But she was somehow never forgotten though mostly out of the public eye for years. She and Avalon staged a reunion in 1987 with "Back to the Beach." It was during the filming that she noticed she had trouble walking — the first insidious sign of MS.
When it was finally diagnosed, she later recalled, "I knew nothing about (MS), and you are always afraid of the unknown. I plowed into books."
Her symptoms were relatively mild at first, but gradually she lost control of her legs, and she feared people might think she was drunk. So she went public with her ordeal in 1992.
She wrote of her triumphs and struggles in her 1994 autobiography, "A Dream Is a Wish Your Heart Makes"— the title taken from a Disney song. In 1995, she appeared briefly in a television docudrama based on her book. And she spoke openly about the degenerative effects of MS.
"My equilibrium is no more; it's just progressively getting worse," she said. "But I thank God I just didn't wake up one morning and not be able to walk. You learn to live with it. You learn to live with anything, you really do."
"I've always been religious. This just makes me appreciate the Lord even more because things could always be worse. I know he will see me through this."
Funicello was born Oct. 22, 1942, in Utica, N.Y., and her family moved to Los Angeles when she was 4. She began taking dance lessons the following year and won a beauty contest at 9. Then came the discovery by Disney in 1955.
"I have been blessed to have a mentor like Walt Disney," she said 40 years later. "Those years were the happiest of my life. I felt that back then. I feel the same today."
Asked about the revisionist biographies that have portrayed Disney in a negative light, she said, "I don't know what went on in the conference rooms. I know what I saw. And he was wonderful."
In 1965, Funicello married her agent, Jack Gilardi, and they had three children, Gina, Jack and Jason. The couple divorced 18 years later, and in 1986 she married Glen Holt, a harness racehorse trainer. After her film career ended, she devoted herself to her family. Her children sometimes appeared on the TV commercials she made for peanut butter.
The beach films featured ample youthful skin. But not Funicello's.
She remembered in 1987: "Mr. Disney said to me one day, 'Annette, I have a favor to ask of you. I know all the girls are wearing bikinis, but you have an image to uphold. I would appreciate it if you would wear a one-piece suit.' I did, and I never regretted it."
