Between 1952 and 1954, John Raymond published four digest-size science fiction magazines. Raymond was an American publisher of men's magazines who knew little about science fiction, but the field's rapid growth and a distributor's recommendation prompted him to pursue the genre. Raymond consulted and then hired Lester del Rey to edit the first magazine, Space Science Fiction, which appeared in May 1952. Following a second distributor's suggestion that year, Raymond launched Science Fiction Adventures, which del Rey again edited, but under an alias. In 1953, Raymond gave del Rey two more magazines to edit: Rocket Stories, which targeted a younger audience, and Fantasy Magazine, which published fantasy rather than science fiction.
