Boston Line Type is developed.

Devised by Samuel Gridley Howe, it consists of raised type letters imprinted on the page. The first successful printing process for the blind, it is introduced 10 years before the system of dots developed by Louis Braille in Paris in 1824. Howe goes on to establish the Howe Press, a printing department at the Perkins School for the Blind, that utilizes his new system, despite competition from the Braille system, the New York Point System, and the modified American Braille system. The press continues until 1908.
