1, Louis Braille was born on1June 4, 809 in Couperet, a small town on the outskirts of Paris. At the age of 3, he was blinded by an accident. At his father's harness factory, he wanted to imitate his father's work. It's naive. He picked up a sharp awl to punch a hole. The awl got rid of it and stabbed him in the eye. The sudden change made him learn knowledge in a new way, but he could only understand everything by listening. When Louis won a scholarship for young blind people from the Royal College of Paris, everything got better. By the time he was 65,438+00 years old, most of the teachers there were teaching in languages, and the 65,438+04 famous books in the library were difficult to read, and Louis was very distressed (distressed). 3. Later, in 182 1, a retired soldier named Charles Barbier visited this school. Barbier passed on his night writing method consisting of 12 salient points to Louis. In this way, soldiers can learn high-level confidential information without making any noise on the battlefield, although this writing method is inconvenient for soldiers with vision. But it is very useful for Louis who is 12 years old. 4. When he was 15 years old, Louis reduced Barbier's 12 bumps to six and systematized them. He published the first book in Braille in history in 1829, but he didn't stop learning Braille. In 1837, he again. People are skeptical about this. Blind students can only teach themselves Braille, even at the Royal College where Louis stayed to teach after graduation. Braille was not listed as teaching content until his death, and it was not spread around the world until 1868. At that time, a group of British people, now knowing that they majored in blind education at the Royal College, adopted this braille. ,
