INTRODUCTION
With the advancement in science and technology the
concept of crime as well as the methods adopted by
criminals in its commission have undergone a
phenomenal change.
On one hand the intelligent criminal has been quick to
exploit science for his criminal acts, on the other hand
the investigator is no longer able to rely on ageold art of interrogation and methods to detect crime.
In this context forensic science has found its
existence.

MEANING
Forensic science is the scientific method of
gathering and examining information about the past.
This is especially important in law enforcement
where forensics is done in relation to criminal orcivil law, but forensics are also carried out in other
fields, such as astronomy, archaeology, biology and
geology to investigate ancient times.
According to Hall Dillon, “The word “forensic”means “pertaining to the law”; forensic science
resolves legal issues by applying scientific
principles to them.”

ANCIENT HISTORY
Archimedes is considered as the father of forensic
science. He had found out that a crown was not made
of gold, (as it was falsely claimed) by its density and
buoyancy. After Archimedes, another early forensic science
application was done by Soleiman, an Arabic
merchant of the 7th century. He used fingerprints as a
proof of validity between debtors and lenders.

ANCIENT HISTORY (CONTD.)
In seventh century BC, Agnivesa Charaka Samhita, an Indian Medicine Treatise, was composed.Shushruta Samhita was composed between 200 and300 AD and its chapters concerning forensic
medicine in no way inferior to modern knowledge onthe subject.
In the 700s, the Chinese also used the fingerprintconcept.
The first document that mentions the use of Forensicsin legal
matters is the book Xi Yuan Ji Lu (translatedas “Collected Cases of Injustice Rectified”) written in1248.

HISTORICAL DEVELOPMENT
Pathology (1540s) - In the 1540‟s the French doctor
Ambroise Pare laid the foundations for modern
forensic pathology through his study of trauma
on human organs. He systematically studied theeffects of violent death on internal organs. Writings
on this topic began to appear in late 18th century.
Toxicology (1800s) - Matheiu Orfila
is known as the
father of modern
toxicology. In the early part of the
19th century he established in Paris methods of
scientific chemical analysis of poison, which are in
use even today.

HISTORICAL DEVELOPMENT
(CONTD.)
In India, during the nineteenth century, the cases of
death due to poisoning posed a problem to the law
enforcement agencies. The first Chemical Examiner's
Laboratory was, therefore, set up at the then MadrasPresidency, under the Department of Health, during
1849. Later, similar laboratories were set up at
Calcutta (1853), followed by one each at Agra (1864)
and Bombay (1870).

Ballistics (1820s) - Eugene Francois pioneered thefirst use of ballistics and began taking plaster casts ofshoe imprints.
Henry Goddard at Scotland Yard perfected thescience of ballistics and pioneered the use of bulletcomparison in 1835.
In India, in 1930, an Arms Expert was appointed and
a small ballistic laboratory was set up under theCalcutta Police to deal with the examination offirearms.

Anthropometry (1879) - In 1879, Alphonse Bertillon
of France, developed the science of Anthropometry
i.e. a systemic procedure of taking a series of body
measurements to distinguish one individual fromanother.
In India, the identification of criminals was done by
remembering their faces by the police. With the
invention of photography, the CID started
maintaining the records of the criminals using the
photographs.

HISTORICAL DEVELOPMENT
(CONTD.)
With the invention of Bertillon's anthropometric
system in 1879, India, adapted this system of
personnel identification and thus an Anthropometric
Bureau, for maintaining anthropometric records ofcriminals, was established in 1892 at Calcutta.
Fingerprints (1892) - Sir William Herschel was one
of the first to advocate the use of fingerprinting in the
identification of criminal suspects while working for
the Indian Civil Services.

HISTORICAL DEVELOPMENT
(CONTD.)
Francis Galton undertook the first systematic study of the
fingerprint and developed a methodology of classifying
the fingerprints.
In 1892, he published a book on fingerprints
giving asound statistical proof of uniqueness of individualization
through fingerprints.
In India, Henry approached the Government to seek
approval for replacing the anthropometric data byfingerprints for the identification of habitual criminals.
The first fingerprint bureau in India opened at Calcutta in
July 1897.

Serology (1901) - Karl Landsteiner in 1901
discovered that blood could be grouped into different
categories.
In 1910, Dr. Leone Lattes of Italy devised a
procedure for determining the blood group of dried
bloodstains and immediately adopted this technique
for criminal investigation. In India „Serology Department‟ was established in
Calcutta in 1910 and its name was changed to „Office
of the Serologist and Chemical Examiner‟ after
independence.

HISTORICAL DEVELOPMENT
(CONTD.)
Principle of Exchange (1910)- Edmund Locard is
responsible for this famous principle forming the
basis of modern forensic science.
Its states that “every contact leaves a trace”. This formed the foundation of trace evidence
collection and analysis for over a century and still
plays a central role in 21st century forensic science.

DNA Profiling (1984) - Sir Alec Jeffery developed a
science of DNA profiling and found that every
human being has a unique DNA structure. He
realized the scope of DNA fingerprinting, which usesvariations in the genetic code to identify individuals.
In India, the first Forensic DNA Typing facility was
established at CFSL, Calcutta, during 1998. The
implementation of this state of the art technique
represents significant advancements in the forensic
biology in the country.
