...to whoever made this article. I'd read references to the Visionaries and Professor Z since the original run of DC's Who's Who, but was never able to nail down where they first appeared in the story of Earth-AD. It's amazing how many of these kinds of details occurred in the back-up stories, rather than the main books. I can see why the Great Disaster was retgonned by COIE.
