It was the television moment replayed over and over, causing cringes and gasps the world over. In the preliminary rounds of the 1988 games in Seoul, American diver Greg Louganis bounded off the springboard into a reverse 2 1/2 pike, only to hit the back of his head on the board and flop into the water. Everyone watching was shocked as the athlete was helped out of the water. Then, in a stunning turn of events, Louganis, though suffering from a concussion, finished the preliminaries and went on to repeat the same dive in the finals. He earned near-perfect scores, the gold medal, and the admiration of the world for his guts and coolness under pressure. Louganis ignited controversy years later when he revealed he was gay and was HIV-positive at the time of the Games. However, Louganis continues to be a memorable Olympics athlete, showing that nothing can stop someone determined to win.
