When he was just 12 years old he heard about an Army captain who had invented a communication tool which would allow soldiers to communicate in the dark of night. He met with the captain and then took the concept and at the age of 15 introduced a new reading tool for the blind called Braille.
By the age of 24, he became a college professor who taught history, geometry, and algebra. He was the organist for his church. He never married and died at the age of 43 from tuberculosis.
Isn't it amazing that his terrible handicap at such a young age turned into something that has helped millions of people. Can you even imagine not being able to read?
