1829-Louis Braille of France invents Braille printing for the blind.  Braille is a system of raised dots that is read with the fingers, which, historically, has been embossed on paper.  The dots are a generally straightforward assignment of dot patterns to letters or words and punctuations.  Louis Braille was robbed of his sight around 3 years of age, though he passionately wanted to find a way to read, thus his invention of reading with your hands for the blind and semi-blind.  Today, it has been adapted to almost every language on earth.
