Campanella, who received a Tony Award nomination in 1962 for best supporting actor for his performance in "A Gift of Time" along with Emmy nominations for Days of our Lives and Mannix, died of natural causes, his daughter-in-law, Sandy Campanella, said.
Campanella received his first Emmy Award nomination for playing private eye Joe Mannix's boss on the first season of the 1967-75 CBS series Mannix. His character's name, Lew Wickersham, was a sly reference to then-McA head Lew Wasserman and Lankershim Boulevard, an entryway to Universal Studios.
However, Intertect, the heartless crime-fighting corporation that Wickersham headed, was written out after the first season as Mannix (Mike Connors) went out on his own, and Campanella's contract was not renewed.
The actor also appeared in the recurring role of Ed Cooper, the ex-husband and father on CBS' One Day at a Time,
