sep 22, 1927 - BRAILLE INVENTED

Description:

Louis Braille, who was blinded at the age of three, invented the braille system in 1824 while a student at the Institution Nationale des Jeunes Aveugles (National Institute for Blind Children), Paris. Braille is read by passing one's fingertips over characters made up of an arrangement of one to six embossed points. The relative positions of these points represent different alphanumeric characters. Braille can be written with a Braillewriter (similar to a typewriter) or by using a pointed stylus to punch dots through paper using an instrument called a Braille slate, which has rows of small cells in it as a guide.3 Braille has since been adapted to almost every known language and is an essential tool for blind people everywhere.
