Stuart Damon, an actor known for playing Dr. Alan Quartermaine in "General Hospital," has died at the age of 84.
His death was confirmed to Fox News by the star's son Christopher.
Damon had been struggling with renal failure for five years and "in the end, it was multiple complications on top of kidney challenges," Christopher said of his father's death, which occurred early Saturday morning at the Motion Picture Television Fund retirement community in Los Angeles where he'd lived for seven years.
The actor starred in nearly 400 episodes of the long-running ABC soap opera, per IMDb, appearing as a ghost every so often after his character's death in 2007.
