The wizard that meets the eye is spare and fit; with a long jaw and a carefully coiffed head of silver hair, he looks like a taller, younger Ralph Lauren. A raspy Brooklyn accent betrays his Coney Island origins. He spends an hour and fifteen minutes every day doing advanced yoga with his personal instructor, who travels with him wherever he goes. He is an enthusiastic member of the Trilateral Commission and the Council on Foreign Relations.
He dresses casually – jeans, open-necked shirts, and sneakers – and is rarely seen in a tie. Indeed, those close to him say the reason he quit his board seat at the Rockefeller Institute was that he hated wearing a suit. “It feels like a dress,” he told one friend.
