Today, most Olympic fans in the United States are proud of Michael Phelps, who has broken records for both swimming and amount of gold medals won in one Olympic game.
But in the 1920s, the same pride and idolization was for another swimmer: Johnny Weissmuller, one of the first international swimming superstars.
Weissmuller is best known now for swinging through trees with his signature yodeling yell and speaking in broken English in the film role of Tarzan the Ape man. But his fame began as an Olympic swimmer.
