Alphonse Bertillon (April 24, 1853—February 13, 1914) was a French law enforcement officer and biometrics researcher who created anthropometry, an identification system based on physical measurements. Anthropometry was the first scientific system police used to identify criminals. Until this time, criminals could only be identified based on eyewitness accounts, which are known to be unreliable. The method was eventually supplanted by fingerprinting, but "his other contributions like the mug shot and the systematisation of crime-scene photography remain in place to this day."
Alphonse Bertillon was born April 24 1853 in Paris.

Alphonse Bertillon (April 24, 1853—February 13, 1914) was a French law enforcement officer and biometrics researcher who created anthropometry, an identification system based on physical measurements. Anthropometry was the first scientific system police used to identify criminals. Until this time, criminals could only be identified based on eyewitness accounts, which are known to be unreliable. The method was eventually supplanted by fingerprinting, but "his other contributions like the mug shot and the systematisation of crime-scene photography remain in place to this day."
Alphonse Bertillon was born April 24 1853 in Paris. He was a son of statistician Louis-Adolphe Bertillon and younger brother of the statistician and demographer Jacques Bertillon.
After being expelled from the Imperial Lycée of Versaille, Bertillon drifted through a number of jobs in England and France, before being conscripted into the French army in 1875. Several years later, Bertillon was discharged from the army with no real higher education, so his father arranged for his employment in a low-level clerical job at the Prefecture of Police in Paris. Thus, Bertillon began his police career on March 15, 1879 as a department copyist.
Being an orderly man, he was dissatisfied with the ad hoc methods used to identify captured criminals who had been arrested before. This motivated his invention of anthropometrics. Bertillon's road to fame was a protracted and hard one as he was forced to do his measurements in his spare-time. He used the famous La Santé Prison in Paris for his activities facing jeers from the prison inmates as well as police officers.
In 1882 Bertillon decided to show a criminal identification system known as anthropometry but later also known as Bertillonage in honor of its creator. In this system the person was identified by body measurement of the head and body, individual markings - tattoos, scars - and personality characteristics. The measurements were made into a formula that would apply only on one person and would not change. He used it in 1884 to identify 241 multiple offenders, and the system was quickly adopted widely by American and British police forces. Part of its benefit was that by arranging the records carefully, it would be very easy to sift through a large number of records quickly given a few measurements from the person to be identified. While it might not always give an exact match, it would allow one to narrow the pool of possible people and then to compare the person with a photograph.
The system was eventually found to be flawed, however, because often two different officers made their measurements in slightly different ways and would not obtain the same numbers. Measurements could also change as the criminal aged. It also could identify two individuals as the same person, unlike fingerprinting. Allegedly, in 1903, a man named Will West, arrested in Kansas, was found to be a previously arrested man with anthropometrics, but fingerprinting -- first used to secure a conviction in the modern era in the case of an Argentine murder of 1897 -- seemed the only way to differentiate them.
The system was widely used by French police and in other European countries. In France it was popular enough that it was widely used even after the advent of fingerprinting. One audacious member of the Bonnot gang sent police his fingerprints because he knew they did not have them, just his physical measurements.
Bertillon was a witness for the prosecution in the Dreyfus Affair in 1894 and again in 1899. He testified as a handwriting expert and claimed that Alfred Dreyfus had written the incriminating documents. However, he was not a handwriting expert, and his convoluted and flawed evidence was a contributing factor in no small way to one of the most infamous miscarriages of justice - the condemnation of an innocent man - Alfred Dreyfus - to life imprisonment on Devil's Island. Bertillon was by many accounts regarded as extremely eccentric. According to Maurice Paleologue, who observed him at the second court-martial, Bertillon was "certainly not in full possession of his faculties". Paleologue goes on to describe Bertillon's argument as "a long tissue of absurdities", and writes of "his moonstruck eyes, his sepulchral voice, the saturnine magnetism" which made him feel that he was "in the presence of a necromancer". See: My Secret Diary of the Dreyfus Case by Maurice Paleologue. Secker and Warburg 1957 (page 197)
Bertillon also standardized the criminal mug shot and the evidence picture. He developed "metric photography" that he intended to use to reconstruct the dimension of a particular space and the placement of objects in it. Crime scene pictures were taken before the scene was disturbed in any way. He used mats printed with metric frames that were mounted along the side of the photographs. Photographs pictured front and side views of a particular object.
Bertillon also created many other forensics techniques, including Forensic document examination, the use of galvanoplastic compounds to preserve footprints, ballistics, and the dynamometer, used to determine the degree of force used in breaking and entering.
Alphonse Bertillon died February 13 1914 in Münsterlingen, Switzerland.
Bertillon is referenced in the Sherlock Holmes storyThe Hound of the Baskervilles in which one of Holmes's clients refers to Holmes as the "second highest expert in Europe" after Bertillon. Also, in The Naval Treaty, speaking of the Bertillon system of measurements Holmes himself "...expressed his enthusiastic admiration of the French savant". In the Arsène Lupin story The Escape of Arsène Lupin by Maurice Leblanc, Lupin escapes by exploiting the same flaws in anthropometry that led to its eventual disuse.
Bertillon is also referenced in the Caleb Carr novel The Alienist. The Isaacson brothers, who are detectives, mention that they are trained in Bertillon system.
