The Henry Classification System

The Henry Classification System is a scientific filing system based upon
alpha-numeric fingerprint identification and cataloging.  
There are varying stories as to when this science was internationally
introduced.  This science was
introduced to Americans in 1904 in St. Louis, MO. 
(Forensic Press, 2000). 
Fingerprint identification is formed from two factors, the hand ridge
permanence and the uniqueness of a person’s fingerprint pattern. 
A person’s fingerprint will be classified as having one of the three
general fingerprint patterns. The general patterns are loops, arches, or whorls
pattern types.  Each finger will
have one of these pattern types.     Sir Edward Richard
Henry developed a plan that classified fingerprints. 
The classification system was based upon a criminal having his or her
fingers inked and having the impressions placed on an identification card.  This system was devised so that
criminals could no longer hide their identity.  Sir Henry’s classification system has
saved numerous law enforcement departments from going through thousands
identification cards with false names and John Doe identifications. 
Sir Henry’s classification system has been used throughout the world and
continues to be practiced in the United Stated today. 
The Henry Classification system is a very detailed process. 
First the fingers are inked or placed onto LiveScan. 
The processor examines each fingerprint and assigns it an alpha-numeric
value depending upon the pattern types. 
The fingerprint impression will be classified as a loop, arch, or
whorl. After each print is
examined, the sum of the primary is formed.
