Every time a forensic anthropologist reconstructs a face from a skull or matches a bone fragment to a missing person’s DNA profile, they are drawing on nearly two hundred years of scientific trial and error. The field did not begin in a modern crime lab. It began with toxicologists testing poisons, statisticians studying fingerprints, and doctors arguing over how to measure a human skeleton. Here is how those scattered discoveries slowly became the discipline we now call forensic anthropology.

The nineteenth-century foundations
Long before anyone used the phrase forensic anthropology, physical anthropologists and anatomists were occasionally pulled into legal cases simply because they understood the human body better than anyone else in the room. One of the earliest names associated with this shift is Mathiew Orfila, often called the father of modern toxicology, who published his first major work on poison detection in 1813. Four decades later, in 1853, Ludwig Teichmann proposed a microscopic crystal test using hemin crystals to detect the presence of hemoglobin, giving investigators a reliable way to confirm that a stain was, in fact, blood.
Dwight and Galton set the direction
Two other contributions from this era still shape the field today. In 1878, Thomas Dwight wrote an essay titled The Identification of Human Skeleton: A Medico-Legal Study, which is widely credited with laying the groundwork for using skeletal remains in legal contexts. A little over a decade later, in 1892, Francis Galton published his book Fingerprints, demonstrating that every person’s ridge patterns are unique and remain unchanged over a lifetime. Around the same period, researchers such as E. Rollet were building tables to estimate stature from bone length, work that later fed into more refined statistical methods.
The Bertillon system and the science of measurement
In 1879, French criminologist Alphonse Bertillon developed what is considered the first scientific system for identifying repeat offenders, later known as Bertillonage or the Bertillon System. It relied on recording physical details such as hair and eye colour, ear shape, and complexion, along with precise body measurements including height, head length and breadth, arm span, finger length, and foot size.
Bertillon sorted each measurement into small, medium, or large categories, which allowed him to place individuals into 243 distinct classifications. Photographs and notes on scars or tattoos rounded out each profile. The system was genuinely innovative for its time, but it had two serious flaws. It could not be used on children, since bone measurements change with growth, and it suffered from inconsistent results when different police departments took the same measurements on the same person. These weaknesses eventually opened the door for fingerprinting to take over as the primary method of identification.
Blood, genetics, and a new kind of evidence
The next major leap came from biology rather than measurement. In 1901, Karl Landsteiner discovered that human blood could be sorted into distinct groups, a finding that earned him the Nobel Prize and transformed how investigators could link biological evidence to a specific person. Along with the widely used ABO system, five other blood group systems, Rh, MNS, Duffy, Kell, and Kidd, eventually became tools for human identification. The ABO system, tied to a specific genetic locus, became the backbone of early genetic testing in forensic work.
Turning dried stains into evidence
Discovering blood groups was only useful if scientists could actually test old, dried samples. In 1915, Leone Lattes developed a practical method for determining the blood group of dried bloodstains, a technique that helped resolve both marital disputes and criminal investigations. The picture became more detailed in 1940, when Landsteiner and A.S. Wiener described the Rh blood group, adding another layer of precision to genetic identification decades before DNA testing existed.
Rebuilding a face from bone
While chemists and geneticists were working with fluids, other researchers were trying to answer a different question: what did this person actually look like? Facial reconstruction from skeletal remains began with Welcker in 1883 and was advanced by His in 1895, who recorded the first systematic data on facial tissue thickness at different points on the skull. The technique had originated in archaeology, where researchers wanted to reconstruct the appearance of early hominids, before it was adapted for criminal cases.
Age estimation from bone also matured during this period. V. Balthazard published one of the earliest microscopic studies on age-related bone changes in 1911. Decades later, in 1962, Krogman formalised his own facial reconstruction approach in The Human Skeleton in Forensic Medicine, and in 1964, M. Gerasimov applied paleo-anthropological reconstruction methods that had wide influence on the field. The techniques kept evolving with technology: in 2004, Christian Corbet used laser scanning and CT imaging to reconstruct the face of an ancient Egyptian mummy, showing how far the method had come from plaster and clay.
Trace evidence and the birth of the crime lab
Perhaps no single idea has shaped modern forensic science as much as the one formulated by Edmond Locard. In 1910, Locard convinced the Lyon police to give him space to open what became the world’s first police laboratory. His central insight, now known as Locard’s Exchange Principle, holds that any contact between two objects or people leaves behind some trace of that contact, whether it is fibre, dust, or residue. This principle still underlies how crime scenes are processed today.
Around the same period, forensic science began branching into other specialities. Calvin Goddard pioneered forensic ballistics in 1925, introducing the comparison microscope as a way to match bullets and cartridge cases to a specific firearm, a method that remains central to weapons investigations.
The DNA revolution
The single biggest shift in human identification came from genetics. Kary Mullis proposed the Polymerase Chain Reaction, or PCR, a technique that made it possible to amplify tiny amounts of DNA into quantities large enough to analyse. This laid the technical foundation for modern DNA typing. Building on this, Sir Alec Jeffreys developed a DNA fingerprinting method using multi-locus RFLP patterns.
In 1986, Jeffreys’ technique was used for the first time in a criminal investigation in England, where it both cleared an innocent suspect and identified the actual perpetrator in a double murder case, a result described in detail by the US National Library of Medicine’s account of the case. It remains a landmark moment because it was the first time DNA evidence acquitted a wrongly accused person, a use case that continues to matter enormously in modern forensic and human rights work.
Building institutions and national databases
Individual breakthroughs eventually needed institutional support to scale. In the United States, the FBI established a national forensic laboratory under J. Edgar Hoover, extending forensic science services across the country. Technology kept pace with these institutions. In 1991, Walsh Automation Inc. introduced the Integrated Ballistics Identification System (IBIS) to compare shell casings and bullets. In 1998, the FBI launched the National DNA Index System, allowing states to share DNA profiles for interstate investigations. A year later, in 1999, two separate ballistics systems, Drugfire and IBIS, were merged to form the National Integrated Ballistics Identification Network, giving investigators a single, shared database for firearms evidence.
A field that keeps expanding
Forensic anthropology today extends well beyond identifying bodies after a crime. It now overlaps with human rights investigations, international law, taphonomy, exhumation work, and even remote sensing techniques used to locate unmarked graves. Much of the current research in the field is focused on standardising methods and professionalising practice, so that findings hold up not just in a classroom but in a courtroom or a war crimes tribunal.
What is striking when you trace this history is how much of it came from people working in isolation, often decades apart and unaware of how their discoveries would eventually connect. A toxicologist studying poison in the early 1800s and a geneticist running PCR in a lab a century and a half later were, in a sense, building the same toolkit one piece at a time.
What do you think?
What do you think? Which of these milestones do you think had the biggest impact on how modern criminal investigations are conducted: the Bertillon system, blood group typing, or DNA fingerprinting? And do you think forensic anthropology’s expansion into human rights and international law is a natural evolution of the field, or a completely separate discipline that happens to share the same methods?
