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.
