Other versions: This Cosack broken glass wall lamp was made in several colours and sizes.
Probably inspired by a design by Willem van Oyen Sr. for Raak Amsterdam: the Chartres wall lamp. Several light companies in Europe produced their version of the Chartres lamps.
The style of these type of lamps is often named Brutalist. Not to be confused with the Brutalist architecture, or Brutalism from more or less the same period. That’s something completely different.
The Gebrüder Cosack (Gecos) company was founded in 1833 as a metal processing plant in Neheim-Hüsten, Germany by Egon, Friedrich and Theodor Cosack together with Gottliebe Tappe. It was named Metallwarenfabrik Tapp + Cosack. In the beginning they made liturgical items, crosses and upholstery nails made of brass and they also produced kerosene lamps. Later the company came to the production of electric lamps.
In 1921 a cardboard factory was started, originally for packaging the Cosack Group‘s own products, including lights, nails, rivets and kitchen appliances.
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.
The cardboard factory still exists. The sixth generation is now running the business at the Cosack plant.
Best known designers: Gottfried Stürzenhofecker, K. H. Kinsky, Hans Wilfried Hegger, Hans-Joachim Groth, Burkhard Panteleit, Joachim O. Becker, Prof. Friedrich Becker, Waldemar Rothe and Jan Armgardt.
