Robert Boyle (1627-1691)

Boyle, a chemist and physicist, was born in Lismore Castle, Munster, Ireland, in January 25th 1627, and died, in London, in December 30th 1691. Boyle is sometimes considered the "father of modern Chemistry".

In the winter of 1641, he went to Florence where carefully studied the works of Galileu, leading him to a mecanicist philosophy. He was one of the first researchers to have a scientific approach to the atomism of the Ancient Greeks, as an opposition to the four element theory of Aristotle and the Paracelsus theories. His book The Sceptical Chemist opened a new era in the history of Chemistry, where terms like atom or molecule appeared.

Boyle is often considered the founder of chemical analysis due to his studies of materials composition. His skeptical attitude was not enough to avoid some passionate work in alchemy.

Boyle also made important work in hydrostatics, sound and breathing phenomena, being responsible, along with Hooke, for the construction of the pneumatic machine performing various gas pressure experiences. He also verified the inverse relationship between pressure and volume at constant temperature (Law of Boyle-Mariotte).
