7. Who provided the inspiration for Louis Braille's invention of a method of reading and writing for the blind?
From Quiz Louis Braille
Answer:
Charles Barbier
In 1821 a French army officer, Charles Barbier, presented his night writing code at the school. He created this tactile code to help soldiers communicate during the noise and confusion of battle and also at night so that a light would not betray them to the enemy. The system used 12 raised dots. It was based on sounds and did not have symbols for the actual letters of the alphabet or punctuation marks. Louis created a 6-dot Braille cell, half the size of Barbier's cell. The Braille cell consists of two vertical rows of three dots. There are 64 possible combinations of these 6 dots. He created symbols for the letters of the alphabet, numbers and punctuation marks. He also created a code to read and write musical notations. Unlike Haüy's embossed print letters and Barbier's 12-dot cell, the Braille cell was just the right size to read with the fingertip.

Morse Code was created by Samuel Morse in 1838.
Laura Bridgman, although not as well known as Helen Keller, was the first deaf-blind person to learn language. She was born in 1829, five years after the invention of the Braille alphabet.
Helen Keller was born in 1880. Commenting on the importance of Louis Braille's invention Keller said, "We the blind are as indebted to Louis Braille as mankind is to Gutenberg."
