David Hockney (born 1937) is one of the most influential 20th century British artists. He has explored a diverse range of techniques over the years including painting, printmaking, drawing, set design, videography, photography and digital art. He was an innovative printmaker with technology early in his career which has gained recent traction again drawing on his iPhone and iPad. Hockney explores everything from still life and domestic scenes to portraits and landscapes, whilst also addressing themes in his own life such as sexuality. Hockney’s style is iconic and recognisable with its warm feeling and lively, colourful palette. In 2018, Hockney’s Portrait of an Artist (Pool with Two Figures) became the most expensive artwork by a living artist to be sold at auction when it sold in New York for $90 million. Hockney’s work is held in countless international collections and museums.
