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.
