Kids' Science Challenge #20

Challenge Question

braille alphabet image I was born in France in 1809 and suffered an eye injury when I was three years old, causing me to lose sight in both eyes. I went on to study at the National Institute for the Blind in Paris. I adapted a "night writing" code used by the French army into a tool for the blind, which was formally introduced in 1824.

Who am I and what was the tool I created?
