The German biologist and agronomist Professor Dr. Dr. Bernhard Husfeld (1900-1970) studied at the Berlin Agricultural University. In 1923 he became assistant to Dr. Erwin Baur (1875-1933) at the latter's Institute of Heredity Research. Baur assigned him the task of translating the findings of heredity theory into vine breeding. In 1928 Baur founded the Department of Grapevine Breeding in Müncheberg (Mark Brandenburg) as a branch of the Kaiser Wilhelm Institute for Breeding Research (KWI). Baur introduced resistance breeding and entrusted his assistant with this task. Husfeld received his doctorate in 1932 with a thesis on the breeding of plasmopararesistant vines (downy mildew). After Baur's death, Husfeld became interim head of the institute in 1933 and, after the appointment of Dr. Wilhelm Rudorf (1891-1969) in 1936, his deputy. He initiated an extensive breeding programme with the aim of creating an "ideal vine".
