John Micklethwaite was the son of Thomas Micklethwaite, rector of Cherry Burton, Yorkshire, and was baptised, 23 August 1612, in the church of Bishop Burton, three miles from Beverley.
He was elected a fellow of the College of Physicians 11 November 1643, and delivered the Gulstonian lectures in 1644.
[1] When Charles II in 1681 was taken ill at Windsor, Micklethwaite was sent for by Order in Council, and attained much repute by his treatment of the king, on whose recovery he was knighted.
He died of acute cystitis 29 July 1682, and was buried in the church of St. Botolph, Aldersgate, where his monument, with a long inscription, still remains.
His portrait, representing him in a flowing wig, was given to the College of Physicians by Sir Edmund King, and hung in the dining-room.
