Verrry Private Private-Equity Kingpin Peels Off Posh E. 79th St. Co-op

“We try to hide religiously. If anyone at Cerberus has his picture in the paper and a picture of his apartment, we will do more than fire that person,” said private-equity kingpin Stephen Feinberg, founder and CEO of Cerberus Capital Management, at last year’s shareholder meeting. “We will kill him. The jail sentence will be worth it.”

Yet Mr. Feinberg, who has never given an interview and whose quiet collection of companies (including, as of last year, Chrysler automobiles) makes an estimated $120 billion annually, did not mask his name on the deed for his nine-room, 4,200-square-foot apartment.

According to city records, he and his wife, Gisela, both massive Republican donors, sold their ninth-floor co-op at 151 East 79th Street last month for $9.1 million, $800,000 above the asking price. The buyers are Elizabeth and Brett Milgrim. Mr. Milgrim, not astoundingly, is managing director at a private-equity firm, JLL Partners.

According to the listing with Elliman’s Stephanie Kanter-Weisberg, who did not return calls to her office, the co-op has two wood-burning fireplaces, four bedrooms, a library and an eat-in kitchen.

How do Mr. Feinberg’s decorative tastes run? “There is little at the office to distract staffers from the business at hand,” a Portfolio profile said last year, “almost no art on the walls, no fancy woodwork.” (As for Mr. Feinberg, still under 50, he was described as sporting “thinning brown hair and a wispy mustache.”)

His apartment probably had interesting guests: Dan Quayle and John Snow are Cerberus’ co-chairmen. (Mr. Feinberg reportedly sent Mr. Snow, a former Treasury secretary, to D.C. to lobby against fuel-economy standards last year; Cerberus, incidentally, is named for a mythical three-headed hellhound.)

It isn’t clear why the executive is leaving his posh co-op, where Brooke Astor’s embattled son, Anthony Marshall, also has an apartment. The sales deed lists his alternate address at 36 East 67th Street, the former Egyptian mission to the U.N. When he bought it in 2003 for $19.75 million, that mansion had been outfitted with a small movie theater, a basement sauna, a landscaped roof garden with motorized awning, a ballroom and a massive commercial kitchen.
