Web Reference: Louis Braille, a student at the Royal Institute for the Blind (National Institute for Blind Children) in Paris in the 1820s, took a raised-dot system of code brought to the school in 1821 and turned it into the most-important advancement in blind education. 1920 Barr, Stroud, and Fournier d'Albe patent the optophone, the first reading machine for people who are blind, which translates printed letters into musical tones. The practice of institutionalizing the blind in asylums has a history extending back over a thousand years, but it was not until the 18th century that authorities created schools for them where blind children, particularly those more privileged, were usually educated in such specialized settings.
