The Original CSI: Crime scene photos from the early 1900s
The French detective and biometrics researcher Alphonse Bertillon was the father of modern crime scene investigation. Among his major contributions were the mugshot and the crime scene photograph.
Before Bertillon pioneered the use of the mugshot criminals were identified by verbal description and artist sketches—which were not always reliable as eyewitness often gave confusing and contradictory descriptions. The mugshot obviously made it easier for police to identify and apprehend criminals and to disseminate posters of the most wanted across country.
Bertillon was the first to recognize the importance of using photography to document a crime scene—the position of the body, the murder weapon, the footprints or personal artefacts left behind, the disarray of the scene. While some at first doubted the relevance of photographing murder victims—considering it ghoulish and highly disrespectful to the deceased—it became quickly apparent how such photographs helped solve innumerable murders.
Bertillon also devised a system of anthropometry by which criminals could be identified. The system, called "Bertillonage," classified criminals by identifiable physical characteristics-eyes, length of nose, shape of ear, measurements of head, etc. From the late 1800s until around the end of the First World War Bertillonage was the main system for identifying criminals as used across Europe and America. It was eventually replaced by fingerprinting.
His success as a detective led Bertillon to be described by Sir Arthur Conan Doyle as the greatest detective in Europe—rivalling his very own creation Sherlock Holmes who was only the "second highest expert in Europe."
There is an oft-quoted story that Bertillonage was discredited by the strange case of two men Will West and William West in 1903. The story goes that when Will West was arrested and sentenced to Leavenworth prison, his anthropometric measurements matched another prisoner who was also (quite unbelievably) called William West. Yet, according to Bertillon's methodology both men were the very same person—which was of course impossible.
Though it was claimed their measurements were identical—it is probably more correct to say these figures conformed within certain ratios which were similar but not exactly the same. The two men were later identified by fingerprinting—and it was this that gave lie to the claim that the confusion over Will West and William West led to the abandonment of the Bertillonage system. However, it should be pointed out that Bertillonage was used up as late as 1918 in America and Canada and around the time in Europe. What probably discredited this system of anthropometry more than anything else was its adoption by the Nazis prior to the Second World War as a means to identify non-Aryans.
The following photographs were taken by Alphonse Bertillon (or are credited to him) and depict some of the murder scenes he encountered during his work as a detective. They are among the very earliest crime scene photographs ever taken.
