Peter Kaplin (NOT Peter Kaplan) Buys Louis Auchincloss’ Storied Park Ave Apt

Louis Auchincloss insisted the well-moneyed, well-mannered Manhattan upper crust he chronicled would live forever. “Where is this ‘vanished world’ they talk about?” he once asked. “I don’t think the critics have looked out the window!” But change is inevitable, even for a man who devoted his life to resisting it, and Auchincloss’ Park Avenue apartment has sold to a moneyed financier for $3.905 million.

From a three-bedroom, top-floor apartment in a sedate pre-war on Park Avenue, Auchincloss chronicled a moneyed class that wouldn’t dare live anywhere else. The spot at 1111 Park was one of several properties belonging to the lawyer, novelist and, of course, heir to a fortune, who also insisted that life would not be complete without “an apartment or brownstone in town, a house in the country, having five or six maids, two or three cars, several clubs and one’s children in private schools.” To wit, the building features a fireplace in every apartment and an entry hall in most of them.

Anchincloss died in January and his estate has sold the spot to Karen Adler and Peter Kaplin — not, in fact, The Observer‘s other favorite chronicler of the Manhattan well-to-do, he of the nearly identical name. No, this is simply another wealthy Wall Street-type. The apartment, listed by Brown Harris Stevens’ Mary Rutherfurd and Leslie Coleman sat on the market for scarcely more than a month in the spring. Change, as they say, happens fast. Peter Kaplin (NOT Peter Kaplan) Buys Louis Auchincloss’ Storied Park Ave Apt
