Haskins' former "Saved by the Bell" co-stars remembered the actor, who became a familiar and reassuring presence during their teenage years on the series.

Elizabeth Berkley, who portrayed Jessie Spano, reflected on the special relationship Haskins had with the young cast.

"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," she posted on her Instagram with a photo of her "Saved by the Bell" co-stars.

"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, also remembered Haskins as a steady presence during her teenage years.

"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."

Haskins was born Nov. 18, 1950, in Chattanooga, Tennessee. He became one of the most recognizable faces of the "Saved by the Bell" franchise, portraying the often-exasperated Principal Belding as he tried to keep Zack Morris, played by Mark-Paul Gosselaar, and his fellow Bayside students in line.

His journey as Mr. Belding began before "Saved by the Bell" officially became a television hit.

Haskins originated the role on the Disney Channel series "Good Morning, Miss Bliss," which was reworked into "Saved by the Bell." He continued playing Belding throughout the original series and later reprised the character on "Saved by the Bell: The New Class," extending his run as the beloved principal for more than a decade.

Haskins became closely identified with the character, whose frequent "Hey, hey, hey, what is going on here?" catchphrase became a signature part of the series as Principal Belding attempted to rein in Morris and his classmates.
