Catalogue Note
Rudolf Hell (1901-2002) revolutionised typesetting at his works in Babelsberg, Dahlem and Kiel before and after World War II, particularly the tele-printer or Hellschreiber, a precursor of fax machines. He invented the Klischograph 1951 for reproducing clichés or printing plates and developed it over the following decade, documented in these patent registrations. In 1963 he introduced a scanner and in 1965 the computer typesetter and the digiset.
