“The losses in Kate Chopin’s life had serious impacts on her views and writing. For example, her father’s death inspired her to write ‘The Story of an Hour,’ which was the imagined effect she thought it would have on her mother.” Quote from a biography titled, “Kate Chopin’s Life and Personal Influence,” dated 5-7-2008, by Jasdomin Tolentino, Pace University.
In fact, Kate and her mother were quite alike, they say.
