PALM SPRINGS, Calif. (KTLA) -- Actor Tom Bosley, best known as the beloved Mr. Cunningham on "Happy Days," has died.
The family says Bosley died of heart failure at 4 a.m. Tuesday at a hospital near his Palm Springs home.
Bosley's agent, Sheryl Abrams, says he was also battling lung cancer.
He was 83 years old.
Bosley was most known for his role as Howard Cunningham on the long-running sitcom 'Happy Days.'
TV Guide ranked Bosley's "Happy Days" character No. 9 on its list of the "50 Greatest TV Dads of All Time" in 2004.
The show debuted in 1974 and ran for 11 seasons.
He was also known for portraying Sheriff Amos Tupper on "Murder, She Wrote" and Father Frank Dowling on the TV mystery series, "Father Dowling Mysteries," which ran from 1989 to 1991.
Actor/Director Ron Howard sent this statement Tuesday:
I'm so saddened by the loss of our wonderful Tom Bosley. Remarkable on so many levels, Tom's insight, talent, strength of character and comic timing made him a vital central figure in the Happy Days experience.
A great father and husband, and a wonderful artist, Tom lead by example, and made us all laugh while he was doing it.
My last conversations with Tom reflected the love of life and peace of mind that he always maintained throughout his full and rewarding life.
I miss him already.
Actor Henry Winkler, who played Arthur Fonzarelli on 'Happy Days' says he's shocked to hear the news.
"I'm just in shock, I really am," Winkler told KNX 1070 News Radio.
"I spoke to him just a few weeks ago and he seemed to be getting his strength back," he said.
When he was first offered the costarring role in "Happy Days,"
a series about teenage life in the 1950s, he turned it down.
"After rereading the pilot script," he recalled in a 1986
interview, "I changed my mind because of a scene between Howard
Cunningham and Richie. The father/son situation was written so
movingly, I fell in love with the project."
Propelled by the nation's nostalgia for the simple pleasures of
the 1950s, "Happy Days," which debuted in 1974, slowly built to
hit status, becoming television's top-rated series by its third
