The 56th Annual International Red Cross Ball will be hosted by Chairman, Ambassador Mary M. Ourisman and Honorary Junior Mr. and Mrs. Matthew T. Mellon II. The event, which will honor Dina Merrill Hartley with a performance by her grandson Cole Rumbough, continues its more than half-a-century tradition of being among the highlights of the Palm Beach social scene (welcoming ambassadors, dignitaries, government and civic officials and philanthropic leaders from around the world in support of the vital humanitarian mission of the American Red Cross).
