Life and museum work
Deniker was born in Astrakhan on 6 March 1852. He trained in chemistry at the Technological Institute in St Petersburg and travelled in Transcaucasia and Persia to study petroleum deposits. After further scientific study in western Europe, he settled in Paris in 1876.
He studied botany, zoology and geology at the Sorbonne and the natural history museum. In 1886 he received his doctorate in natural sciences for research on the anatomy and embryology of anthropoid apes. Two years later he became chief librarian of the Muséum national d’histoire naturelle, remaining there until his death.
The Association des bibliothécaires français credits him with creating the museum library’s alphabetical card catalogue. He helped establish the association and was its first president, from 1906 to 1908. He also worked on bibliographies of French learned societies and the Dictionnaire de géographie universelle. Deniker died in Paris on 18 March 1918.
Anthropology
His Les Races et les peuples de la terre appeared in 1900, with a revised edition published posthumously in 1926. Deniker sought to classify people through bodily measurements and visible physical characteristics. In an 1889 paper he distinguished communities formed through language, religion and social institutions from the physical types he called races. He considered existing populations to be mixtures and tried to identify their constituent types.
This distinction remained part of a racial classification scheme. It did not replace that scheme with a purely cultural account of human differences. Such divisions are not an accurate account of human biology: the American Association of Biological Anthropologists’ statement on race explains that human variation does not fall into fixed racial groups.
