French educator Louis Braille was born #OTD in 1809. He was the inventor of a reading and writing system named after him, braille, intended for use by visually impaired people.
At just 15 years old, Braille began refining Barbier's system, developing a code based on a six-dot cell structure that allowed for efficient representation of letters, numbers, and even musical notation.
