Louis Braille
Back in the nineteenth century, when Louis Braille was just three years old, an accident left him blind. As he grew, Louis wanted to read and write, but he felt frustrated with the few slow, difficult methods available at the time for blind people.
So Louis came up with an idea, and as a teenager, he invented a special “language code” that would help make it much easier for blind people to read and write.
