The star was best known for her role as Jambi the Genius in Pee-wee’s Playhouse.
TMZ says the Riverside County Coroner has confirmed his death and says he died in April, but the cause of death is unclear at this point.
In his role as Jambi the Genius, John’s face appeared in a jewelry box whenever the show’s main character, Pee-wee Herman, wished for something.
John would appear dressed in blue makeup with a red and gold turban as he portrayed the sassy character.
In addition to the genius, John was also the voice of Pterri the Pterodactyl in the series.
He also wrote several episodes for the hit series and worked alongside Paul Reubens to create the screenplay for Pee-wee’s Playhouse: Christmas Special in 1988.
The production earned her an Emmy nomination for Best Writing in a Children’s Special.
Other TV appearances included parts of Seinfeld, while he was on the big screen in films such as The Frog Prince, Eating Raoul and Echo Park.
Playhouse operated in the United States from 1986 to 1991, and John reprized his popular genius role in the Broadway adaptation of The Pee-wee Herman Show in 2010.
His most recent experience came as an idea man for Walt Disney Imagineering for improvised performances in Disney theme parks.
The 66-year-old was born in Alaska, but grew up and attended schools in Colorado.
His acting career began when he was part of a Los Angeles-based improv group called The Groundlings. There he performed alongside Paul Reubens and Phil Hartman.
Friends and fans of the actor took to social media to send condolences.
Screenwriter Michael Varrati wrote on Twitter: “Sad to hear that John Paragon, known for his role as Jambi the Genie, has passed away.
“Cult filmmaker and figure in his own right, I was lucky to have done a concert with him some time ago where he was courteous and tolerant of my old-fashioned questions.
Another fan took to the site to thank the star, writing, “Thank you for remembering an essential part of my childhood. I still attribute my taste for the odd to Pee Wee’s gambling den as an early influence. This is such a lovely quirky TV piece! RIP John Paragon! “
And a third sentence: “John Paragon was a BIG part of my childhood. I’m so glad I saw him play Jambi on “The @PeeWeeHerman Show” live while touring Los Angeles a few years ago. Tonight’s news makes me very sad. RIP. ”
