Boston line letter

Boston line letter was a tactile writing system created by Samuel Gridley Howe in 1835, a popular precursor to the now-standardized braille.

Samuel Gridley Howe, the first director of the New England Asylum for the Blind (now Perkins School for the Blind), studied tactile printing systems in Europe and developed his own system of raised type called Boston line letter.

Howe's system was similar to raised letters designed by James Gall in Edinburgh, Scotland, in the 1820s.

[1] In 1835 Howe printed Acts of the Apostles, the first book produced in Boston line letter.

[2] Until replaced by dot systems this hybrid form of raised letters was the predominant embossed type for blind people in the United States and the choice of most of the schools.
