Alphonse Bertillon – Full Biographical Entry
Name:
Alphonse Bertillon
Membership Status:
Member Emeritus
Date of Birth – Date of Death:
April 23, 1853 – February 13, 1914
Field of Expertise:
Forensic science, criminal identification, photography, handwriting analysis
Notable Cases:
- Developed the Bertillon System (Anthropometry) – A method of identifying criminals using precise body measurements.
- Introduced Mugshot Photography – The first systematic use of photographs for criminal records.
- Forensic Handwriting Analysis in the Dreyfus Affair (1894) – Conducted controversial handwriting analysis in one of France’s most infamous legal cases.
- Crime Scene Photography Innovations – Introduced scalable measuring tools in crime photos, allowing precise scene reconstruction.
Contributions to the League:
Bertillon’s innovations in forensic documentation and criminal identification were revolutionary, allowing law enforcement to scientifically track and catalog offenders. His use of photography, measurements, and detailed case documentation became a standard in modern forensic investigations.
The League integrates his meticulous approach to evidence recording into its training, particularly in:
- Crime scene photography and reconstruction, ensuring that critical details are preserved for future analysis.
- Forensic handwriting comparison, a method still used in verifying documents and signatures.
- Identification and tracking of suspects, applying scientific principles to criminal record-keeping.
Though the Bertillon System was later replaced by fingerprint analysis, many of Bertillon’s foundational techniques remain essential in forensic investigations and continue to inform League casework.
Historical Commentary:
Bertillon revolutionized forensic science by introducing precise documentation methods, ensuring investigations relied on measurable, repeatable data rather than conjecture. His crime scene photography methods and suspect identification techniques paved the way for modern forensics and remain core components of League investigations.
Though some of his conclusions—such as his analysis in the Dreyfus Affair—were later disputed, his scientific contributions to crime-solving remain invaluable. As an Honorary Member of the League, Bertillon’s work continues to influence criminal investigation, forensic documentation, and scientific detective work.
