Georg (Richard) Gehlhoff (born February 7, 1882 in Adlig Rauden, Marienwerder district , West Prussia ; † March 12, 1931 in Sierre , canton of Valais ) was a German physicist.
He studied physics at the Technical University of Danzig and the University of Berlin , where he received his doctorate in 1907 under Emil Warburg . He became assistant to Heinrich Rubens and in 1911 to Jonathan Zenneck in Danzig, where he also completed his habilitation . During this time he made studies of electrical discharges ( corona discharge ) and the thermal conductivity of antimony - bismuth - alloys and mercury .
In 1913 he started at the optical institute CP Goerz as a research assistant for the construction of optical instruments and was promoted to authorized signatory until 1917. He also became head of the headlight factory in Leutzsch, which Goerz had taken over . Here he was interested in technical optics and lighting technology, especially electric arcs and headlight technology. In 1920 he became director of the acquired Sendlinger Optische Glaswerke GmbH in Berlin-Zehlendorf. This was the former Steinheilschen experimental glassworks relocated from Munich to Berlin.
In 1922 he joined Osram GmbH in Berlin , where he was appointed director of the Weißwasser / Oberlausitz glassworks and later of the machine glassworks in Berlin-Siemensstadt . He transferred the glass research that was in its infancy to a scientific study. In the glass laboratory he set up, the physical properties of glass in the solid and liquid state were systematically researched. He also worked in the field of refractory clays and stones.
Gehlhoff was an honorary doctorate from the Technical University of Dresden .
