Victorian life was not easy at the best of times, but if you had a disability then life was even harder. Blinded in an accident when only a child, Louis Braille invented a representation for letters that any blind person could read by touch. At 15, this French teenage inventor used a series of bumps and no-bumps to represent each letter of the alphabet. He did not know that this technique was a form of binary representation, nor that it would form the basis of modern day computers.
