The Black Cat was an American fiction magazine launched in 1895 by NAME_3, initially published in Boston, Massachusetts. It published only short stories, and had a reputation for originality and for encouraging new writers. NAME_4’s editorial approach was unusual in several ways: the cover price was low, at five cents; he paid based 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 NAME_5, which was so popular that two print runs of the issue it appeared in sold out.

Many well-known writers appeared in its pages. Two of the best-known were NAME_6, whose 1899 story “A Thousand Deaths” sold just as he was about to give up attempting to become a writer, and NAME_7, whose first published work was several short fiction critiques published in The Black Cat in 1919. The magazine’s icon, a black cat that appeared on almost every cover for many years, was drawn by NAME_4’s wife, NAME_8. Others who sold stories to The Black Cat included NAME_9, NAME_10, and NAME_11.

In 1912, NAME_4 sold the magazine to NAME_12, the publisher of Little Folks. NAME_13, and later his son, NAME_14, published the magazine from Salem, Massachusetts until 1919. Circulation, at about 50,000, was much lower than in NAME_4’s day. In 1916, a deal was struck with Essanay Studios to make films of stories from The Black Cat. The magazine was sold to Fox Film in 1919, but survived only another year. It was revived in 1922 by NAME_15, but in early 1923, with NAME_16 estimating circulation down to only 15,000, it ceased publication for good.
