Sir Arthur Conan Doyle was born in Edinburgh, Scotland, and from 1876 to 1881, studied medicine at the University of Edinburgh Medical School. Holmes was partially modelled on Doyle's former university teacher Joseph Bell. In 1892, in a letter to Bell, Doyle wrote, "It is most certainly to you that I owe Sherlock Holmes ... round the centre of deduction and inference and observation which I have heard you inculcate I have tried to build up a man" and in his 1924 autobiography, he remarked, "It is no wonder that after the study of such a character [viz., Bell] I used and amplified his methods when in later life I tried to build up a scientific detective who solved cases on his own merits and not through the folly of the criminal."
