Klein. Louis. 25 ans, né le 8/8/67 à Colmar (Alsace). Employé de commerce. Anarchiste. 11/3/94. 1894

This photographic portrait, titled "Klein. Louis. 25 ans, né le 8/8/67 à Colmar (Alsace). Employé de commerce. Anarchiste. 11/3/94.", is part of Alphonse Bertillon's influential system of criminal identification, known as anthropometry. Bertillon, a French police officer, developed this method in the late 19th century, using detailed measurements and photographs to create a unique profile for each individual. The portrait, taken in 1894, depicts Louis Klein, a 27-year-old employee and anarchist, showcasing the system's focus on precise documentation and categorization. This photograph is a significant example of early photographic practices in criminology and its use as a tool for social control.
