"Sherlock Holmes is a fictional character created by Arthur Conan Doyle in 1887. He is an English consulting detective living in London at 221b Baker Street. At first Arthur Conan Doyle named the detective as Sherrinford Holmes (not Sherringford as he wrongly mentioned in his auto-biography Memories and Adventures 40 years later) and the biographer Ormond Sacker (see manuscript in A Study in Scarlet). But he changed his mind and renamed them as Sherlock Holmes and John H. Watson.” - The Arthur Conan Doyle Encyclopedia
