Arthur Conan Doyle created the character of Sherlock Holmes. Holmes was inspired by Doyle's professor Dr. Joseph Bell, who had an amazing ability to deduce things about patients. Doyle struggled as a doctor and turned to writing. His Sherlock Holmes stories became very popular due to their ability to solve crimes at a time when London faced high crime rates, corruption, and serial killers like Jack the Ripper went uncaught. Doyle's stories gave people hope during a dark time.
