Johann Großfeld

Johann Gerhard Großfeld (born February 25, 1889 in Bad Bentheim , † June 3, 1944 in Munich , often abbreviated as J. Großfeld ) was a German food chemist.

Großfeld attended high school in Rheine and studied chemistry in Freiburg, Munich and finally in Münster, where he received his doctorate in 1913 under Joseph König and also passed the "state examination for food chemists". He then worked at the Chemical Investigation Office in Recklinghausen from 1914 to 1927 . From this investigative office he was appointed group leader at the Prussian State Food Research Institute in Berlin-Charlottenburg, which was headed by Adolf Juckenack . The Berlin research institute was later renamed the Reich Institute for Food and Drug Chemistry . Großfeld was a scientific advisor and professor at the Reichsanstalt, where he worked until his death.

Großfeld has dealt particularly with the analysis of fats and oils. He also wrote numerous contributions to the "Handbuch der Lebensmittelchemie", of which he was one of the editors from 1939 to 1942.

From volume 72 (1936) he was editor of the magazine for food analysis , the later magazine for food analysis and research (ZLUF).

Großfeld was married. He suffered from a kidney disease and was in Bad Tölz for treatment; he died in a clinic in Munich and was buried in the forest cemetery in Berlin-Dahlem.
