Robert Cornelius, self-portrait, October or November 1839, an approximately quarter plate size daguerreotype. On the back is written, "The first light picture ever taken".
"Boulevard du Temple", a daguerreotype made by Louis Daguerre in 1838, is generally accepted as the earliest photograph to include people. It is a view of a busy street, but because the exposure lasted for several minutes the moving traffic left no trace. Only the two men near the bottom left corner, one of them apparently having his boots polished by the other, remained in one place long enough to be visible.
