Chuck Potthast has tragically passed away, his family has revealed.
The man himself was not a 90 Day Fiance “star” unto himself. But as father of Elizabeth “Libby” Potthast and father-in-law to Andrei Castravet, his role of the franchise has been indelible.
For years, Chuck recoiled at his family’s fighting yet celebrated being a grandfather.
Now, he has died. He was only 64.

Chuck Potthast has died at 64
Late on Sunday, November 23, Elizabeth Potthast took to her Instagram page to reveal that her father has died.
Chuck Potthast reportedly died on November 9.
“Two weeks ago, tragedy struck our family,” Libby revealed in her post.
“And,” she grimly acknowledged, “it has left us completely shattered.”
Elizabeth shared: “My sweet, loving, and caring dad went to heaven.”
“We’re trying to figure out how to navigate our lives,” Elizabeth wrote of her dearly departed father.
“And,” she continued, they are grappling with how to “move forward without him.”
Libby concluded: “Please respect our privacy during this extremely difficult time.”
Obviously, 90 Day Fiance fans are heartbroken over this news.
Elizabeth wisely deactivated her comments under the post. After all, she knows better than most that some “fans” can be cruel — especially at the most somber, vulnerable moments.

Becky posted her own tribute
However, Elizabeth and Chuck Potthast are not the only members of her family whom 90 Day Fiance viewers have seen over the years.
Alongside Libby and Andrei and her parents, Chuck and her homophobic mom, we also got to know her siblings: Charlie, Becky, and Jenn.
Becky Lichtwerch took to her own Instagram page to share a tribute to her late father.
“Two weeks ago on this day,” her post began, “my world became distorted into a place I don’t understand.”
Becky wrote: “My father Chuck went home to be with The Lord. The pain is still more than I can bare so this is all I can write.”
The Potthast family was polarizing — intentionally so, at times, to meet the demands of reality television.
90 Day Fiance fans had their favorites and least favorites.
Most, however, were big fans of Chuck.
He was a man who knew how to play along with the joke, he rearranged his whole life when his daughter’s reality TV career took off, and more than anything else, he loved his family.
This is a devastating loss. It is also a surprise, as Chuck was only 64.

What was Chuck Potthast’s cause of death?
The Potthast family did not initially disclosed Chuck’s cause of death.
We know that he had health struggles over the years. In 2016, Chuck waged a cancer battle — but was cancer-free by 2017.
This past summer, Chuck underwent surgery to remove a mass that he feared was a tumor. Fortunately, it was an unusually large kidney stone.
In September, Chuck went under the knife to fix hernias that had stemmed from past surgeries. At the time, he reported that all was well.
Followers have not seen an update from the late reality TV personality since October 3, more than a month before his death.
Our hearts go out to the entire Potthast family at this time.
