Theodor Henkel
Theodor Ludwig Henkel (born September 17, 1855 in Wolfertschwenden ; † February 2, 1934 in Freising ) was a German pioneer in milk science.
Life
The son of the Munich master saddler Theodor Henkel (1811–1874) and Therese, b. Ebersberger (* 1814), joined the upper class of the Maximiliansgymnasium in Munich in the school year 1873/74 from the high school in Dillingen , where he graduated from high school in 1874. He then studied natural sciences ( chemistry ) at the Polytechnic in Munich and joined the later Corps Ratisbonia in 1876 . a. Franz von Soxhlet became aware of him in the agricultural chemistry laboratory and in 1880 gave him an assistant position.
In 1884, Henkel took over the management of the dairy product factory from Eduard Loefflund in Schüttentobel in the Allgäu, where it developed the production of sterilized and condensed milk without sugar and canned cream. From experiments on animal feeding and the acidification process in milk, Soxhlet and Henkel developed the process of titrimetric determination of the acidity of milk, which is internationally recognized and still common today. In 1888 he discovered the citric acid contained in milk and received his doctorate on this subject from the University of Erlangen in 1891 . In 1902 he was offered a position at the Technical University of Munich and the Academy for Agriculture and Brewery in Weihenstephan near Freising, where he expanded dairy farming to become an independent subject. Germany’s rapid industrialization called for “milk hygiene”.
In 1913, Henkel succeeded his teacher and mentor von Soxhlet at the Technical University of Munich and kept the management of the institute until 1919. In 1925 he became a go. Government councilor appointed and entrusted with the management of the Bavarian main research institute for agriculture. He was honored to be retired in 1934 . He has received numerous awards for his scientific achievements, including the King Ludwig Cross , the Liebig Prize, the large silver Max Eyth Medal of the German Agricultural Society and the Dr. [Franz Josef] Heart Medal.
Henkel married Rosalie Graf (1859–1915), daughter of the sculptor Johann Evangelist Graf (* 1826) in Munich in 1885. The marriage resulted in the sons Theodor (* 1890) and Heinz (* 1893; fallen in 1916) as well as the daughter Helene (* 1891).
