On a clear spring morning in 1838, the French painter and inventor Louis Daguerre positioned a tripod holding a small wooden box on the roof of his Paris studio. It was a camera obscura, a simple device used by centuries of artists to capture light and project inverted images. But Daguerre was attempting something revolutionary. Using light-sensitive chemicals and polished silver plates, he was trying to produce some of the world’s first high-resolution, lifelike photographs.
Daguerre aimed his rooftop camera at the bustling street scene below. The Boulevard du Temple, known to Parisians as the “Boulevard du Crime,” was home to a half-dozen popular theaters, and even at eight in the morning the street was filled with pedestrians, hawkers and horse-drawn carriages.
Daguerre opened the camera’s lens and timed the exposure for five minutes, long enough to fix a temporary image on the treated plate inside the box. Back in his studio, Daguerre completed the photographic process he'd been perfecting for 14 years, producing a shiny, crystalline image of the Boulevard du Temple that was an early example of what would become known as a daguerreotype.
That 1838 daguerreotype, titled View of the Boulevard du Temple, wasn’t particularly special to Daguerre. It was one of three test photos he took that same day to demonstrate how the daguerreotype process performed under different light conditions. Because of the minutes-long exposure times, the Boulevard du Temple appears to be completely empty in the photos. Anything in motion was rendered invisible or hopelessly blurred, including all carriages and pedestrians.
Except for one person.
In the lower left third of the photo taken at 8 a.m., there’s a man standing on the sidewalk near a bend in the boulevard. He appears to have one foot up on a box, presumably getting his shoes shined. The bootblack—or shoe shiner—is obscured from view. Daguerre didn’t intend to photograph the man, but he was the only living thing in frame that stood still for the full five-minute exposure.
The identity of the standing man is unknown, which is a shame, because historians now believe that Daguerre’s 1838 View of the Boulevard du Temple is the world’s oldest known photograph to clearly depict a person. Its story dates to the very invention of photography and was almost lost to history—twice.
