Alfred Elton van Vogt was a Canadian-born science fiction author regarded by some as one of the most popular and complex science fiction writers of the mid-twentieth century—the "Golden Age" of the genre. van Vogt was born to Russian Mennonite family. Until he was four years old, van Vogt and his family spoke only a dialect of Low German in the home. He began his writing career with 'true story' romances, but then moved to writing science fiction, a field he identified with. His first story was Black Destroyer, that appeared as the front cover story for the July 1939 edtion of the popular "Astounding Science Fiction" magazine.
"Fans are Slans," became the catchphrase of early science fiction fandom in the wake of this novel. Like the Slans - telepathic mutants hiding out in a hostile population - science fiction fans considered themselves a haunted special minority, imbued with transcendent and visionary insight, sure to prevail in the fullness of time.
