Donald Trump/Mark Etess. Billionaire Trump always wanted to do things bigger and better - and to generate maximum publicity for himself and his organization in the process. Aware of how much boxing had served to "brand" Caesars Palace in Las Vegas after its 1966 opening, Trump poured his considerable resources into doing the same for his casino properties in Atlantic City in the 1980s. Toward that end, The Donald made one of his more astute hires, Mark Grossinger Etess, to run a burgeoning boxing operation that featured, among others, the sport's biggest draw, undisputed heavyweight champion Mike Tyson. Etess' death, along with those of two other Trump executives, in an Oct. 10, 1989, helicopter crash, had as much or more of a detrimental effect on Trump boxing as did the boss' worsening cash-flow problems.
