Oventrop (1820-1871) founds the "Arnold Oventrop & Co. Messing- und Broncewaarenfabrik zu
Altena" (bronze and brass works). From the start, the manufacturing programme
is founded on materials containing copper. Brassware, e.g. fittings for
furniture, doors and windows are produced. | | 1871 | The
company is passed on to the sons Friedrich Wilhelm (1847-1935) and Adolf Oventrop
(1851-1912). | 1886
1904 | The
town of Altena is by now highly industrialised. Employees are hard to find.
Therefore Oventrop sets up further production places in the "Sauerland" region (amongst
others in Iserlohn and Bigge). | | 1922 | The
son of Friedrich Wilhelm Oventrop, Paul Oventrop (1886-1974) takes over the
works in Bigge.
(The other works are gradually closed.) | | 1952 | The
families Fähnrich and Rump become partners of the company. The company is leading
in the field of oil products. | | 1973 | The
first oil crisis means drastic cutbacks after the "Economy Miracle" years. |
| 1975 | Due
to new municipal restructuring, Bigge becomes part of the town of Olsberg.
The company's head office is consequently Olsberg. | | 1980 | New
manufacturing premises are opened in Brilon. Thermostatic and other valves
and controls dominate the programme. | | 1990 | The
reunification of Germany and the opening of borders to the East contributes
to the company's strong growth. | | Today | Today
Altogether the company employs 800 people at their two facilities in Olsberg
and Brilon. The company has a varied portfolio of over 4,000 products for
heating, sanitary and industrial installations on offer. These products are
now sold in most countries throughout the world. | |
