Jason, Son of Jason

John Ulrich Giesy was an American doctor, novelist, and author. He was an early writer in the Sword and Planet genre, with his Jason Croft series. He worked with Junius B. Smith on several of his stories. According to Robert Weinberg's website, the series of stories featuring Jason Croft was one of the most popular scientific romance trilogies published in All-Story Weekly magazine during the first quarter of the twentieth century. Giesy also contributed to other pulp magazines, including Argosy, Adventure, and Weird Tales. All For His Country, Giesy's 1915 novel, is about a future Japanese invasion of the United States. Because All For His Country depicts Japanese-Americans living in California assisting in the invasion, some critics have characterized it as an example of anti-Japanese prejudice that led to the internment of Japanese Americans following Pearl Harbor. Giesy lived in Salt Lake City, where he met Junius B. Smith, with whom he co-wrote numerous novels, notably those featuring the occult investigator Semi-Dual.
