At 78, Hockney is one of the rare contemporary artists who truly needs no introduction. Rarer still, he is beloved by the general public, for his lush landscapes, his blazingly cool depictions of L.A., and his astute portraits. He has spent more than half a century gallivanting from one medium to another, taking up photography, stage design, and even iPad drawing in recent years, thanks to an app called Brushes, earning fans all along the way. via ArtNews
