Pierre Margot is a Swiss forensics scientist known for his contribution to the invention of the first forensic light source Polilight for the detection of fingerprint, biological fluids and other evidence on the crime scene. This new technology was named by the Powerhouse Museum as one of the top 100 Australian innovations of the 20th century. It was a great revolution in the field of forensic identification since this light could be used at the crime scene, unlike lasers at that time.
