Born Roger Lawrence Ewing on January 12, 1942, in Los Angeles, he was a lifelong Gunsmoke fan. In high school, he even performed a parody sketch as Chester, Dennis Weaver’s character. After college and a stint as a lifeguard, Ewing turned to acting, appearing in shows like Bewitched, Rawhide, and films including Ensign Pulver and None But the Brave.

After leaving Gunsmoke, he appeared in Death Valley Days, The Mothers-in-Law, and movies like Smith! and Play It As It Lays. Eventually, Ewing left acting behind to travel the world, pursue photography, and even engage in local politics in Morro Bay, where he ran for city council in 2003.

For Gunsmoke fans, Roger Ewing will always be Thad—the steady, dependable young deputy whose calm presence made Dodge City feel like home. His legacy lives on every Saturday night in the hearts of viewers who grew up alongside him.
