I asked a question about this image in this newsletter.

The Boulevard du Temple photograph of 1838 (or possibly 1839) is one of the earliest daguerreotype plates produced by Louis Daguerre. Although the image seems to be of a deserted street, it is widely considered to be the first photograph to include an image of people. (Wikipedia)

More to come, but to recognize here that it was a stretch … First Person … People First!
