William Buchan (1729 – 25 February 1805) was a Scottish physician and author. He is best known for his work Domestic Medicine: or, a Treatise on the Prevention and Cure of Diseases by Regimen and Simple Medicines, which provided laypeople with detailed descriptions of the causes and prevention of diseases. Buchan’s goal was one of "laying medicine more open to mankind." With over 80,000 copies and 19 editions sold in Buchan’s lifetime, it was one of the most popular medical texts in Europe, and was translated into almost every major European language.
