The story
The company was founded in 1873 as a metal foundry and fittings factory under the Jürgens & Co. company. It was taken over by Eugen Polte in 1885 and entered in the commercial register in 1887 as Armaturenfabrik Polte ('Fittings Factory Polte'). The company operated under the name of Polte (often referred to as Polte-Werke) from 1885 to 1945. During this 60-year period, the company remained a family business and was owner-managed. On Eugen Polte's death in 1911, running the Polte works was continued by his sons-in-law Martin Nathusius and Arnulf Freiherr von Gillern; it expanded to become one of the largest German ammunition suppliers before and during the Second World War.
In contemporary catalogues, price lists and advertisements, the company appeared under names such as Polte metal goods factory, Polte fittings and machine factory, Polte machine tools, Polte aluminum factory, Polte fittings and water meter factories, Polte cartridge, ammunition machine and fittings factory, Polte fittings and cartridge factory or Polte Munitions Factory – with or without the addition of 'Magdeburg'.
C. Louis Strube AG of Magdeburg belonged to Polte-Werke from 1913 onwards.
From 1931, around a dozen other production facilities outside Magdeburg, mainly in central Germany at the time, were taken over, built or leased and operated as branches or subsidiaries; in addition to the main plant ("old plant") in Magdeburg-Sudenburg, another plant in Sudenburg (the Fichtestraße plant) and the "plant II" (or "new plant") in Magdeburg-Wilhelmstadt, the Polte works operated 15 other factories in Germany until 1945. These plants were partly subsidiaries and partly Reich-owned or third-party plants that were leased and operated by Polte oHG.
