Paul Jackson Pollock (; January 28, 1912 – August 11, 1956) was an American painter. A major figure in the abstract expressionist movement, he was widely noticed for his "drip technique" of pouring or splashing liquid household paint onto a horizontal surface, enabling him to view and paint his canvases from all angles. It was called all-over painting and action painting, because Pollock covered the entire canvas and used the force of his whole body to paint, often in a frenetic dancing style.
