Pott’s observation extended the work of the Paduan physician Bernardino Ramazzini. In 1713, Ramazzini had published604 a monumental work—De Morbis Artificum Diatriba—that had documented dozens of diseases that clustered around particular occupations. Ramazzini called these diseases morbis artificum—man-made diseases. Soot cancer, Pott claimed, was one such morbis artificum—only in this case, a man-made disease for which the inciting agent could be identified. Although Pott lacked the vocabulary to describe it as such, he had discovered a carcinogen.
