Edmond Locard

Edmond Locard was a French criminalist known for establishing the principle that “every contact leaves a trace.” This means that whenever a person interacts with a space or object, they leave behind evidence such as fingerprints, hair, or other materials. Locard’s ideas laid the groundwork for forensic science, emphasizing the importance of collecting and analyzing physical evidence in criminal investigations. His work helped scientists and law enforcement understand that crime scenes can reveal crucial information that can lead to solving crimes and identifying perpetrators.
