history

The company was founded in 1911 in Frankfurt am Main , Rebstöcker Straße 55, by the brothers John J. Schneider († 1951), Carl August Schneider and chief engineer Rudolf Naujoks and until Naujoks' departure in 1914 under the name of Dr.-Ing. Schneider & Naujoks Elektrizitätsgesellschaft mbH .

Around 1916, the company provided a questionnaire for planning lighting projects. A sales branch was set up in Berlin, around 1920 a sales office in Essen and a production branch in Usingen . Was produced u. a. Spotlight with enamel reflector and, from approx. 1937, blackout lamps (black-lacquered opal glass bell with light outlet opening downwards).

The company employed forced laborers during the Second World War . For the year 1943, 25 Russians, 16 Ukrainians and two German men are documented in Lahnstrasse 19 in Frankfurt (43 people).

In 1951 the son-in-law Fritz Kalberlah († 1979) took over the management. Half of the annual turnover of almost DM 12 million was generated from the hospital technology business area.
