Notice: We are transforming our Forensic Science Timeline into a more detailed and comprehensive journey through the eras of forensic science. Each era, from ancient forensic methods to the latest technological breakthroughs, will have its own post with in-depth insights into key developments.
We will be adding new, comprehensive posts for each forensic milestone every week, so be sure to check back as we continue to explore the fascinating history and future advancements of forensic science. You’ll be able to delve deeper into the techniques, innovations, and cases that have shaped this field!
B.C.E: Use of Fingerprints by Prehistoric Humans
Evidence of fingerprints in early paintings and rock carvings of prehistoric humans. Writing of a hand with ridge patterns is discovered in Nova Scotia. In ancient Babylon, fingerprints are used on clay tablets for business transactions.

2200 BC: The earliest documented code of Law
The earliest documented code of law, promulgated by Hammurabi, king of Babylon, around 2200 BC, contained laws governing the practice of medicine.

460-355 BC: Lethality of wounds
In Greece, Hippocrates showed how medicine could influence legal matters by discussing the lethality of wounds.

384-327 BC: Curious Aristotle
Aristotle, a student of Plato and tutor of Alexander the Great, greatly expounds on the study of science and scientific observations, which would later influence forensics and crime investigations, among other things.

339 BC: Use of Poison
Socrates was executed by poisoning with hemlock. The early Greeks were familiar with poisons, and there are references to Ulysses and Hercules anointing their arrows with the serpent’s venom.

300 BC: First Dissections
Herophilus, a Greek scientist, is credited as the first to perform dissections in Alexandria.

287-212 BC: Eureka
The “Eureka” legend told of Archimedes, where the philosopher proved that a crown was not solid gold by comparing measurements of its displacement of water and its weight. It is a direct forerunner of modern forensic engineering techniques. The case marked a critical point when quantitative methods became vital and established the concepts of density, buoyancy, force, and equilibrium.

230 BC: First Lie Detection Technique
ERASISTRATUS, an ancient Greek physician, observed that his patients’ pulse rates increased when they told him lies. This is supposed to be the first lie detection test.

44 BC: Death of an emperor
After Julius Caesar was assassinated in ancient Rome, a physician performed an autopsy and determined that only one was fatal of the 23 wounds found on the body.

49 AD: First recorded account of Forensic Dentistry
The first recorded example of forensic dentistry may be the account of Agrippina, the Roman emperor Nero’s mother. She sent for the head of her enemy Lollia Paulina to verify her death. While the face was distorted beyond recognition, Agrippina could recognize a distinctively colored front tooth that she had previously noticed in Lollia’s mouth.

50-70 AD: Foundation of Forensic Toxicology
Pedanius Dioscorides, a Greek physician, living in Rome, categorizes various plants, their medicinal effects, and their poisoning symptoms. De Materia Medica’s work is considered the foundation of forensic Toxicology.
53-96 AD: First use of Fingerprint Science in Exoneration
A Roman orator and an attorney in the Roman courts, Quintilian, uses known science to prove bloody handprints did not belong to the accused murderer and showed that bloody palm prints were meant to frame a blind man of his mother’s murder.
400s: Who determines the cause of Death
German and Slavic societies made a law that medical experts must be the ones to determine the cause of death in crimes.
600s: Recognized the Expert witness’s particular position
In the sixth century, Emperor Justinian recognized the special position of the expert witness when he declared that physicians were not ordinary witnesses but rather persons who gave judgments rather than testimony.
700s: Fingerprint used for Identification
700s Chinese used fingerprints to establish documents and clay sculpture identity without a formal classification system.
800s: The “inheritance powder”
Arsenic oxide is first produced commercially due to iron and lead mining refining ore. It will become the poison of choice for many over the succeeding centuries – especially Black Widows and Bluebeards, often called “inheritance powder.”
