Harry Harrison (born March 12, 1925) is an American science fiction author best known for his character the Stainless Steel Rat and the novel Make Room! Make Room! (1966), the basis for the film Soylent Green (1973). He is also (with Brian Aldiss) co-president of the Birmingham Science Fiction Group.
Before becoming an editor, Harrison started in the science fiction field as an illustrator, notably with EC Comics' two science fiction comic books, Weird Fantasy and Weird Science. He has used house names such as Wade Kaempfert and Philip St. John to edit magazines, and has published other fictions under the names Felix Boyd, Leslie Charteris, and Hank Dempsey (but see Personal Life below). Harrison also wrote for syndicated comic strips, creating the Rick Random character. Harrison is now much better known for his writing, particularly his humorous and satirical science fiction, such as the Stainless Steel Rat series and the novel Bill, the Galactic Hero (which satirises Robert A. Heinlein's Starship Troopers).
During the 1950s and '60s, he was the main writer of the Flash Gordon newspaper strip. One of his Flash Gordon scripts was serialized in Comics Revue magazine. Harrison drew sketches to help the artist be more scientifically accurate, which the artist largely ignored.
Not all of Harrison's writing is comic, though. He has written many stories on serious themes, of which by far the best known is the novel about overpopulation and consumption of the world's resources Make Room! Make Room! which was used as a basis for the science fiction film Soylent Green (though the film changed the plot and theme).
Harrison for a time was closely identified with Brian Aldiss. The pair collaborated on a series of anthology projects. Harrison and Aldiss did much in the 1970s to raise the standards of criticism in the field.
In 1990 Harrison was professional Guest of Honour at ConFiction, the 48th World SF Convention, in The Hague, Netherlands, together with Joe Haldeman and Wolfgang Jeschke.
Harrison is a writer of fairly liberal worldview. Harrison's work often hinges around the contrast between the thinking man and the man of force, although the "Thinking Man" often needs ultimately to employ force himself.
