Deutsch-Luxemburgische Bergwerks- und Hütten-AG

It was founded in 1901 at the initiative of Bernhard Dernburg and Hugo Stinnes[1] as the successor to the Lorraine-Luxembourg Steelworks Association and grew rapidly through acquisitions and mergers.

Due to its rapid expansion pace, it was always severely undercapitalised and financed itself through constant capital increases and bond issues.

The DL included the Dannenbaum, Friederika, Prinz Regent, Friedlicher Nachbar, Baaker Mulde, Hasenwinkel, and Julius Philipp pits.

Due to the regional division into various mining areas and distribution across different locations, the DL had a considerably more complex organisational structure than its competitors - such as August Thyssen's company Gewerkschaft Deutscher Kaiser or the Phönix AG für Bergbau und Hüttenbetrieb.
