Both Tuck and the Encyclopedia of Science Fiction consider Bruce Wallis to merely be an agent for Geo C. Wallis. Bleiler, in <i>Science-Fiction: The Gernsback Years</i>, states that this seems unlikely. Bleiler further states that Bruce Wallis lived in British Columbia in the early 1930s, and had claimed to be a seaman on sailing ships. In any case, he was a cousin to George Wallis.
