Alternating company history

At the end of the second world war, the demand for panel displays for electric variables and portable voltmeters was very big in Switzerland. These were precisely the products with which Matter, Patocchi & Co. AG started in Wohlen in 1944. A little later, in 1947, Camille Bauer AG, a Basel trading company and Swiss sole representative of Hartmann & Braun products, bought the garage venture in Wohlen. In 1956, the company was renamed to Camille Bauer Messinstrumente AG.

The latter was acquired by the Mannheim Röchling group in 1979 and continued as an independent company within the group until 1991. After Gossen and Metrawatt had been acquired by Röchling the three enterprises were combined to the GMC Instruments group domiciled in Nürnberg in 1992. In 2005, the GMC group was sold to the Berlin capiton AG, a renowned investment company.

At the Wohlen site, the medium-sized company employs a staff of 90 in the areas of production, product development, marketing and international sales. In addition the GMC group operates its own national and international sales companies under the name of GMC Instruments.
