In the Western world, the 17th century saw anatomists like Dr. Henry Faulds, a Scottish physician stationed in Japan, published a letter in the scientific journal "Nature" in 1880, suggesting that fingerprints could be used to identify criminals and proposing a method for classifying these patterns.

Police investigator Juan Vucetich used fingerprints found at a murder scene to identify and convict the victim’s mother, Francisca Rojas, who initially denied involvement before implicating herself. Henry’s method, which categorized prints based on ridge patterns into loops, whorls, and arches, allowed for efficient searching and filing of records.
Early Historical Recognition of Fingerprint Uniqueness Long before the technology existed to analyze these patterns scientifically, various civilizations recognized the practical value of fingerprints. The fundamental principle that these epidermal ridges are unique to each individual and remain unchanged throughout life forms the bedrock of a practice that now underpins criminal investigations, border security, and digital access control across the globe.

Nehemiah Grew and Marcello Malpighi describing the microscopic ridge structures of fingerprints, though they did not yet connect these details to individual identification. The United Kingdom formally adopted fingerprint evidence in 1901, replacing earlier, less reliable methods of identification like Bertillonage, which measured physical body parts.
