In this Friday, Sept. 3, 2010 photo, Harvard history professor and author Niall Ferguson attends the "Intelligence on the World, Europe, and Italy" economic forum, at Villa d'Este, in Cernobbio, on Como Lake, Italy. Ferguson is apologizing for saying economist John Maynard Keynes didn't care about the future because he was gay and had no children. Ferguson made the remarks on Thursday, May 2, 2013, during a question-and-answer session after a prepared speech at the Altegris Strategic Investment conference in Carlsbad, Calif. Asked to comment about Keynes, he suggested that the British economist's philosophy was shaped by being homosexual and therefore childless. (AP Photo/Luca Bruno) less
