Lloyd Blankfein’s memo to Goldman Sachs employees was clear: Keep a low profile. Director Richard Kimball took the edict to heart. When he hosted parties this summer where some of the lady guests took their tops off in gratitude, did he do it on the street where everyone could see him? Please, that would be absurd. No, he held them in the privacy of his Southampton rental. If the cops showed up, as they did occasionally, he probably even refrained from passing out his business card. Now, a tipster tells Dealbreaker (which uses its “unfounded rumor” disclaimer) that Kimball showed the same amount of class and discretion when it came to his two-story penthouse on Jane Street.
