Robert Boyle (
25 January 1627 –
30 December 1691) was an
Anglo-
Irish natural philosopher, chemist, physicist, inventor, and early
gentleman scientist, noted for his work in
physics and
chemistry. He is best known for the formulation of
Boyle's law. Although his research and personal philosophy clearly has its roots in the alchemical tradition, he is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry. He is very famous in the science world for being the first scientist that kept accurate experiment logs. Among his works,
The Sceptical Chymist is seen as a cornerstone book in the field of chemistry.
Early years Returning to England in
1645 he found that his father was hospitalized and had left him the manor of
Stalbridge in
Dorset, together with estates in
Ireland. From that time, he devoted his life to
scientific research, and soon took a prominent place in the band of inquirers, known as the "
Invisible College", who devoted themselves to the cultivation of the "new philosophy". They met frequently in London, often at
Gresham College; some of the members also had meetings at
Oxford, and in that city Boyle went to reside in 1654. Reading in 1657 of
Otto von Guericke's air-pump, he set himself with the assistance of
Robert Hooke to devise improvements in its construction, and with the result, the "machina Boyleana" or "Pneumatical Engine", finished in 1659, he began a series of experiments on the properties of air. An inscription can be found on the wall of
University College, Oxford in the
High Street at
Oxford (now the location of the
Shelley Memorial), marking the spot where Cross Hall stood until the early 1800s. It was here Boyle rented rooms from the wealthy apothecary who owned the Hall:
An account of the work he did with this instrument was published in 1660 under the title
New Experiments Physico-Mechanical. Among the critics of the views put forward in this book was a
Jesuit,
Franciscus Linus (1595–1675), and it was while answering his objections that Boyle made his first mention of the law that the volume of a gas varies inversely to the pressure of the gas, which among English-speaking peoples is usually called after his name. However, the person that originally formulated the hypothesis was Henry Power in 1661. Boyle included a reference to a paper written by Power, but mistakenly attributed it to Richard Townley. In continental Europe the hypothesis is sometimes attributed to
Edme Mariotte, although he did not publish it until 1676 and was likely aware of Boyle's work at the time. In 1663 the Invisible College became the
Royal Society of London for the Improvement of Natural Knowledge, and the charter of incorporation granted by
Charles II of England, named Boyle a member of the council. In 1680 he was elected president of the society, but declined the honour from a scruple about oaths.
It was during his time at Oxford that Boyle was a
Chevalier. The Chevaliers are thought to have been established by royal order a few years before Boyle's time at Oxford. The period of Boyle's residence was marked by the reactionary actions of the victorious parliamentarian forces, consequently this period marked the most secretive period of Chevalier movements and thus little is known about Boyle's involvement beyond his membership.
In 1668 he left Oxford for
London where he resided at the house of his sister, Lady Ranelagh, in
Pall Mall.
Middle years In 1689 his health, never very strong, began to fail seriously and he gradually withdrew from his public engagements, ceasing his communications to the Royal Society, and advertising his desire to be excused from receiving guests, "unless upon occasions very extraordinary", on Tuesday and Friday forenoon, and Wednesday and Saturday afternoon. In the leisure thus gained he wished to "recruit his spirits, range his papers", and prepare some important chemical investigations which he proposed to leave "as a kind of Hermetic legacy to the studious disciples of that art", but of which he did not make known the nature. His health became still worse in 1691, and his death occurred on
December 30 of that year, just a week after that of the sister with whom he had lived for more than twenty years. He was buried in the churchyard of
St Martin's in the Fields, his funeral sermon being preached by his friend Bishop Burnet. In his will, Boyle endowed a series of Lectures which came to be known as the
Boyle Lectures.
Later years Boyle's great merit as a scientific investigator is that he carried out the principles which
Francis Bacon preached in the
Novum Organum. Yet he would not avow himself a follower of Bacon, or indeed of any other teacher. On several occasions he mentions that in order to keep his judgment as unprepossessed as might be with any of the modern theories of philosophy, until he was "provided of experiments" to help him judge of them, he refrained from any study of the
Atomical and the
Cartesian systems, and even of the Novum Organum itself, though he admits to "transiently consulting" them about a few particulars. Nothing was more alien to his mental temperament than the spinning of hypotheses. He regarded the acquisition of knowledge as an end in itself, and in consequence he gained a wider outlook on the aims of scientific inquiry than had been enjoyed by his predecessors for many centuries. This, however, did not mean that he paid no attention to the practical application of science nor that he despised knowledge which tended to use.
He himself was an
alchemist; and believing the
transmutation of metals to be a possibility, he carried out experiments in the hope of effecting it; and he was instrumental in obtaining the repeal, in 1689, of the statute of
Henry IV against
multiplying gold and
silver. With all the important work he accomplished in
physics - the enunciation of
Boyle's law, the discovery of the part taken by air in the propagation of
sound, and investigations on the expansive force of freezing water, on
specific gravities and
refractive powers, on
crystals, on
electricity, on
colour, on
hydrostatics, etc.-
chemistry was his peculiar and favourite study. His first book on the subject was
The Sceptical Chymist, published in 1661, in which he criticized the "experiments whereby vulgar
Spagyrists are wont to endeavour to evince their
Salt,
Sulphur and
Mercury to be the true Principles of Things.". For him chemistry was the science of the composition of substances, not merely an adjunct to the arts of the alchemist or the physician. He advanced towards the modern view of elements as the undecomposable constituents of material bodies; and understanding the distinction between
mixtures and
compounds, he made considerable progress in the technique of detecting their ingredients, a process which he designated by the term "analysis". He further supposed that the elements were ultimately composed of
particles of various sorts and sizes, into which, however, they were not to be resolved in any known way. Applied chemistry had to thank him for improved methods and for an extended knowledge of individual substances. He also studied the chemistry of
combustion and of
respiration, and conducted experiments in
physiology, where, however, he was hampered by the "tenderness of his nature" which kept him from anatomical
dissections, especially of living animals, though he knew them to be "most instructing".
Besides being a busy natural philosopher, Boyle devoted much time to
theology, showing a very decided leaning to the practical side and an indifference to controversial
polemics. At the
Restoration he was favourably received at court, and in 1665 would have received the provostship of
Eton, if he would have taken orders; but this he refused to do on the ground that his writings on religious subjects would have greater weight coming from a layman than a paid minister of the Church. As a director of the
East India Company he spent large sums in promoting the spread of
Christianity in the East, contributing liberally to
missionary societies, and to the expenses of translating the
Bible or portions of it into various languages. He founded the
Boyle lectures, intended to defend the
Christian religion against those he considered "notorious infidels, namely
atheists,
deists,
pagans,
Jews and
Muslims", with the provison that controversies between Christians were not to be mentioned. In 2004, the Boyle Lectures were resurrected in London . In person Boyle was tall, slender and of a pale countenance. His constitution was far from robust, and throughout his life he suffered from feeble health and low spirits. While his scientific work procured him an extraordinary reputation among his contemporaries, his private character and virtues, the charm of his social manners, his wit and powers of conversation, endeared him to a large circle of personal friends. He was never married. His writings are exceedingly voluminous, and his style is clear and straightforward, though undeniably verbose.
In 2004
The Robert Boyle Science Room was opened in the
Lismore Heritage Centre, near his birthplace, dedicated to his life and works where students have the opportunity of studying science and participating in scientific experiments.
