Doyle was born on May 22, 1859 at Picardy Place, Edinburgh, as the son of Charles Altamont Doyle, a civil servant in the Edinburgh Office of Works, and Mary (Foley) Doyle. Both of Doyle’s parents were Roman Catholics. His father suffered from epilepsy and alcoholism and was eventually institutionalized. Charles Altamont died in an asylum in 1893. In the same year Doyle decided to finish permanently the adventures of his master detective. Because of financial problems, Doyle’s mother kept a boarding house. Dr. Tsukasa Kobayashi has suspected in an article, that Doyle’s mother had a long affair with Bryan Charles Waller, a lodger and a student of pathology, who had a deep impact to Conan Doyle.
