One can achieve somewhat of an understanding of how Sherlock Holmes came to exist by looking at the contributions of three people: Conan Doyle himself, Edgar Allan Poe, and Conan Doyle’s mentor in medical school, Dr. Joseph Bell. First we shall look at Conan Doyle, focusing on those aspects of his life that led to his writing of the Sherlock Holmes stories. Arthur Conan Doyle was born on May 22, 1859, in Edinburgh. His father, Charles Altamont Doyle, was English and his mother, Mary Foley, was Irish. His father had a drinking problem and was consequently less a factor in Conan Doyle’s upbringing than was his mother. Charles would eventually end up in a lunatic asylum (Stashower 1999, 24). Mary Doyle instilled in her son a love of reading (Symons 1979, 37; Miller 2008, 25) that would later lead him to conceive of Sherlock Holmes. Conan Doyle’s extensive reading had a great influence on the Sherlock Holmes stories (Edwards 1993). He was raised a Catholic and attended Jesuit schools at Hodder (1868–1870) and Stonyhurst (1870–1875), which he found to be quite harsh. Compassion and warmth were less favored than “the threat of corporal punishment and ritual humiliation” (Coren 1995, 15). Next he spent a year at Stella Matutina, a Jesuit college in Feldkirch, Austria (Miller 2008, 40). As Conan Doyle’s alcoholic father had little income, wealthy uncles paid for this education. By the end of his Catholic schooling, he is said to have rejected Christianity (Stashower 1999, 49). At the less strict Feldkirch school, his drift away from religion turned toward reason and science (Booth 1997, 60). At this time he also read the writings of Edgar Allan Poe, including his detective stories. So, although Sherlockians debate the “birthplace” of Holmes, a claim can be made that Holmes was conceived in Austria. In 1876, Conan Doyle began his medical studies at the highly respected University of Edinburgh. These years also played a large role in shaping the Holmes stories. One obvious factor was his continued exposure to science.
