Richard Dorment doesn’t do whimsy. Or Stanley Spencer. He’s a fan of Cy Twombly and Brice Marden, Gilbert and George and Mark Wallinger, Rachel Whiteread and Susan Hiller. He loves writing about contemporary art. And he worked as art critic of the Daily Telegraph for 25 years. Like the grit in the oyster he irritated the establishment, producing pearl after pearl that occasionally had even his own paper distancing itself from his opinions.
