According to George Takei's Facebook page, Emmy-winning actor William Windom, who played Commodore Decker on Star Trek, passed earlier this week. Windom was 88.
"Today we lost a wonderful actor, William Windom, who played Commodore Decker on Star Trek's classic episode, 'The Doomsday Machine'," wrote Takei. "Mr. Windom truly rejoins the 'Constellation' today. May he rest in peace."
Decker reappered in Star Trek New Voyages: Phase II, played again by Windom, who also appeared in films like To Kill a Mockingbird and in the original Brothers & Sisters TV series.
Windom died Thursday of congestive heart failure at his home north of San Francisco, his wife told the Los Angeles Times.
