Doc Adams’ first name on Gunsmoke was Galen in the television series, and Charles in the original radio series.

  • On TV, Milburn Stone played Dr. Galen Adams, the gruff but kind town doctor in Dodge City.
  • In the earlier radio version, Howard McNear played Dr. Charles Adams, also known simply as “Doc.”

So if you’re thinking of the classic TV episodes, his first name was Galen.
