When Did Police Start Using Fingerprints?

Fingerprints have been used for identification purposes for centuries, but it was not until the late 19th century that police forces around the world began to recognize their potential as a forensic tool. The use of fingerprints in criminal investigations revolutionized law enforcement and laid the foundation for modern forensic science. In this article, we will explore the history of fingerprinting and its adoption by police forces worldwide.

The History of Fingerprinting

The concept of using fingerprints for identification can be traced back to ancient Babylon, where fingerprints were pressed onto clay tablets for business transactions. However, it was not until the 19th century that the scientific study of fingerprints began.

In 1892, Sir Francis Galton, a British scientist and cousin of Charles Darwin, published a book titled “Fingerprints.” Galton’s work laid the groundwork for the classification and identification of fingerprints. His research demonstrated that each individual has a unique set of ridge patterns on their fingers, which remain unchanged throughout their lifetime.

The first documented use of fingerprints in a criminal investigation can be credited to Sir William James Herschel, a British colonial official in India. In the 1850s, Herschel began using fingerprints as a means of authenticating documents and contracts. He believed that fingerprints could serve as a foolproof method of identification due to their uniqueness.

However, it was not until the late 19th century that the potential of fingerprints as forensic evidence started to gain recognition. In 1892, an Argentine police official named Juan Vucetich used fingerprints to solve a murder case, marking the first time fingerprints were used to identify a criminal.

The Adoption of Fingerprinting by Police Forces

The success of Vucetich’s case caught the attention of the international law enforcement community. Police forces around the world began to recognize the value of fingerprints as a means of identifying criminals and solving crimes.

In 1901, Sir Edward Henry, an Inspector General of Police in Bengal, India, developed a systematic method of fingerprint classification known as the Henry Classification System. This system provided a standardized way of categorizing fingerprints based on their patterns and ridges, making it easier to search and identify individuals from fingerprint records.

The use of fingerprints as a method of identification quickly spread to other countries. In 1903, the New York City Police Department established the first official fingerprint bureau in the United States. By 1906, the London Metropolitan Police had also established a fingerprint bureau, becoming the first in Europe to do so.

Over the years, advancements in fingerprinting technology and techniques have further enhanced its effectiveness as a forensic tool. Today, fingerprints are an integral part of criminal investigations worldwide, and their admissibility as evidence in courts is widely accepted.

12 FAQs about Fingerprinting:

1. How do fingerprints form?
Fingerprints begin to form in the womb and are influenced by genetic and environmental factors.

2. Are fingerprints truly unique?
While fingerprints are highly unique, there have been rare cases of individuals sharing similar ridge patterns. However, the probability of two individuals having identical fingerprints is incredibly low.

3. How are fingerprints collected at a crime scene?
Fingerprints can be collected using various methods including dusting with powder, lifting with adhesive tape, or using chemical techniques like cyanoacrylate fuming.

4. Can fingerprints be altered or disguised?
Fingerprints can be altered or temporarily obscured through intentional mutilation or by using substances like glue or tape. However, the underlying ridge patterns are usually still discernible.

5. Can fingerprints be used to determine a person’s age or gender?
Fingerprints cannot provide specific information about a person’s age or gender, as these characteristics are not encoded in the ridge patterns.

6. Can fingerprints be used to identify a deceased person?
Yes, fingerprints can be used to identify deceased individuals, even if the body is in an advanced state of decomposition. The ridges of the fingers are among the last body parts to decompose.

7. Can identical twins have the same fingerprints?
Although identical twins share the same DNA, they do not have identical fingerprints. The formation of fingerprints is influenced by factors beyond genetics.

8. Can fingerprints be used to solve cold cases?
Yes, fingerprints collected at the scene of a crime can be compared to those in a fingerprint database, potentially leading to the identification of a previously unknown suspect.

9. Can fingerprints be left on any surface?
Fingerprints can be left on various surfaces, but they are most commonly found on smooth and non-porous materials such as glass, metal, and plastic.

10. How long can fingerprints last on a surface?
Fingerprints can last for an extended period, ranging from days to years, depending on factors like environmental conditions and the quality of the surface.

11. Can fingerprints be removed or erased?
Fingerprints cannot be easily removed or erased. Even attempts to wipe them off may leave partial impressions or smudges that can still be analyzed.

12. Can fingerprints be used for purposes other than criminal investigations?
Yes, fingerprints are also used for non-criminal purposes, such as employee background checks, immigration applications, and access control systems.

In conclusion, the use of fingerprints by police forces began in the late 19th century, with the recognition of their uniqueness and potential as a forensic tool. The development of systematic fingerprint classification systems and advancements in fingerprinting technology have further solidified their role in criminal investigations. Today, fingerprints are a vital component of law enforcement and have greatly contributed to the successful identification and prosecution of criminals worldwide.
