The Story of an Hour is a short story written by Kate Chopin on April 19, 1894, and originally published in Vogue on December 6, 1894 as "The Dream of an Hour". It was first reprinted in St. Louis Life on January 5, 1895 as "The Story of an Hour."
The title of the short story refers to the time elapsed between the moments at which the protagonist, Louise Mallard, hears that her husband is dead and discovers that he is alive after all. The Story of an Hour was considered controversial during the 1890s because it deals with a female protagonist who feels liberated by the news of her husband's death. In Unveiling Kate Chopin, Emily Toth argues that Chopin "had to have her heroine die" in order to make the story publishable.
