Gertrude Ederle was the first woman to swim the English Channel in 1926. During her famous swim the water became very rough and her coach yelled at her to get out of the water. She replied, "What for?" Not only was she the first woman to swim across the English Channel, she also set the world record at the time for doing so beating the previous time by about two hours. People at that time thought no woman would ever be able to swim across the English Channel, only five men had been able to do so before her.
