'Moon' named after William Moon, is a system of reading by touch using raised letters based on the normal alphabet. It is thus simpler to learn than braille, especially for people who have become blind in later life. The RNIB was set up in 1868 by Thomas Rhodes Armitage. The installation of the autobraille pres in 1982 speeded up the production of braille.
