Union, AG for mining, iron and steel industry
The Dortmunder Union was founded in 1872 at the instigation of Adolph von Hansemann (banker of the Disconto-Gesellschaft ) together with the banks Sal. Oppenheim and MA Rothschild & Sons . It emerged from the merger
- the Hattinger Henrichshütte AG with the Carl Friedrich Erbstollen colliery ,
- of the Mining and Huts Association of Nova Scotia in Essen-Horst and
- the Dortmunder Hut .
In 1880 the Union - like many other steel companies - acquired a license for the Thomas process and in the following year expanded its pig iron production capacity in Dortmund with a blast furnace system with three furnaces. In 1884/1885 the blast furnace facility at Henrichshütte was modernized.
In 1886/1887 the Brockhauser Tiefbau colliery , which separates with the Carl Friedrich Erbstollen colliery, was acquired. The joint funding of both companies was then relocated there. In 1898/1899 the Dortmund Adolf von Hansemann colliery was incorporated into the Union and the bridge building workshop in Dortmund was expanded.
In 1910 the union was taken over by the German-Luxemburgish Mining and Hütten-AG (Deutsch Lux, DL), which was particularly interested in the industrial companies of the group. During the First World War , the Union was one of the most important war suppliers with large grenade production.
During the National Socialism there was a subcamp of the Buchenwald concentration camp on the premises of the Dortmund Union . Between 400 and 650 girls and young women, mainly Russians and Polish women, were interned here and had to do forced labor in the armaments industry. In 1945 the prisoners were brought to Bergen-Belsen , some were shot in the Bittermark (see final phase crimes ).
After the Second World War, Dortmund-Hörder Hüttenunion AG was founded in 1951 in the course of the unbundling of Vereinigte Stahlwerke AG and the reorganization of the German iron and steel industry ; this was taken over by Hoesch AG in 1966 .
