Although science fiction had been published before the 1920s, it did not begin to coalesce into a separately marketed genre until the appearance in 1926 of
Amazing Stories, a
pulp magazine published by
Hugo Gernsback. By the end of the 1930s the science-fiction magazine field was booming, with multiple new magazines launched in a short period. Most of the US publishers also printed versions of their magazines for the Canadian market, but with the outbreak of World War II, paper shortages and import restrictions reduced the availability of these magazines in Canada.
Uncanny Tales was begun in response to these conditions; the editor was Melvin R. Colby, and the first issue was dated November 1940. The first issue was
digest-sized, and was printed in green ink. Colby initially focused on
weird fiction, with
Thomas P. Kelley, a Canadian writer whose work had appeared in
Weird Tales, a prolific contributor. In Wollheim's account, he happened to meet Colby early in 1941 in New York; Wollheim had been editing
Cosmic Stories and Stirring Science Stories but both magazines had ceased publication at the time of the meeting. Colby, who worked for a Toronto newspaper, told Wollheim that he was editing
Uncanny Tales to make extra money, and asked if Wollheim knew where he might be able to obtain stories at a low word-rate. Since
Stirring and
Cosmic had never been distributed in Canada, Wollheim was able to offer him Canadian rights to the stories in those magazines, and Colby agreed to pay a quarter of a cent per word, a low rate compared to most American magazines. The sixth issue saw a story by Wollheim appear, and in the seventh issue there were three by Wollheim and one by
Robert W. Lowndes. In total, 37 stories from
Uncanny Tales have been identified as reprints from either
Stirring or
Cosmic. Canadian writers continued to appear in the magazine, including
C. V. Tench, who had sold a story to the first issue of
Astounding Stories in January 1930. The stories of Canadian origin were generally unmemorable, according to science fiction historians
Mike Ashley and
Grant Thiessen, and in some cases the stories may have been plagiarized or rewritten versions of other works. == Bibliographic details ==
