American Printing House for the Blind
American Printing House for the Blind (APH) is the world's largest nonprofit organization which creates educational and independent living products and services for people who are blind and visually impaired.
APH was founded in 1858 by the General Assembly of Kentucky with the mission to produce embossed books for the blind. In 1879 the United States Congress passed the Act to Promote the Education of the Blind, designating APH the official supplier of educational materials to students across the U.S. meeting the definition of blindness.
APH manufactures textbooks, cookbooks, dictionaries, and recorded books and in 2007 introduced the Braille+™ Mobile Manager, a small, talking PDA with a braille-style keyboard. The Braille+ includes a myriad of functions, such as a word processor, calendar, wireless internet access, audio recorder, and an MP3 player.
