Hedgie David Ganek bought the 740 Park duplex where Jacqueline Bouvier Kennedy grew up (in an apartment provided to her father “Black Jack” Bouvier by her grandfather, 740 developer James T. Lee) just before 740 Park was published. Now, having purchased a loft at Jared Kushner‘s renovated Puck Building just after Departures published my story featuring the lavish home, Ganek’s put his 740 unit on the market via Sothebys’ broker Serena Boardman, asking $44 million.
