Born into an Ulster Scots family, Thomson is the fourth son of Agnes Nesbit and James Thomson, a small farmer, at Annaghmore, near Ballynahinch, County Down, in Ulster. His early education is from his father. At the age of 11 or 12 he finds out for himself the art of dialling. His father sends him to a school at Ballykine, near Ballynahinch, kept by Samuel Edgar, father of John Edgar. Here he soon rises to be an assistant.
Wishing to become a minister of the Presbyterian church, Thomson enters the University of Glasgow in 1810, where he studies for several sessions, supporting himself by teaching in the Ballykine school during the summer. He graduates MA in 1812, and in 1814 he is appointed headmaster of the school of arithmetic, bookkeeping, and geography in the newly established Royal Belfast Academical Institution. In 1815 he is Professor of Mathematics in its collegiate department. Here he proves himself as a teacher. In 1829 the honorary degree of LL.D. is conferred upon him by the University of Glasgow, where in 1832 he is appointed Professor of Mathematics. He holds this post until his death on January 12, 1849.
Thomson is buried with his family on the northern slopes of the Glasgow Necropolis to the east of the main bridge entrance. The grave is notable due to the modern memorial to Lord Kelvin at its side.
Thomson is the author of schoolbooks that have passed through many editions including Arithmetic (1819), Trigonometry, Plane and Spherical (1820), Introduction to Modern Geography (1827), The Phenomena of the Heavens (1827), The Differential and Integral Calculus (1831), and Euclid (1834).
A paper, “Recollections of the Battle of Ballynahinch, by an Eye-witness,” which appears in the Belfast Magazine for February 1825, is from his pen.
Andrews begins a successful medical practice in his native Belfast in 1835, also giving instruction in chemistry at the Academical Institution. In 1842, he marries Jane Hardie Walker (1818–1899). They have six children, including the geologistMary Andrews. In 1845 he is appointed vice-president of the newly established Queen’s University Belfast, and professor of chemistry there. He holds these two offices until his retirement in 1879 at age 66.
Andrews first becomes known as a scientific investigator with his work on the heat developed in chemical actions, for which the Royal Society awards him a Royal Medal in 1844. Another important investigation, undertaken in collaboration with Peter Guthrie Tait, is devoted to ozone.
Andrews’ reputation mainly rests on his work with liquefaction of gases. In the 1860s he carries out a very complete inquiry into the gas laws, expressing the relations of pressure, temperature, and volume in carbon dioxide. In particular, he establishes the concepts of critical temperature and critical pressure, showing that a substance passes from vapor to liquid state without any breach of continuity.
In Andrews’ experiments on phase transitions, he shows that carbon dioxide may be carried from any of the states we usually call liquid to any of those we usually call gas, without losing homogeneity. The mathematical physicist Josiah Willard Gibbs cites these results in support of the Gibbs free energy equation. They also set off a race among researchers to liquify various other gases. In 1877-78 Louis Paul Cailletet is the first to liquefy oxygen.
Andrews dies in Belfast on November 26, 1885, and is buried in the Borough Cemetery in the city.
Sir Joseph LarmorFRSFRSE, Irish and British physicist and mathematician who makes breakthroughs in the understanding of electricity, dynamics, thermodynamics, and the electron theory of matter, is born in Magheragall, County Antrim on July 11, 1857. His most influential work is Aether and Matter, a theoretical physics book published in 1900.
In 1903 Larmor is appointed Lucasian Professor of Mathematics at Cambridge, a post he retains until his retirement in 1932. He never marries. He is knighted by King Edward VII in 1909.
Drennan is born on May 23, 1754 in Belfast, the son the son of ReverendThomas Drennan (1696–1768), minister of Belfast’s First Presbyterian Church on Rosemary Street. Thomas Drennan is an educated man from the University of Glasgow and is ordained to the congregation of Holywood, County Down in 1731. Drennan is heavily influenced by his father, whose religious convictions serve as the foundation for his own radical political ideas. His sister, Martha, marries fellow future United Irishman Samuel McTier in 1773.
In 1769 Drennan follows in his father’s footsteps by enrolling in the University of Glasgow where he becomes interested in the study of philosophy. In 1772 he graduates in arts and then in 1773 he commences the study of medicine at Edinburgh. After graduating in 1778 he sets up practice in Belfast, specialising in obstetrics. He is credited with being one of the earliest advocates of inoculation against smallpox and of hand washing to prevent the spread of infection. He also writes much poetry, coining the phrase “Emerald Isle” and is the founder and editor of a literary periodical, Belfast Magazine. He moves to Newry in 1783 but eventually moves to Dublin in 1789 where he quickly becomes involved in nationalist circles.
Like many other UlsterPresbyterians, Drennan is an early supporter of the American Colonies in the American Revolution and joins the Volunteers who had been formed to defend Ireland for Britain in the event of French invasion. The Volunteer movement soon becomes a powerful political force and a forum for Protestant nationalists to press for political reform in Ireland eventually assisting Henry Grattan to achieve legislative independence for the Irish parliament in 1782. However Drennan, like many other reformers, quickly becomes dismayed by the conservative and sectarian nature of the Irish parliament and in 1791 he co-founds the Society of United Irishmen with Wolfe Tone and Thomas Russell.
Drennan writes many political pamphlets for the United Irishmen and is arrested in 1794 for seditious libel, a political charge that is a major factor in driving the United Irishmen underground and into becoming a radical revolutionary party. Although he is eventually acquitted, he gradually withdraws from the United Irishmen but continues to campaign for Catholic Emancipation.
On February 8, 1800, Drennan marries Sarah Swanwick, “an English lady of some wealth” from Shropshire. They have one daughter and four sons.
Drennan settles in Belfast in 1807. In 1810 he co-founds the non-denominational Royal Belfast Academical Institution. As a poet, he is best remembered for his poem The Wake of William Orr, written in memory of a United Irishman executed by the British. Despite his links with revolutionary republicans, he gradually becomes alienated from the post-Union nationalism of the period. His abiding concern for Liberalism and post union realities make him contemplate his political ideas anew.
Drennan dies in Belfast on February 5, 1820. He directs that his coffin be carried by an equal number of Catholics and Protestants with clergy from different denominations in attendance.
Francis Hutcheson, Scotch-Irishphilosopher and major exponent of the theory of the existence of a moral sense through which man can achieve right action, is born on August 8, 1694 in Saintfield, County Down, Ulster. He is remembered for his book A System of Moral Philosophy. He is an important influence on the works of several significant Enlightenment thinkers, including David Hume and Adam Smith.
Hutcheson is licensed as a preacher in 1719 by Irish Presbyterians in Ulster, but in 1738 the Glasgow presbytery challenges his belief that people can have a knowledge of good and evil without, and prior to, a knowledge of God. His standing as a popular preacher is undiminished, however, and the celebrated Scottish philosopher David Hume seeks his opinion of the rough draft of the section “Of Human Morals” in Hume’s A Treatise of Human Nature.
Hutcheson’s ethical theory is propounded in his Inquiry into the Original of Our Ideas of Beauty and Virtue (1725), in Essay on the Nature and Conduct of the Passions and Affections (1728) and Illustrations upon the Moral Sense (1728), and in the posthumous A System of Moral Philosophy (1755). In his view, besides his five external senses, man has a variety of internal senses, including a sense of beauty, of morality, of honour, and of the ridiculous. Of these, Hutcheson considers the moral sense to be the most important. He believes that it is implanted in man and pronounces instinctively and immediately on the character of actions and affections, approving those that are virtuous and disapproving those that are vicious. His moral criterion is whether or not an act tends to promote the general welfare of mankind. He thus anticipates the utilitarianism of the English thinker Jeremy Bentham, even to his use of the phrase “the greatest happiness for the greatest number.” Hutcheson is also influential as a logician and theorist of human knowledge.
Hutcheson spends time in Dublin, and dies while on a visit to the city on August 8, 1746, his fifty-second birthday. He is buried in the churchyard of Saint Mary’s, which is also the final resting place of his cousin William Bruce. Today Saint Mary’s is a public park located in what is now Wolfe Tone Street. He lies in what is now an unmarked grave in the Dublin he loved and where his best work was done.
Charles is the eldest son of James Francis Edward Stuart, the exiled Stuart claimant to the British throne. Believing there is support for a Stuart restoration in both Scotland and England, he lands in Scotland in July 1745. The Jacobite Army is often assumed to have been largely composed of Gaelic-speaking Catholic Highlanders. In reality nearly a quarter of the rank and file are recruited in Aberdeenshire, Forfarshire and Banffshire, with another 20% from Perthshire. Although the army is predominantly Scots it contains a few English recruits plus significant numbers of Irish, Scottish and French professionals in French service with the Irish Brigade and Garde Écossaise.
After amassing his army of Scots Jacobite supporters, Charles takes Edinburgh by September and defeats a British government force at Prestonpans. The government recalls 12,000 troops from the Continent to deal with the rising. A Jacobite invasion of England reaches as far as Derby before turning back, having attracted relatively few English recruits.
The Jacobites, with limited French military support, attempt to consolidate their control of Scotland, where by early 1746 they are opposed by a substantial government army. A scrambled Jacobite victory at Falkirk fails to change the strategic situation. With supplies and pay running short and with the government troops resupplied and reorganised under the Duke of Cumberland, son of British monarch George II, the Jacobite leadership has few options left other than to stand and fight. The two armies eventually meet at Culloden, on terrain that gives Cumberland’s larger, well-rested force the advantage.
The battle lasts only an hour, with the Jacobites suffering a bloody defeat with between 1,500 and 2,000 killed or wounded. Approximately 300 government soldiers are killed or wounded. While perhaps as many as 6,000 Jacobites remain in arms in Scotland, the leadership takes the decision to disperse, effectively ending the rising. The men of the combined Irish regiments, under the command of Brigadier Walter Stapleton, are the last off the field, covering the retreat of Prince Charles and the remnants of his army. The Irish had given their blood to the cause of a Stuart King for the last time. Most of the surviving Irish surrender at Inverness. The Prince himself eventually manages to make his escape to France.
Culloden and its aftermath continue to arouse strong feelings. The University of Glasgow awards the Duke of Cumberland an honorary doctorate, but many modern commentators allege that the aftermath of the battle and subsequent crackdown on Jacobite sympathisers were brutal, earning Cumberland the sobriquet “Butcher.” Efforts are subsequently made to further integrate the comparatively undeveloped Scottish Highlands into the Kingdom of Great Britain. Civil penalties are introduced to undermine the Scottish clan system, which had provided the Jacobites with the means to rapidly mobilise an army.
Today, a visitor centre is located near the site of the battle. This centre is first opened in December 2007, with the intention of preserving the battlefield in a condition similar to how it was on April 16, 1746. One difference is that it currently is covered in shrubs and heather. During the 18th century, however, the area was used as common grazing ground, mainly for tenants of the Culloden estate. Those visiting can walk the site by way of footpaths on the ground and can also enjoy a view from above on a raised platform. Possibly the most recognisable feature of the battlefield today is the 20-foot tall memorial cairn, erected by Duncan Forbes in 1881. In the same year Forbes also erects headstones to mark the mass graves of the clans.
Thomson spends much of his youth in Glasgow. His father James is professor of mathematics at the University of Glasgow from 1832 onward. He attends Glasgow University from a young age and graduates in 1839 with high honors in his late teens. After graduation, he serves brief apprenticeships with practical engineers in several domains. He then gives a considerable amount of his time to theoretical and mathematical engineering studies, often in collaboration with his brother, during his twenties in Glasgow. In his late twenties he enters into private practice as a professional engineer with special expertise in water transport. In 1855, he is appointed professor of civil engineering at Queen’s University Belfast. He remains there until 1873, when he accepts the Regius professorship of Civil Engineering and Mechanics at the University of Glasgow in which he is successor to the influential William Rankine. He serves in this position until he resigns with failing eyesight in 1889.
Thomson dies of cholera in Glasgow on May 8, 1892. He is buried on the northern slopes of the Glasgow Necropolis overlooking Glasgow Cathedral. One obituary describes Thomson as “a man of singular purity of mind and simplicity of character,” whose “gentle kindness and unfailing courtesy will be long remembered.”
Thomson is known for his work on the improvement of water wheels, water pumps and turbines. He is also known for his innovations in the analysis of regelation, i.e., the effect of pressure on the freezing point of water, and his studies in glaciology including glacial motion, where he extends the work of James David Forbes. He studies the experimental work of his colleague Thomas Andrews concerning the continuity of the liquid and gaseous states of matter, and strengthens understanding of it by applying his strong knowledge of thermodynamics. He derives a simplified form of the Clapeyron equation for the solid-liquid phase boundary. He proposes the term triple point to describe the conditions for which solid, liquid and vapour states are all in equilibrium.
Thomson also makes contributions in the realm of fluid dynamics of rivers. It is claimed that the term torque is introduced into English scientific literature by Thomson in 1884.
Abernethy’s father, also named John, a Presbyterian minister, accompanies Patrick Adair on a deputation from the general committee of Ulster presbyterians, who present a congratulatory address to William III in London in 1689, and obtain from the king a letter (November 9, 1689) recommending their case to Meinhardt Schomberg, 3rd Duke of Schomberg.
At the age of 13, Abernethy enters the University of Glasgow and, upon concluding his course there, goes on to the University of Edinburgh, where he soon moves in the most cultured circles. Returning home, he is licensed to preach from his Presbytery before he is twenty-one. In 1701 he is called to accept charge of an important congregation in Antrim. After an interval of two years, mostly spent in further study in Dublin, he is ordained there on August 8, 1703. He becomes a noted debater in the synods and assemblies of his church and a leading evangelist. He has been described as being at this time “the young minister of Antrim … a man of studious habits, heretical opinions, and remarkable ability.”
In 1712, he is devastated by the loss of his wife, Susannah Jordan. Five years later, he is invited to the congregation of Usher’s Quay, Dublin, and also to what is called the Old Congregation of Belfast. The synod assigns him to Dublin. After careful consideration he refuses and remains at Antrim. This refusal arouses disapproval and a controversy follows, with Abernethy standing firm for religious freedom and repudiating the ecclesiastical courts. The controversy and quarrel bears the name of the two camps in the conflict, the “Subscribers” and the “Non-subscribers.” Abernethy and his associates sow the seeds of the struggle (1821–1840) in which, under the leadership of Dr. Henry Cooke, the Arian and Socinian elements of the Presbyterian Church in Ireland are thrown out.
Much of what Abernethy contends for, and which the “Subscribers” oppose bitterly, is silently granted in the lapse of time. In 1726, the “Non-subscribers” are cut off, with due ban and solemnity, from the Presbyterian Church of Ireland. In 1730 he moves to Wood Street, Dublin. It is said of him that, although a “Non-subscriber,” he is a Trinitarian. However, Dr. Cooke states that Arianism “made very considerable progress under the patronage of high names, as Abernethy, the author of a very excellent work upon the Attributes, who gave it a great deal of eclat.”
In 1731 comes the greatest controversy in which Abernethy is involved. It is nominally about the Test Act, but actually on the entire question of tests and disabilities. His stand is against all laws that, upon account of mere differences of religious opinions and forms of worship, exclude men of integrity and ability from serving their country.
Abernethy is nearly a century in advance of his age. He has to reason with those who deny that a Roman Catholic or Dissenter can be a “man of integrity and ability.”

Very little is known of Toland’s early life. His parents are unknown. He later writes that he had been baptised Janus Junius, a play on his name that recalls both the Roman two-faced god Janus and Lucius Junius Brutus, reputed founder of the Roman Republic. According to his biographer, Pierre des Maizeaux, he adopts the name John as a schoolboy with the encouragement of his school teacher.
In Toland’s first and best known book, Christianity not Mysterious (1696), he argues that the divine revelation of the Bible contains no true mysteries. Rather, all the dogmas of the faith can be understood and demonstrated by properly trained reason from natural principles. For this argument he is prosecuted by a grand jury in London. As he is a subject of the Kingdom of Ireland, members of the Parliament of Ireland propose that he should be burned at the stake. In his absence three copies of the book are burned by the public hangman in Dublin as the content is contrary to the core doctrines of the Church of Ireland. Toland bitterly compares the Protestant legislators to “Popish Inquisitors who performed that Execution on the Book, when they could not seize the Author, whom they had destined to the Flames.”
After his departure from Oxford, Toland resides in London for most of the rest of his life, but is also a somewhat frequent visitor to Continental Europe, particularly Germany and the Netherlands. He lives on the Continent from 1707 to 1710.
John Toland dies in Putney on March 10, 1722. Just before he dies, he composes his own epitaph: “He was an assertor of liberty, a lover of all sorts of learning … but no man’s follower or dependent. Nor could frowns or fortune bend him to decline from the ways he had chosen.” The 1911 Encyclopædia Britannica says of him that at his death in London at age 51 “he died… as he had lived, in great poverty, in the midst of his books, with his pen in his hand.”
Very shortly after his death a lengthy biography of Toland is written by Pierre des Maizeaux.
