The Bloombergs
Michael, 60, mayor, and Marjorie Tiven, 58, city commissioner for the United Nations

Before being hired (at $1 a year) by her brother to be City Hall's chief protocol officer, Tiven, a social worker, chatted up the Times about the mayor's boyhood passion for snakes. "There were incidents of snakes' escaping," she said. " 'Have you seen my snake?' he would ask. I remember once looking through the kitchen door and seeing this large snake, several feet long, slithering down the steps." At City Hall, Tiven has worked with the State Department on the dicey diplomatic-parking-violations issue and helped coordinate the comings and goings of 100 heads of state for the 9/11 anniversary. "It's good that diplomats feel they have a close relationship with the mayor, and who better to do that than the mayor's sister?" one source says. "She's one of those high-energy people who get on your nerves a little, frankly."
