American Printing House for the Blind


The American Printing House for the Blind (APH) was founded in 1858, making it the oldest institution of its kind in the U.S. The APH manufactures braille, large type, recorded, computer disk, and tactile graphic publications as well as other products. The APH's research and development branch uses the wide-ranging expertise of electrical and software engineers to design such products as the Portabraille, a breakthrough technology that lets blind individuals read, write, and edit information more easily and quickly than ever before. The APH museum, endowed by former General Electric engineer Eugene Callahan, features many hands-on activities.

Fun Fact:Braille, a method of reading by touch, uses raised dots arranged in two lines of up to three dots each, much like a domino. A total of 64 permutations is possible. Invented in 1829 by French educator Louis Braille, the system was based on a method devised by a French army engineer for sending secret messages that could be read in the dark.
