Knighton, William (1776–1836)
Courtier and physician. He became a friend of Henry Herbert Southey while the two men were studying medicine at the University of Edinburgh, and set up a London practice in 1806. He was appointed physician to the Prince of Wales (the future George IV) in 1810 and gradually assumed the role of sorting out the Prince’s tangled finances. In 1822 he became Keeper of the Privy Purse and, effectively, George IV’s private secretary. Knighton furthered Henry Herbert’s career, ensuring he succeeded him as physician to George IV in 1823. Knighton also aided Robert Southey by presenting A Vision of Judgement (1821) to George IV.
