Shaw was the son of Robert Shaw, A.M., master of the grammar school at Lichfield. After passing some years of professional life at Scarborough, he was practising physic in London in 1726, apparently without a degree or the licence of the Royal College of Physicians, but did not permanently settle there until some years later. On 25 June 1740 he was admitted a licentiate of the College of Physicians, being then a doctor of medicine, but of what university is not recorded. In London he attained popularity as a physician. He was patronised by Sir Edward Hulse, one of the court physicians, at that point gradually withdrawing from practice. He was admitted a candidate at the College of Physicians on 16 April 1753, and was made a fellow on 8 April of the following year. In 1752 he was appointed physician-extraordinary to George II, and the same year was created doctor of medicine at Cambridge by royal mandate. Two years later he was promoted to be physician-in-ordinary to the king, and he was the usual medical attendant on George II in his journeys to Hanover. He was nominated to the same office on the accession of George III. He died on 15 March 1763, aged 69 years, and was buried in the nave of Wimbledon church, where there was an inscription to his memory.
Works
He contributed to the study of chemistry in England by his translations of the works of Georg Ernst Stahl and Herman Boerhaave, as well as his own writings and lectures. Shaw was prolific if careless. He was editor of the works of Francis Bacon and Robert Boyle. Shaw's translations or adaptations included:
