Administrative History: In the early 1960s, the American Printing House for the Blind began designing and building an electric powered, cabinet-model stereograph to emboss metal printing plates with braille. The work was done by employees in the company's Machine Shop, which would become part of the Maintenance Division formed in fiscal year 1979. By 1964, the APH Stereograph could be automatically run by computer keypunch cards via a connected card reader. Most APH Stereographs were retired in the late 1980s, in favor of the automatic Plate Embossing Device (PED).
