On the show Little House on the Prairie, Doc Baker is primarily called just that, Doc Baker. it sometimes gets shortened to Doc, or Doctor Baker, but the characters on the show most often call him simply Doc Baker.
However, Doc Baker’s first name is actually known. His first name is Hiram, although it doesn’t often get used on the television show. We primarily hear it when he is courting someone on the show. The name Hiram is quite old-fashioned, so it was perfectly suited to his character.
Doc Baker was portrayed by Kevin Hagen on the show.
