ST. LOUIS POST-DISPATCh WEDNESDAY, MAY 17, 1989 7W Robert Maxwell On Their Toes One thing about the party aboard British media mogul Robert Maxwell's yacht: Everybody, but everybody, had to doff their shoes before boarding the plush-carpeted "Lady Ghislaine." Maxwell insisted and his guests cooperated, including Donald Trump (minus Ivana) who has a much bigger yacht and was happy to compare them with Maxwell. Guests sipped champagne, nibbled caviar flown in from Paris on the Concorde, and salmon served from the vessel's stores by shoeless waiters. There was John Tower, former senator and thumbed-down defense secretary; ex-Navy secretary John Lehman, now with Paine, Webber; lawyer Tom Bolan; literary agent Mort Janklow; U.N. envoy Thomas Pickering; Peter Kalikow, owner of the New York Post; Maxwell's daughter, Ghislaine, and Max' niece, Helene Atkin of Macmillan, the publishing house Maxwell recently took over. Maxwell, who weighs about 300 pounds, went over the guest list personally. No one could tell who didn't make the final invitation list but we do know that Martha Smilgis of Time was invited and then disinvited. She wrote the profile of Maxwell for the mag, which he apparently did not like.
