January 5,1886: "The Strange Case of Dr Jekyll and Mr Hyde," by Robert Louis Stevenson, is published by Longmans, Green & Co.
“Stevenson had long been fascinated with split personalities but couldn’t figure out how to write about them. Then one night he had a dream about Dr. Jekyll and Mr. Hyde. “In the small hours of one morning ... I was awakened by cries of horror from Louis," his wife Fanny said. "Thinking he had a nightmare, I awakened him. He said angrily: 'Why did you wake me? I was dreaming a fine bogey tale.'" (via MentalFloss)
