I am a big John W. Campbell, Jr. Fan. As a person, he seems to have been a jerk, but as an editor, he created modern science fiction. As a writer, he was mostly readable. He’s  known mostly for writing Who Goes There?, which has been made into a movie called The Thing, twice.

History doesn’t always repeat itself. Sometimes it just screams, "Why don’t you listen to me?" and lets fly with a big stick. – John W. Campbell, Jr.
