![]() ![]() The information obtained in this way is incorporated in a concise formula, which is known as the individual’s fingerprint classification. His system is still used in most Spanish-speaking countries.įingerprints are classified in a three-way process: by the shapes and contours of individual patterns, by noting the finger positions of the pattern types, and by relative size, determined by counting the ridges in loops and by tracing the ridges in whorls. Juan Vucetich, an employee of the police of the province of Buenos Aires in 1888, devised an original system of fingerprint classification published in book form under the title Dactiloscopía comparada (1904 “Comparative Fingerprinting”). The system was adopted immediately by law-enforcement agencies in the English-speaking countries of the world and is now the most widely used method of fingerprint classification. The Galton-Henry system of fingerprint classification, published in June 1900, was officially introduced at Scotland Yard in 1901 and quickly became the basis for its criminal-identification records. Henry, who later became chief commissioner of the London metropolitan police, and by Juan Vucetich of Argentina. Galton’s system served as the basis for the fingerprint classification systems developed by Sir Edward R. Their observations were experimentally verified by the English scientist Sir Francis Galton, who suggested the first elementary system for classifying fingerprints based on grouping the patterns into arches, loops, and whorls. However, finger impressions are preferred to those from other parts of the body because they can be taken with a minimum of time and effort, and the ridges in such impressions form patterns (distinctive outlines or shapes) that can be readily sorted into groups for ease in filing.Įarly anatomists described the ridges of the fingers, but interest in modern fingerprint identification dates from 1880, when the British scientific journal Nature published letters by the Englishmen Henry Faulds and William James Herschel describing the uniqueness and permanence of fingerprints. An injury that destroys the dermal papillae, however, will permanently obliterate the ridges.Īny ridged area of the hand or foot may be used as identification. Injuries such as superficial burns, abrasions, or cuts do not affect the ridge structure or alter the dermal papillae, and the original pattern is duplicated in any new skin that grows. The practice of utilizing fingerprints as a means of identification, referred to as dactyloscopy, is an indispensable aid to modern law enforcement.Įach ridge of the epidermis (outer skin) is dotted with sweat pores for its entire length and is anchored to the dermis (inner skin) by a double row of peglike protuberances, or papillae. Fingerprints serve to reveal an individual’s true identity despite personal denial, assumed names, or changes in personal appearance resulting from age, disease, plastic surgery, or accident. Fingerprints afford an infallible means of personal identification, because the ridge arrangement on every finger of every human being is unique and does not alter with growth or age.
