In medical science the roll of eminent names is long and impressive, from Bannerman, who was physician to David II, down to Arthur Johnston, who after an academic career abroad, cultivated the muses at Aberdeen, gaining fame as a writer of Latin verse. He was for some time physician to Charles I. Born at Caskieben in 1587, he was rector of King’s College in 1637, and died in 1641. Dr John Arbuthnot, though a native of Kincardineshire, was a student at Marischal College; as the friend of Pope and Swift, and the wit and physician at the Court of Queen Anne, he is likely to be remembered. Another celebrated physician was Dr John Abercrombie, who, born in Aberdeen, went to Edinburgh, and became head of the profession and first physician to the king in 1824. Others no less noted were Sir James Clark; Sir Andrew Clark; Neil Arnott, a contemporary with Byron at the Grammar School, and more famous as natural philosopher than as physician, devising skilful inventions in healing and ventilation; Sir James Macgrigor, to whose memory a lofty obelisk in polished red granite was erected in Marischal College quadrangle. After standing there for years it was recently removed to the Duthie Park. Macgrigor was a pioneer in the humanitarian treatment of the sick and wounded in war, and was chief of the Medical Staff in the Peninsular campaigns. In natural science William Macgillivray is known by his careful and authoritative work on the _History of British Birds_. James Clerk Maxwell, who did so much for the advancement of modern Physics, was for a few years professor of Natural Philosophy in Marischal College. Dr Alexander Forsyth, minister of Belhelvie, invented the percussion lock, and Patrick Ferguson, a native of Pitfour, invented the breech-loading rifle. The county is remarkable for families with pronounced hereditary intellectual gifts. The most noted case is that of the Gregories, who sprang from John Gregory, minister of Drumoak. It has produced fourteen Professors in British universities, skilled in Mathematics, Astronomy, Chemistry and Medicine. One of them was the inventor of the reflecting telescope. The Reids, the Fordyces, the Johnstons are other cases less remarkable, but still exceptional.
