We are saddened to report the passing of science-fiction author and humorist-satirist Harry Harrison. The creator of the Stainless Steel Rat, featured in 12 novels, Harrison was an early EC comics artist who also wrote the novel Make Room! Make Room!, which was the basis for the movie Soylent Green.

Harry Harrison (born Henry Maxwell Dempsey; March 12, 1925 – August 15, 2012) was an American science fiction author, best known for his character the Stainless Steel Rat and for his novel Make Room! Make Room! (1966). The latter was the rough basis for the motion picture Soylent Green (1973). Harrison was (with Brian Aldiss) the co-president of the Birmingham Science Fiction Group.

Harrison also wrote the Flash Gordon comic strip in the 1950s and ‘60s.

He was 87 years old.
