(NEXSTAR) – Jan Schwieterman, an actor known to Nickelodeon fans as the villain from the “Good Burger” film adaptation, has died at the age of 52, his family announced.

His date of death was listed as Feb. 28 in an online obituary.

“It is with a heavy heart that I share the passing of my brother, Jan (JP) Schwieterman,” the actor’s brother Chad Schwieterman wrote in a Facebook post earlier this month, revealing that Schwieterman had only “recently” been diagnosed with “an aggressive form of stage 4 cancer.”

“Please keep our family in your thoughts and prayers as we navigate this difficult time,” the post concluded.

As an actor, Schwieterman only has a handful of credits to his name on IMDb, though they include roles on such shows as “ER,” “Beyond Belief: Fact or Fiction,” and “Felicity.”

Perhaps his biggest role came in 1997 when he starred opposite Kenan Thompson and Kel Mitchell in “Good Burger,” the film adaptation of Thompson and Mitchell’s sketch from the Nickelodeon TV series “All That.”

Schwieterman played Kurt Bozwell, the film’s antagonist and the owner of rival restaurant Mondo Burger.

Schwieterman’s final film credit on IMDb is listed as 2007’s “Along the Way.” His LinkedIn page suggested that he had retired from acting and worked as an IT professional specializing in security. His obituary also indicated photography, martial arts, and painting.

A memorial was held for Schwieterman earlier this month in Berger, Missouri, near his birthplace of Hermann. He’s survived by three siblings and both parents, according to his obituary.
