* Locard's Exchange Principle: This principle states that "every contact leaves a trace." This principle is fundamental to forensic science and is used in many areas of investigation, such as fingerprint analysis, DNA profiling, and trace evidence analysis.
Edmond Locard did not write books in the traditional sense. However, he published extensively in scientific journals and contributed to several books on forensic science, such as:
* The Crime of the "Bluebeard" (1928): A detailed analysis of a real-life murder case.
* The Criminal Investigation (1934): A comprehensive overview of forensic science techniques.
