Aryan race
Max Müller is often identified as the first writer to mention an "Aryan race" in English. In his "Lectures on the Science of Language" (1861), Müller referred to Aryans as a "race of people". At the time, the term "race" had the meaning of "a group of tribes or peoples, an ethnic group". He occasionally used the term "Aryan race" afterwards, but wrote in 1888 that "an ethnologist who speaks of Aryan race, Aryan blood, Aryan eyes and hair, is as great a sinner as a linguist who speaks of a dolichocephalic dictionary or a brachycephalic grammar".
