>>In 1840, Johann Nikolaus von Dreyse invented the needle gun and a firearms factory was founded in the town. In 1919 the Rheinmetall company took over the factory, later called Rheinmetall-Borsig, at first to produce automotive parts. Initially it concentrated with only little success on carburettors, then in 1925 an ambitious new manager, the engineer Fritz Faudi, took over and a new type of cardan joint was developed, which became extremely popular. The Rheinmetall-Faudi system was a well-known name, and the Sömmerda works were the largest producer in Germany.

In April 1921 the factory returned to arms production, going against the post-war regulations which banned it from producing fuses. From October 1922 the factory produced the total quantity of fuses allowed in Germany by the Allies and also began producing the new MG30 machine gun under the direction of Louis Schmeisser.<<
