For generations of viewers, Gunsmoke was more than a TV show—it was a familiar place, and Roger Ewing was part of what made it feel lived-in. Best known for playing deputy marshal Thad Greenwood in the mid-1960s, Ewing has died at 83, passing away on December 18 at his home in Morro Bay, California.

Tall, soft-spoken, and quietly dependable, Ewing joined the series in 1965 and quickly became a reassuring presence in Dodge City. His character, Thad, was written as a young man who found a new family in Matt Dillon and the town’s core cast, filling gaps not with bravado but steadiness.

Though he appeared in about 50 episodes before his role was phased out, Ewing left a lasting impression. He later reflected fondly on how naturally he fit into the ensemble, embodying a kind of everyday reliability that anchored the show during a transitional period.

After Gunsmoke, Ewing continued acting briefly before stepping away to pursue photography, travel, and local civic life. For fans, however, he will always be remembered as Thad—the quiet deputy who didn’t seek attention, but earned trust, and helped make Dodge City feel like home.
