Braille Family HomeSome Famous InventionsBISome Famous Discoveries(1)(1)(1)(1)BI-LouisLouis Braille(18091852)Louis Braille was a blind Frenchman who invented the braille system of printing and writing for the blind.He was born near Paris.An accident at age 3 followed by a serious infection left him blind.He entered the Royal Institution for Blind Youth in Paris(now the National Institution for Blind Youth)when he was 10.Braille was a good student,especially of science and music,and he became a church organist.He remained at the Institute as a teacher.There he developed his system of reading.(From the 1998 World Book Multimedia Encyclopedia)(1)(1)(1)(1)Braille Braille is a code of small,raised dots on paper that can be read by touch.Louis Braille,a 15-year old blind French student,developed a raised dot reading system in 1824.The idea came to him from the dot code punched on cardboard that Captain Charles Barbier used to send messages to his soldiers at night.In 1829,Braille published a dot system,basing it on a“cell“of six dots.From the 63 possible arrangements of the dots,Braille worked out an alphabet,punctuation marks,numerals,and,later,a system for writing music.His code was not officially accepted at once.But later it won universal acceptance for all written languages and for mathematics,science,and computer notation.Blind people read braille by running their fingers along on the dots.They can write braille on a 6-key machine called a braillewriter,or with a pocket-size metal or plastic slate.Braille books are pressed from metal plates.The characters are stamped on both sides of the paper by a method called inter-pointing.Dots on one side of the page do not interfere with those printed on the other.In the early 1960s,publishers began using computers to speed up production of braille books.The text is typed BI-Braille-1(1)(1)(1)(1)into a computer that automa-tically translates it into braille.The computer then transfers the raised braille figures onto paper or onto metal plates for use in a press.By another method,a vacuum braille former duplicates hand-transcribed braille pages on plastic sheets,which are then bound in volumes.(From the 1998 World Book Multimedia Encyclopedia)BI-Braille-2(1)(1)(1)(1)The Village of Coupvray BI-Village-1 The village of Coupvray is situated on the slopes of a grassy hill set between the Brie region of France and that of the Champagne province.In spite of the proximity of the Marne Valley,it retains even today the character of a rural village.One may still see the small brown-tiled roofs,the farmyards,the farmhouses and a village green surrounded by trees where are clustered together St.Pierre Church(where Louis Braille was christened on January 8,1809),the village hall,and the monument set up in 1887 and topped by a bust of the inventor of the alphabet for the blind.The body of Louis Braille rested in the village cemetery till 1952.On his tomb can be seen a casket in which the remains of his hands are preserved those hands which were the first in the world to finger the raised dots of t h e B r a i l l e a l p h a b e t.A l l a r o u n d i s s t i l l o p e n c o u n t r y.(1)(1)(1)(1)BI-Village-2Here and there amid the gardens and orchards,small grassy paths meander across the hillside.And,on the lower slopes,is an old wash-house with wooden posts and mossy tiles where the clear waters flow swiftly by,gently murmuring.(From Braille Family Home The Braille family home is in the lower part of Coupvray at the end of a small street which in the past went by the name of Knoll Street.It is a large solid house,built in the latter half of the 18th century and restored at various times since then.The Braille family also owned several farm buildings in the yard and on the opposite side of the street.A marble tablet was affixed in 1952 to the wall of the house facing the yard.The text,in French and English,reads:(1)(1)(1)(1)BI-cac2The
