John Floyer (physician)

Sir John Floyer (3 March 1649 – 1 February 1734) was an English physician and author.

John Floyer was born on 3 March 1649. He was the third child and second son of Elizabeth Babington and Richard Floyer, of Hints Hall, a since demolished country house. Hints is a quiet village lying a short distance from Lichfield in Staffordshire. He was educated at the University of Oxford.

He practised in Lichfield, and it was by his advice that Dr Johnson, when a child, was taken by his mother to be touched by Queen Anne for the king's evil on 30 March 1714. As a physician, Floyer was best known for introducing the practice of pulse rate measurement, and creating a special watch for this purpose. He was an advocate of cold bathing, and gave an early account of the pathological changes in the lungs associated with emphysema.

Floyer was married to Mary Fleetwood of Lichfield, a widow, in April 1680. Their son John Floyer (c.1681–1762) was a Tory Member of Parliament for Tamworth from 1741 to 1742.

He died on 1 February 1734.
