James De Ville
His grandfather was from Bern, Switzerland but emigrated to England along with other Protestants perhaps in the 1740s. De Ville's mother and maternal grandmother were English. Because his family fell into hard times De Ville was raised from the age of eight by a maternal uncle who had a brickmaking business in Hammersmith.
De Ville was the most prominent practical phrenologist, supplier and maker of phrenological casts in London from the 1820s to the 1840s. By 1826 Johann Spurzheim declared that De Ville's collection was the finest he had ever seen. Franz Joseph Gall himself also highly valued De Ville's work and sent a wax mould of a dissected brain as a token of respect. De Ville's casts were distributed throughout the world and many still survive in the collection of the Edinburgh School of Anatomy.
In 1840 he became a member of the Phrenological Association and resigned in 1842 upon the occasion of the great split among British phrenologists when William Collins Engledue (1813–1858), in a speech before the Association, announced that phrenology and materialism were the same.
De Ville examined an enormous number of heads including those of many well-known figures including John Elliotson, Hermann Prince of Pückler-Muskau, William de Salis, Harriet Martineau, Charles Bray, George Eliot, William Blake, Richard Dale Owen, Richard Carlile, the Duke of Wellington and Prince Albert.
