Marjorie Gestring was a competitive springboard diver from the United States who won the gold medal in 3-meter springboard diving at the 1936 Summer Olympics in Berlin, Germany at the age of 13 years, 268 days—the youngest person ever to win an Olympic gold medal. With the cancellation of the Olympics in 1940 and 1944 due to World War II, Gestring did not get a chance to defend her title, and her comeback attempt for the 1948 Summer Olympics fell short.
