behaviour sometimes follow those of Lecoq. Doyle has his main characters discuss these literary antecedents near the beginning of A Study in Scarlet, which is set soon after Watson is first introduced to Holmes. Watson attempts to compliment Holmes by comparing him to Dupin, to which Holmes replies that he found Dupin to be "a very inferior fellow" and Lecoq to be "a miserable bungler". Conan Doyle repeatedly said that Holmes was inspired by the real-life figure of Joseph Bell, a surgeon at the Royal Infirmary of Edinburgh, whom Conan Doyle met in 1877 and had worked for as a clerk. Like Holmes, Bell was noted for drawing broad conclusions from minute observations. However, he later wrote to Conan Doyle: "You are yourself Sherlock Holmes and well you know it". Sir Henry Littlejohn, Chair of Medical Jurisprudence at the University of Edinburgh Medical School, is also cited as an inspiration for Holmes. Littlejohn, who was also Police Surgeon and Medical Officer of Health in Edinburgh, provided Conan Doyle with a link between medical investigation and the detection of crime. Other possible inspirations have been proposed, though never acknowledged by Doyle, such as Maximilien Heller, by French author Henry Cauvain. In this 1871 novel (sixteen years before the first appearance of Sherlock Holmes), Henry Cauvain imagined a depressed, anti-social, opium-smoking polymath detective, operating in Paris. It is not known if Conan Doyle read the novel, but he was fluent in French. Similarly, Michael Harrison suggested that a German self-styled "consulting detective" named Walter Scherer may have been the model for Holmes. Fictional character biography Family and early life Details of Sherlock Holmes's life in Conan Doyle's stories are scarce and often vague. Nevertheless, mentions of his early life and extended family paint a loose biographical picture of the detective. A statement of Holmes's age in "His Last Bow" places his year of birth at 1854; the story, set in August 1914, describes him as sixty years of age. His parents are not mentioned, although Holmes mentions that his "ancestors" were "country squires". In "The Adventure of the Greek Interpreter", he claims that his grandmother was sister to the French artist Vernet, without clarifying whether this was Claude Joseph, Carle, or Horace Vernet. Holmes's brother Mycroft, seven years his senior, is a government official. Mycroft has a unique civil service position as a kind of human database for all aspects of government
