“You will not apply my precept, he said, shaking his head. How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth? We know that he did not come through the door, the window, or the chimney. We also know that he could not have been concealed in the room, as there is no concealment possible. When, then, did he come?” -Sherlock Holmes in The Sign of the Four, Ch. 6 (1890)
Through books and television we have been captivated by this flamboyant character as we watch him go from case to case finding and apprehending the criminals of his day, with his trusted sidekick Dr Watson. Then we settle back down satisfied with our adventure into the world of fiction, but the character of Sherlock Holmes is not entirely fiction. He was based on a dazzling medical surgeon who entertained his students with his observational abilities.
He was based on the work of Dr Joseph Bell. When we think of forensics science, DNA evidence, fingerprint analysis and blood spatter patterns spring to mind, and while accurate these are the modern day advancements we have seen within forensics in most recent years.
There is a great deal of history behind these technological developments encompassing much more than test tubes, computer aided modelling and scientists in lab coats.
The Birth of Forensics Science – Dr Joseph Bell
Dr Joseph Bell was a medical scholar and surgeon, lecturing at the University of Edinburgh Medical School in the late 1800’s. He is the man who the birth of forensics science is attributed to, using scientific observation techniques in his work and bringing this aspect into crime investigations for the first time.
It is reported that Dr Bell was involved in a number of criminal investigations, helping police by using his insights through observation to give them information about the victim of crime, a crime scene and who may be responsible.
Some reports suggest he was involved in the investigation hunting for Jack the Ripper in 1888 in London. Rumour has it that Dr Joseph Bell examined the crime scenes of the Ripper murders and used his observations to come up with the name of a suspect. Sealed in an envelope and sent down from Scotland to London, nothing more is reported of this suspect. However, just afterwards the Jack the Ripper murders ceased never to be restarted again.
The technical definition of forensics science is the gathering of information and data about past events that can then be presented in a court of law within a criminal investigation. In early criminal investigations, a confession from a perpetrator or an eyewitness report were the tools relied upon and required for any chance of solving a crime.
Dr Joseph Bell was obsessed with observation and how through closely observing the details of a person’s medical symptoms, an accurate medical diagnosis could be made. He also felt this technique was applicable in crime investigation in order to discover facts and information about a crime which many others may have missed.
His detailed knowledge of the human body, the effects of manual labour, disease and of human behaviour allowed him to quickly spot signs which could inform him of an individual’s occupation and lifestyle. He was by all accounts a slightly eccentric individual who enjoyed his work immensely. He was a lecturer of great acclaim, exciting his students with tricks and demonstrations to test their concentration and highlight the subtle signs they had overlooked.
This notion of observation, key features, behaviours and traits that could tell us something about an individual was a more analytic approach based in scientific theory. Bell’s work opened people’s eyes and minds to what is possible. By applying scientific principles to crime scenes a great deal of valid information could be gained, moving a criminal investigation towards cracking a case and apprehending a suspect.
The introduction of such forensic methodology meant that evidence out-with testimony of victims or witnesses could now be obtained in order to support or refute such verbal reports. Furthermore, fingerprints, blood, hair samples and even the murder weapon could hold vital clues as to what had happened to whom, when and at who’s hand.
If the idea of close observation and picking up on fine detail and subtle signs had not been demonstrated by Dr Joseph Bell, it is questionable where forensic science may stand today.
The Phenomenon of Sherlock Holmes
Dr Joseph Bell’s popularity and the idea of using scientific forensic techniques in crime solving was further progressed through the fictional works and the character of Sherlock Holmes. The writer of the hugely popular Sherlock Holmes fictional books, Arthur Conan Doyle was Dr Bell’s student and worked with him for a number of years, witnessing his behaviour and his methods.
He claimed the developing character of Sherlock Holmes was based in part on Dr Bell and his techniques of observation. The Sherlock Holmes series published between 1887 and 1927, while works of fiction, encouraged interest and intrigue into this type of investigation.
Early Forensics – The Flies and the Sickle
Before the work of Dr Joesph Bell, the earliest recorded case of application of forensic science in solving a crime was in 1247 in China. Police were investigating the stabbing of a victim in the street. By closely examining the stab wounds and comparing such patterns to various weapons, the type of murder weapon, in this case a sickle, was able to be determined.
Furthermore, the coroner in this case used observational techniques at the crime scene to speculate on possible motives for the crime. No personal items were removed, ruling out the idea that robbery was a motive.
Lining up his suspects with their sickles at their feet, the coroner searched in vain for blood stains. Unable to see any with the naked eye he waited and soon enough a number of flies homed in on one particular sickle, attracted by the minute blood specks that remained on the weapon. This act highlighted to the by now rather bemused coroner that this was indeed his murder weapon held by the perpetrator himself, which was closely followed by a full confession to the crime.
The findings and solution in this case were reported in a handbook for coroners “The Washing Away of Wrongs” in 1247 and was used as a guidebook for coroners across Europe for many years.
The Development of Forensics Science
In early 16th century as increasing incidents of death by foul play and violent means were being seen, an interest in the cause of death began to emerge. By applying medical knowledge on body structure, organs and functions and an understanding of how the body reacts to trauma, a deeper understanding of how such incidents can result in death and what may or may not have been involved began to emerge.
When trying to solve a crime in this era, establishing a motive and a clear link between the victim of crime and the person responsible was the main objective.
In the days before computer technology and data analysis for testing materials and fluids, police investigators had to rely on what they could observe from the crime scene and what reasoning they could find for a crime to be committed.
By the 18th century, increasingly logic was being applied and used pro actively within criminal investigations. Matching measurements and observational information found at crime scenes with outside information.
For example, what industries were in the area, which profession wore the type of footwear which may leave such impressions in the earth, the whereabouts of individuals and the times of day crimes occurred all started to be incorporated.
A logical line of thinking created new leads in a case, areas to follow up and investigate and filling in the gaps. Asking such logical questions and actively seeking the answers was leading police to their suspects and ultimately solving crimes.
As the years rolled on scientific discoveries and methodology began to emerge. Each one following from another adding to the repertoire of tools available to crime investigators. Fingerprint analysis for example was hailed a breakthrough when in 1880 Henry Faulds, a Scottish scientist, realised that each individual had a distinctive set of fingerprints belonging only to them and these could be used as a basis for identification. In that same year, he used his methodology to eliminate an innocent suspect from a murder case due to fingerprint evidence.
The Bertillon System of Identification
In 1879 in Paris, police officer Alphonse Bertillon is credited with being the first person to examine the human body carefully in crime scenes, taking measurements and notes, a practice termed anthropometry.
By comparing the measurements of different body parts for different individuals it was believed this could be used as a method of identification and create a detailed description of a person and their features. Now commonly referred to as the Bertillon System, it was one of the first techniques to be accepted as a scientifically based method of criminal investigation.
“Every measurement slowly reveals the workings of the criminal. Careful observation and patience will reveal the truth” – Alphonse Bertillon
An excellent article from the US National Library of Medicine shows how the Bertillon system was used to identify offenders and in murder scenes.
Officers began to search through previous criminal records adding an individual’s measurements to make future identification easier. Detailed photographs of the head and face were introduced and included in a suspects records.
The Bertillon System was introduced in the United States in 1887 and quickly became the preferred method for criminal identification, adopted by Europe and widely used until the early 1900’s, when fingerprint evidence and the discoveries of Henry Faulds really began gaining steam.
As time has gone on, more advanced techniques replaced the Bertillon methodology however it’s principles are still in place, profile photographs and standard notes about appearance and body shape and size and now routine within a suspects details.
In 1896 the first fingerprint identification system was introduced within Europe lead by Sir Edward Richard Henry and criminal investigations started to include such forensic techniques with fingerprinting being introduced in Scotland Yard in 1902.
The Future of Forensics
Today, modern forensics science dominates police investigations and criminal proceedings. The advancement of technology such as computers has greatly enhanced the capabilities of science.
The disciplines within forensics science have expanded rapidly in recent years now including anthropology, digital and multimedia sciences, pathology and biology, criminalists, and psychiatry and behavioural sciences. A good detective is one who can find the missing links in an investigation using the small details and logical thinking and all of these various scientific resources to solve the puzzle. As science continues to progress, further discoveries will undoubtedly be made adding to the options available within criminal investigation.
The influence of Dr Joseph Bell in advancing forensics science should not be underestimated. He was a man with vision and intense interest in his field, inspiring hundreds of students and in playing a role in the resulting Sherlock Holmes phenomenon. Dr Bell died in 1911 and his grave can be found at the Dean Cemetery in Edinburgh.
