop canvases set on the floor. A wholly original, rule-shattering figure in American art, Pollock inspired Frank Stella, Richard Serra, and the Color Field painters. Pollock's early Surrealist works of personal symbols and abstract figures show the influence of José Clemente Orozco, David Alfaro Siqueiros, Pablo Picasso, Paul Klee, Joan Miró, and Max Ernst, as well as his experiences with Jungian psychotherapy.
