The German chemist and viticulturist Dr. Leonhard Roesler (1839-1910) studied chemistry in Erlangen and Göttingen. From 1867 onwards he was a full professor at the Grand Ducal Baden Technical University in Karlsruhe (Baden-Württemberg). Here he was already primarily concerned with questions of wine chemistry. During this time he published the "Annalen der Oenologie" (Annals of Oenology) together with his colleague Dr. Adolph Blankenhorn (1843-1906). In 1870 he was entrusted with the management of the newly established Oenochemical Experimental Station at the Klosterneuburger Wein bauinstitut (Lower Austria), which at that time was independent of the viticultural school headed by Baron August-Wilhelm Babo (1827-1894).
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
