Kern AarauThe until 1992 under the name Kern & Co AG, Aarau, known company was founded in 1819 by Jakob Kern in Aarau.1 Kern learned in Aarau the profession of instrument maker, went to Munich - one of the former centres of optical research and construction of fine mechanical instruments - and opened his own workshop after his return in Aarau.
In the 19th Century, the company grew steadily, but the period after the First World War led to business troubles; economic crisis, poor utilization of the newly started optics fabrication and especially the competition from new surveying instruments produced by Heinrich Wild Heerbrugg. In 1857 Jakob Kern retires from the company.
In 1937, as a blessing in disguise, Heinrich Wild resigned in Heerbrugg and agreed to cooperate with Kern. With this Kern was able to secure its market presence.
After the Second World War they managed a technical and commercial breakthrough thanks to the lenses for the Bolex cine cameras of the Paillard company. It was considered whether or not the construction of surveying instruments had to be continued at all.
An in 1958 completed reorganization of Kern decreased the emerging dangerous dependence as a supplier for a single company, and strengthened the field of surveying, which was significantly enhanced by the inclusion of photogrammetry. With the reorganization the previously neglected operational division into four management areas (designated departments) was gradually further developed.
When in 1963 the sale of film lenses collapsed for Paillard, they were glad to be able to continue to support surveying instruments. The photogrammetry division too recorded a success with the PG2.
The management in the jubilee year 1969:
At the end of the 1970s the electronic theodolite E-series (E1, E2, E12, E2-ST) were added. Equipment that would play an important role for the emerging sector of industrial surveys. In 1988, the new version of the electronic theodolite, the E10, was ready. It however never came into production due to the sale of the company on 13 May 1988 to the Wild Leitz group.
In 1991 the production facilities of the company Kern & Co. AG were closed in Aarau.
