Cityfile: New York's Most Notable and Influential

Goldman Sachs partners were supposed to be keeping low profiles these days, as per instructions from the bank's CEO, Lloyd Blankfein. And Lord knows anyone related to NYC Prep's PC Peterson—even by marriage—would be well advised to avoid the limelight for a spell. But that didn't stop Richard Kimball Jr., a Goldman partner and the ex-husband of Manny author Holly Peterson, from hosting a series of "rowdy" parties in Southampton over the summer, at least one of which featuring topless women: More

Plenty of reality programs promise to show us how the rich and powerful live their lives. Very few actually end up doing that, of course. The women featured on the Real Housewives of NYC weren't part of the city's social elite before they humiliated themselves on national television—nor were they all housewives either—so they had little to lose in the end. That will change, though, when Bravo's NYC Prep, or the "real-life Gossip Girl," as Bravo has been billing it, debuts on June 23. One of the obnoxious, over-privileged teens featured on the show—the one who comes off in the worst possible light, in fact—hails from one of the city's richest and most respected families. Meet Peter Carey ("PC") Peterson, the grandson of Pete Peterson.  More

Happy Birthday | Considering he's spent the last couple of days fending off accusations he's a slumlord, this probably won't be the most cheerful day for hotel/restaurant owner Eric Goode: He celebrates his 51st birthday today. Others born on the 19th of December: Jake Gyllenhaal is 28 today. Alyssa Milano is 36. Tyson Beckford turns 38. Lady Sovereign is turning 23. Criss Angel turns 41. And real estate developer Doug Durst is turning 64. Weekend birthdays after the jump. More

Not a moment too soon, the prospective first ladies have received some invaluable advice on how to handle life in the White House from Holly Peterson, socialite and esteemed author of The Manny, who appeared on Fox over the weekend just moments after stumbling out of bed, judging by her unbrushed hair and croaky voice. Not that this detracted from the depth of her wisdom, as you'll see.

In this week's issue of Newsweek, heiress/author Holly Peterson shares a few anecdotes about how the very rich are cutting back in these turbulent economic times. The daughter of Blackstone co-founder Pete Peterson, Holly says people are now flying commercial rather than jumping on private jets, women are wearing the same dress twice, and lots of men now seem to have more time on their hands. (The proof: some guys are actually dropping their kids off at school in the morning, a job once relegated to wives and nannies.) "Everyone is just plain scared, but no one is talking specifics," she explains. "The thing about rich people is you never know exactly how rich they are or where their money is." Well, except in the case of her father, of course, who walked away with $1.9 billion in cash when his private equity firm went public last year. [Newsweek via Radar]

Dalton was in the news last week when it was revealed that not a single graduating senior had landed a spot at Harvard. According to Page Six magazine, at Dalton's graduation ceremony last month, "one mom was heard muttering, 'I won't send my grandchildren here, that's for sure.'" Fret not, Dalton parents! A long list of notable people have walked the halls of the posh school, even a few people (like Arden Wohl, left) who don't seem to be famous for any other reason than for wearing unusual headgear and attending lots of parties. A list of other Dalton grads after the jump.More
