The German wine grower Dr. Georg Zimmermann (1907-1993) was born the son of a winemaker in Rheinhessen. He studied agriculture and obtained his doctorate in 1934 with a thesis on "A contribution to the exact experimentation in viticulture". At the Kaiser Wilhelm Institute he received Erwin Baur
(1875-1933) a first insight into the breeding research. In his dissertation he was later friends with him Georg Shy
(1879-1949) in the grapevine breeding establishment Alzey. After his death he was appointed in 1950 to head the Alzeyer vine breeding. He passed on the aptitude tests of the many varieties created by Scheu and submitted their approval to the Bundessortenamt. His work also focused on the quantity-quality relationship and behavioral research. Zimmermann defined as the goal of vine breeding that can be dispensed with the winemaking on water and sugar. In the 1960s, he pleaded for the acquisition of the French appellation scheme. Zimmermann gave numerous lectures and wrote many publications on the topics viticulture, vine growing and cellar management.
