Louis Braille became blind at the age of 3, when he accidentally stabbed himself in the eye with his father's awl. Louis' other eye went blind because of sympathetic ophthalmia.
At the very young age of 10, Braille earned a scholarship to the Institution Royale des Jeunes Aveugles (Royal Institution for Blind Yuth) in Paris, one of the fist of its kin in the world. However, the conditions in the school were not notably better. Louis was served stale bread and water, and students were sometimes abused or locked up as a form of punishment.
Braille, a bright and creative student, became a talented cellist and organist in his time at the school, playing the organ for churches all over France.
At the school, the children were taught basic craftsman skills and simple trades. They were also taught how to read by feeling raised letters (a system devised by the school's founder, Valentin Hay). However, because the raised letters were made using paper pressed against copper wire, the students never learned to write. Another disadvantage was that the letters weighed a lot and whenever people published books using this system, they put together a book with multiple stories in one in order to save money. This made the books sometimes weigh over a hundred pounds. The school only had 14 books. Louis had read every book.
