Eric Frank Russell (January 6, 1905 – February 28, 1978) was a British author best known for his science fiction novels and short stories. Much of his work was first published in the United States, in John W. Campbell's Astounding Science Fiction and other pulp magazines. Russell also wrote horror fiction for Weird Tales and non-fiction articles on Fortean topics. To 1955 several of his stories were published under pseudonyms, at least Duncan H. Munro and Niall(e) Wilde.
Russell was born in 1905 near Sandhurst in Berkshire, where his father was an instructor at the Royal Military College. Russell became a fan of science fiction and in 1934, while living near Liverpool, he saw a letter in Amazing Stories from Leslie J. Johnson, another reader from the same area. Russell met up with Johnson, who encouraged him to embark on a writing career. Together, the two men wrote a novella, "Seeker of Tomorrow", that was published by F. Orlin Tremaine in the July 1937 number of Astounding Stories. Both Russell and Johnson became members of the British Interplanetary Society.
Russell's first novel was Sinister Barrier, cover story for the inaugural, May 1939 issue of Unknown—Astounding's sister magazine devoted to fantasy. It is explicitly a Fortean tale, based on Charles Fort's famous speculation "I think we're property", Russell explains in the foreword. An often-repeated legend has it that Campbell, on receiving the manuscript for Sinister Barrier, created Unknown primarily as a vehicle for the short novel (pp. 9–94). There is no real evidence for it, despite a statement to that effect in the first volume of Isaac Asimov's autobiography, In Memory Yet Green.
