Robert Louis Stevenson made literary history with his novel "Strange Case of Dr. Jekyll and Mr. Hyde." This story of the dual personality being personified during a medical experiment has been told and re-told in adaptations since it was first published in 1886. The novel became so popular that the phrase "Jekyll and Hyde" has come to mean someone whose behavior changes based on the situation they're in.

On Jekyll and Hyde Behavior
"You start a question, and it's like starting a stone.

No, sir, I make it a rule of mine: the more it looks like Queer Street, the less I ask."
