Step 1: Know the key figures in forensic science history.
Several scientists shaped forensic science - Alphonse Bertillon (body measurement system), Hans Gross (systematic criminal investigation), and Cesare Lombroso (criminal anthropology). But one scientist is credited above all others with founding modern forensics.
Step 2: Identify the Father of Modern Forensic Science.
Dr. Edmond Locard established the world's first crime laboratory in Lyon, France in 1910. He is famous for "Locard's Exchange Principle" - every contact between a criminal and a crime scene leaves a mutual trace. This principle underpins all physical evidence collection in forensic science.
Step 3: Distinguish Locard from the others.
Bertillon is known for Bertillonage (body measurement ID), Lombroso for criminal anthropology, and Hans Gross for criminalistics. It is Locard's laboratory and exchange principle that earn him the specific title of Father of Modern Forensic Science.
