Question: What author wrote a novel, published in 1961, featuring a minor fictional character named Schiesskopf?
Sentence (from "Nyoka the Jungle Girl"): The character of Nyoka is often described as having been created by Edgar Rice Burroughs; however, although the serial was officially based on Burroughs' story "Jungle Girl" (first appearing in the pulp magazine, "Blue Book", and later published as a novel), there is no character named Nyoka and no Nyoka-like character in the original story.
Relevant evidence: No
