Gutehoffnungshütte, Aktienverein für Bergbau und Hüttenbetrieb (GHH for short) was one of the largest mining and engineering companies in the Ruhr region, based in Oberhausen, with a history dating back to the eighteenth century. During the industrialization of Germany in the nineteenth century, the company played an important role by manufacturing steam engines and locomotives, railroad tracks, and bridges, among other things. From the nineteenth until well into the twentieth century, the Haniel family held the majority of the company’s shares. This documentary film from 1917, produced by the Deutsche Lichtbild-Gesellschaft (Deulig), shows the GHH iron foundry, blast furnaces, and steelworks, giving an impression of the enormous productivity of Germany’s heavy industry at a time when it was the backbone of the war economy. Deulig was founded in 1916 on the initiative of industrialists from the Rhineland, notably the Krupp magnate and ultra-nationalist Alfred Hugenberg. The goal of Deulig, as part of the larger turn towards wartime propaganda in late 1916, was to produce films that would showcase the capacity and power of German industry, both domestically and in neutral countries. Note the vast scope of the industrial area; in 1917, the GHH had over 40,000 employees. The large number of smokestacks (venting the coal-fired machinery) are clearly impacting air quality, with the century-old church in the background barely visible through the smoke. Note also the lack of safety features (such as exposed piston arms and a lack of guardrails): industrial accidents that maimed or killed were very frequent.
