Although the German eugenics movement, led until the Weimar years by Alfred Ploetz and Wilhelm Schallmayer, did not differ radically from the American movement, it was more centralized. Unlike in the United States, where federalism and political heterogeneity encouraged diversity even with a single movement, in Germany one society, the German Society for Race Hygiene (Deutsche Gesellschaft fue Rassenhygiene), eventually represented all eugenicists, while one journal, the Archiv für Rassen- und Gsellschafts Biologie, founded by Ploetz in 1904, remained the primary scientific publication of German Eugenics.
↑ In 1876 Haeckel had discussed the selective infanticide policy of the Greek city of ancient Sparta.Haeckel, Ernst (1876). “The History of Creation, vol. I”. New York: D. Appleton. tr. 170. Among the Spartans all newly born children were subject to a careful examination or selection. All those that were weak, sickly, or affected with any bodily infirmity, were killed. Only the perfectly healthy and strong children were allowed to live, and they alone afterwards propagated the race.
