Von Bargen died on Sunday in the Cincinnati area, Harry Gilligan, owner of Gilligan Funeral Homes, confirmed today.
Gilligan said he couldn't provide the cause of death, names of relatives or any other information. WLWT-TV in Cincinnati first reported the death.
In addition to his "Seinfeld" role, von Bargen portrayed Commandant Edwin Spangler on "Malcolm in the Middle." His film credits include "The Silence of the Lambs," "O Brother, Where Art Thou?" and "Lord of Illusions." He also had appearances on "Law & Order," ''The West Wing" and "NYPD Blue."
"He was much loved, for himself and his work, both of which were unassailable," Colonna wrote.
Von Bargen made headlines in 2012 when he called 911 after shooting himself in the temple. He told police he was supposed to go to a hospital that day to have some toes amputated because of diabetes complications and had already had one leg amputated. He said he was feeling depressed before he shot himself.
