The study of eugenics had its beginning in Germany, sometime after the mid-19th century mark, stimulated by volkish concerns for Aryan racial purity. Rudolf Virchow, pathologist and politician, began a study of national ethnic statistics in 1871, convinced that the majority of Germans would prove to be of relatively pure Nordic descent. The results of his studies proved otherwise. According to Virchow, the obvious solution was to set about Nordicizing the debased German stock.
