Literature for Blind Before Braille System One of the earliest systems whereby where-by the blind might read originated in Peru, where the alphabet was formed by knots on a length of string. In the Sixteenth century Francesco Lucas, a Spaniard, engraved characters charac-ters on wood for the blind, and in 1G-10 an arrangement of movable metal type was used in France, This plan failed through lack of funds and the blind had to revert to the wooden letters let-ters and pins stuck in cushions. Other devices for the blind were Doctor I'in-seaux's I'in-seaux's frame with a small handle into which metal letters could be inserted, in-serted, and a German scheme with letters cut in cardboard. Then Valentin Val-entin Ilauy realized the possibilities of embossed paper. It was at this school that Louis Braille was a pupil and he saw the superiority of the point system over the many others, including Gall's Moon type, that were causing confusion. His method Is now world-wide. The Koran has been transcribed into Braille, and the system sys-tem adapted to Chinese and Arabic. |
