Richard Diebenkorn

Richard Diebenkorn is celebrated as a post-war Master in his native United States - Obama even selected one of his works for the private residence of the White House. In Europe though, he's not that well-known. In fact, the only major solo exhibition of his work was at the Whitechapel Gallery back in 1991.
Revolutions often start with a shocking moment or a dramatic gesture, and when David Park backed his car up to the city dump in Berkeley, California, in 1950, maybe that's what he had in mind.
