Hugo Haehn

from Wikipedia, the free encyclopedia

Hugo Haehn (born September 26, 1880 in Herzberg / Elster ; † December 6, 1957 in Berlin ) was a German fermentation chemist and brewing scientist.

Life

Haehn studied chemistry, physics, mineralogy and physiology in Leipzig, Basel, Heidelberg and Munich. In 1904 he completed his dissertation in Heidelberg. He then worked at the chemical-pharmaceutical laboratory of the University of Königsberg until 1908, then until 1910 at the Agricultural University in Berlin and at the University of Breslau as a research assistant to Eduard Buchner . From 1910 to 1914 he worked on the development of biochemical processes; During the First World War he was partly in military service, partly at the Chemical Institute of the University of Veterinary Medicine Berlin , where he and Georg Schröter developed a technical process for the production of petroleum substitute ( tetralin ).

In 1918 Haehn was brought by Max Delbrück to the Institute for Fermentation Trade (IfGB), where he was entrusted with the management of the department for the investigation of biochemical processes. In more than 30 years of scientific work he contributed significantly to the elucidation of the discoloration of chopped potatoes, questions of citric acid and lactic acid fermentation , yeast utilization, the silage of agricultural products and the formation of diastases in molds. A theory about microbial fat synthesis from sugar is considered a special scientific achievement by Haehn. The realization that ethyl alcohol, when used correctly, is a means of fuel refinement, goes back essentially to the work of Haehn together with Friedrich Hayduck .
