Robert Boyle


Here is a short biography of the owner of Stalbridge House in the 17th century.  


Robert Boyle FRS was born on 25th January 1627 and died on 31st December 1691. He  was an Anglo-Irish natural philosopherchemistphysicist and inventor.
Boyle is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry and one of the pioneers of modern experimental scientific method.
He is best known for Boyle's law, describing the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system. Among his works, The Sceptical Chymist, is seen as a cornerstone book in the field of chemistry. He was a devout and pious Anglican and is noted for his writings in theology.

Boyle was born at Lismore Castle, in County Waterford, Ireland, the seventh son and fourteenth child of The 1st Earl of Cork ('the Great Earl of Cork') and Catherine Fenton. Lord Cork, then known simply as Richard Boyle, had arrived in Dublin from England in 1588 during the Tudor plantations of Ireland and obtained an appointment as a deputy escheator. He had amassed enormous wealth and landholdings by the time Robert was born and had been created Earl of Cork in October 1620. Catherine Fenton, Countess of Cork, was the daughter of Sir Geoffrey Fenton, the former Secretary of State for Ireland, who was born in Dublin in 1539 and Alice Weston, the daughter of Robert Weston, who was born in Lismore in 1541.
As a child, Boyle was fostered to a local family, as were his elder brothers. Boyle received private tutoring in Latin, Greek, and French and when he was eight years old, following the death of his mother, he was sent to Eton College in England. His father's friend, Sir Henry Wotton, was then the provost of the college. After spending over three years at Eton, Robert travelled abroad with a French tutor. They visited Italy in 1641 and remained in Florence during the winter of that year studying the "paradoxes of the great star-gazer" Galileo Galilei, who was elderly but still living in 1641.

Robert returned to England from continental Europe in mid-1644 with a keen interest in scientific research. His father, Lord Cork, had died the previous year and had left him the manor of Stalbridge in Dorset as well as substantial estates in County Limerick in Ireland. Robert then made his residence at Stalbridge House, between 1644 and 1652, and conducted many experiments there. From that time, Robert devoted his life to scientific research and soon took a prominent place in the band of enquirers, known as the "Invisible College", who devoted themselves to the cultivation of the "new philosophy". They met frequently in London, often at Gresham College, and some of the members also had meetings at Oxford.
Having made several visits to his Irish estates beginning in 1647, Robert moved to Ireland in 1652 but became frustrated at his inability to make progress in his chemical work. In 1654, Boyle left Ireland for Oxford to pursue his work more successfully. An inscription can be found on the wall of University College, Oxford, the High Street at Oxford (now the location of the Shelley Memorial), marking the spot where Cross Hall stood until the early 19th century. It was here that Boyle rented rooms from the wealthy apothecary who owned the Hall.
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 account of Boyle's work with the air pump was published in 1660 under the title New Experiments Physico-Mechanical, Touching the Spring of the Air, and its Effects.
Among the critics of the views put forward in this book was a JesuitFrancis Line (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 people is usually called Boyle's Law after his name. The person who originally formulated the hypothesis was Henry Power in 1661. Boyle in 1662 included a reference to a paper written by Power, but mistakenly attributed it to Richard Towneley. 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 Improving 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.
He made a "wish list" of 24 possible inventions which included:
Ø  "the prolongation of life"
Ø  the "art of flying"
Ø  "perpetual light"
Ø  "making armour light and extremely hard"
Ø  "a ship to sail with all winds, and a ship not to be sunk"
Ø  "practicable and certain way of finding longitudes"
Ø  "potent drugs to alter or exalt imagination, waking, memory and other functions and appease pain, procure innocent sleep, harmless dreams, etc."
They are extraordinary because all but a few of the 24 have come true.
In 1668 he left Oxford for London where he resided at the house of his elder sister Katherine Jones, Lady Ranelagh, in Pall Mall. He experimented in the laboratory she had in her home and attended her salon of intellectuals interested in the sciences. The siblings maintained "a lifelong intellectual partnership, where brother and sister shared medical remedies, promoted each other’s scientific ideas, and edited each other’s manuscripts." His contemporaries widely acknowledged Katherine's influence on his work, but later historiographers dropped discussion of her accomplishments and relationship to her brother from their histories.
In 1669 his health, never very strong, began to fail seriously and he gradually withdrew from his public engagements, ceasing his communications to the Royal Society. 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 he died on 31 December that year, just a week after the death of his sister, Katherine, in whose home he had lived and with whom he had shared scientific pursuits for more than twenty years. Boyle died from paralysis. He was buried in the churchyard of St Martin-in-the-Fields, his funeral sermon being preached by his friend, Bishop Gilbert Burnet. In his will, Boyle endowed a series of lectures that came to be known as the Boyle Lecture.

'A Digger's Life: a load of rubbish'


The monthly meeting of the group saw Chris Tripp talk about how he got into archaeology and some of the sites he has dug over the last 30 years. From Bronze Age trackways, Roman warehouses and Iron Age settlements to Anglo-Saxon graves and Medieval cess pits. David Northam also talked through the possible project at Tumbledown Farm.
