Vtg Round Lufft Desk Hygrometer Brass Lu? Ftfeuchte (humidity) Germany – Works! The company is still around….. He had the task to prepare scientific experiments and build up and maintain the instruments as well as the facilities. In 1873, when he was 25 years old, he took over the well-established optics business SF Trostel in the Eberhardstrasse 37, in Stuttgart. Here, he started with the production of aneroid capsules in the very same year. From the exemplary documentation of the Lufft house, it is evident, that these membrane capsules were known in Germany in the beginning 70’s in Germany already but obviously needed to be imported from France. It became a market which was administered by G. Lufft very successfully, at the beginning in his optics production workshop, from 1881 on in the newly founded mech. There, aneroid barometers, compasses, hygrometers and further meteorological instruments were produced.
