Stanley Grauman Weinbaum (April 4, 1902 - December 14, 1935) was an American science fiction author. His career in science fiction was short but influential. His first story, "A Martian Odyssey", was published to great (and enduring) acclaim in July 1934, but he would be dead from lung cancer within eighteen months. Weinbaum was born in Louisville, Kentucky and attended school in Milwaukee. He attended the University of Wisconsin, first as a chemical engineering major but later switching to English as his major, but contrary to common belief he did not graduate. On a bet, Weinbaum took an exam for a friend, and was later discovered; he left the university in 1923. He is best known for the groundbreaking science fiction short story, "A Martian Odyssey", which presented a sympathetic but decidedly non-human alien, Tweel. Even more remarkably, this was his first science fiction story (in 1933 he had sold a romantic novel, The Lady Dances, to King Features Syndicate, which serialized the story in its newspapers in early 1934). Isaac Asimov has described "A Martian Odyssey" as "a perfect Campbellian science fiction story, before John W. Campbell.
