William Salmon, English medical writer (d. 1713)
William Salmon (1644–1713) was an English empiric doctor and a writer of medical texts. He advertised himself as a "Professor of Physick". Salmon held an equivocal place in the medical community. He led apothecaries in opposing attempts by physicians to control the dispensing of medicines, and was derided by physicians as "the King of the Quacks".: 118  He has been described as "a brilliant publicist, but not much of a philosopher".Salmon "copied, translated, abridged, enlarged and compiled from the texts of others" to create popular books emphasizing practice over theory, and often marketing his own medications. A prolific author on a broad range of medical topics, Salmon's works were widely read in his time. His books were owned by respected men including Isaac Newton, Daniel Defoe, William Congreve and Samuel Johnson.
