Access to communication in the widest sense is access to knowledge
Born in Coupvray, France. My father was a leatherworker. At age three, I was playing with his tools and an awl slipped into my eye. The infection spread to both eyes. Blind by five. Attended the Royal Institute for Blind Youth in Paris at 10. At 15, I adapted Charles Barbier night writing system into a six-dot cell that could represent any letter, number, or musical note. The Institute resisted my system for decades. The sighted administrators could not read it and felt threatened. It was adopted widely only after my death. Tip: The people who benefit most from your invention are not always the people who decide whether to adopt it. Persistence outlasts resistance. Six dots. Sixty-three combinations. Enough for any language on Earth.
