Edmond Locard founded the first police crime laboratory in 1910 in Lyon, France. It is impossible for criminals to flee a crime scene without leaving behind traces of evidence that can be used to identify them, according to Locard's "exchange principle."
This concept served as the foundation for the forensic sciences, a body of methods for collecting and analyzing physical evidence from crime scenes. The "Sherlock Holmes of France," French criminologist Edmond Locard, who founded forensic science, lived from 13 December 1877 to 4 May 1966. Every encounter leaves a trace, according to his formulation of the fundamental tenet of forensic science.
In the field of research that examines fingerprints, and dactylography, Locard made significant contributions that are well known.
Although Edmond Locard passed away in 1966, his exchange principle has had a significant impact on forensic science and is still widely cited today.
