Parsons also performs some preliminary work in association with the practices of the electrodeposition of copper sulfate upon silver films circa 1865 while in search of the design for a truly flat mirror to use in a telescope. However, he finds it impossible to properly electroplate copper upon these silver films, as the copper contracts and detaches from the underlying glass substrate. His note has been cited as one of the earliest confirmations in literature that thin films on glass substrates experience residual stresses. He revives discussion in his work Nature’s August 1908 edition after witnessing similar techniques used to present newly devised searchlights before the Royal Society.
Although overshadowed by his father (when astronomers speak of “Lord Rosse”, it is almost always the father that they refer to), Parsons nonetheless pursues some astronomical observations of his own, particularly of the Moon. Most notably, he discovers NGC 2, a spiral galaxy in the constellationPegasus.
After some years of ill-health, Parsons dies on August 30, 1908, at Birr Castle and is buried in the local churchyard. He leaves a bequest to the Royal Society to establish the “Rosse Fund,” and a further £1,000 to the science school fund at TCD.
George Johnstone StoneyFRS, Irish physicist, dies on July 5, 1911, at Notting Hill, London, England. He is most famous for introducing the term “electron” as the “fundamental unit quantity of electricity.” He introduces the concept, though not the word, as early as 1874, initially naming it “electrine,” and the word itself comes in 1891. He publishes around 75 scientific papers during his lifetime.
Stoney is born on February 15, 1826, at Oakley Park, near Birr, County Offaly, in the Irish Midlands, the son of George Stoney and Anne (née Bindon Blood). His only brother is Bindon Blood Stoney, who becomes chief engineer of the Dublin Port and Docks Board. The Stoney family is an old-established Anglo-Irish family. During the time of the famine (1845–52), when land prices plummet, the family property is sold to support his widowed mother and family. He attends Trinity College Dublin (TCD), graduating with a BA degree in 1848. From 1848 to 1852 he works as an astronomy assistant to William Parsons, 3rd Earl of Rosse, at Birr Castle, County Offaly, where Parsons had built the world’s largest telescope, the 72-inch Leviathan of Parsonstown. Simultaneously he continues to study physics and mathematics and is awarded an MA by TCD in 1852.
From 1852 to 1857, Stoney is professor of physics at Queen’s College Galway. From 1857 to 1882, he is employed as Secretary of the Queen’s University of Ireland, an administrative job based in Dublin. In the early 1880s, he moves to the post of superintendent of Civil Service Examinations in Ireland, a post he holds until his retirement in 1893. He continues his independent scientific research throughout his decades of non-scientific employment duties in Dublin. He also serves for decades as honorary secretary and then vice-president of the Royal Dublin Society (RDS), a scientific society modeled after the Royal Society of London and, after his move to London in 1893, he serves on the council of that society as well. Additionally, he intermittently serves on scientific review committees of the British Association for the Advancement of Science from the early 1860s.
Stoney publishes seventy-five scientific papers in a variety of journals, but chiefly in the journals of the Royal Dublin Society. He makes significant contributions to cosmic physics and to the theory of gases. He estimates the number of molecules in a cubic millimeter of gas, at room temperature and pressure, from data obtained from the kinetic theory of gases. His most important scientific work is the conception and calculation of the magnitude of the “atom of electricity.” In 1891, he proposes the term “electron” to describe the fundamental unit of electrical charge, and his contributions to research in this area lays the foundations for the eventual discovery of the particle by J. J. Thomson in 1897.
Stoney proposes the first system of natural units in 1881. He realizes that a fixed amount of charge is transferred per chemical bond affected during electrolysis, the elementary chargee, which can serve as a unit of charge, and that combined with other known universal constants, namely the speed of lightc and the Newtonian constant of gravitationG, a complete system of units can be derived. He shows how to derive units of mass, length, time and electric charge as base units. Due to the form in which Coulomb’s law is expressed, the constant 4πε0 is implicitly included, ε0 being the vacuum permittivity.
Like Stoney, Max Planck independently derives a system of natural units (of similar scale) some decades after him, using different constants of nature.
Hermann Weyl makes a notable attempt to construct a unified theory by associating a gravitational unit of charge with the Stoney length. Weyl’s theory leads to significant mathematical innovations, but his theory is generally thought to lack physical significance.
Stoney marries his cousin, Margaret Sophia Stoney, by whom he has had two sons and three daughters. One of his sons, George Gerald Stoney FRS, is a scientist. His daughter Florence StoneyOBE is a radiologist while his daughter Edith is considered to be the first woman medical physicist. His most scientifically notable relative is his nephew, the Dublin-based physicist George Francis FitzGerald. He is second cousin of the grandfather of Ethel Sara Turing, mother of Alan Turing.
After moving to London, Stoney lives first at Hornsey Rise, north London, before moving to 30 Chepstow Crescent, Notting Hill, west London. In his later years illness confines him to a single floor of the house, which is filled with books, papers, and scientific instruments, often self-made. He dies at his home on July 5, 1911. His cremated ashes are buried in St. Nahi’s Church, Dundrum, Dublin.
In September 1966, Coveney goes to work in the English-language section of the Secretariat of State in the Vatican. This sometimes involves acting as interpreter at audiences of Pope Paul VI, as when the Pope receives the three astronauts of the Apollo 11 mission that first lands human beings on the Moon.
Coveney serves with the rank of Secretary in the Apostolic Nunciature in Buenos Aires from 1972 to 1976, returning then to the Secretariat of State in the Vatican. He is counselor of the nunciatures in New Delhi (1982–1984) and Khartoum (1984–1985).
On January 25, 1990, Coveney is appointed Nuncio to Ethiopia and also becomes Apostolic Delegate to Djibouti on March 26, 1992, and Nuncio to Eritrea on September 30, 1995.
Coveney becomes Apostolic Nuncio to New Zealand, Tonga, the Marshall Islands, and Samoa, and Apostolic Delegate for Oceania on hpril 27, 1996. His remit is expanded to include Apostolic Nuncio to Fiji, Kiribati, the Federated States of Micronesia, and Vanuatu on October 15, 1996, and Apostolic Nuncio to Nauru on December 7, 1996. He is also named Apostolic Nuncio to the Cook Islands and Palau on July 14, 2001. As the longest-serving resident diplomatic representative to New Zealand, Archbishop Coveney serves for a time as Dean of the Diplomatic Corps. While based in Wellington, he also represents the Holy See at the inauguration of Chen Shui-bian as president of the Republic of China (Taiwan) on May 18, 2004.
Coveney’s last diplomatic appointment is as Apostolic Nuncio to Greece on January 25, 2005. On November 5, 2008, he officiates at the presentation to the Acropolis Museum in Athens of a fragment of the Parthenon Frieze on loan from the Vatican Museums. He resides in Athens until his retirement in 2009.
Coveney returns to the Diocese of Cork and Ross to reside in Crosshaven Parish. He assists in Crosshaven parish and celebrates the Sacrament of Confirmation in many parishes throughout the Diocese of Cork and Ross. He dies at the age of 88 on October 22, 2022.

Reverend John Thomas Romney Robinson, 19th-century astronomer and physicist usually referred to as Thomas Romney Robinson, was born at St. Anne’s in Dublin on April 23, 1792. He is the longtime director of the Armagh Observatory, one of the chief astronomical observatories in the United Kingdom at the time. He is remembered as the inventor in 1846 of the Robinson 4-cup anemometer, a device for measuring the speed of the wind.
Robinson is the son of the English portrait painter Thomas Robinson (d.1810) and his wife, Ruth Buck (d.1826). He is educated at Belfast Academy then studies Divinity at Trinity College Dublin, where he is elected a Scholar in 1808, graduating BA in 1810 and obtaining a fellowship in 1814, at the age of 22. He is for some years a deputy professor of natural philosophy (physics) at Trinity.
In 1823, at the age of 30, Robinson gains the appointment of astronomer at the Armagh Observatory. From this point on he always resides at the Armagh Observatory, engaged in research connected with astronomy and physics, until his death in 1882. Having also been ordained as an Anglican priest while at Trinity, he obtains the church livings of the Anglican Church at Enniskillen and at Carrickmacross in 1824.
During the 1840s and 1850s Robinson is a frequent visitor to the world’s most powerful telescope of that era, the so-called Leviathan of Parsonstown telescope, which had been built by Robinson’s friend and colleague William Parsons, 3rd Earl of Rosse. He is active with Parsons in interpreting the higher-resolution views of the night sky produced by Parsons’ telescope, particularly with regard to the galaxies and nebulae and he publishes leading-edge research reports on the question.
Back at his own observatory in Armagh, Robinson compiles a large catalogue of stars and writes many related reports. In 1862 he is awarded a Royal Medal “for the Armagh catalogue of 5345 stars, deduced from observations made at the Armagh Observatory, from the years 1820 up to 1854; for his papers on the construction of astronomical instruments in the memoirs of the Astronomical Society, and his paper on electromagnets in the Transactions of the Royal Irish Academy.”
Robinson is president of the Royal Irish Academy from 1851 to 1856 and is a long-time active organiser in the British Association for the Advancement of Science. He is a friend of Charles Babbage, who says was “indebted” for having reminded him about the first time he came up with the idea of the calculating machine.
Robinson marries twice, first to Eliza Isabelle Rambaut (d.1839) and secondly to Lucy Jane Edgeworth (1806–1897), the lifelong disabled daughter of Richard Lovell Edgeworth. His daughter marries the physicist George Gabriel Stokes. Stokes frequently visits Robinson in Armagh in Robinson’s later years.
Robinson dies in Armagh, County Armagh at the age of 89 on February 28, 1882.
The crater Robinson on the Moon is named in his honour.
McClure is the posthumous son of one of James Abercrombie‘s captains, first cousin of Oscar Wilde and spends his childhood under the care of his godfather, General John Le Mesurier, governor of Alderney, by whom he is educated for the army. The McClures are of Highland Scots ancestry, being a sept of Clan MacLeod of Harris. He enters the navy, however, in 1824, and twelve years later gains his first experience of Arctic exploration as mate of HMS Terror in the expedition (1836–1837) commanded by Captain George Back.
Upon his return he obtains his commission as lieutenant, and from 1838 to 1839 serves on the Canadian lakes, being subsequently attached to the North American and West Indian naval stations, where he remains until 1846. Two years later he joins John Franklin‘s search expedition (1848–1849) under James Clark Ross as first lieutenant of HMS Enterprise.
After he returns from the first Franklin search expedition, a new search expedition is launched in 1850, with Richard Collinson commanding the HMS Enterprise and McClure, as his subordinate, given the command of HMS Investigator. The two ships set out from England, sail south on the Atlantic Ocean, navigate through the Strait of Magellan to the Pacific Ocean with the assistance of steam-sloop HMS Gorgon, where they become separated and have no further contact for the rest of their respective journeys.
The HMS Investigator sails north through the Pacific and enters the Arctic Ocean by way of the Bering Strait, and sails eastward past Point Barrow, Alaska to eventually link up with another British expedition from the northwest. Although the HMS Investigator is abandoned to the pack ice in the spring of 1853, McClure and his crew are rescued by a party from the HMS Resolute, one of the ships under the command of Sir Edward Belcher that are sailing from the east, after a journey over the ice by sledge. Subsequently he completes his journey across the Northwest Passage. HMS Resolute itself does not make it out of the Arctic that year and is abandoned in ice, but later recovered. The wood from that ship becomes quite famous later.
Thus, McClure and his crew are the first both to circumnavigate the Americas, and to transit the Northwest Passage, considerable feats at that time. The HMS Enterprise, meanwhile, having arrived at Point Barrow in 1850 a fortnight later than the HMS Investigator, finds its passage blocked by winter ice and has to turn back and return the following year.
Upon his return to England, in 1854, McClure is court martialed for the loss of the HMS Investigator, which is automatic when a captain loses his ship. Following an honourable acquittal, he is knighted and promoted to post-rank, his commission being dated back four years in recognition of his special services. McClure and his crew share a great monetary reward of £10,000 awarded them by the British Parliament. He subsequently is also awarded gold medals by the English and French geographical societies. In 1855 he is elected a member of the American Antiquarian Society.
From 1856 to 1861 McClure serves in Eastern waters, commanding the division of the Naval Brigade before Canton in 1858, for which he receives a CB in the following year. His latter years are spent in a quiet country life. He attains the rank of rear admiral in 1867, and of vice admiral in 1873. He dies on October 17, 1873 and is buried in Kensal Green Cemetery, London.
