The German biologist and oenologist Dr. Carl Julius Bernhard Börner (1880-1953) studied biology in Marburg (Hessen). From 1903 he was an assistant at the Kaiserliche Biologische Anstalt (later Biologische Reichsanstalt) in Berlin. As head of the vine station Ulmenweiler near Metz (Lorraine) from 1907, he devoted himself to research into the biology and control of phylloxera. In 1910, he discovered species of this pest that differed by the length of the trunk. After relocating the vine station to Naumburg (Saale), he bred phylloxera-resistant rootstocks there and successfully fought for the introduction of grafting (graft-vine cultivation) in Germany. Furthermore, he worked on the phylloxera laws and the control of German wine-growing areas contaminated by the pest. In 1935 he succeeded in discovering a completely phylloxera-resistant American wild vine of the Vitis cinerea Arnold species (see Nodosities and Tuberosities). Based on this vine, Dr. Helmut Becker (1927-1990) bred a rootstock which he named in honour of the discoverer. Börner also rendered outstanding services in the research of aphids.
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.Egon Mark
