WebIn 1796 German actor and playwright Alois Senefelder invented lithography (from Greek λίθος - lithos, 'stone' + γράφω - graphο, 'to write') as a cheaper way of publishing his plays. Lithography was the first planographic printing process, and the first radically new method of printing since Gutenberg’s invention of printing by ... Webby Maria S. Holden. The discovery of lithography was significant to the history and development of cartography. Prior to the birth of lithography at the turn of the 19th century, most maps and atlases were produced by engraving—a technique that requires much skill and labor. Engraved maps were rare and relatively expensive.
