For millions of Americans, Gunsmoke wasn’t just a television program — it was a weekly ritual. Fans are now mourning the loss of Roger Ewing, the actor whose quiet steadiness as deputy marshal Thad Greenwood helped make Dodge City feel like home. Ewing died on December 18 at age 83 at his home in Morro Bay, his family confirmed.

Standing 6-foot-4 with an easygoing presence, Ewing first appeared on Gunsmoke in 1965 before returning as Thad Greenwood in season 11. Thad was written as the son of an Oklahoma sheriff and, after events brought him to Dodge City, James Arness’s Marshal Matt Dillon invited him to stay on as a deputy. Ewing later said the role fit naturally: with his character’s family gone, the town’s regulars became his own, and Thad was always there to help when needed.

Ewing appeared in roughly 50 episodes through 1967, during a brief ratings dip. When the show rebounded, his role was gradually phased out and later replaced by Buck Taylor’s Newly O’Brien. Born Roger Lawrence Ewing in Los Angeles in 1942, he had been a fan of the series long before joining it. His early career included guest spots on Bewitched, Rawhide, and appearances in films such as None But the Brave alongside Frank Sinatra.

After Gunsmoke, Ewing continued acting in television and film and was even considered for a lead in Midnight Cowboy before the role went to Jon Voight. He eventually stepped away from acting, reinventing himself as a photographer, traveling widely, and later becoming active in local politics.

For Gunsmoke fans, Roger Ewing will always be Thad — dependable, unflashy, and reassuring. For those who spent their Saturday nights in Dodge City, his presence remains part of what made the town feel like home.
