Why does Nicholas Grimshaw have a chance at turning around the fortunes of London’s Royal Academy? “He brings more than enthusiasm. As a respected architect, best known here for designing the Eurostar terminal at Waterloo Station, Mr. Grimshaw is already more of a public figure than his three predecessors. Further, unlike the artists who make up most of the academy, he knows how to run a business, in his case a 100-member firm with offices in London, New York and Melbourne, Australia. There is also a vacuum waiting to be filled.”
