Look toward the lower-left corner of Louis Daguerre’s Boulevard du Temple. Beneath the rooftops and beside the broad, apparently empty street, a tiny figure has one leg raised. Nearby is the person generally identified as a shoeshiner. They are easy to overlook in a picture dominated by buildings. Yet those two figures have become the reason generations of people keep looking at it.
Finding them in the photograph is straightforward. Finding the patch of present-day Paris where they stood took two years.
On October 15, 2026, Paris unveiled a bronze marker at the location identified by that investigation, now within Place de la République. Called Un détail imprévu, or “An Unforeseen Detail,” it commemorates the shoeshiner and customer in one of the earliest known photographs to show people. The City of Paris describes how the team tracked them down.
Background: the history of Daguerre’s photograph.
The street was not really empty
Daguerre made the image in 1838, pointing his camera toward the Boulevard du Temple from his studio. The long exposure explains its eerie stillness: people moving through the street did not register clearly, while the customer stayed in place long enough to leave a recognizable silhouette. A routine shoeshine became an extraordinary photographic accident.
The reproduction shown here preserves the familiar mirrored orientation. That distinction matters when you try to turn the picture into directions.
First, turn the photograph around
Filmmakers Maximilien Van Aertryck, Axel Danielson and Kalle Boman began their search in June 2024. They had to account for the image’s left-right reversal before matching it to the real streetscape.
The researchers assembled a 3D scan of the area alongside old maps, engravings and paintings. Three buildings visible in Daguerre’s picture still survive, providing crucial reference points. Two architecture firms, Sweden’s Rumlab and France’s Mater Studio, used different methods to locate the figures, as Van Aertryck explains in his account of the investigation.
Those surviving buildings were especially valuable because they linked the photographed scene to places that could still be measured. Without that connection, a familiar-looking roof or street corner would be a guess. The investigation worked backward from the present city toward a moment preserved on a nineteenth-century plate.
The original nearly vanished
The image itself had a much less fortunate journey. Daguerre’s presentation set went to Ludwig I of Bavaria, and the Bavarian National Museum’s collection record documents the triptych, its original frame and dedication.
According to the project account published by The Eye of Photography, damage and a later restoration attempt left the original image almost entirely erased. A reproduction made before that deterioration preserved the view people recognize today. The investigators were tracing a place from an image that had itself come close to disappearing.
There is still a distinction between locating the figures and naming photography’s undisputed first human subjects. Le Monde notes competing claims involving other early photographs. The safer description is that these are among photography’s earliest and most famous human figures.
The marker gives their ordinary encounter a physical address again. Their names remain unknown. You can now stand where the research places them, but the photograph still cannot tell you who they were.
