Both products are tightly connected to the VEB Carl Zeiss Jena. After the riots of the 17th of June 1953 the party leaders decided to increase the production of high value consumer goods to keep up with West-German standards. Carl Zeiss Jena commited itself to develop a middle class camera and produce it in large figures to fulfill the demand of the GDR population. For that purpose Zeiss Jena incorporated an existing factory in Eisfeld and modernized it in order to produce that camera called "Werra". Just about the same thing happened with the VEB Feingerätewerk Weimar, which was founded on the 1st of July 1950 and was incorporated into Zeiss Jena by about 1953 to produce light meters and subminiature film projectors.
The "Werralux" was first shown on Leipzig Spring Fair 1956 (cp. Bild und Ton, 4/56, p. 97) and produced in various designs during the following years. The name "WERRAlux" indicates that originally it was meant as an affordable exposure meter for the first version Werra camera. This assumption gets it's logic explanation by the fact that Eisfeld - where the camera was made - lies at the river WERRA, Weimar - where the light meter was made - does not. But this light meter was of course also bought by owners of other cameras. So in spring 1960 the "Werralux" was replaced by a more advanced model (cp. Bild und Ton, 3/60, p. 88). Casually the name was changed to "Weimarlux", which finally refered more to its producer. Meanwhile the Feingerätewerk Weimar had left Carl Zeiss Jena and later became part of the enormous watch making enterprise VEB Uhrenkombinat Ruhla. But they kept making Weimarlux hand meters until the last days of GDR.
