Wilhelm Thörner (born May 16, 1850 in Osnabrück ; † September 9, 1920 there ) was a German chemist .

Life

After graduating from the Ratsgymnasium Osnabrück , Thörner first made a commercial apprenticeship. In 1870 he took part in the Franco-German War as a dragoon and from 1871 studied natural sciences with a focus on chemistry in Bonn , Heidelberg and Göttingen . Academic teachers were August Kekulé (1829–1896) and Theodor Zincke (1843–1923). After receiving his doctorate in Göttingen, he worked as a lecture assistant in Marburg from 1877 to 1879 . Thörner founded an examination office for food and chemical-technical products in Osnabrück in 1880.

Scientific work

Thörner wrote a dissertation on "About some derivatives of Para-Tolylphenylketons". Together with Zincke he published studies on pinacones and pinacolins . In 1878 Thörner first described the mushroom ingredient atromentine . His other scientific work related to the topics of well hygiene, milk hygiene, metallurgical chemistry and radioactivity measurements. He improved the design of physical laboratory equipment. The manufacture of the first comparison microscope (1913) goes back to a design by Thörner. The unit of measurement for the acidity of milk is named after Thörner ( degree Thörner , ° Th).
