followed by many more, first in the U.S. (where they are known as "scion societies"—offshoots—of the Baker Street Irregulars) and then in England and Denmark. There are at least 250 societies worldwide, including Australia, Canada (such as The Bootmakers of Toronto), India, and Japan. Fans tend to be called "Holmesians" in the U.K. and "Sherlockians" in the U.S., though recently "Sherlockian" has also come to refer to fans of the Benedict Cumberbatch-led BBC series regardless of location. Legacy The detective story Although Holmes is not the original fictional detective, his name has become synonymous with the role. Doyle's Sherlock Holmes stories introduced multiple literary devices that have become major conventions in detective fiction, such as the companion character who is not as clever as the detective and has solutions explained to him (thus informing the reader as well), as with Dr. Watson in the Holmes stories. Other conventions introduced by Doyle include the arch-criminal who is too clever for the official police to defeat, like Holmes's adversary Professor Moriarty, and the use of forensic science to solve cases. The Sherlock Holmes stories established crime fiction as a respectable genre popular with readers of all backgrounds, and Doyle's success inspired many contemporary detective stories. Holmes influenced the creation of other "eccentric gentleman detective" characters, like Agatha Christie's fictional detective Hercule Poirot, introduced in 1920. Holmes also inspired a number of anti-hero characters "almost as an antidote to the masterful detective", such as the gentleman thief characters A. J. Raffles (created by E. W. Hornung in 1898) and Arsène Lupin (created by Maurice Leblanc in 1905). "Elementary, my dear Watson" The phrase "Elementary, my dear Watson" has become one of the most quoted and iconic aspects of the character. However, although Holmes often observes that his conclusions are "elementary", and occasionally calls Watson "my dear Watson", the phrase "Elementary, my dear Watson" is never uttered in any of the sixty stories by Conan Doyle. One of the nearest approximations of the phrase appears in "The Adventure of the Crooked Man" (1893) when Holmes explains a deduction: Excellent!' I cried. 'Elementary,' said he." William Gillette is widely considered to have originated the phrase with the formulation, "Oh, this is elementary, my dear fellow", allegedly in his 1899 play Sherlock Holmes. However, the script was revised numerous times over the course of some three decades of revivals and publications, and the phrase is present
