Robert Boyle (1627–1691), an Irish-born English scientist, was an early supporter of the scientific method and founder of modern chemistry. Boyle is known for his pioneering experiments on the physical properties of gases, his authorship of the Sceptical Chymist, his role in creating the Royal Society of London, and his philanthropy in the American colonies.
