June 6, 2009, New Haven, Conn., The Wall Street Journal — Richard Levin, the longest serving president in the Ivy League, had enjoyed a charmed run at Yale.

Mr. Levin rode the bull market to restore morale, launch a building spree, and strengthen the school in sciences and internationally. Yale dollars even spruced up shabby New Haven.
