The story of Louis Braille
Many years ago, a boy called Louis lived in France with his parents. He was very inquisitive and was interested in everything that happened around him. His father was a saddle maker and made saddles for other people’s horses.
One day Louis took his father’s sharp knife – without his father’s permission – and tried to cut a piece of leather in his father’s workshop. He had never worked with the knife, which slipped and cut into one of his eyes. Within three days both eyes had become infected and shortly afterward he lost his sight. Both eyes were blind.
Louis remained interested in everything that happened around him, but soon discovered how difficult it is to be blind. He had to go to a special school for the blind and found their manner of reading very difficult. Letters were embossed on the pages – they stood out slightly – but it was difficult to read and reading was very slow.
He became determined to find an easier way to read. One day a military officer came to address the children at the school. He spoke to them, about the methods that they used to send messages at night. Louis got the idea to develop an alphabet using six raised dots. This kind of writing is called Braille, and it consists of a code of dots on paper. You read this writing by running your fingers over the raised dots.
Louis eventually became a teacher and taught at the school. He taught all the blind learners to read Braille, of course. This method represents a vast improvement of the technology and blind people are now able to read much more easily than previously and can therefore learn in the same way as normal learners.
