#4 Braille Was Invented By A 15-Year-Old

As a small child, Louis Braille was blinded by an accident at his father’s workshop; even before his 10^th birthday, he had developed a mastery over that blindness; and as a young man of 15 years– still a student at school – Braille created a revolutionary form of communication that helped to overcome the blindness and transform the lives of millions around the world.

Inspired by a French army captain who developed Sonography, a visual-free system of writing for French soldiers, Braille set out to develop one on his own - A system to understand world through fingers. After three long years, the blind boy was indeed successful in developing an ingenious system of reading and writing by means of raised dots.

Today, even after two centuries and slight modifications, Braille remains as the standard form of writing and reading used by blind persons, in virtually every language throughout the world.
