The first photograph of a human...

“Boulevard du Temple“, taken by Daguerre in late 1838 or early 1839 in Paris, was the first photograph of a person. The image shows a street, but because exposure time was over ten minutes, the traffic was moving too much to appear. The exception is the man at the bottom left, who stood still getting his boots polished long enough to show.”
