Robillard. Guillaume, Joseph. 24 ans, né le 17/11/68 à Vaucresson. Fondeur en cuivre. Anarchiste. 2/7/94. 1894

Alphonse Bertillon's "Robillard. Guillaume. 24 ans, né le 17/11/68 à Vaucresson. Fondeur en cuivre. Anarchiste. 2/7/94" is a photographic portrait from 1894 that exemplifies Bertillon's innovative approach to criminal identification. The image captures the subject, Guillaume Robillard, a copper smelter and anarchist, in a standardized frontal pose with a neutral expression, emphasizing features Bertillon believed were unique and measurable for identification. The inscription below the image includes Robillard's age, birthdate, profession, and political affiliation, reflecting Bertillon's system of "anthropometry." This work exemplifies the emergence of photographic portraiture in criminal investigations during the late 19th century.
