LOS ANGELES (AP) – Whether he played a small-town sheriff, a murder-solving priest or the father of 1950s teens in 'Happy Days', the show that made him famous, Tom Bosley was a warm and comforting presence on TV sets in America and around the world .

Bosley, best known as the often flustered but always fatherly Howard Cunningham on 'Happy Days', died on Tuesday in Palm Springs. He was 83.

Bosley earned a place as one of the most memorable dads in TV history as the hardware store owner, father to Richie and Joanie Cunningham and landlord to Arthur (Fonzie) Fonzarelli on the long-running sitcom.

Bosley died suffering heart failure at a hospital, his agent Sheryl Abrams said. He also had lung cancer.

His death brought fond remembrances of the nostalgic ABC show, which ran from 1974 to 1984. On Saturday, American TV viewers lost another surrogate parent, Barbara Billingsley, who portrayed June Cleaver in 'Leave It To Beaver'.

Both shows showcased life in the 1950s – before Vietnam, Watergate and other tumultuous events of the '60s and '70s that rocked the US.

"Kids were watching their parents grow up, and parents were watching themselves grow up. And that was the key to success of that show," Bosley said in a 2000 interview.

Bosley initially turned down the role.

"I changed my mind because of a scene between Howard Cunningham and Richie," he said in 1986. "The father-son situation was written so movingly, I fell in love with the project."

Viewers did too.

'Happy Days', which debuted in 1974, slowly built to hit status, becoming US television's top-rated series by its third season.

TV Guide ranked Bosley's Howard Cunningham character at number nine on its list of the '50 Greatest TV Dads of All Time' in 2004.

"A great father and husband, and a wonderful artist, Tom led by example, and made us all laugh while he was doing it," said a statement from Oscar-winning director Ron Howard, who played Richie Cunningham.

"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," Howard said.

"He was my husband for 11 years and the father of the company in many ways," said Marion Ross, who played his wife Marion Cunningham on the show. "He was so smart he could fix the end of a joke or a scene on the spot. We made a perfect couple. I played piccolo to his tuba."

Angela Lansbury played Bosley's unfaithful wife in the 1964 Peter Sellers film 'The World of Henry Orient'. Then, from 1984 to 1988, Bosley played a recurring role in Lansbury's long-running TV series, 'Murder, She Wrote', as folksy Sheriff Amos Tupper.

"He was a wonderfully interesting actor, and very much a part of the early success of 'Murder, She Wrote'. Working with him in the early days of the show gave me tremendous confidence," Lansbury said.

Bosley also played the crime-solving priest in television's 'The Father Dowling Mysteries', which ran from 1989 to 1991.

'Happy Days' also made a star of Henry Winkler, who played "the Fonz", the hip-talking, motorcycle-riding hoodlum who lived upstairs from the Cunninghams.

"Tom was a family member, both on and off the sound stage. We acted together, traveled together and played charades together," Winkler said in a statement. "He was a loving husband, a doting father and a fantastic grandfather.

Although 'Happy Days' brought him his widest fame, Bosley had made his mark on Broadway 15 years before when he turned in a Tony Award-winning performance in the title role in 'Fiorello!' the story of New York's colorful reformist mayor of the 1930s and 1940s

After failing to duplicate his success in 'Fiorello!', Bosley moved to Hollywood in 1968. He would not return to Broadway until 1994 when he originated the role of Belle's father in Disney's production of 'Beauty and the Beast'.

In Hollywood, the character actor found steady work appearing in the occasional movie and as a regular on weekly TV shows starring Debbie Reynolds, Dean Martin, Sandy Duncan and others.

During the 1990s, Bosley toured in 'Beauty and the Beast' and 'Show Boat', playing Captain Andy in the latter.

Bosley made only a handful of theatrical movies. Among them: 'Love With the Proper Stranger', 'Divorce American Style', 'The Secret War of Henry Frigg', 'Yours, Mine and Ours'.

Born in Chicago in 1927, Bosley served in the Navy before returning to his hometown to study at DePaul University. Intrigued with acting, he enrolled at the Radio Institute of Chicago and began appearing in radio dramas.

Bosley married dancer Jean Eliot in 1962 and the couple had one child, Amy. Two years after his wife's death in 1978, Bosley married actress-producer Patricia Carr, who had three daughters from a previous marriage.
