Louis Braille was born in France in 1809 . His father had a small business . He

made shoes and other things from leather . Louis liked to help his father in the store

even when he was very small . One day when Louis was 3 years old , he was cutting

some leather . Suddenly the knife slipped and hit him in the eye . He soon became

completely blind . When he was ten years old , he entered the National Institute for

the blind in Paris . One day his class went to visit a special exhibit by a captain in the

army . One thing in the exhibit was very interesting for Louis . It showed message in

code . Armies send messages in secret codes so no one else can read them . The

captain wrote this code in raised letters on very thick paper .

Louis thought a lot about this code . Then he decided to write in the same way so

the blind could “read “ with their fingers . It is very difficult to feel the differences

between raised letters . Instead of letters , Louis used a “cell “ of six dots . He

arranged the dots with two dots across and the three down . So blind people can read

and write even write music by Braille .
