By the early 20th century, Ripley's tripartite Nordic/Alpine/Mediterranean model was well established. Most 19th century race-theorists like Arthur de Gobineau, Otto Ammon, Georges Vacher de Lapouge and Houston Stewart Chamberlain preferred to speak of "Aryans," "Teutons," and "Indo-Europeans" instead of "Nordic Race". The British-born German racialist Houston Stewart Chamberlain considered the Nordic race to be made up of Celtic and Germanic peoples, as well as some Slavs. Chamberlain called those people "Celt-Germanic peoples", and his ideas would influence the ideology of Nordicism and Nazism.
