Sad to report the passing of Stephen Furst, who joined St. Elsewhere in season two as a recurring character, playing medical student Elliott Axelrod, and then joined the main cast for season three onwards. The cause of death is reported as complications from diabetes.Furst is probably best known for his pre-St. Elsewhere role as the naive fraternity pledge Flounder in the great college movie, National Lampoon's Animal House. He later appeared on Babylon 5 in the 90s, and worked extensively as a voice-over actor.
Here are a couple of news stories from elsewhere on the web:
