Herbert Hope Risley

Sir Herbert Hope Risley was a British ethnographer and colonial administrator, a member of the Indian Civil Service who conducted extensive studies on the tribes and castes of the Bengal Presidency. He is notable for the formal identification of the centuries old established caste system of the entire Hindu population of British India in the 1901 census, of which he was in charge. As an exponent of scientific racism, he used anthropometric data to divide Indians into seven races.
