Hindenburg light
The Hindenburg light or Hindenburglicht was a source of tallow lighting used in the trenches of the First World War, named after the Commander-in-Chief of the Imperial [German Army in World War I|German army] in World War I, Paul von Hindenburg. It was a flat bowl approximately in diameter and deep, resembling the cover of Mason jar lid and made from pasteboard. This flat bowl was filled with a wax-like fat. A short wick in the center was lit and burned for some hours. A later model of the Hindenburglicht was a "tin can lamp." Here, a wax-filled tin can have two wicks in a holder. If both wicks are lit, a common, broad flame results.
The lights were also used in World War II in air raid shelters or during power cuts, and mandated black outs as emergency lighting.
The Hindenburg light is mentioned in the novels, "Die Entdeckung der Currywurst" by Uwe Timm and Berlin by Theodore Plievier, as used on the Eastern Front and in air raid shelters respectively. Also it is mentioned in Wheels of Terror by Sven Hassel and In Deadly Combat: A German Soldier's Memoir of the Eastern Front by Gottlob Herbert Biedermann.
