Hermann Chr. Langerhans (1754-1839), born in Bendorf on the Rhine, was a member of the famous Neuwieder clock manufacture. He was taught the craft of clock making by Peter Kinzing (1745-1816) and produced among other things outstanding astronomical clocks. By collaborating with the cabinetmakers Abraham (1711-1793) and David (1743-1807) Roentgen the clocks from Neuwied became famous throughout Europe; today they can be found in major collections worldwide. Langerhans worked as a watchmaker in Krefeld and according to Nemnich, he built music boxes of various kinds and outstanding astronomical clocks. In fact, a musical clock in a Roentgen case made by him has been preserved. It was owned by the Cologne municipal museum. In addition, there is an equation clock of Langerhans in a private collection, comparable with the precision pendulum clock, which Roentgen gave to the city of Leipzig in 1797.
