James Cowles Prichard was born on 11 February 1786, into a Quaker family in Herefordshire, and died in London on 21 August 1848. In 1808 he took his MD degree at Edinburgh University. Motivated not least by the lectures of Dugald Stewart, he chose the varieties of mankind as the subject of his MD dissertation. In 1810 he converted to the Church of England and, later that year, set up in private practice in Bristol, launching into a successful career as physician and alienist. His political views, as well as his medicine, were conservative. He was exceedingly devout, his faith falling in with contemporary evangelicalism, which also influenced his scholarship.
