The Braille system is the global reading and writing system for the blind. Louis Braille, the inventor, was also blind. He accidentally stabbed himself with his father’s work tools when he was three, due to an eye infection which led to blindness. He went to a school for the blind youth in Paris where he was frustrated by the embossed letters the teachers used to teach students how to read. When he was twelve, he was inspired by the demonstration of a former French army officer about a code of 12 embossed dots and dashes used at night to communicate combat orders. He was only 15 when he had developed a simpler system of six dots that can be easily felt with a fingertip.
