The Rear-View Mirror

Oliver Wendell Holmes, Sr., writing in 1859 (about 20 years after the first daguerreotypes appeared), called photography “a mirror with a memory.” [1] He writes,

“The man beholdeth himself in the glass and goeth his way, and straightway both the mirror and the mirrored forget what manner of man he was…”
