Dennis Haskins, the actor who played Principal Richard Belding on Saved by the Bell, has died at 75 from Parkinson's disease, a loss mourned by co-stars who remembered his kindness.

Fox News Digital reported that Haskins died Sept. 27 at a hospital in Burbank, California, after a career that made him a familiar face to a generation of television viewers.

The death certificate from the Los Angeles County Department of Public Health, obtained by TMZ and detailed in that reporting, listed Parkinson's disease as the immediate cause. Other significant conditions included irritable bowel syndrome, depression, hypertension, and benign prostatic hyperplasia.

Haskins was born Nov. 18, 1950, in Chattanooga, Tennessee. He is survived by his son, Dustin. His representative confirmed the death and described a man who stayed close to the people who watched him work.

Similar waves of public mourning have followed other entertainment losses, including coverage of Sam Neill's passing at 78.

Haskins' representative told Fox News Digital the news hit hard after more than two decades together.

"It's a tragic loss. Everyone loved Mr. Belding, and those of us who got to know Dennis loved him even more. He was a great person, and he loved, I mean absolutely LOVED his fans. He always had time for them, no matter what. He was my client and dear friend for over 20 years, and I will miss him terribly. I'm heartbroken."

He first played Principal Belding on the Disney Channel series Good Morning, Miss Bliss. That show was later reworked into Saved by the Bell. Haskins carried the role through the original run and Saved by the Bell: The New Class for more than a decade.

His other credits stretched across network television, including The Dukes of Hazzard, The West Wing, 7th Heaven, Mad Men, New Girl, Hot in Cleveland, and It's Always Sunny in Philadelphia. On screen he often stood for order and patience. Off screen his co-stars said the same traits showed up every day.

Families have offered the same steady tributes after sudden losses in entertainment, much like the response when Tommy Detamore died at 70.

Co-stars describe a protective mentor on the set

Elizabeth Berkley, who played Jessie Spano, posted a lengthy Instagram remembrance. She started on the show at 15 and recalled six teenagers figuring out who they were becoming under Haskins' watch.

"I started Saved by the Bell when I was 15 years old. We were six teenagers at such a formative and impressionable time in our lives. Dennis was kind, protective and deeply caring. He gave us space to be ourselves and to figure out who we were becoming, while always making us feel that he was there if we needed him. He treated us as equals, as the professionals that we were. He respected and trusted us. He was an incredible scene partner who cared deeply about the craft, the work, and about us. You could feel it in the way he showed up, both as an actor and as a person. Mr. Belding couldn’t have been anyone else. So much of what made him so loved came from Dennis’s inherent goodness, the same goodness we were lucky enough to receive and be around every day."

Tiffani Thiessen, who played Kelly Kapowski, pointed to the same steady hand during her teenage years on the series.

"Dennis Haskins was a steady presence in my teenage years, the kind of figure who kept us in line while making sure we knew he was in our corner. I will always remember his kindness and be grateful for the memories we as a cast got to share with him. RIP Mr. B."

Mario Lopez, who played A.C. Slater, struck a lighter note while still calling the news a blow. He remembered Haskins as the biggest kid on the set whenever karaoke started.

"Heartbroken to hear about my old friend Dennis Haskins. He played the principal, but Dennis was the biggest kid on the SBTB set. If you knew him, you loved him, and if there was karaoke, you knew Dennis was getting on that mic!"

Those recollections match the pattern seen when other well-known families face loss, including the Chad Lowe family mourning their daughter.

Haskins spent his career playing the adult in the room. The certificate and the tributes now close the record on a performer who treated young co-stars as professionals and still made time for the fans who grew up watching him.

Decent men who show up consistently still leave the deepest mark, on set and off.
