Early Years

Locard was born in 1877 in the city of Lyon, France. He got his doctoral degree in medicine in 1902. Alexander Lacassagne a French medical doctor, adopted Locard as a mentor. Locard became an attorney later on. During World War I , Locard worked as a medical examiner and identified causes and locations of death He used the stains and dirt left on soldier's uniforms. In 1910, he opened the world’s first crime investigation lab in Lyons. Locard travelled around the world visiting police station which helped him grasp the anthropometric system of criminal identification. He wrote books in forensic science and he developed Locard’s Exchange Principle. His principle is still used today, along with many of his other accomplishments.

Pioneer in Forensic Science

Edmond Locard was a pioneer in forensic sciences. While he was studying medicine, he began to develop an interest in applying science to legal matters. He originally pursued a career in law. However, during first World War he worked as a medical examiner. He attempted to identify the cause of a soldier's death by stains and damage of the uniform. By 1910, a police department offered Locard the chance to form a police laboratory where crime scene evidence would be scientifically examined. During his time in the laboratory, he contributed to the improvement of dactylography, which is an area of study that deals with fingerprints, and he continued on to develop the science of poroscopy, the study of fingerprint pores and their impressions.

Leocard’s Exchange Principle

Leocard is mostly known for Leocard's Exchange Principle, which is a theory that relates to the transfer of evidence between objects. It stated that "every contact leaves a trace". The theory basically stated that when two object come in contact with each other, there will always be some evidence of the occurrence; the objects will each take something from each other or one of the objects will leave something behind. All of Leocard's work in forensic science has an extreme impact in modern day forensics. Fingerprinting is a common method for identifying criminals, and he was one of the very first people to ever take it to a scientific level. Leocard's Exchange Principle still applies to crime scenes today, and has become an influential piece of work in forensic science.
