Smith is the fourth child of John Smith (1792–1828), a barrister, who dies when Henry is two. His mother, Mary Murphy (d.1857) from Bantry Bay, very soon afterward moves the family to England. He has thirteen siblings, including Eleanor Smith, who becomes a prominent educational activist. He lives in several places in England as a boy. His mother does not send him to school but educates him herself until age 11, at which point she hires private tutors. In 1841, at the age of 15, he is admitted to Rugby School in Warwickshire, where Thomas Arnold is the school’s headmaster. This comes about because his tutor, Henry Highton, takes up a housemaster position there.
At the age of 19 Smith wins an entrance scholarship to Balliol College, Oxford. He graduates in 1849 with high honours in both mathematics and classics. He is fluent in French having spent holidays in France, and he takes classes in mathematics at the College of Sorbonne in Paris during the 1846–47 academic year. He is unmarried and lives with his mother until her death in 1857. He then brings his sister, Eleanor, to live with him as housekeeper at St. Giles.
Smith remains at Balliol College as a mathematics tutor following his graduation in 1849 and is soon promoted to Fellow status.
In 1874, Smith becomes Keeper of the University Museum and moves, along with his sister, to the Keeper’s House on South Parks Road in Oxford.
On account of his ability as a man of affairs, Smith is in demand for academic administrative and committee work: he is Keeper of the Oxford University Museum of Natural History, a Mathematical Examiner for the University of London, a member of a Royal Commission to review scientific education practice, a member of the commission to reform University of Oxford governance, chairman of the committee of scientists overseeing the Meteorological Office and twice president of the London Mathematical Society.
Edgeworth Lysaght, later Edward Anthony Edgeworth Lysaght, and from 1920 Edward MacLysaght (Irish: Éamonn Mac Giolla Iasachta), a genealogist of twentieth century Ireland, is born on November 6, 1887, at Flax Bourton, Somerset, England. His numerous books on Irish surnames build upon the work of Rev. Patrick Woulfe’s Irish Names and Surnames (1923).
Lysaght is born to Sidney Royse Lysaght (1856-1941), of Irish origin, a director of the family iron and steel firm John Lysaght and Co. and a writer of novels and poetry, and Katherine (died 1953), daughter of Joseph Clarke, of Waddington, Lincolnshire. His grandfather, Thomas Royse Lysaght, is an architect, and his great-grandfather, William Lysaght, a small landowner distantly connected with the Barons Lisle. He is named “Edgeworth Lysaght” after his father’s friend, the economist Francis Ysidro Edgeworth. He loses the sight in one eye after a childhood accident.
Lysaght is educated at Nash House preparatory school, Bristol, and Rugby School at Rugby, Warwickshire, where he is unhappy, his parents’ frequent absence due to his father’s business responsibilities necessitating travel to South America, South Africa, and Australia contributing to this. He is a contemporary there of Rupert Brooke, whose father is Lysaght’s housemaster. Eighteen months after leaving Rugby, on the advice of Francis Edgeworth, he goes to Corpus Christi College, Oxford, to study law, but, having on his own account “had a wild time as part of the smart set” and anticipating rustication after a drunken incident, he leaves after three terms.
Lysaght takes up residence in a caravan at Lahinch, County Clare, where he had previously holidayed and become friendly with local people. His father, himself strongly connected to his Irish boyhood and wanting to establish himself as a “country gentleman,” recognizes his son’s enthusiasm for Ireland and in 1909 purchases a 600-acre estate at Tuamgraney, at which Lysaght farms until 1913, introducing an electrical generator and other forms of modernization including the development of a lime kiln, nursery, and school where young men of means can learn the basics of farming. This is the beginning of a metamorphosis for him. Although of English upbringing, he dislikes the local gentry, considering them “layabout rentiers,” and prefers to make friendships amongst employees and his neighbours. He seeks to replace his English accent with a Clare accent, eschews his lack of religion of a few years before in favour of Roman Catholicism, and becomes involved in the Gaelic League.
An integral factor in Lysaght’s reinvention is his relationship with Mabel (“Maureen”) Pattison. Five years his senior, they meet when he spends a period at a Dublin hospital. She is born and raised in South Africa, her father a civil servant there, but has Irish family including a local postmistress. His family seeks to avoid what they consider an unsuitable marriage, sending him and his brother Patrick on a world tour, but the couple are nevertheless married at the Brompton Oratory on September 4, 1913. Mabel introduces him to friends in the Arts Club, and he enters Dublin literary society. His father invests £300 in Maunsell’s publishers, who produces Lysaght’s book of poems, Irish Eclogues. As of the early 1930s, he serves on the General Committee of the Munster Agricultural Society.
By 1915, Lysaght’s command of the Irish language has improved dramatically, and in that year he founds the Nua-Ghaeltacht at Raheen, County Clare. He is an independent delegate to the 1917-18 Irish Convention in which he opposes John Redmond‘s compromise on Home Rule. By 1918 his involvement in all aspects of the Irish independence movement have deepened greatly. Although not known if he is actually a member of the Irish Republican Army (IRA), he is very active in the Irish War of Independence as a supporter, financially and otherwise, of the East Clare Brigade of the IRA and its legendary leaders, Michael and Conn Brennan.
In 1920, Lysaght, along with others of the name, changes his name to “MacLysaght,” “so as to emphasise its Gaelic origin.”
MacLysaght’s Raheen office serves as a meeting place for the Volunteers and guns, documents and ammunition are stored there. However, the war leads to a sharp decline in the fortunes of his farm. The execution of close friends such as Conor Clune of Quin in November 1920 and the subsequent devastating raids on his farm result in his playing a far more active role in Sinn Féin as a loyal supporter of the new TD for Clare, Éamon de Valera. For this he is imprisoned following his return from Britain as part of a Sinn Féin delegation which is publicising the Black and Tans atrocities.
Edgeworth is the son of Richard Edgeworth senior, and great-grandson of Sir Salathiel Lovell through his mother, Jane Lovell, granddaughter of Sir Salathiel. The Edgeworth family comes to Ireland in the 1580s. He is descended from Francis Edgeworth, appointed joint Clerk of the Crown and Hanaper in 1606, who inherits a fortune from his brother Edward Edgeworth, Bishop of Down and Connor.
A Trinity College, Dublin and Corpus Christi College, Oxford alumnus, Edgeworth is credited for creating, among other inventions, a machine to measure the size of a plot of land. He also makes strides in developing educational methods. He anticipates the caterpillar track with an invention that he plays around with for forty years but never successfully develops. He describes it as a “cart that carries its own road.”
Edgeworth is married four times, including both Honora Sneyd and Frances Beaufort, older sister of Francis Beaufort of the Royal Navy. He is the father of 22 children by his four wives. Beaufort and he install a semaphore line for Ireland. He is a member of the Lunar Society of Birmingham. The Lunar Society evolves through various degrees of organization over a period of years but is only ever an informal group. No constitution, minutes, publications or membership lists survive from any period, and evidence of its existence and activities is found only in the correspondence and notes of those associated with it. Dates given for the society range from sometime before 1760 to it still operating as late as 1813. Fourteen individuals have been identified as having verifiably attended Lunar Society meetings regularly over a long period during its most productive time: these are Matthew Boulton, Erasmus Darwin, Thomas Day, Richard Lovell Edgeworth, Samuel Galton, Jr., James Keir, Joseph Priestley, William Small, Jonathan Stokes, James Watt, Josiah Wedgwood, John Whitehurst and William Withering.
Conway is remembered for his application of biquaternion algebra to the special theory of relativity. He publishes an article in 1911, and in 1912 asserts priority over Ludwik Silberstein, who also applies biquaternions to relativity. This claim is backed up by George Temple in his book 100 Years of Mathematics. In 1947 Conway puts quaternions to use with rotations in hyperbolic space. The next year he publishes quantum mechanics applications which are referred to in a PhD thesis by Joachim Lambek in 1950.
Conway continues his scholarship in the field of mathematics and theoretical physics and makes a special study of William Rowan Hamilton. With John Lighton Synge, he edits the first volume of Hamilton’s mathematical papers, and, with A. J. McConnell, he edits the second volume of Hamilton’s mathematical papers. Conway is also active in college life, being appointed Registrar, a position he occupies until his election as president in 1940. He retires in 1947 from the presidency of UCD. In 1953, some of his writings are edited by J. McConnell for publication by the Dublin Institute for Advanced Studies.
