Frank H. Hall (Superintendent of the Illinois Institution for the Blind) invented the first Braille writer in 1892. The most popular and durable one now in use was invented by David Abraham. The Braille writing system itself was invented by blind Louis Braille, who was French, between 1821 and 1824.
Unfortunately, only a minority of blind people know and use braille. This is for a variety of reasons, but the most common are: --many people become blind when they are elderly and do not want to take the time and effort to learn braille --technology, especially recorded books and text-to-speech engines are replacing many documents that were previously provided in braille --there are not enough braille teachers to instruct blind students now that most blind students are mainstreamed instead of being sent to special segregated residential schools for the blind
