Moon was born in
Horsmonden,
Kent. As a small child, he lost sight in one
eye from
scarlet fever, and by the age of twenty-one he had become totally
blind. He moved in with his widowed mother and sister in
Brighton,
East Sussex. He became a teacher, and taught boys how to read using the existing
embossed reading codes. Moon realised that the boys found these reading codes difficult to learn. He devised a new system, Moon type, based on a simplified
Latin alphabet, which he designed to be easier to learn. ==Family==
