I was watching the premiere episode of the 1950s series The Adventures of Superman on Me-TV today, and Dabbs Greer appeared near the end in an uncredited role as a man facing certain death hanging onto a rope from a dirigible until he is saved by Superman. As I mentioned, his role was not credited at the end, but I easily recognized his face & voice. He was about 35 years old at the time of filming in 1952.

He was also in an episode of the Twilight Zone called "Valley of the Shadow".

And "Hocus-Pocus & Frisby"
