Fingerprinting has been used by law enforcement for identification, with its history tracing back thousands of years to ancient civilizations in China, Babylon, and Japan. These cultures used fingerprints in business contracts as a form of unforgeable identification.
In Europe, scientists like Dr. Nehemiah Grew and Marcelo Malpighi began studying the epidermal layer and distinct ridge patterns of human skin. Malpighi, using an early microscope, observed fingerprints in detail, discovering their role in increasing friction for gripping objects, although he did not recognize their individual uniqueness.
During the British colonization of India in 1858, Sir William James Herschel started using handprints and later fingerprints on contracts and official documents to prevent fraud. He observed that fingerprints remained constant throughout a person's life, concluding their permanence and uniqueness.
Henry Faulds, a pioneer in dactyloscopy, studied fingerprints extensively in Japan and advocated for their use in identification. His work was passed to Sir Francis Galton, who published 'Fingerprints' in 1892, establishing that fingerprints are formed before birth and persist throughout life, and identifying specific details now known as Galton details.
In 1892, detective Eduardo Alvarez in Buenos Aires, Argentina, used a bloody thumbprint found at a crime scene to identify and convict a mother who had murdered her two children. This marked the first recorded crime solved using fingerprint identification.
Within a decade, fingerprinting was adopted globally for forensic analysis. The US established its fingerprinting system in 1902, maintained by the FBI with millions of prints, including those for various licenses. Despite being considered strong evidence, fingerprints have flaws, as they rely on examiner interpretation of often partial or smudged prints, leading to potential inaccuracies and biases.
