David Hockney is an English painter, graphic artist, photographer, theatre designer, teacher and writer. Born in 1937 in Bradford, England, Hockney began his studies at the Bradford College of Art in 1953, and in 1959 enrolled in the Royal College of Art, London. Throughout the 1960s, Hockney contributed greatly to the Pop art movement, traveled to New York City and met Andy Warhol, and began painting in the relatively new acrylic medium using vibrant colors in realistic ways. Hockney has sound-color synesthesia, but tends not to use it in his artwork in general. He does, however, use it in his construction of stage sets of operas and ballets; he listens to the music of the piece he is constructing a set for and uses the colors he sees in his set designs (Cytowic, 2002). A Royal Academician and Companion of Honour, Hockney is generally considered to be one of the most influential British artists of the twentieth century.
