“Boston Line Type” or “Boston Line Letter” was a tactile printing system invented by Samuel Gridley Howe. These letterforms contained no capital letters and represented an angular version of Roman letters. This printing system served as a precursor to the now widespread use of Braille lettering, as a way to grant reading abilities to the visually impaired.
