The short answer: Arthur Conan Doyle studied medicine in Edinburgh under the surgeon Joseph Bell, who made diagnoses by noticing small details in a patient's clothing, gait and face. According to Fitzharris, Conan Doyle himself named Bell as the model for Sherlock Holmes in newspaper interviews and letters. A new book by medical historian Lindsey Fitzharris, "Sleuth-Hound", tells how Bell helped the Scottish police with investigations together with police surgeon Henry Littlejohn. Below: what is known from the participants' own words, and what sounds like legend.

Where the news comes from

On 16 October 2026 Smithsonian Magazine published an excerpt from Lindsey Fitzharris's book "Sleuth-Hound: The Case of the Real Sherlock Holmes" (Farrar, Straus and Giroux, 2026). Fitzharris is a medical historian with a doctorate from Oxford. I read only this excerpt, not the whole book.

Who Joseph Bell was

Bell was a senior surgeon at the Royal Infirmary of Edinburgh and taught students. According to Fitzharris, he turned the examination of patients in the hospital amphitheatre into a performance: he looked at a person's clothing, manner and features and drew conclusions from these observations.

One of the cases the students passed around: a young doctor decided that a limping patient had a disease of the hip joint. Bell objected that the shoes had slits cut with a knife where the shoe presses hardest on the foot, so the man had corns. He then announced that this was a case of chronic alcoholism: according to him, the red nose, puffy face, bloodshot eyes and trembling hands showed it. The ending of the story matters: as it is told, Bell told the students that such deductions must be confirmed by concrete evidence, and pointed to the neck of a whisky bottle sticking out of the patient's pocket.

Bell's daughter recalled that on trains he would entertain his children by telling them where fellow passengers were from and where they were going, what they did for a living and what their habits were, without ever speaking to them. "When he verified his observations, we thought him a magician," she recalled.

The link with Holmes

Conan Doyle began studying under Bell at the University of Edinburgh in 1878. He later wrote that it is not enough to say a man is clever: the reader wants to see examples, "such examples as Bell gave us every day in the wards". According to Fitzharris, in 1892 Conan Doyle revealed that Bell was the model for Holmes.

Bell, according to Fitzharris, downplayed his role in the investigations. In an 1893 interview with the Pall Mall Gazette, he said the only credit he could take was that he had impressed over and over again on all his students, Conan Doyle among them, the vast importance of little distinctions and the endless significance of trifles.

Holmes first appeared in print in late 1887. According to the figures Smithsonian cites, he has been depicted in film and television more than 250 times, and Guinness World Records named him the most-portrayed literary human character.

Bell and the police

According to Fitzharris, from the early 1870s Bell worked in earnest with his friend and colleague Henry Duncan Littlejohn, Edinburgh's police surgeon, whom she calls a pioneer of fingerprinting and crime-scene photography. By 1892, she writes, they had been working together for more than 20 years on high-profile murder cases.

The excerpt names three cases. The first: the poisoner Eugène Marie Chantrelle (the murder of Elizabeth Chantrelle in 1878). The second: the trial of Jessie King, accused of murdering two children placed in her care (Bell gave evidence at this trial). The third: the mysterious death of a young aristocrat on the Ardlamont estate. One more detail: Bell followed the killings in London's Whitechapel from Edinburgh in 1888 and claimed to have identified the murderer, but whom he named is unknown.

What here is confirmed and what is not

This is my own breakdown, not words from the source.

  1. The participants' quotes. Bell's words about the "significance of the trifles" from the 1893 interview and Conan Doyle's line about Bell's examples in the wards are given in the excerpt as quotations. I did not open the original sources myself.
  2. The author's summary. That Conan Doyle named Bell as the prototype in interviews and letters is summarised in the excerpt, not quoted.
  3. Anecdotes. The case of the corns and the bottle, according to Fitzharris, comes from anecdotes that students passed among themselves. It is a good illustration of the method, but not a record.
  4. The book author's opinion. That without Bell Holmes would most likely not exist, and that Bell is largely absent from histories of forensics and criminology, are Fitzharris's assessments.
  5. Unknown. Whom Bell suspected in the Whitechapel case and how large his contribution was to each of the investigations named: he himself, judging by the 1893 interview, downplayed his role.

How to read news like this. A book excerpt is not a scientific paper: the author chooses vivid scenes, and in this excerpt some of them rest on recollections, such as the daughter's account and the student anecdotes. To check a particular episode, open the link that the excerpt itself gives: in the Smithsonian text, for example, the 1893 interview comes with a link. Check whether the quotation matches. If the original source does not open or there is no link, treat the episode as the book author's retelling and do not present it as an established fact.

Summary

Joseph Bell, an Edinburgh surgeon, taught students, Conan Doyle among them, to notice small details, and, according to Fitzharris, Conan Doyle named him as the model for Holmes. According to Lindsey Fitzharris's new book, Bell helped the police for more than 20 years together with Henry Littlejohn. The details of individual cases and the extent of Bell's part in them are worth checking against the book itself and its references.
