The Sceptical Chymist is a cornerstone book in the history of chemistry.
It was written by Robert Boyle FRS (1627–1691). He was a 17th century natural philosopher, chemist, physicist, and inventor.
Boyle was an alchemist, but also the first modern chemist. He is famous for Boyle's law, which is about the relationship between the temperature and pressure of a gas.
