Langenthal

Carrosserie Langenthal AG (Calag) is a Swiss coachbuilder in Langenthal, canton of Bern, that grew from a wainwright workshop founded in 1888. It became known around 1930 for car bodies, above all the Langenthaler Cabriolet, and later turned mainly to commercial-vehicle bodywork.1

History

The firm began in 1888 as a wainwright workshop run by Fritz Grogg in Langenthal and moved premises twice before 1894. In 1926 it became a partnership under the Grogg family and Sommer, and in 1929 it was turned into the family company Carrosserie Langenthal AG with new land on Aarwangenstrasse. Around 1930-31 a new workshop hall was built, and the company says Langenthal became known for car bodies, especially the Langenthaler Cabriolet. In 1937 it leased the Geissberger coachworks in Zurich, and from the 1940s it also cooperated on tipper bodies. It has been under new ownership since 1970 and 2004 and today trades as Calag, concentrating on commercial vehicles.
