Percivall Pott (6 January 1714, in London – 22 December 1788) was an English surgeon, one of the founders of orthopaedics, and the first scientist to demonstrate that cancer may be caused by an environmental carcinogen, namely chimney sweeps' carcinoma. Many diseases are his namesake including Pott's fracture, Pott's disease of the spine, and Pott's puffy tumour. It is believed that Pott's standard of living contributed to the rise of the surgeon within social standings.
Percivall Pott was born the son of Percivall Pott senior in London. His father died when he was a child, but Joseph Wilcocks, Bishop of Rochester, who was a relative of his mother, paid for his education. He served his apprenticeship with Edward Nourse, assistant surgeon to St Bartholomew's Hospital, and in 1736 was admitted to the Barbers' Company and licensed to practice.
He became assistant surgeon to St Bartholomew's in 1744 and full surgeon from 1749 till 1787.
As the first surgeon of his day in England, excelling even his pupil, John Hunter, on the practical side, Pott introduced various important innovations in procedure, doing much to abolish the extensive use of escharotics and the cautery that was prevalent when he began his career.
In 1756, Pott sustained a broken leg after a fall from his horse. It is often assumed that his injury was the same one that later came to be known as Pott's fracture, but in reality, Pott's broken leg was a much more serious compound fracture of the tibia. As he lay on the ground, he sent a servant to buy a door from a nearby construction site, then had himself placed on the door and taken home. Surgeons cleaned the wound and discussed amputation, an operation which at the time had a very high rate of failure, as it often led to sepsis and death, but Pott prevailed on them to splint the leg, and he ultimately recovered completely.
Percivall Pott's dedication to his patients and standard of care garnered Pott high praise and fame. He is generally regarded as one of the two greatest surgeons of the 18th century along with his student John Hunter.
Amid the patient wards, Pott also honed his writing skills and believed in patient education. He would distribute pamphlets, noting his observations and thoughts on topics ranging from "head injuries, hydrocele, fistula, rupture, and fracture", in the hospital environment. These pamphlets were in high demand and would sell for more than one shilling and sixpence. Between the 1760s and the 1770s over fourteen of Pott's pamphlets were in circulation.
In 1769 Pott published Some Few Remarks upon Fractures and Dislocations. The book was translated into French and Italian and had a far-reaching influence in Britain and France. His name was written in the annals of medicine, by first describing arthritic tuberculosis of the spine (Pott's disease). He gave an excellent clinical description in his Remarks on that Kind of Palsy of the Lower Limbs. Among his other writings, the most noteworthy are A Treatise on Ruptures (1756), and Chirurgical Observations.
In 1765, he was elected Master of the Company of Surgeons, the forerunner of the Royal College of Surgeons of England.
In 1775, Pott found an association between exposure to soot and a high incidence of scrotal cancer later found to be a type of squamous cell carcinoma in chimney sweeps. This disease, later termed chimney sweeps' carcinoma due to Pott's investigation, was the first occupational link to cancer, and Pott became the first person to associate a malignancy with an environmental carcinogen, implicating chimney soot as a direct contact carcinogen to skin.
A manuscript of his 1779 lectures on surgery is held in the medical manuscripts collection of the University of Manchester Library.
In 1786, he was honoured as the first Honorary Fellow of the Royal College of Surgeons of Edinburgh. Shortly after, he retired in 1787 and was named a governor of St. Bartholomew's Hospital.
in 1740, Percivall Pott married Sarah Elizabeth Cruttenden (1725–1811), daughter of the wealthy merchant Robert Cruttenden and his wife Sarah Cliff. They lived together in Lincoln's Inn Fields in London and had five sons and four daughters, including Joseph Pott, Archdeacon of London, Samuel, a leading newspaper editor and owner of Saunders Newsletter, and Mary (Polly), who married the long-serving Irish judge Robert Day.
Although little more is known about Percivall Pott's private life, Pott is regularly described as having excellent character, and an archetypical English surgeon. It is believed that Pott's standard of living (he was rich enough to give Polly a dowry of £5000) was a contributor to the rise of the surgeon within social standings.
Percivall Pott has influenced medicine and modern understanding of diseases. Many diseases are his namesake including: Pott's fracture, Pott's disease of the spine, and Pott's puffy tumor. One disease which does not, yet is important to Pott's legacy is chimney sweeper's carcinoma. Pott quickly recognised the association between carcinoma and chimney sweeps and published his findings in a piece titled "Chirurgical Observations relative to…the cancer of the scrotum." He wrote that the disease was, " peculiar to a certain sort of people [ and ] which has not at least to my knowledge, been publicly noticed – I mean the chimney-sweepers ’ cancer. The disease, in these people, seems to derive its origin from a lodgment of soot in the rugae of the scrotum."
Discovery and identification credit
Scrotal cancer, although largely thought to have been identified by Percivall Pott, had been thought to have been described nearly 40 years before Pott's "Chirurgical Observations" as a "canker of privities" per documentation in the burial records of the Parish of St. Botolph without Aldgate from 1589 to 1599. These descriptions are ambiguous and it is unclear which anatomical parts are considered "privities". As such, most historians generally agree, that Bassius first correctly described scrotal cancer in 1731. Some historians argue that what Bassius considered scrotal cancer was in fact perineal abscesses to the scrotum as opposed to carcinoma. The minority of historians who agree with this fact, attribute the discovery of scrotal cancer to Treyling in 1740.
As a surgeon, Pott was well respected and often assisted fellow surgeons. Pott was viewed as a mentor and even allowed other physicians and surgeons to live with him while under his guidance. Despite the surgical trends of his time, Pott did not agree with severe treatments and heroic medicine but rather preferred gentler forms. Percivall Pott's son-in-law, James Earle, described Pott's surgery as being "divested of great part of its horrors, became, comparatively, a pleasing study."
