Swedish botanist and physician who developed the system for sorting living organisms into major (genus) and then more specific (species) categories (e.g. Homo sapiens). In the 1758 tenth edition of Systema nature (Natural System), Linnaeus created the first formal, non-scientific human racial classification scheme. It included five varieties of Homo sapiens “Americanus,” “Europaeus,” “Asiaticus,” “Afer,” and “Ferus” based on physical and cultural descriptions that favored Europeans. Linnaeus’ human classification system influenced the way race is conceptualized in the US. See also Blumenbach, Johann Friedrich.
