Scopes was forgotten within ten years after the trial. The book he wrote was not a success. His celebrity was that of a flash in the pan.
Again, kids who studied American history in high school or college most likely encountered his name and discussed the evolution issue and the trial with Bryan and Darrow as the chief protagonists. At least that was the case when I was in high school.
I wouldn't doubt that the film "Inherit the Wind" contains some historical inaccuracies. For some reason, they changed the names of Scopes, Bryan, Darrow, and H. L. Mencken in that film, giving them all pseudonyms.
