Every 12 months, the editors of Art+Auction assemble a list of the individuals who have stood out in the art world over the last year, and publish our results as our Power List. On December 2, we published our Introduction, explaining the thinking that went into this year's list and our process of judging. Today, we offer the sixth of nine installments to be published on ARTINFO, of collectors and donors whose support is creating major advancements in the arts: “Power Patrons.”
