HISTORY
Oscar Miller is a Bavarian entrepreneur who ordered a planetarium from Zeiss for his Deutsches Museum around 1913. After the First World War, research resumed and it was in 1923 that a first model made trips back and forth between the Jena factory and Munich (see: "The Beginning")
2 copies of model 1 will be developped and 25 copies of the model II before the WWII.
After WWII, Zeiss was divided into two independent parts (each offering Zeiss projectors):
- Jena in East Germany (GDR), 1948
- Oberkochen in West Germany (FRG), 1946.
During the great reunification of Germany (1990-92), the two companies merged again.
