(CNN) -- Esther Williams, whose success as a competitive swimmer propelled her to stardom on the silver screen in the 1940s and 1950s, died Thursday in California, her spokesman said.
Williams, known for films that featured synchronized swimming spectacles, was 91.
She grew up in Southern California and was a U.S. swimming champion in freestyle and the breaststroke by her late teens. But her Olympic dreams ended in 1940, when the Summer Games were canceled because of World War II.
"That's one of my sad moments in my life," Williams told CNN's Larry King in November 1999. "It taught me how to live with a sad moment."
Her fortunes turned around quickly.

After an audition, she starred opposite Olympian and film star Johnny Weissmuller in the "San Francisco Aquacade Review," a "Broadway musical in swimsuits," her online biography reads.
MGM then signed her, and she made her movie debut alongside Mickey Rooney in the 1942 film "Andy Hardy's Double Life."
"They did a sequence where I swam with Mickey, underwater kiss, which was my idea," Williams told King. "They didn't think you could kiss anybody underwater without drowning."
Williams went on to appear in more than 20 films through the 1950s, including "Bathing Beauty," "Neptune's Daughter" and "Million Dollar Mermaid," taking many roles that featured her as a swimmer.
She was a 1966 honoree of the Florida-based International Swimming Hall of Fame.
"Her movie career played a major role in the promotion of swimming, making it attractive to the public, contributing to the growth of the sport as a public recreation for health, exercise, water safety -- and just plain fun," her biography on the hall of fame website reads.
