The end of an era is at hand. Yesterday it was announced the New Yorker‘s longtime architecture critic, Paul Goldberger, will be leaving the magazine he’s called home for the past 15 years for greener, more ad-heavy pastures, to become a contributing editor at Vanity Fair. The two magazines are, of course, both owned by Conde Nast, meaning the move isn’t a tremendous hike, and Goldberger has a history with VF, having contributed pieces here and there over the years. Still, it’s something of a major in-house coup, which the Observer has plenty of juicy details on, including that the critic hadn’t been getting along with New Yorker editor David Remnick, who he claims made getting stories into the magazine much more difficult, and that his decision to leave was in part related to a biography of Frank Gehry he’s in the middle of working on. On the Vanity Fair side, here’s what the magazine’s triumphant editor Graydon Carter had to say:

“This is an appointment that thrills me profoundly,” Carter said. “Paul is about as gifted a commentator on architecture, urban planning, and design as anyone you’re going to find these days—in other words, he’s just a brilliant writer.”
