On this date in 1839, Louis Daguerre demo'd his process for producing pictures to a joint session of France's Académie des Sciences and Académie des Beaux-Arts. He called it a "daguerreotype." He took the earliest known photo of a person in 1838 (below). https://t.co/jPHyPQkJsA https://t.co/nwHUg6mfiz — PolitiTweet.org
