The German winegrower Dr. Georg Zimmermann (1907-1993) was born the son of a winemaker in Rheinhessen. He studied agriculture and did his doctorate in 1934 with a thesis on "A contribution to the exact experimentation in viticulture". At the Kaiser Wilhelm Institute, he received from Dr. Erwin Baur
(1875-1933) a first insight into breeding research. In his dissertation, he was later made friends by Georg Shy
(1879-1949) in the Alzey Vine Breeding Institute. After his death, he was appointed head of Alzey grape breeding in 1950. He continued the suitability tests for the varieties created by Scheu and submitted their approval to the Federal Plant Variety Office. The focus of his work also included the quantity-quality ratio and behavioral research. Zimmermann defined the goal of vine breeding that water and sugar could be dispensed with in winemaking. In the 1960s, he advocated the adoption of the French appeals regime. Zimmermann gave numerous lectures and wrote many publications on the subjects of viticulture, vine-growing and cellar management.
