The celebrated financier and author Martin Zweig, who predicted the 1987 stock market crash just days before it happened, had purchased the apartment in 1999 for the then-record-setting price of $21.5 million. He and his wife, Barbara Digan Zweig, filled the space with opulent furnishings and pop-culture memorabilia, including the guitars of major rock musicians, like Jimi Hendrix and Bruce Springsteen, and the team jerseys of sports icons like Michael Jordan and Wayne Gretzky.
Shortly after Mr. Zweig’s death, in February 2013, Ms. Zweig downsized to a smaller, $12 million unit on the 24th floor of the Pierre and put the penthouse up for sale for $125 million. With no takers, the sky-high price tag was lowered several times. In 2015, with the list price at $63 million, the property was removed from the market for six months and the apartment underwent a makeover. The most recent asking price was $57 million.
Mary Rutherfurd and Leslie Coleman of Brown Harris Stevens were the listing brokers. The monthly maintenance is $51,840, according to StreetEasy.com.
Not much is known about the buyer, whose identity was shielded under the limited liability company 795 Properties. Like all purchases in the building, it was all cash. The Pierre, which was once owned by J. Paul Getty, who bought it in 1938 and converted the non-hotel part of the building to a co-op in 1959, does not permit financing.
