Siegfried Map

Extracted from the Wikipedia article Topographic Atlas of Switzerland.
The Topographic Atlas of Switzerland (German: Topographischer Atlas der Schweiz), also known as the Siegfried Atlas or Siegfried Map (German: Siegfriedkarte; French: Carte Siegfried), is an official map series of Switzerland. Its publication was begun by the Federal Topographic Bureau under Hermann Siegfried, and continued from 1870 to 1926. During this period the individual maps were drawn by different lithographers, including Walter Hauenstein, Georg Christian von Hoven and Rudolf Leuzinger. Since it is, in today's parlance, not strictly an atlas but a map series, map historians now describe it only by the expression Siegfried Map.
