Robert Boyle
Robert Boyle (Lismore Castle, Waterford County, Ireland, January 25, 1627 – London, December 30, 1691) was a British chemist and physicist, mainly known for Boyle's law (1662) that states that the pressure of a fixed amount of gas is inversely proportional to its volume. The experimental work that lead to this law was by means of an air pump invented in 1634 by Otto von Guericke, the Burgomaster of Magdeburg. The pump was greatly improved by Boyle in corporation with his assistant Robert Hooke.
Boyle was the first to state that a chemical compound consists of small particles, which he called "corpuscles". He was one of the first to prepare phosphorus (see phosphorus for more details about the discovery of the element) and the first to describe hydrogen gas. Although he was one of the first chemists in the modern sense of the word, he still believed, as the alchemists did, that transmutation of individual chemical elements was possible.
Boyle's main contributions to chemistry are the following: (1) he realized that chemistry is worthy of study for its own sake, and not merely an aid to alchemy (although he did not reject the latter); (2) he introduced rigorous experimental methods into chemistry; (3) he gave a clear definition of a chemical element and showed by experiment that the four elements of Aristotle and the three principles of the alchemists (mercury, sulfur, and salt) did not deserve to be called elements or principles at all, since none of them could be extracted from bodies, e.g., from metals.
Boyle was one of the founders of the Royal Society of London, chartered in 1662.
Biography
Robert Boyle was born as his parents' fourteenth child and seventh son, the last to survive to adulthood. His mother died in childbirth a few weeks after Robert's third birthday.
Robert's father, Richard Boyle, is remembered as the "Great Earl of Cork". Richard Boyle, who was not from rich background, had gone to Ireland in 1588 to seek his fortune. This was the time that England was colonizing all of Ireland, resulting in the complete conquest of Ireland by 1603. In a few years, due partly to good marriages—first (1595) to a rich widow and second (1603) to the 17-year old Catherine Fenton, Robert's mother and daughter of the Secretary of State for Ireland—and due to the influential friends in Court, Robert's father had risen to "Sir Richard Boyle, Knight, Lord Boyle, Baron of Youghall, Lord Dungarvan, Earl of Cork, Lord High Treasurer of Ireland". At the time of Robert's birth his father's means amounted to two hundred and fifty pounds a day exclusive of houses and parks and it was said that he was the richest man of England.
Robert Boyle was a competent linguist from an early age, and was reputed to be fluent in French and Latin at the age of eight. As a young boy of nine he went to Eton, together with his brother Francis. After three years at Eton, the Boyle brothers engaged a French tutor and traveled for five years on the European continent, visiting France, Switzerland, and Italy.
When visiting Geneva during his grand tour, the fourteen year old Boyle underwent what he clearly felt to be a conversion from nominal, or at least unthinking, Christianity to committed Christianity and he promised himself then that he would live a pious Christian life. In adult life he wrote Christian devotional and ethical essays and theological tracts on biblical language, the limits of reason, and the role of the natural philosopher as a Christian. He sponsored many religious missions, as well as the translation of the Scriptures into several languages. Throughout his life, he spread large parts of his income widely in charitable donations and he left most of his property to charity after his death.
During their tour of Europe, the brothers were in Florence when Galileo Galilei died. The huge public attention that this event drew roused Robert's curiosity and he began reading widely about Galileo and his work; this seems to have been a key event in developing the young man's interest in science. A few months later, when the boys were back in Geneva, Francis was called home because of the Irish rebellion that started November 1641 and that put great strain on the finances of the "Great Earl of Cork". Much of Boyle senior's possessions were in Ireland and he had to pay large mercenary forces to keep the Irish rebels in hand. Earlier he had paid his sons a thousand pounds a year and now had difficulty to pay 250 pounds for the return of Francis (money that did not reach Francis but was embezzled on the way) to England. Robert stayed behind with his tutor in Geneva, had make ends meet, and pursued further studies.
He and his tutor returned to England in 1644, after his father the "Great Earl" had died. He took up residence at his hereditary estate of Stalbridge in Dorset. Here he began a literary career writing ethical and devotional tracts, some of which employed stylistic and rhetorical models drawn from French popular literature, especially romance writings.
