Cosack

The Gebrüder Cosack (Gecoscompany was founded in 1848 as a metal processing plant in Neheim-HüstenGermany by Egon, Friedrich and Theodor Cosack. In the beginning they made liturgical items and crosses made of brass and they also produced kerosene lamps. Later the company came to the production of electric lamps.

After the Second World War Cosack pursued a modern direction. A best seller were copper lighting for restaurants. The company was declared bankrupt in 1984.

Best known designers: Ursula or Gottfried Stürzenhofecker (unclear, they are both designers), K. H. Kinsky.  

Gebrüder Cosack (Gecos) received 15 iF Design Awards

Erwi

This lamp has a cast iron base made by Erwi. Erwi was a cast iron producer, not a lamp producer. The company made cast iron counterweights for several lighting companies. Erwi produced many items in cast iron, for instance also Christmas tree stands. In all probability a German company. The company no longer exists.

At least Kaiser Leuchten and Cosack Leuchten, both from Germany, used cast iron from Erwi for their lamps.
