Boulevard du Temple taken by Louis Daguerre in 1838 is the first photograph of a person.  If you look closely, you can see a man standing on the street corner in the bottom left quadrant of the image.  Because the exposure time was 10 minutes, the traffic was moving too quickly to appear on film, while the man was standing still getting his shoes shined long enough to make history.  I am a firm supporter of “seeing is believing.”  Therefore, I believe that this man is not only the first on camera, but also the first human being ever.
