Less than a week after entering contract to buy a penthouse at Jared Kushner’s Puck building, hedge funder David Ganek listed his duplex at 740 Park Avenue for $44 million.
The four-bedroom co-op unit features a library, four fireplaces, two offices and two dressing rooms. Jacqueline Kennedy Onassis — then Jacqueline Bouvier — resided in the unit until she was 7 years old.
Serena Boardman, Robin Stein and Jeremy Stein of Sotheby’s International Realty has the listing.
