Braille writting
Born in France in 1809, Louis Braille was blinded by an injury when he was only 3 years old. In 1824, while he was a 15-year-old student at the Royal Institute for Blind Youth in Paris, he created a type of reading that involved raised, imprinted dots organized in a pattern to facilitate learning. The first Braille book was released in 1829—and Louis Braille went on to become an instructor at the school where he had once been a student.
