In 2007, Columbia University received the largest-ever gift from an individual–$400 million for financial aid–from one of its alums, telecommunication mogul, John Kluge. Part of that gift was Kluge’s Palm Beach estate, Casa Sin Nombre or House Without a Name–an extraordinary assemblage of historic properties in one of the resort town’s best sections. The history of Kluge’s homes is the subject of my latest Unreal Estate column in Avenue magazine.
