Dr. Edmond Locard (13 December 1877 – 4 May 1966)
Dr. Edmond Locardwas a pioneer in forensic science who became known as the Sherlock Holmes of France. He formulated the basic principle of forensic science: "Every contact leaves a trace". This became known as Locard's exchange principle.
Locard studied medicine and law at Lyon, eventually becoming the assistant of Alexandre Lacassagne, a criminologist and professor. He held this post until 1910, when he began the foundation of his criminal laboratory. He produced a monumental, seven-volume work, Traité de Criminalistique. He continued with his research until his death in 1966.
In 1910 Locard succeeded in persuading the Police Department of Lyon (France) to give him two attic rooms and two assistants, to start what became the first police laboratory.
