Physicians to the Duke of Clarence.

: Halliday and Beattie came from the small village of Dalton in Dumfriesshire and both became physicians to the Duke of Clarence, the King's brother. They had interesting and varied careers and accompanied their royal patron on his frequent visits to the Continent. Halliday served in the Peninsula War and at Waterloo while Beattie became a close friend and confident of the Duke. Based on his visits to the Continent, Beattie produced a beautifully illustrated series of travel books.
