Josef Lauff (16 November 1855 – 1933) was a German poet and dramatist.
He was educated at Münster in Westphalia, and entering the army served as a lieutenant of artillery at Thorn and subsequently at Cologne, where he attained the rank of captain in 1890.
In 1898 he was summoned by the German emperor, William II, to Wiesbaden, being at the same time promoted to major's rank, in order that he might devote his great dramatic talents to the royal theatre.
[1] His literary career began with the epic poems Jan van Calker, ein Malerlied vom Niederrhein (1887, 3rd edition, 1892) and Der Helfensteiner, ein Sang aus dem Bauernkriege (3rd edition, 1896).
Beginning with the tragedy Inez de Castro (1894), he proceeded to dramatize the great monarchs of his country, and, in a Hohenzollern tetralogy, issued Der Burggraf (1897, 6th edition 1900) and Der Eisenzahn (1900), to be followed by Der grosse Kurfurst (The Great Elector) and Friedrich der Große (Frederick the Great).
