David Hockney (born July 9, 1937) is an English painter, draftsman, printmaker, stage designer, and photographer. He first emerged in the early 1960s during the height of British pop, then moved to Los Angeles in 1964, where he famously painted a series of swimming pool pictures. Alongside the classic genres of portraiture and landscape, he always kept evolving his art, using technologies such as Polaroids, photocopiers and fax machines, digital video, or the iPhone and iPad as tools for his painting. Since his first big survey exhibition, which in 1970 traveled Europe from the Whitechapel Gallery in London, he has been one of the most widely shown and popular artists of our time. Hans Werner Holzwarth is a book designer and editor specializing in contemporary art and photography. His TASCHEN publications include the Collectors Editions Jeff Koons, Christopher Wool, Albert Oehlen, Ai Weiwei, Georg Baselitz and the David Hockney SUMO A Bigger Book, as well as monographs like the XXL-sized Jean-Michel Basquiat.
