Joseph Bell, who taught analytics and deductions to Doyle, it is believed that Sherlock Holmes was based on Bell.

Bell was a great-grandson of Benjamin Bell, a forensic surgeon. In his instruction, Joseph Bell emphasized the importance of close observation in making a diagnosis. To illustrate this, he would often pick a stranger and, by observing him, deduce his occupation and recent activities. These skills caused him to be considered a pioneer in forensic science (forensic pathology in particular) at a time when science was not yet widely used in criminal investigations.

Bell studied medicine at the University of Edinburgh Medical School and received an MD in 1859. Bell served as personal surgeon to Queen Victoria whenever she visited Scotland. He also published several medical textbooks. Bell was a Fellow of the Royal College of Surgeons of Edinburgh, a Justice of the Peace, and a Deputy Lieutenant.

Bell wrote the book Manual of the Operations of Surgery which was published in 1866.^[2]

Joseph Bell died on 4 October 1911. He was buried at the Dean Cemetery in Edinburgh alongside his wife, Edith Katherine Erskine Murray, and their son Benjamin, and next to his father's and brother's plots. The grave is midway along the north wall of the northern section to the original cemetery.

Inspiration of Sherlock Holme[edit]

Arthur Conan Doyle met Bell in 1877, and served as his clerk at the Edinburgh Royal Infirmary. Doyle later went on to write a series of popular stories featuring the fictional character Sherlock Holmes, who Doyle stated was loosely based on Bell and his observant ways.^[3] Bell was aware of this inspiration and took some pride in it. According to Irving Wallace (in an essay originally in his book The Fabulous Originals but later republished and updated in his collection The Sunday Gentleman) Bell was involved in several police investigations, mostly in Scotland, such as the Ardlamont Mystery of 1893, usually with forensic expert Professor Henry Littlejohn.
