Ernst Amandus Theodor Litfaß (or Litfass; German pronunciation: (11 February 1816 – 27 December 1874) was a German printer and publisher. He invented the free-standing cylindrical advertising column which bears his name in German (Litfaßsäule).
In 1854 Litfaß proposed putting up columns in the streets of Berlin for announcement and advertising purposes. Allegedly, he was disgusted by the unsystematic and ubiquitous posting of pamphlets, notices and other materials on walls, doors, fences and trees. In December that year he was granted permission to erect such Annoncier-Säulen columns, and on 1 July 1855 the first 100 Litfaß-Säulen were presented in Berlin.
