Phase 1: Terminology Origin. The term "Criminalistics" (derived from the German "Kriminalistik") emerged to represent a methodical, scientific method for investigating crimes.
Phase 2: Key Figures.
(1) Edmund Locard: A key figure in forensic science, known for his "exchange principle" (every interaction results in a trace). He founded the initial crime lab.
(2) Paul Kirk: A significant American criminalist who played a crucial role in advancing forensic science in the US. He defined criminalistics as "the science of individualization." He's often credited with popularizing the term in modern English.
(3) Alphonse Bertillon: Created anthropometry, a system for personal identification.
(4) Hans Gross: An Austrian magistrate and criminology professor, widely considered the "Father of Criminalistics." His 1893 publication, "Handbuch für Untersuchungsrichter als System der Kriminalistik" (Handbook for Examining Magistrates as a System of Criminalistics), first used the term to describe the integration of scientific fields for legal investigations. The name "Henry Fanids" appears to be a typo, likely intended to be Hans Gross.
Conclusion: Historical records attribute the coinage of the term to Hans Gross.
