David Hockney (b. 1937) is an English painter, printmaker, stage designer and photographer. He studied at Bradford School of Art and later the Royal College of Art. A significant change in his approach occurred after his move to Los Angeles, California at the end of 1963, when his work began to reflect American life. Much of his work contains references to popular culture, with the Californian swimming pool as one of his favourite subjects. He was an important contributor to the British Pop Art movement of the 1960s, and is considered one of the most influential artists of the twentieth century. Hockney has exhibited extensively in the UK and internationally, most recently at the Royal Academy of Arts, London.
