If you enjoy reading my blog, you could consider supporting me on Patreon. Back in 1785, a Frenchman named Valentin Haüy founded the Institute for Blind Youth in Paris.
It was a revolutionary idea, but with its downsides: the fancy and curly fonts of that time made it very hard for blind people to distinguish between letters; furthermore, it was also rather expensive to print such books.
He was going to start the first school for blind children in the U.S. and wanted to do practical research.
Both Haüy's method and Boston Line Type aimed to write text that was accessible both for blind and seeing people.
