On July 30, 1928, George Eastman demonstrated his “kodacolor” process that allowed anyone to make color motion picture films. He was 74 at that time and had never even finished high school. But his inventions, such as roll film, brought photography to the masses. I even remember my parents having a cheap Brownie camera. One wonders what he would have done with the technologies we have now.
It was front-page news in the New York Times of July 31, 1928 – you can read it by searching for “home movies in colors” in the ProQuest Historical Newspapers – The New York Times database.
There is more relevant material in Andersen Library’s collections; please ask a librarian for assistance.
