Chaumelin. Odilon. 22 ans, né à Paris VIe. Publiciste. Anarchiste. 24/3/94. 1894

This is a portrait photograph of Chaumelin, a 22-year-old Parisian anarchist, taken by Alphonse Bertillon in 1894. Bertillon was a French criminologist known for developing the Bertillon system, an early method of criminal identification using anthropometric measurements. This photograph is an example of Bertillon's work, which used photography to record physical characteristics for identification and criminal investigation. Bertillonage, as it was known, was widely used by police departments across the world in the late 19th and early 20th centuries. The photograph is part of the Metropolitan Museum of Art's collection in New York City, and provides a unique glimpse into the history of criminal justice and early photography.
