P.T. Sandover is the main antagonist of the Supernatural episode "It's a Terrible Life". He was the owner and founder of Sandover Bridge and Iron. After he died, he returned as a ghost.
He was portrayed by John Hainsworth.
Born 1841, he was a workaholic, who had no wife or kids to speak of. He used to say he was the company, and that his very blood pumped through the building. His office was room 1444 until he died in 1916 at the age of 75.
His spirit is woken in times of great economic distress. He "zaps" the employees of the company who are poor workers and turns them into model employees, the perfect worker-bees. They become so dedicated that when they inevitably fail they kill themselves. He began attacking employees in 1929 during the Great Depression, when 17 people committed suicide by jumping from office windows.
Dean Smith and Sam Wesson (alternate reality versions of Dean and Sam Winchester) manage to destroy Sandover's spirit, which was haunting the company's building, by burning a pair of gloves that contained the last of his remains.
