Question

9
pignier picked a book from the shelf and sat down to read. i could tell i was too slow, he thought, as the director was flipping through the pages much faster than i was reading. after a few pages, he stopped and said, \you can do better.\
10
when pignier finished reading, the director turned to the raised dots on the back of the pages. in a moment of triumph, pignier, without hesitating, he read every word he had seen the director read, or almost. the same speed as the director had read them.
11
pignier couldnt believe his ears. he picked out another book, another passage, and asked louis to repeat the demonstration. then, rising from his desk with a burst of emotion, the director embraced louis and praised him.
12
soon the entire school was talking about louiss new language of raised dots. dr. pignier called an assembly to introduce the students and teachers to the new system. louis sat in the middle of a big classroom, working with his stylus as one of the sighted teachers read a poem aloud. the other sighted teachers leaned forward in their seats, watching louiss hand move across the paper. the blind instructors and students cocked their heads and listened as the point of the stylus punched out dots.
13
then louis stood up. he cleared his throat and recited the poem, his fingers moving as he spoke; without missing a word or making an error. when he finished, an excited murmur filled the room and everyone crowded around him.
14
louis was just fifteen years old when he demonstrated the first workable form of his system. during the next few years, he would continue to improve and add to his system, but he had already devised the basic alphabet that would open the doors of learning to blind people all over the world.
