This typewriter produces braille using the standard typewriter keyboard. Grade 1 braille is typed in lowercase. Both lower and uppercase characters are used for grade 2. The contractions for Grade 2 occupy the uppercase positions. In the 1860's, two Milwaukee inventors were busy developing a machine for consecutively numbering the pages of a book. One of the men, Carlos Glidden, came across an article describing a new British machine capable of printing typed letters, and he brought the article to the attention of his partner, Christopher Latham Sholes. If our machine could print page numbers, Sholes wondered, why couldn't it also print regular letters? By 1867, Sholes had constructed the first practical typewriter in his Milwaukee shop.

Until far into the nineteenth century, the students at the School for the Blind have to make do with 'writing boards' through which they push one or more of the six points of Braille in reverse. Headmaster Frank Haven Hall finds this much too time-consuming and invents a machine with which to write Braille. Gunsmith Gustav Sieber puts it together. Surprisingly fast. In 1892, Hall's first machines show what they can do: 58 words a minute from memory and 31 when dictated! Averse to commerce. Hall's intention was obvious: to give as many blind people as possible the chance to correspond with others. He is averse to personal gain and has the machines made for 10 dollars and sells them for 11. He doesn't even apply for a patent for his invention! Incidentally, he later also invents the electric clock
