About Helen Stephens
Helen Herring Stephens was an American athlete and a double Olympic champion in 1936. Next, Stephens anchored the American 4 × 100 m relay team that won the Olympic title after the leading German team dropped its baton. She won national titles in both categories. There she won the 100 m final, beating reigning champion and world record holder, Stanisława Walasiewicz (aka Stella Walsh) of Poland. Stephen's time of 11.5 s was below the world record, but was not recognized because a strong tailwind was blowing at the time of the race.
