William Windom was an American actor. He is perhaps best known for his work on television, including several episodes of The Twilight Zone; playing the character of Glen Morley, a congressman from Minnesota like his own great-grandfather and namesake in The Farmer's Daughter; the character of John Monroe on the sitcom My World and Welcome to It, for which he won an Emmy Award for Best Actor in a Comedy Series; as Commodore Matt Decker, commander of the doomed U.S.S. Constellation in the Star Trek episode "The Doomsday Machine"; the character Randy Lane in the Emmy-nominated Night Gallery episode "They're Tearing Down Tim Riley's Bar" and perhaps that of the most common recurring character on the Emmy-winning series Murder, She Wrote, Seth Hazlitt.
