“Laverne & Shirley,” a spin-off of “Happy Days,” starred Williams and Marshall as roommates who work at a Milwaukee bottling plant. Williams’s character was the more creepy of the pair.
Marshall passed away in 2018 at the age of 75.
Williams also appeared in the 1973 movie “American Graffiti” and the 1974 movie “The Conversation”.
‘Laverne & Shirley’, like ‘Happy Days’, was conceived by Garry Marshall, Penny Marshall’s brother. With his help, Penny Marshall got her breakthrough in the mid-1970s.
The show was one of the most popular on television at its peak. Gary Marshall passed away in 2016.
Henry Winkler, who played The Fonz in “Happy Days,” was one of the grieving Williams.
“Cindy has been my friend and professional colleague since I met her on the set of ‘Happy Days’ in 1975. I have never been in her presence when she was not gracious, thoughtful and kind,” said Winkler.
“Cindy’s talent was limitless. There wasn’t a genre she couldn’t conquer. I’m so glad I got to know her,” he said.
Williams was born in Van Nuys in the San Fernando Valley of Los Angeles.
She had two children, Emily and Zak. They said their mother was devoted to saving animals and her faith, and wanted to make the world smile.
“May that laughter continue in everyone because she would like it,” they said in the statement. “Thank you for loving our mother, she loved you too.”
