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 1848 as a metal processing plant in Neheim-Hüsten, Germany 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 firm 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.
