Andrew Halliday

Biography He was born in Copeland, Dryfesdale in Dumfriesshire.

When he was nine years old, Halliday had to earn his own living by tending cattle because of his father's financial problems. He later advanced himself by qualifying as a schoolteacher.

He was later the domestic physician to the Duke of Clarence and St Andrews (who became William IV), and traveled on the continent with him. In 1817, he was made a licentiate of the Royal College of Physicians of Edinburgh and, in 1819, of the Royal College of Physicians, London. While traveling on the continent, he became familiar with the medical applications of iodine, introducing it to Britain upon his return in 1819 and publishing an article on it in 1821. He was appointed a Knight of the Royal Guelphic Order in 1820 and a Knight Bachelor in 1821. In August 1827 he was elected a fellow of the Royal College of Physicians of Edinburgh.
