As for who typically gets credit, yes, I think you'd get a different result if you ask astronomers and astro-physicists who are over 50 years old, or anyone who hung around science museums and planetariums in the 1960's or 70's, or check out old popular science books and magazines, or the Journal for the History of Astronomy October 1983, which takes on the prevailing attitude. Perhaps it's changing, but that's only through the efforts of folks like you, who take the effort to set the record straight.
