"Half-Breed" is a science fiction short story by American writer Isaac Asimov. It was first published in the February 1940 issue of Astonishing Stories and reprinted in the 1972 collection The Early Asimov. It was the fifteenth story written by Asimov, and the fourth to be published. At 9000 words, it was his longest published story to date. "Half-Breed" was written in June 1939, and submitted to (and subsequently rejected by) Amazing Stories and Astounding Science Fiction before being accepted by Frederik Pohl in October for his new magazine Astonishing Stories. Asimov wrote a sequel to the story, titled "Half-Breeds on Venus". Source: Wikipedia (en)
