Two former residents of 740 Park — Ronald Lauder and Edgar Bronfman — are in the news, duking it out over leadership at the World Jewish Congress, says the New York Post’s Page Six. Lauder recently left his soon-to-be-ex-wife behind in the grand double-duplex apartment 740 developer James T. Lee built for himself. Bronfman’s triplex penthouse, created by Lee for Vanderbilt heir J. Watson Webb and his wife Electra Havemeyer, is now owned by United Technologies chairman George David.
