March 11, 1818: Frankenstein; or, The Modern Prometheus is published.
The book, by 21-year-old Mary Wollstonecraft Shelley, is frequently called the world’s first science fiction novel. Mary Shelley created the story on a rainy afternoon in 1816 in Geneva, where she was staying with her husband, the poet Percy Bysshe Shelley, and their friend Lord Byron. Byron proposed they each write a gothic ghost story, but only Mary Shelley completed hers. (history.com)
