Henry Faulds
From Wikipedia, the free encyclopedia
Dr Henry Faulds (1 June 1843 - 1930) was a Scottish scientist who is noted for the development of fingerprinting.
Faulds was born in the Scottish town of Beith. Aged 13, he went to Glasgow to work as a clerk; at 21 he decided to enrol at Glasgow University, where he studied mathematics, logic and the classics. He later studied medicine at Anderson's College.
Following his education he became a missionary and was sent to Japan, where he became the superintendent of Tuskiji Hospital, Tokyo and founded the Tokyo Institute for the Blind. Whilst accompanying a friend to an archaeological dig he noticed how the delicate impressions left by craftsmen could be discerned in ancient clay fragments. Examining his own fingertips and those of friends, he became convinced that the pattern of ridges was unique to each individual.
Shortly after these observations his hospital was broken into. The local police arrested a member of staff who Faulds believed to be innocent. Determined to exonerate the man he compared the prints left behind at the crime scene to those of the suspect and found them to be different. On the strength of this evidence the police agreed to release the suspect.
In an attempt to promote the idea of fingerprint identification he sought the help of the noted naturalist Charles Darwin. Darwin declined to work on the idea, but passed it on to his relative Francis Galton, who forwarded it to the Anthropological Society of London. When Galton returned to the topic some eight years later, he paid little attention to Faulds letter. As a result of this interchange some controversy has arisen about the inventor of modern forensic fingerprinting. However, there can be no doubt that Faulds' first paper on the subject was published in the scientific journal Nature in 1880; all parties conceded this.
The following month Sir William Herschel, a British civil servant based in India, wrote to Nature saying that he had been using fingerprints (as a form of bar code) to identify criminals since 1860. However, Herschel did not mention their potential for forensic use. Over the years, Faulds conducted a bitter controversy with Herschel over the use of fingerprints, demanding proof in 1894 that Herschel had ever used fingerprints officially, which Herschel duly provided, and then writing a series of books and pamphlets many years later containing variations of the argument that he had been cheated his due credit (see [1] for complete facsimiles of these and other fundamental works on fingerprinting, and the Herschel/Faulds letters). These books were published from 1905 onward, long after fingerprinting had come into widespread use.
Returning to Britain in 1886, after a quarrel with the Missionary society which ran his hospital in Japan, Faulds offered the concept of fingerprint identification to Scotland Yard but he was dismissed, most likely because he did not present the extensive evidence required to show that prints are durable, unique and practically classifiable. Subsequently, Faulds returned to the life of a police surgeon in the Stoke-on-Trent town of Fenton. In 1922 he sold his practice and moved to nearby Wolstanton where he died in March 1930 aged 86.
Faulds did not believe that individual finger prints were unique and argued throughout his life for a classification scheme based on full sets of ten prints, where the combination of each finger pattern, at the arch-whorl-loop etc. level, forms a ten-part identifier of the set. Actual forensic use of fingerprints depended at its outset, as it does today, on single-print matches, using minutiae within each print rather than just the broad pattern exhibited by it. Faulds did not anticipate this, and died believing it to be fallacious.
[edit] Legacy
As a purely practical matter, Faulds had no direct effect on the development of finger printing and its adoption by criminal justice systems internationally. None of his publications contain any substantial data of his own about the actual occurrence and characteristics of fingerprint patterns. He does deserve credit, however, for being an early investigator and advocate of the broad notion of using fingerprints forensically, even if he never grasped the form this took practically.
