Biographical / Historical

Unknown , sometimes known as Unknown Worlds was begun in 1938 under Street and Smith Publications. It served as a companion publication to Stree and Smith's other science fiction publication, Astounding Science Fiction. The magazine was noted for it's use of combining the mundane with the fantastic, as well as it's frequent habit of stories with more rational, scientific fantasy over magical or mythical fantasy. In 1941 Unknown was changed from a monthly to a bimontly schedule due to lack of sales. It was also at this time that the name was changed to Unknown Worlds. 1943 saw publication cease, due to increasingly intesne paper shortages due to World War II. Despite it's relatively short run of five years, Unknown is hailed as one of the most influencial and well-writen science fiction magazines ever published. Science fiction historian Michael Ashley called is "revolutionary" and noted "Unknown remains one of the best pulp magazines ever published, and almost certainly the most important in the fantasy genre" in his book The Time Machines: The Story of the Science-fiction Pulp Magazines From the Beginning to 1950.
