Julia Koch, widow of mega-wealthy conservative political figure and Kansan conglomerateur David Koch (the couple are shown above, at an Avenue Magazine party in 2014), has been revealed as the record-setting buyer of a pair of co-0p apartments at 4 East 66th Street from the estate of Microsoft co-founder Paul Allen, according to Page Six editor Ian Mohr. Koch also owns a Southampton estate, an Upper East Side townhouse, and most pertinent to this reporter, a duplex apartment at the arguably even-more-exclusive 740 Park Avenue. But that apartment, on a low floor, apparently isn’t enough for the widow Koch, who rose from vendeuse at the dress salon of society designer Adolfo to the richest woman in New York after her marriage to Koch. When the couple was forced from their apartment and into the Mark Hotel in 2016 after a fire in neighbor Ezra Merkin‘s flat, the former Julia Flesher was said to be relieved–she never took to 740. Will she sell now? Stay tuned.
