It's impossible to talk about diving without bringing up the name Greg Louganis. His accomplishments on the board range from five World Championships from either the 3-meter springboard and 10-meter platform, as well as four gold medals and one silver from three different Summer Olympic Games (1976, 1984, 1988).
Of course, as much as Louganis is praised for what he accomplished, you cannot go too long without talking about the time he smashed his head against the springboard at the 1988 Olympics. Even with a concussion and a small gash on his head, Louganis still managed to come away from the competition with the gold.
That same year, Louganis discovered he was HIV positive. However, he didn't come forth with the findings until 1995 when he confessed the news on The Oprah Winfrey Show.
