Barbie is system was difficult. But it gave Louis an idea. He worked night after night to make a simple system with dots. By age fifteen he had finished his system. He showed it to other students in the school. And they loved it. They called it Braille after him. At age seventeen. Louis graduated from the school and became a teacher there. In his free time he copied books into Braille. Someone read to Louis while he made the dot. He copied the books of Shakespeare and other writers into Braille. The students read all the books and wanted more. The school did not want a fifteen-year-old boy is invention to be better than their own heavy books and would not let students read Braille books. Nevertheless the students continued to read them. Finally after twenty years the school agreed to use Braille.
Louis Braille spent the rest of his life trying to tell the world about Braille. But nobody cared. Louis was unlucky again. He became very
Sick. Even when he was sick in his bad he continued to write books in Braille for the students at his school. A few years later Louis Braille died at age forty-three. Two years after he died schools for the blind began to use his system.
