John Ulrich Giesy (August 6, 1877 – September 8, 1947) was an American physician, novelist and author. He was one of the early writers in the Sword and Planet genre, with his Jason Croft series.[1] He collaborated with Junius B. Smith on many of his stories.
Robert Weinberg's website described the series of stories starring Jason Croft as "[o]ne of the most popular scientific romance trilogies published in All-Story Weekly magazine of the first quarter of the 20th century."[4] Giesy also wrote for other pulp magazines such as Argosy, Adventure and Weird Tales. Giesy's 1915 novel All For His Country is a story of a future invasion of the US by the Japanese.[5] Because All For His Country depicts Japanese-Americans living in California helping the invasion, some critics have cited it as an example of the anti-Japanese racism that ultimately resulted in the Internment of Japanese Americans after Pearl Harbor.[6]
Giesy lived in Salt Lake City where he met Junius B. Smith, with whom he co-authored a large number of stories, including those featuring the occult detective Semi-Dual.
