It was long established that the original Narrator or Spaceship Earth was Vic Perrin. Some years ago, Marty Sklar stated this was incorrect and that the narrator was actually Lawrence Dobkin, who had narrated the Hall of Presidents as I recall. This is documented in the Spaceship Earth article in Wikipedia.
Despite this fact coming from a rather reliable source, I think it is incorrect. The voice on the recordings sounds exactly like Vic Perrin. (They are available to watch on YouTube.) To give you an idea of who that is, he was the opening narrator on the original "Outer Limits" TV series. He also was the voice of Nomad in the Star Trek Episode, "The Changeling." Or if you have Netflix, watch the opening scene from the Star Trek episode, "Mirror Mirror." He is the Halkin leader. Much different voice compared to what you hear from Lawrence Dobkin in the other attractions.
