Forrest J. Ackerman (1916–2008) was an American science fiction editor and agent. Long active in science fiction and fantasy fandom, he founded the magazine Famous Monsters and worked to promote the abbreviation "sci-fi," which gradually became a common label for science fiction culture. Two of his works are included here: Out of This World Convention and Micro-Man. The former centers on science fiction fan gatherings and convention culture, while the latter, as its title suggests, involves imaginative themes of microscopic or miniature figures; both reflect his enduring interest in genre literature and popular culture. Public information on his educational background, specific positions, and awards is limited, so no speculation is made here. His editorial and agency work, along with his experience founding the magazine, had a certain influence on the development of American science fiction fandom in the twentieth century.
