Paris Gun
During World War I, the Krupp company manufactured large mortars that the German army used to bombard forts in Belgium and France. German troops nicknamed these various names of which "Dicke Bertha" ("Big Bertha") after Bertha Krupp von Bohlen und Halbach. Allied troops used the translated name, "Big Bertha," to refer to all German long-range artillery, particularly those that shelled Paris in 1918. However, "Big Bertha" entered the lexicon due to the Paris Gun, a piece of German artillery which was constructed of three artillery barrels welded together. It had a range of 75 miles and its appearance was a major surprise to Parisians in 1917 who had previously only come under attack from German aircraft, since previous artillery reached a maximum of thirty miles.
