Henry Jekyll was a well respected member of London society. He was a medical doctorand scientist. He theorized that in each man there was a good side and an evil side which could be separated into two. In doing so, the evil side could be controlled and the good side could live without worry. In his experiments, he used himself as the subject to test his hypothesis. His evil side, Mr. Hyde, escaped into London, and terrorized many people and even killed a man. Jekyll, aware of Hyde's actions, decided to stop his experiments because of the suffering he had caused.
