Louis Braille (4 January 1809 – 6 January 1852) was a French educator and inventor of a system of reading and writing for use by the blind or visually impaired. His system remains known worldwide simply as braille. Blinded in both eyes as a result of an early childhood accident, Braille mastered his disability while still a boy.

Louis Braille was born in Coupvray, France, a small town about twenty miles east of Paris. As soon as he could walk, Braille spent time playing in his father's workshop. At the age of three, the child was toying with some of the tools, trying to make holes in a piece of leather with an awl. Squinting closely at the surface, he pressed down hard to drive the point in, and the awl glanced across the tough leather and struck him in one of his eyes. A local physician bound and patched the affected eye and even arranged for Braille to be met the next day in Paris by a highly respected surgeon, but no treatment could save the damaged organ. In agony, the young boy suffered for weeks as the wound became severely infected; an infection which then spread to his other eye, likely due to sympathetic ophthalmia.

In 1821, Braille learned of a communication system devised by Captain Charles Barbier of the French Army. Some sources depict Braille learning about it from a newspaper account read to him by a friend,[18] while others say the officer, aware of its potential, made a special visit to the school.[4][19] In either case, Barbier willingly shared his invention called "night writing" which was a code of dots and dashes impressed into thick paper. These impressions could be interpreted entirely by the fingers, letting soldiers share information on the battlefield without having light or needing to speak.

Braille was the intellectual and creative student,  played cello and organ at school in France.
