Letellier. Louis, Auguste. 29 ans, né à Rouen (Seine-Inférieure). Employé. Anarchiste. 23/4/92. 1892

This photographic portrait of Louis Letellier was taken by Alphonse Bertillon in 1892. The photo is part of a series of mugshots created for the French police in the 19th century. Bertillon was a pioneer in the field of criminal identification, known for his anthropometric system which measured various body parts. The image was used as a tool for police identification and is a document of its time, offering a glimpse into the development of forensic science. This small-scale photograph is now part of the collection of the Metropolitan Museum of Art.
