Gunsmoke star dead at 83

For millions of Americans, Gunsmoke wasn’t just a television program — it was a weekly ritual. And now, fans are mourning the loss of one of the actors whose quiet presence helped make Dodge City feel like home.

Roger Ewing, the tall, soft-spoken performer who portrayed deputy marshal Thad Greenwood during the 1960s, has died at the age of 83. His family confirmed that Ewing passed away on December 18 at his longtime home in Morro Bay, California, according to The Hollywood Reporter.

Standing 6-foot-4 with a rugged, easygoing demeanor, Roger Ewing first appeared on Gunsmoke in February 1965 in the episode “Song for Dying,” playing a character named Ben Lukens. Just months later, viewers met Thad Greenwood, who debuted in the third episode of season 11. At only 23 years old, Ewing quickly became a familiar and reassuring presence on the long-running CBS western.

 

Thad was written as the son of an elderly Oklahoma sheriff, portrayed by Paul Fix, who comes to Dodge City seeking the men responsible for his father’s fatal heart attack. Although his warrant could not be enforced in the town, events led to the suspects being killed or captured for cattle theft. With his mission complete, Marshal Matt Dillon — played by James Arness — invited Thad to stay on as a deputy.
