Ulrich Kreusler

Ulrich Kreusler (born November 4, 1844 in Arolsen , † October 18, 1921 in Bonn ) was a German agricultural chemist.

Life

Ulrich Kreusler studied natural sciences at the Georg-August University of Göttingen , where he received his doctorate in 1866 as a student of Friedrich Konrad Beilstein with a dissertation on paranitrotoluic acid . He then worked as a scientific assistant at several agricultural research stations. In 1873 he became head of the agricultural chemical research station in Poppelsdorf . As a lecturer, he also taught at the agricultural academy there. In 1880 he was appointed professor and in 1906 as the successor to Theodor Freiherr von der Goltz, director of the Agricultural Academy in Poppelsdorf. In 1887 he was elected a member of the Leopoldina . In 1918 he retired.

Kreusler wrote, among other things, a textbook on chemistry and an introduction to qualitative chemical analysis . For many years he edited Biedermann's Centralblatt for Agricultural Chemistry and Rational Farming , at that time the most important lecturing specialist body for scientifically oriented agricultural sciences . Kreusler developed numerous new analysis methods. The focus of his experimental research work included studies of the nitrogen and phosphate nutrition of grain and physiologically oriented experiments with potatoes .
