The Black Cat was an American fiction magazine launched in 1895 by Herman Umbstaetter, initially published in Boston, Massachusetts. It published only short stories, and had a reputation for originality and for encouraging new writers. Umbstaetter’s editorial approach was unusual in several ways: the cover price was low, at five cents; he paid on merit, not on story length; and he was willing to buy stories by new authors rather than insisting on well-known names. He frequently ran story contests to attract amateur writers. The magazine was immediately successful, and its circulation was boosted by the appearance in an early issue of “The Mysterious Card”, by Cleveland Moffett, which was so popular that two print runs of the issue it appeared in sold out.
