Stephen Furst, perhaps best known as Flounder in Animal House, died Friday from complications with diabetes. He was 63. His two sons Nathan and Griffith Furst announced the news on the actor's Facebook page, paying tribute to their "brilliant and prolific actor and filmmaker" father.
"Steve has a long list of earthly accomplishments," his sons said in the post. "He was known to the world as an brilliant and prolific actor and filmmaker, but to his family and many dear friends he was also a beloved husband, father and kind friend whose memory will always be a blessing."
The actor was also known for playing the role of Dr. Axelrod in the 1980s medical TV drama St. Elsewhere, and later as Vir Cotto in Babylon 5, which he occasionally directed as well.
After his breakout role of Kent "Flounder" Dorfman in 1978's Animal House, he had several guest appearances on TV shows such as Newhart, CHiPS and The Jeffersons until he landed the role on St. Elsewhere, which aired from 1982-1988.
