Helen Crlenkovich (Croatian: Crljenković) (Akron, Ohio, January 14, 1921 - Los Angeles, California, July 19, 1955) was one of the most successful athletes in America and the world on the three-meter springboard and the ten-meter platform. She was a Croatian American known to friends and family as "Klinky." Both of her parents were from Croatia: mother Anka Tomin was from Petrijevci, and father Adam from Banićevac near Cernik. Career Crlenkovich's mother moved to San Francisco in the early 1930s to help Helen realize her dreams to become a swimmer, leaving Helen's sister Kay behind in a New York boarding school. Crlenkovich began participating on the "Fairmont Plunge" swim team at the Fairmont Hotel under the tutelage of Phil Patterson, alongside future swimming and diving stars Ann Curtis, Barbara Jensen, and Patsy Elsener. Her best sports years began in the late 1930s. In 1937, she was the national junior diving champion. She not only became the best American, but also the world springboard and platform diving champion. She was the first female to perform a full-twisting 1½ somersault, also the 2½ tuck, back 1½ layout, inward 1½ pike and reverse 1½ tuck, dives that were previously only performed by men. In July 1939, Crlenkovich won the national three-meter springboard championship in Des Moines. At the Des Moines meet, Marjorie Gestring won the ten-meter platform diving championship, and Esther Williams, for whom Crlenkovich would later serve as a stunt double, won the 100-meter swimming title. Helen was chosen to represent America in the 1940 Olympic Games. All concerned felt that Helen would achieve two gold medals as a minimum. However, because of the onset of the Second World War, the games were cancelled. During this period her dominance of the U.S. women's diving nationals was overwhelming. After defeating Hall of Famer Marjorie Gestring in both indoor and outdoor 3m springboard in 1940, Helen went on to win all for 3 years. She declined an offer to turn professional for per week in 1940 to dive for Billy Rose's Aquacade at the 1940 Golden Gate International Exposition. Esther Williams, who accepted Rose's offer, went on to be discovered by an MGM scout while swimming in the Aquacade. Crlenkovich won National Amateur Athletic Union (A.A.U.) diving championships each year between 1939 and 1941, declining to defend her title in 1942. During a World War II retirement "Klinky", as she was affectionately known, swam in
