Louis Braille
Louis Braille (1809-1852) was a French educator and inventor who, blinded in an accident at age three, devised a tactile reading and writing system at the age of fifteen. His six-dot braille code enabled visually impaired people to read and write independently for the first time. Though largely rejected by sighted educators during his lifetime, braille was adopted worldwide after his death and remains the global standard for tactile literacy, virtually unchanged after two hundred years.
