 Prior to the 1930s, there were several regional variations of Hebrew Braille, but no universal system.In 1930, the Jewish Braille Institute of America, under the direction of the Synagogue Council of America, assembled an international committee for the purpose of producing a unified embossed code to be used by sightless people throughout the world.The committee membership consisted of Isaac Maletz, representing the Jewish Institute for the Blind, Jerusalem; Dr. Max Geffner, of the Blindeninstitut of Vienna; Canon C. F. Waudby, of the National Institute for the Blind, Great Britain; Leopold Dubov, of the Jewish Braille Institute of America; and Rabbi Harry J. Brevis, representing the New York Board of Rabbis.
