Each title in this series tells the story of a man or woman whose dedication to their chosen cause led to changes that affect all our lives today. Each includes a vivid description of the world in which the famous person lived. This book describes how one blind French boy developed a system of reading, in the early part of the nineteenth century, that opened up the world to blind people everywhere. His development of a system of dots to represent letters was based on a military method of night communications. Through his story, the reader also learns what life was like for blind people then, and what a difference Braille made to them, while accurate drawings show how the Braille system works.
