  Works such as Arthur de Gobineau 's An Essay on the Inequality of the Human Races (1853–1855) may be considered one of the first theorizations of this new racism, founded on an essentialist notion of race, which opposed the former racial discourse, of Boulainvilliers for example, which saw in races a fundamentally historical reality, which changed over time. Gobineau, thus, attempted to frame racism within the terms of biological differences among humans, giving it the legitimacy of biology.
  
  Gobineau's theories would be expanded in France by Georges Vacher de Lapouge (1854–1936)'s typology of races, who published in 1899 The Aryan and his Social Role, in which he claimed that the white " Aryan race" " dolichocephalic ", was opposed to the "brachycephalic" race, of whom the " Jew " was the archetype. Vacher de Lapouge thus created a hierarchical classification of races, in which he identified the " Homo europaeus (Teutonic, Protestant, etc.), the " Homo alpinus " (Auvergnat, Turkish, etc.), and finally the " Homo mediterraneus " (Neapolitan, Andalus, etc.) He assimilated races and social classes, considering that the French upper class was a representation of the Homo europaeus, while the lower class represented the Homo alpinus. Applying Galton's eugenics to his theory of races, Vacher de Lapouge's "selectionism" aimed first at achieving the annihilation of trade unionists, considered to be a "degenerate"; second, creating types of man each destined to one end, in order to prevent any contestation of labour conditions. His "anthroposociology" thus aimed at blocking social conflict by establishing a fixed, hierarchical social order.
  
  The same year, William Z. Ripley used identical racial classification in The Races of Europe (1899), which would have a great influence in the United States. Other scientific authors include H.S. Chamberlain at the end of the 19th century (a British citizen who naturalized himself as German because of his admiration for the "Aryan race") and Madison Grant, a eugenicist and author of The Passing of the Great Race (1916). Madison Grant provided statistics for the Immigration Act of 1924, which severely restricted immigration of Jews, Slavs, and Southern Europeans, who were subsequently hindered in seeking to escape Nazi Germany.
