Born in 1877, Dr Edmond Locard was a French criminalist renowned for being a pioneer in forensic science and criminology, often informally referred to as the “Sherlock Holmes of France”. Whilst studying medicine he developed an interest in the application of science to legal matters, writing his thesis on Legal Medicine under the Great King (La medecine legale sous le Grand Roy).
Edmond Locard is perhaps most well-known for his formulation of Locard’s Exchange Principle, a theory relating to the transfer of trace evidence between objects, stating that “every contact leaves a trace”. The theory dictates that when two objects come into contact with one another, each will take something from the other object or leave something behind.
