Artist David Hockney has died. He was 88. His paintings of pools shimmering in the Los Angeles sunshine became icons of 20th-century art. He was one of the most popular and critically lauded British artists of the last century. He was born in the north of England but lived much of his life in Southern California, making its sun-drenched suburban views a major motif. Later in life he returned to Europe, finding renewed inspiration in the wooded hills of his native county of Yorkshire and the fields and trees of France’s Normandy region. Hockney’s publicist said Friday that he died at his home in London on Thursday.
