NBC's "My World and Welcome to It" was based on James Thurber's humorous essays and cartoons, and Windom later toured with a one-man show drawn from the program.
He may have been at least as well known for his numerous guest appearances on several TV shows, including "Star Trek," "The Twilight Zone" and "Night Gallery." He co-starred with Inger Stevens from 1963-1966 on "The Farmer's Daughter."
But it was a recurring role that began in 1998 and lasted for a decade on the CBS mystery "Murder, She Wrote" that may have brought him the most fame.
He played a doctor, Seth Hazlitt, n the imaginary town of Cabot Cove, Me., who was best friends with Jessica Fletcher, the show's star played by Angela Landsbury.
While Windom made his mark in TV, he played the prosecutor in 1962's Academy Award-winning film "To Kill a Mockingbird,." And in 1968 he starred in "The Detective" with Frank Sinatra.
Sci-fi fans would remember Windom as Commodore Decker in the "Star Trek" TV episode "The Doomsday Machine." He reprised the role four decades later for "Star Trek New Voyages."
