1 Blind and wanting to read — those were the realities

of Louis Braille’s life. The desire to read easily led to the

Braille system. January 4 is Braille Day. That day honors

the blind. But we should also remember Louis and what

he achieved by age 15.

3 Three-year-old Louis went to his father’s workshop.

Louis’s father was a saddle maker who made items out of

leather. Imitating his father, Louis tried to cut a piece of

leather with a small knife. His hand slipped, and the point of

the knife went into his eye. The doctors took care of him

the best they could, but the injured eye got infected. Then

the infection spread to his good eye. Louis became blind.

7 When Louis was 12, Charles Barbier, a French Arm

y officer, came to the school. Barbier developed an alp

habet code used by army soldiers. The code was used t

o deliver messages to the soldiers at night. It was

made up of dots and dashes. It kept the messages

secret even if the enemy would see them, but the code

was too complicated for the blind. Louis thought the cod

e was slow and the dashes took up too much space. Onl

picked up a blunt awl. Aha! An idea came to him. He
