On August 21, 2015, Google announces a major investment of €150 million to build a new two‑story data centre alongside its existing facility at Profile Park, Grangecastle, West Dublin. This marks Google’s second major data centre investment in Ireland and is part of its ongoing expansion of cloud computing infrastructure.
The new facility is designed to support Google’s global fleet of cloud computing facilities, with a focus on building the world’s most energy‑efficient computing network. The expansion is completed in phases, with the groundbreaking in 2018 for the €150 million project, which takes about 16 months to build.
Google’s economic and employment impact includes over €750 million in capital assets in Ireland since 2003, with the new centre adding to that total. At peak construction, the project creates around 400 jobs; by completion, Google’s Irish operations employ 6,000 people (direct and contracted). A 2018 Copenhagen Economics report estimates the Irish data centre operations supports 4,900 jobs and contributes €400 million to Ireland’s gross domestic product (GDP) between 2011 and 2017.
TaoiseachEnda Kenny describes the opening as “a new chapter” in Google’s story in Ireland, noting the company’s role as a leader in the country’s digital community. Minister Mary Mitchell O’Connor welcomes the investment as proof of Ireland’s competitive advantage for high‑tech companies and its skilled workforce. Ministers Heather Humphreys and Pat Breen call it a “vote of confidence” in Ireland’s business environment and a testament to the country’s technical expertise and infrastructure.
The Grange Castle site becomes a key hub for Google’s EMEA (Europe, the Middle East and Africa) operations, with engineering teams in Dublin central to the company’s global efficiency goals. The investment reinforces Ireland’s position as a major European data centre location, benefiting not only Google but also the broader Irish tech and business ecosystem.
In summary, the August 2015 announcement is the start of a significant infrastructure and employment boost for Ireland, with the completed €150 million expansion solidifying Google’s long‑term commitment to the country’s digital economy.
Antisell is born in Dublin on January 16, 1817, the youngest son of Thomas Christopher Antisell KC (home circuit) and Margaret (née) Daly. He attends the Dublin School of Medicine, the Apothecaries’ Hall of Ireland, and the Royal College of Surgeons of England in London, graduating from the latter with an MD in November 1839. He studies chemistry in Paris and Berlin in 1844. Upon his return to Dublin in 1845, he secures a lectureship in botany at the Peter St. School of Medicine, teaching there until 1848. After this, he opens a clinic at his residence of 25 Richmond Street, Portobello. He works as an assistant to Robert Kane, and between 1845 and 1847, produces textbooks on Irish geology and chemistry. He becomes a member of the Royal Dublin Society (RDS) in 1844.
Antisell is a member of the Young Ireland movement of the 1840s, and joins the Irish Confederation in 1847. With a group of five friends in the republican movement, including Richard D’Alton Williams and Kevin O’Doherty, he sets up a short-lived revolutionary newspaper, The Irish Tribune, in June 1848 to take the place of the suppressed United Irishman, founded by John Mitchel. The paper is closed down on the grounds of sedition in July 1848 after just five issues. Following the closure of the paper, he emigrates to the United States, arriving in New York City on November 22, 1848. Some sources claim this departure is to evade arrest or charges relating to sedition. Although he is no longer politically active following his departure from Ireland, he is a close friend of John Mitchel and his family. He marries his first wife, Eliza Ann Nowlan, in 1841. She dies shortly after their arrival in the United States.
Antisell sets up and operates a clinic and medical laboratory in New York City from 1848 to 1854, while also lecturing in chemistry in a number of medical colleges in Massachusetts and Vermont. He takes up a post as expedition geologist and botanist on state surveys in southern Arizona, New Mexico, and California, working primarily with Lt. John Parke investigating the proposed routes for the Southern Pacific Railroad from 1854 to 1856. His work on the geology of the region adds to greater understanding of the science in America. In 1856, he is employed as chief examiner in the U.S. Patent Office in Washington, D.C., with responsibility for chemical inventions. This work allows him to also lecture in chemistry at Georgetown University, eventually covering other subjects such as toxicology, military surgery, physiology, hygiene, and pathology, over the periods 1858 to 1869, and 1880 to 1882.
Breaking with Mitchel who, as defender of slavery, supports the southern secessionist cause, Antisell serves in the Union Army during the American Civil War. He is a brigade surgeon in the United States Volunteers from 1861, and later the medical director of the 12th army corps. He concludes his service as surgeon-in-charge of Harewood Hospital, Washington, D.C., in October 1865, being granted a brevet commission as colonel. From 1866 to 1871, he is chief chemist in the U.S. Department of Agriculture. He marries his second wife, Marion Stuart Forsyth from Detroit, in 1854. They go on to have twelve children, six daughters and six sons.
Antisell is one of several scientists that are hired in 1871 as foreign government advisors to work in Hokkaido in northern Japan under Horace Capron. He is selected for his strong background in chemistry coupled with geology. However, he disagrees with Capron on whether or not Hokkaido’s severe winter climate will hinder development, and he also comes into conflict with the Japanese government over his salary. As a result, Hokkaido Colonisation Office hires another geologist, and Antisell’s report is excluded in the 1875 compilation of official reports. He serves his remaining time in Japan as a chemist for the Ministry of Finance, where he develops inks used for the printing of paper currency. For his services, he is awarded the Order of the Rising Sun by Emperor Meiji before his departure in 1876.
Upon returning to the United States, Antisell is conferred with a PhD in 1876 by Georgetown University, and once again takes up duties at the Patent Office, remaining there until his retirement. He publishes widely in numerous journals on topics such as agricultural chemistry, botany, oceanography, city sanitation, and animal disease, but he does not publish a significant treatise.
Antisell dies in Washington, D.C., on June 14, 1893, and is buried in the Congressional Cemetery.
Stoney is the younger son of George Stoney and Anne Blood, second daughter of Bindon Blood of Cranagher and Rockforest, County Clare. His brother is the physicistGeorge Johnstone Stoney, known for coining the term electron for the fundamental unit of electricity. He is also the uncle of another Irish physicist George Francis FitzGerald, the son of his sister Anne Frances. His nieces are Edith Anne Stoney, a pioneer medical physicist, and Florence Stoney, the first female radiologist in the United Kingdom. Both serve in hospitals near the front line during World War I.
Stoney is privately educated at home while his father’s properties lose value in the post-Napoleonic depression and are sold during the famine of 1845–49. He then attends Trinity College Dublin (TCD), where in 1850 he obtains his BA and a diploma in civil engineering with distinction. He marries Susannah Frances Walker on October 7, 1879; they have four children.
Bindon’s career in engineering commences when he works on surveys for the Aranjuez to Almansa railway in Spain from 1852 to 1853. Upon returning to Ireland in 1854, he is appointed as resident engineer under James Barton on the Boyne railway viaduct until its completion in 1855. This viaduct claims to have the longest span in the world and has the world’s longest girders at the time.
Bindon’s groundbreaking work building a metal bridge with a span of such dimensions using shock-absorbent wrought-iron latticed bars instead of a continuity of plate with Barton is possibly the first of its kind. It is the basis for his later two-volume publication The theory of strains in girders and similar structures, with observations on the strength and other properties of materials (1866), nicknamed “Stoney on strains” and reproduced in two further editions.
Bindon becomes an associate of the Institution of Civil Engineers (ICE) in January 1858 and a full member in November 1863.
In 1856, Bindon is appointed as assistant engineer to George Halpin, Jr. at the Ballast Board on Westmoreland Street and in 1859 he is appointed as Executive Engineer. He is ambitious and an engineering innovator who comes up with a cheap way to develop the Dublin Port – something appreciated by the board but they also do not want to upset Halpin. When Halpin retires, Stoney becomes the new inspector of works and in 1868, becomes the first chief engineer of the newly constituted Dublin Port and Docks Board.
Bindon designs a large dredging plant and rebuilds nearly 7,000 feet of quay walls along both north and south banks of the River Liffey, replacing the tidal berths by deep water berths. Additionally, the northern quays are lengthened eastward and the formation of Alexandra Basin begins in 1871 and is partially completed by 1885. In addition to harbour works, he is in charge of the design and construction of two major bridges that cross the River Liffey. In 1872–1875 he largely rebuilds Essex Bridge, designed in the 1750s by George Semple to his own flamboyant design. It is renamed Grattan Bridge after Henry Grattan. In 1877–80 he redesigns the 1790s Carlisle Bridge of James Gandon, renamed O’Connell Bridge after Daniel O’Connell, to provide a crossing linking Sackville (later O’Connell) Street with the converging streets to the south. He builds a new iron swing bridge in 1877–1879, just west of The Custom House named Beresford Bridge.
Stoney invents a diving bell, and means to use precast concrete. Toward the end of his career, he erects the North Bull Lighthouse (1877–80) to replace the inadequate light on the Bull Wall marking the northern side of the Dublin port channel entrance opposite Poolbeg Lighthouse before finally retiring in 1898.
Synge is born on June 1, 1890, in south Dublin, to Edward Synge and Ellen Frances Price. He is familiarly known as “Hutchie.” He is the nephew of playwrightJohn Millington Synge and the older brother of distinguished mathematician and theoretical physicist John Lighton Synge who edits the collected works of Sir William Rowan Hamilton at Synge’s urging. He and brother John are great-great-great-grandsons of Irish bishopHugh Hamilton. He is also the uncle of the mathematician Cathleen Synge Morawetz. Throughout his life he is very physically active, pursuing walking, cycling, swimming and sailing. In his later life, he takes up painting and is quite good at it.
In 1908, Synge enters Trinity College Dublin (TCD) to study Mathematics and Old Irish. For three years he is a brilliant student and wins several prizes and a Foundation Scholarship in mathematics in 1910. At the end of his third year, he comes into an inheritance from his uncle John Millington Synge, and in 1913 he drops out of university.
Starting in 1928, with encouragement from Albert Einstein, Synge launches on a period of intense productivity during which he lays the foundation for new kinds of microscopes and telescopes. Nobody, including his famous brother John, appreciates his achievements at the time. His work is overlooked for decades, but is now better-known thanks to the book The Life and Works of Edward Hutchinson Synge published by Living Edition in 2012.
On April 22, 1928, Synge writes to Einstein about an idea he has for a new microscopic imaging method in which an optical field scattered from a tiny gold particle can be used as a radically new light source. Einstein replies that although Synge’s method appears essentially unworkable, the basic ideas seem correct and he should publish his research.
There follows a remarkable period from 1928 to 1932 in which Synge produces all of his key works which he publishes in the Dublin Philosophical Magazine and Journal of Science. Remarkably, he does all of this work alone, without a laboratory, and while living at his home in Dundrum in the suburbs of Dublin. By 1932 he has laid out the theory of the near-field microscope and his description is incredibly accurate.
The idea is ahead of its time. In 1956, a similar theory is developed by John A. O’Keefe and in 1972, Eric Ash gives the first experimental demonstration of the technique using electromagnetic radiation. It is not until Synge’s original papers re-emerge in the 1980s that his priority is finally recognised.
Synge proposes a design for very large astronomical telescopes, based on multiple mirrors, an idea realised much later in Tucson, Arizona, and elsewhere. He also invents a new kind of remote sensing technique using searchlights. Today this is known as Lidar and uses pulsed lasers.
According to the people who know him best, Synge suffers from what today would be called Asperger syndrome. Becoming increasingly socially isolated, he drops out of university in 1913 and works alone without any support from the academic community until all work stops in 1932. In 1936, he has a mental breakdown and is committed to a Dublin nursing home where he remains until his death on May 26, 1957. He is buried with his parents in Dublin’s Mount Jerome Cemetery, with only a few relatives attending. It is much later that his niece, Cathleen Synge Morawetz, arranges to have “Scientist and Inventor” inscribed on the gravestone.
Hamilton enters Trinity College Dublin on November 17, 1742, at the age of 13 with Thomas McDonnell as his tutor. He graduates Bachelor of Arts (BA) in 1747 and Trinity Master of Arts (MA Dubl) in 1750. He takes the competitive examination for a vacant fellowship of the college in 1750, but the position is secured instead by his friend Richard Murray, who is a few years older. Two fellowships become vacant the following year and Hamilton is elected to one of them at the age of 22. He is appointed Erasmus Smith’s Professor of Natural and Experimental Philosophy at Trinity College Dublin in 1759 and that same year graduates Bachelor of Divinity (BD). He is elected a Fellow of the Royal Society on February 19, 1761, and graduates Doctor of Divinity (DD) in 1762.
Trinity College presents him to the rectory of Kilmacrennan in the diocese of Raphoe, County Donegal, in 1764. This is a small benefice in the gift of the college, for which he resigns his fellowship. He retains the Erasmus Smith’s chair, however, being succeeded in that by Thomas Wilson in 1769. He resigns from Kilmacrenan in 1767 and becomes vicar of St. Ann’s Church in Dublin.
Hamilton then becomes Dean of Armagh, the chief resident cleric of St. Patrick’s Cathedral in Armagh, County Armagh, from April 1768 to 1796. Finding the existing dean’s house inconvenient and poorly situated, he has a new one built in a better location just off Portadown Road, now known as Dean’s Hill. The house, of three stories and a semi-basement, is built in 1772–74. The house is later sold by the church and the present owners provide bed and breakfast accommodation in it. While dean he also acts as treasurer for the infirmary or county hospital, he establishes Sunday schools in the districts of the parish, and he founds a charitable loan for poor tradesmen. He is also instrumental in planning a piped water supply for the town, which is later put into effect. He is one of the 38 original members of the Royal Irish Academy when it is founded in 1785. Gilbert Stuart paints his portrait in about 1790 (pictured above).
Hamilton is promoted to Bishop of Clonfert and Kilmacduagh on January 20, 1796, without seeking it. On January 24, 1799, he is translated to Ossory, where he is bishop until 1805. He dies of a fever at Kilkenny, County Kilkenny, on December 1, 1805. He is buried in the graveyard of St. Canice’s Cathedral at Kilkenny, and there is a memorial to him inside the cathedral.
Hamilton writes a mathematical treatise on conic sections called De Sectionibus Conicis: Tractatus Geometricus, published in 1758. In this book he “was the first to deduce the properties of the conic section from the properties of the cone, by demonstrations which were general, unencumbered by lemmas, and proceeding in a more natural and perspicuous order,” according to writer James Wills in 1847. The work is acclaimed for its lucidity and Leonhard Euler describes it as a perfect book. It is “soon adopted in all the British universities” and is translated from Latin into English as A Geometrical Treatise of the Conic Sections in 1773.
Hamilton also writes Philosophical Essays on Vapours (1767), Four Introductory Lectures on Natural Philosophy (1774), and An Essay on the Existence and Attributes of the Supreme Being (1784). His principal works are collected and republished, with a memoir, as The Works of the Right Rev. Hugh Hamilton by his eldest son, Alexander Hamilton, in two volumes in 1809.
Hamilton marries Isabella, daughter of Hans Widman Wood of Rosmead, County Westmeath, in 1772. Isabella’s mother Frances is the twin sister of Edward King, 1st Earl of Kingston. They have five sons and two daughters. They are Alexander, who was a barrister; Frances; Hans, who is rector of Knocktopher, County Kilkenny, and associated with the Carrickshock incident of 1831; Isabella; Henry; George, who is a biblical scholar; and Hugh, who marries Elizabeth Staples, a daughter of John Staples, a Member of Parliament. The younger Hugh is the great-grandfather of Clive Staples Lewis, better known as C. S. Lewis. Bishop Hugh Hamilton is a great-great-great-grandfather of the mathematicians John Lighton Synge and his brother Edward Hutchinson Synge. Dodgson Hamilton Madden, the High Court judge and noted scholar, is Hamilton’s great-grandson.

George Johnstone StoneyFRS, Irish physicist, is born on February 15, 1826, at Oakley Park, near Birr, County Offaly, in the Irish Midlands. 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 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 in Notting Hill, on July 5, 1911. His cremated ashes are buried in St. Nahi’s Church, Dundrum, Dublin.
Callan is born on December 22, 1799, in Darver, County Louth. He attends school at an academy in Dundalk. His local parish priest, Father Andrew Levins, then takes him in hand as an altar boy and Mass server and sees him start the priesthood at Navanseminary. He enters Maynooth College in 1816. In his third year at Maynooth, he studies natural and experimental philosophy under Dr. Cornelius Denvir. He introduces the experimental method into his teaching and has an interest in electricity and magnetism.
Callan is ordained a priest in 1823 and goes to Rome to study at Sapienza University, obtaining a doctorate in divinity in 1826. While in Rome he becomes acquainted with the work of the pioneers in electricity such as Luigi Galvani (1737–98), who is a pioneer in bioelectricity, and Alessandro Volta (1745–1827), who is known especially for the development of the electric battery. In 1826, he returns to Maynooth as the new Professor of Natural Philosophy (now called physics), where he also begins working with electricity in his basement laboratory at the college.
Influenced by William Sturgeon and Michael Faraday, Callan begins work on the idea of the induction coil in 1834. He invents the first induction coil in 1836. An induction coil produces an intermittent high voltagealternating current from a low voltage direct current supply. It has a primary coil consisting of a few turns of thick wire wound around an iron core and subjected to a low voltage (usually from a battery). Wound on top of this is a secondary coil made up of many turns of thin wire. An iron armature and make-and-break mechanism repeatedly interrupts the current to the primary coil, producing a high voltage, rapidly alternating current in the secondary circuit.
Callan invents the induction coil because he needs to generate a higher level of electricity than currently available. He takes a bar of soft iron, about 2 feet long, and wraps it around with two lengths of copper wire, each about 200 feet long. He connects the beginning of the first coil to the beginning of the second. Finally, he connects a battery, much smaller than the enormous contrivance just described, to the beginning and end of winding one. He finds that when the battery contact is broken, a shock can be felt between the first terminal of the first coil and the second terminal of the second coil.
Further experimentation shows how the coil device can bring the shock from a small battery up the strength level of a big battery. So Callan tries making a bigger coil. With a battery of only 14 seven-inch plates, the device produces power enough for an electric shock “so strong that a person who took it felt the effects of it for several days.” He thinks of his creation as a kind of electromagnet, but what he actually makes is a primitive induction transformer.
Callan’s induction coil also uses an interrupter that consists of a rocking wire that repeatedly dips into a small cup of mercury (similar to the interrupters used by Charles Grafton Page). Because of the action of the interrupter, which can make and break the current going into the coil, he calls his device the “repeater.” Actually, this device is the world’s first transformer. He induces a high voltage in the second wire, starting with a low voltage in the adjacent first wire. The faster he interrupts the current, the bigger the spark. In 1837 he produces his giant induction machine using a mechanism from a clock to interrupt the current 20 times a second. It generates 15-inch sparks, an estimated 60,000 volts and the largest artificial bolt of electricity then seen.
Callan experiments with designing batteries after he finds the models available to him at the time to be insufficient for research in electromagnetism. Some previous batteries had used rare metals such as platinum or unresponsive materials like carbon and zinc. He finds that he can use inexpensive cast iron instead of platinum or carbon. For his Maynooth battery he uses iron casting for the outer casing and places a zinc plate in a porous pot (a pot that had an inside and outside chamber for holding two different types of acid) in the centre. Using a single fluid cell, he disposes of the porous pot and two different fluids. He is able to build a battery with just a single solution.
While experimenting with batteries, Callan also builds the world’s largest battery at that time. To construct this battery, he joins together 577 individual batteries (“cells“), which use over 30 gallons of acid. Since instruments for measuring current or voltages have not yet been invented, he measures the strength of a battery by measuring how much weight his electromagnet can lift when powered by the battery. Using his giant battery, his electromagnet lifts 2 tons. The Maynooth battery goes into commercial production in London. He also discovers an early form of galvanisation to protect iron from rusting when he is experimenting on battery design, and he patents the idea.
Callan dies at the age of 64 in Maynooth, County Kildare, on January 10, 1864. He is buried in the cemetery in St. Patrick’s College, Maynooth.
The Callan Building on the north campus of Maynooth University, a university which is part of St. Patrick’s College until 1997, is named in his honour. In addition, Callan Hall in the south campus, is used through the 1990s for first year science lectures including experimental & mathematical physics, chemistry and biology. The Nicholas Callan Memorial Prize is an annual prize awarded to the best final year student in Experimental Physics.
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.
Colleran, and her twin Noreen, are born in Ballinrobe, County Mayo, on October 12, 1945, to John and Josie Colleran. One of a family of five children, her father is a school principal and her mother, also a primary school teacher, dies when she is just 11 years old. She completes her secondary education at St. Louis secondary school in Kiltimagh. She spends a lot of time outdoors as a child, particularly fishing, which sparks her interest in the environment.
On entering higher education, Colleran has a grant from the Department of Education, which requires that she do her studies through the Irish language. Her first choice, Medicine, is not available in Irish so she chooses Science. She graduates with a first-class primary degree in Science at University College Galway (now National University of Ireland, Galway) in 1967.
Colleran lectures in biology at Athlone Regional Technical College (now Athlone Institute of Technology) and Galway Regional Technical College (now Galway-Mayo Institute of Technology) before her appointment as a lecturer in microbiology at NUI Galway in 1976. She is appointed Associate Professor of Microbiology by the Senate of the National University of Ireland in 1990. She is a member of the university’s governing authority for a number of years, but steps down in May 2000 in connection with the selection procedure for the new university president. In October of that year, she is appointed professor of microbiology and chair of the department at NUI Galway.
Colleran is the first director of the Environment Change Institute at NUI Galway set up under the Higher Education Authority‘s Programme for Research in Third Level Institutions in 2000. In 2010, the Environmental Change Institute and the Martin Ryan Marine Research Institute are merged to form the current day Ryan Institute at NUI Galway.
In 1973, Colleran is elected to the committee of the Galway Association of An Taisce, part of a national voluntary organisation the aims of which are conservation in Ireland through education, publicity and positive action. She serves as membership secretary and then treasurer to the Galway branch before becoming chairman. In 1981, as chairman of the Galway branch, she hits back at claims from Galway County Council that An Taisce are “an anonymous group, wielding power unfairly.” She is involved in the compilation of a controversial planning report, published by An Taisce in 1983, which highlights abuse of planning laws by city and county councillors across Ireland, and in particular in counties Galway, Mayo, Donegal, Kerry and Louth.
Colleran serves as Environmental Officer for An Taisce before being elected National Chairman in 1987, the first time a chairman has come from one of the western county associations. She continues to use her position to campaign against misuse of planning laws, for a clamp down on pollution of rivers and lakes, and against a move to scrap An Foras Forbartha, a body that provides independent monitoring of pollution. During her three years as chairman, until May 1990, she is particularly involved in debates over local environmental and planning issues, in particular over gold mining in the west of Ireland, a proposed airport for Clifden, and the planned sewage treatment plant at Mutton Island, County Galway.
In 1991 plans are announced for a new visitor centre, to be located at Mullaghmore in The Burren. Colleran is among those who are part of an appeal, saying that while the plan for the national park is welcomed by An Taisce, they want the visitor centre to be located three or four miles from Mullaghmore.
President Mary Robinson appoints seven new members to her Council of State in February 1991, including Colleran. Other new members appointed at the time are Monica Barnes, Patricia O’Donovan, Quintan Oliver, Rosemarie Smith, Dónal Toolan and D. Kenneth Whitaker. The new Council of State represents a wide spectrum of Irish life and is widely welcomed, although Fine Gael is disappointed that its leader John Bruton is not included.
In 1991, Colleran is one of 15 people appointed to TaoiseachCharles Haughey‘s Green 2000 Advisory Group, to determine which problems will face the environment in the next century. The group is led by Dr. David Cabot, special advisor on environmental affairs.
In 2003, Colleran is elected as a member of the Royal Irish Academy.
Colleran is recognised at the annual NUI Galway Alumni Awards in 2004 when she receives the award for Natural Science, sponsored by Seavite Bodycare Ltd., which acknowledges a graduate who has made an outstanding contribution in the field of natural science.
Mitchell’s family moves to Belfast while he is a child. He receives his formal education at Belfast Academy where he excels in mathematics. He begins to notice that his eyesight is failing. By the age of 16 he can no longer read and by the age of 22 he is completely blind.
Undeterred, Mitchell borrows £100 and starts up a successful business making bricks in the Ballymacarrett area of Belfast. This enables him to start building his own houses and he completes approximately twenty in the city. It is during this period that his talent for inventing comes to the fore and he fabricates several machines for use in brickmaking and the building trade.
Mitchell patents the screw pile in 1833, for which he later gains some fame. The screw-pile is used for the erection of lighthouses and other structures on mudbanks and shifting sands, including bridges and piers. His designs and methods are employed all over the world from the Portland, Mainebreakwater to bridges in Bombay. Initially it is used for the construction of lighthouses on Maplin Sands in the Thames Estuary in 1838, at Fleetwood Lancashire (UK) Morecambe Bay in 1839 and at Belfast Lough where his lighthouse is finished in July 1844.
In May 1851 Mitchell moves to Cobh to lay the foundation for the Spit Bank Lighthouse. The success of these undertakings leads to the use of his invention on the breakwater at Portland, the viaduct and bridges on the Bombay, Baroda and Central India Railway and a broad system of Indian telegraphs.
Mitchell dies at Glen Devis near Belfast on June 25, 1868, and is buried in the old Clifton graveyard in Belfast. His wife and daughter predecease him.
