Founded in Paderborn, Germany, in 1904, Doch & Ziemlich was established by Dr. Joachim Doch and Wilhelm Ziemlich. The partnership combined Doch’s background in theoretical physics with Ziemlich’s expertise in mechanical clockmaking to develop early industrial instrumentation.

In 1908, the company engineered and patented the Doch-Ziemlich Etherometer, which became a baseline diagnostic safety standard across the Ruhr Valley rail network.

Today, Doch & Ziemlich operates as a specialized research institution. The firm’s primary focus is the development of Kinetic Resonator Calibration, a proprietary method used to eliminate microscopic structural vibrations in high-stress industrial alloys.
