Forrest J. [Forry, 4E] Ackerman has died at age 92. He was the editor of "Famous Monsters of Filmdom", a legendary collector, and the world's greatest Science Fiction fan. In fandom he was both honored and excoriated for having coined the term "Sci-Fi" [which some FAANs derisively pronounce "Skiffy"]. At his home, "the Akermansion", he housed the world's largest collection of science fiction memorabilia. Rest assured, fandom will be memorializing this man for months -- he was the greatest of them.
