Establishment of the forge in Teningen
There are reports of an old forge at the same site even before 1771. However, the establishment of a new forge workshop by Jakob Zimmermann in 1771 is considered the birth of the site. The development of the Teningen industrial site today can be traced back to this point. Zimmerman produced devices required for agriculture and forestry as well as viticulture in his forge. This included axes, spades and hatchets. The "Z" with which he marked his tools became a quality mark and enjoyed an excellent reputation until forge operations were shut down in the 1950s.
