A new downtown-party crowd coalesced around the Upper East Side in spring 1965

Evidence

More than Baby Jane, twenty-two-year-old, old-money Edith Minturn Sedgwick was zeitgeist-made material, heavy into diet pills and, like Barbara Rubin, a graduate of the Connecticut psychiatric hospital Silver Hills. Unlike the Park Avenue princess Baby Jane, Edie was emblematic of a new Upper East Side that came together in the spring of 1965 when the supremely fashionable discotheque Arthur opened on the site of the old El Morocco on East Fifty-Fourth Street and another disco, the Phone Booth appeared on East Fifty-Fifth Street, the former site of the Blue Angel supper club. — J.
