Thomas Percival

Thomas Percival (29 September 1740 – 30 August 1804) was an English physician, health reformer, ethicist and author who wrote an early code of medical ethics. He drew up a pamphlet with the code in 1794 and wrote an expanded version in 1803, Medical Ethics; or, a Code of Institutes and Precepts, Adapted to the Professional Conduct of Physicians and Surgeons in which he coined the expression "medical ethics". He was a founding subscriber of the Portico Library in Manchester and a pioneering campaigner for public health measures and factory regulation in the city.
