Heinrich Fincke

from Wikipedia, the free encyclopedia

Heinrich Wilhelm Christian Fincke (born June 30, 1879 in Neuss am Rhein; † July 24, 1965 in Cologne ) was a German chemist and food chemist who was best known for his contributions on cocoa , cocoa products and confectionery .


Fincke left the Paulinisches Gymnasium in Münster in 1895 with the "one-year" degree . He then completed an apprenticeship as a pharmacist in Radevormwald. From 1901 Fincke studied pharmacy and food chemistry at the University of Münster. He passed the exams in both subjects with "Very Good". At the same time, Fincke was an assistant at the agricultural research institute in Münster with Joseph König , the founder of food chemistry in Germany. During this time he presented his first publications on the "seeds of Parkia africana and the Daua-Daua cheese made from them" and "on the cellulose, lignin and cutin content of pepper and cocoa". Fincke then went to Rostock to study chemistry at the University of Rostock . After taking the association examination , he received his doctorate in Rostock in 1909 with a thesis on stereometry in derivatives of diphenylethylene. Fincke later worked at the Cologne Food and Research Institute, where he published works on pyridine in ice cream and formic acid in food.

He later headed the laboratory of the Stollwerck cocoa and sugar goods factory in Cologne, where he improved and created numerous test methods for food. This is how he found the first precise and easily carried out determination of lactose . At Stollwerck, Fincke became the leading cocoa expert: in 1929 he published a book on cocoa butter and its adulterations and in 1936 the handbook of cocoa products, which achieved "worldwide recognition". This manual was reissued and revised in 1965 with the assistance of his son Albrecht Fincke .

Fincke has presented a total of more than 500 publications, in addition to chemical-analytical research, also works on the structure and composition of food and the origin of food law terms.

In 1944 he received the Joseph König commemorative coin from the Society of German Chemists.

Fincke was married to Wilhelmine Elisabeth Janzen from 1922. He died in 1965 at the age of 86 in a Cologne hospital.
