Dowden is the son of John Wheeler Dowden, a merchant and landowner, and is born three years after his brother John, who becomes Bishop of Edinburgh in 1886. His literary tastes emerge early, in a series of essays written at the age of twelve. His home education continues at Queen’s College, Cork and at Trinity College, Dublin. He contributes to the literary magazine Kottabos.
Dowden has a distinguished career, becoming president of the University Philosophical Society, and wins the vice-chancellor’s prize for English verse and prose, and the first senior moderatorship in ethics and logic. In 1867 he is elected professor of oratory and English literature in Dublin University.
Dowden’s first book, Shakespeare: A Critical Study of His Mind and Art (1875), results from a revision of a course of lectures, and makes him widely known as a critic: translations appear in German and Russian; his Poems (1876) goes into a second edition. His Shakespeare Primer (1877) is translated into Italian and German. In 1878 the Royal Irish Academy awards him the Cunningham gold medal “for his literary writings, especially in the field of Shakespearian criticism.”
Later works by Dowden in this field include an edition of The Sonnets of William Shakespeare (1881), Passionate Pilgrim (1883), Introduction to Shakespeare (1893), Hamlet (1899), Romeo and Juliet (1900), Cymbeline (1903), and an article entitled “Shakespeare as a Man of Science” (in the National Review, July 1902), which criticizes T. E. Webb’s Mystery of William Shakespeare. His critical essays “Studies in Literature” (1878), “Transcripts and Studies” (1888), “New Studies in Literature” (1895) show a profound knowledge of the currents and tendencies of thought in various ages and countries; but his The Life of Percy Bysshe Shelley (1886) makes him best known to the public at large. In 1900 he edits an edition of Shelley‘s works.
Other books by Dowden which indicate his interests in literature include: Southey (1879), his edition of Southey’s Correspondence with Caroline Bowles (1881), and Select Poems of Southey (1895), his Correspondence of Sir Henry Taylor (1888), his edition of William Wordsworth‘s Poetical Works (1892) and of his Lyrical Ballads (1890), his French Revolution and English Literature (1897), History of French Literature (1897), Puritan and Anglican (1900), Robert Browning (1904) and Michel de Montaigne (1905). His devotion to Johann Wolfgang von Goethe leads to his succeeding Max Müller in 1888 as president of the English Goethe Society.
In 1889 Dowden gives the first annual Taylorian Lecture at the University of Oxford, and from 1892 to 1896 serves as Clark lecturer at Trinity College, Cambridge. To his research are due, among other matters of literary interest, the first account of Thomas Carlyle‘s Lectures on periods of European culture; the identification of Shelley as the author of a review (in The Critical Review of December 1814) of a romance by Thomas Jefferson Hogg; a description of Shelley’s Philosophical View of Reform; a manuscript diary of Fabre d’Églantine; and a record by Dr Wilhelm Weissenborn of Goethe’s last days and death. He also discovers a Narrative of a Prisoner of War under Napoleon (published in Blackwood’s Magazine), an unknown pamphlet by Bishop George Berkeley, some unpublished writings of William Hayley relating to William Cowper, and a unique copy of the Tales of Terror.
Dowden’s wide interests and scholarly methods make his influence on criticism both sound and stimulating, and his own ideals are well described in his essay on The Interpretation of Literature in his Transcripts and Studies. As commissioner of education in Ireland (1896–1901), trustee of the National Library of Ireland, secretary of the Irish Liberal Union and vice-president of the Irish Unionist Alliance, he enforces his view that literature should not be divorced from practical life. His biographical/critical concepts, particularly in connection with Shakespeare, are played with by Stephen Dedalus in the library chapter of James Joyce‘s Ulysses. Leslie Fiedler is to play with them again in The Stranger in Shakespeare.
Dowden marries twice, first to Mary Clerke in 1866, and secondly in 1895 to Elizabeth Dickinson West, daughter of the dean of St Patrick’s. His daughter by his first wife, Hester Dowden, is a well-known spiritualist medium.
Dowden dies in Dublin on April 4, 1913. His Letters are published in 1914 by Elizabeth and Hilda Dowden.
A Dublin City Council plaque commemorating Dowden is unveiled on November 29, 2016.
Long comes from a carpentry and blacksmithing background. In 1959, he enters Queen’s University Belfast to study civil engineering. He graduates with first class honours and then takes a PhD at Queens. In 1967, he moves to Canada, working as a bridge designer for Fenco Engineering in Toronto.
Long, however, spends only a year in Canada, returning to Belfast in 1968 to become an associate professor of civil engineering at Queen’s University Belfast. In 1976, he is promoted to a full professorship. His work is largely in the field of concrete structures, particularly in chloride resistance, maintenance problems and arch bridge structures. He publishes twenty papers in journals managed by the Institution of Civil Engineers and wins eight of the institution’s medals for these, including the ICE Gold Medal.
From 1997 Long works on the FlexiArch, a precast concrete arch in which the individual voussoirs are joined by a flexible polymeric membrane. The arch arrives to site flat packed and when lifted into position by a crane, the gaps between the voussoirs close under gravity and form the correct arch profile. He patents the product, which is produced by Irish precast manufacturer Macrete, in 2004. The product can be constructed within a day and, containing no corrodible elements, has been stated to have a design lifespan of 300 years. More than fifty FlexiArch bridges have been constructed in the UK and Ireland and spans up to 30m are possible.
By 2002, Long is appointed dean of the faculty of engineering at QUB. In November of that year, he is appointed president of the ICE for the 2002–2003 session, the first Northern Irish person to hold that position. He is also a Fellow of the Royal Academy of Engineering and of the Institute for the Advancement of Engineering.
Long is appointed an officer of the Order of the British Empire in the 2006 New Year Honours for services to higher education and civil engineering. He resigns as professor at QUB in 2006 but remains there as an emeritus professor in the School of Natural and Built Environment. Since 2015, the ICE Northern Ireland awards the Adrian Long medal to the best paper in an ICE journal to be authored by a Northern Ireland member. The medal features a bust of Long.
O’Connell had rejected a suggestion from “friends of emancipation,” and from the English Roman Catholic bishop, John Milner, that the fear of Catholic advancement might be allayed if the Crown were accorded the same right exercised by continental monarchs: a veto on the confirmation of Catholic bishops. O’Connell insists that Irish Catholics would rather “remain forever without emancipation” than allow the government “to interfere” with the appointment of their senior clergy. Instead, he relies on their confidence in the independence of the priesthood from Ascendancy landowners and magistrates to build his Catholic Association into a mass political movement. On the basis of a “Catholic rent” of a penny a month (typically paid through the local priest), the Association mobilises not only the Catholic middle class, but also poorer tenant farmers and tradesmen. Their investment enables O’Connell to mount “monster” rallies that stay the hands of authorities, and embolden larger enfranchised tenants to vote for pro-emancipation candidates in defiance of their landlords.
O’Connell’s campaign reaches its climax when he himself stands for parliament. In July 1828, he defeats a nominee for a position in the British cabinet, William Vesey-FitzGerald, in a County Clare by-election, 2057 votes to 982. This makes a direct issue of the parliamentary Oath of Supremacy by which, as a Catholic, he will be denied his seat in the Commons.
As Lord Lieutenant of Ireland, Wellington’s brother, Richard Wellesley, had attempted to placate Catholic opinion, notably by dismissal of the long-serving Attorney-General for Ireland, William Saurin, whose rigid Ascendancy views and policy made him bitterly unpopular, and by applying a policy of prohibitions and coercion against not only the Catholic Ribbonmen but also the Protestant Orangemen. But now both Wellington and his Home Secretary, Robert Peel, are convinced that unless concessions are made, a confrontation is inevitable. Peel concludes, “though emancipation was a great danger, civil strife was a greater danger.” Fearing insurrection in Ireland, he drafts the Relief Bill and guides it through the House of Commons. To overcome the vehement opposition of both the King and of the House of Lords, Wellington threatens to resign, potentially opening the way for a new Whig majority with designs not only for Catholic emancipation but also for parliamentary reform. The King initially accepts Wellington’s resignation and the King’s brother, Ernest Augustus, Duke of Cumberland, attempts to put together a government united against Catholic emancipation. Though such a government would have considerable support in the House of Lords, it would have little support in the Commons and Ernest abandons his attempt. The King recalls Wellington. The bill passes the Lords and becomes law.
The key, defining, provision of the Acts is its repeal of “certain oaths and certain declarations, commonly called the declarations against transubstantiation and the invocation of saints and the sacrifice of the mass, as practised in the Church of Rome,” which had been required “as qualifications for sitting and voting in parliament and for the enjoyment of certain offices, franchises, and civil rights.” For the Oath of Supremacy, the act substitutes a pledge to bear “true allegiance” to the King, to recognise the Hanoverian succession, to reject any claim to “temporal or civil jurisdiction” within the United Kingdom by “the Pope of Rome” or “any other foreign prince … or potentate,” and to “abjure any intention to subvert the present [Anglican] church establishment.”
This last abjuration in the new Oath of Allegiance is underscored by a provision forbidding the assumption by the Roman Church of episcopal titles, derived from “any city, town or place,” already used by the United Church of England and Ireland. (With other sectarian impositions of the Act, such as restrictions on admittance to Catholic religious orders and on Catholic-church processions, this is repealed with the Roman Catholic Relief Act 1926.)
The one major security required to pass the Act is the Parliamentary Elections (Ireland) Act 1829. Receiving its royal assent on the same day as the relief bill, the act disenfranchises Ireland’s forty-shilling freeholders, by raising the property threshold for the county vote to the British ten-pound standard. As a result, “emancipation” is accompanied by a more than five-fold decrease in the Irish electorate, from 216,000 voters to just 37,000. That the majority of the tenant farmers who had voted for O’Connell in the Clare by-election are disenfranchised as a result of his apparent victory at Westminster is not made immediately apparent, as O’Connell is permitted in July 1829 to stand unopposed for the Clare seat that his refusal to take the Oath of Supremacy had denied him the year before.
In 1985, J. C. D. Clark depicts England before 1828 as a nation in which the vast majority of the people still believed in the divine right of kings, and the legitimacy of a hereditary nobility, and in the rights and privileges of the Anglican Church. In Clark’s interpretation, the system remained virtually intact until it suddenly collapsed in 1828, because Catholic emancipation undermined its central symbolic prop, the Anglican supremacy. He argues that the consequences were enormous: “The shattering of a whole social order. … What was lost at that point … was not merely a constitutional arrangement, but the intellectual ascendancy of a worldview, the cultural hegemony of the old elite.”
Clark’s interpretation has been widely debated in the scholarly literature, and almost every historian who has examined the issue has highlighted the substantial amount of continuity before and after the period of 1828 through 1832.
Eric J. Evans in 1996 emphasises that the political importance of emancipation was that it split the anti-reformers beyond repair and diminished their ability to block future reform laws, especially the great Reform Act of 1832. Paradoxically, Wellington’s success in forcing through emancipation led many Ultra-Tories to demand reform of Parliament after seeing that the votes of the rotten boroughs had given the government its majority. Thus, it was an ultra-Tory, George Spencer-Churchill, Marquess of Blandford, who in February 1830 introduced the first major reform bill, calling for the transfer of rotten borough seats to the counties and large towns, the disfranchisement of non-resident voters, the preventing of Crown officeholders from sitting in Parliament, the payment of a salary to MPs, and the general franchise for men who owned property. The ultras believed that a widely based electorate could be relied upon to rally around anti-Catholicism.
In Ireland, emancipation is generally regarded as having come too late to influence the Catholic-majority view of the union. After a delay of thirty years, an opportunity to integrate Catholics through their re-emerging propertied and professional classes as a minority within the United Kingdom may have passed. In 1830, O’Connell invites Protestants to join in a campaign to repeal the Act of Union and restore the Kingdom of Ireland under the Constitution of 1782. At the same, the terms under which he is able to secure the final measure of relief may have weakened his repeal campaign.
George Ensor, a leading Protestant member of the Catholic Association in Ulster, protests that while “relief” bought at the price of “casting” forty-shilling freeholders, both Catholic and Protestant, “into the abyss,” might allow a few Catholic barristers to attain a higher grade in their profession, and a few Catholic gentlemen to be returned to Parliament, the “indifference” demonstrated to parliamentary reform will prove “disastrous” for the country.
Seeking, perhaps, to rationalise the sacrifice of his freeholders, O’Connell writes privately in March 1829 that the new ten-pound franchise might actually “give more power to Catholics by concentrating it in more reliable and less democratically dangerous hands.” The Young IrelanderJohn Mitchel believes that the intent is to detach propertied Catholics from the increasingly agitated rural masses.
In a pattern that had been intensifying from the 1820s as landlords clear land to meet the growing livestock demand from England, tenants have been banding together to oppose evictions and to attack tithe and process servers.
Browne is an important and outspoken member of the Irish hierarchy. His time as Bishop has been described by the historian James S. Donnelly Jr. as “far-reaching and … controversial,” while the historian of Irish CatholicismJohn Henry Whyte claims that Browne’s “readiness to put forward his views bluntly is welcome at least to the historian.”
On August 6, 1937, at the relatively young age of 41, Browne is appointed Bishop of Galway and Kilmacduagh by Pope Pius XI, receiving his episcopal consecration from Archbishop Thomas Gilmartin on the following August 10. He supports TaoiseachÉamon de Valera‘s defence of arrests and police searches for cached Irish Republican Army (IRA) arms, declaring, “Any Irishman who assists any foreign power to attack the legitimate authority of his own land is guilty of the most terrible crime against God’s law, and there can be no excuse for that crime – not even the pretext of solving partition or of securing unity.”
In 1939, Browne is selected by Éamon de Valera to chair the Commission on Vocational Organisation.
Browne is attentive to the state of public morality in the diocese, and James S. Donnelly Jr. has noted his role in directing episcopal and clerical censorship of newsagents and county librarians. He is also concerned about public intoxication and other misconduct at the Galway Races, controversies over dancing and the commercial dance halls, as well as immodesty in dress and the closely related issue of so-called “mixed bathing” in Galway and Salthill.
In 1957, in response to a growing tension between Catholics and Protestants at Fethard-on-Sea, including the Fethard-on-Sea boycott, Browne says, “non-Catholics do not protest against the crime of conspiring to steal the children of a Catholic father, but they try to make political capital when a Catholic people make a peaceful and moderate protest.”
The most enduring monument or physical legacy of Browne’s time as Bishop is the Cathedral of Our Lady Assumed into Heaven and St Nicholas, commonly known as Galway Cathedral, which is dedicated in 1965 by CardinalRichard James Cushing of Boston, Massachusetts. The site of the old jail had come into the possession of the diocese in 1941 and Browne leads the campaign to construct a new Cathedral. This includes a 1957 audience with Pope Pius XII where the plans are approved.
Browne attends the Second Vatican Council from 1962 to 1965 and retires in 1976. He dies four years later, at the age of 84, on February 24, 1980.
Browne is parodied in Breandán Ó hÉithir`s novel Lig Sinn i gCathu, which fictionalises late 1940s Galway as “Baile an Chaisil” and Browne as “An tEaspag Ó Maoláin.”
The Irish cabinet minister Noël Browne (no known relation) in his 1986 memoir Against the Tide describes the physical attributes of his episcopal namesake:
“The bishop had a round soft baby face with shimmering clear cornflower-blue eyes, but his mouth was small and mean. Around his great neck was an elegant glinting gold episcopal chain with a simple pectoral gold cross. He wore a ruby ring on his plump finger and wore a slightly ridiculous tiny scullcap on his noble head. The well-filled semi-circular scarlet silk cummerbund and sash neatly divided the lordly prince into two.”
Purser is born in Dublin on August 24, 1835, the son of John Tertius Purser (1809–1893), the general manager of the well-known A Guinness, Son & Co. brewery, and Anna Benigna Fridlezius (1803-1881). He is educated in a wealthy family, which includes artists, as his cousin Sarah Purser, or engineers, as his brother-in-law John Purser Griffith. He is the brother of mathematician Frederick Purser. He receives his early education at the private boarding school run by his uncle, Dr. Richard W. Biggs, at Devizes, Wiltshire. He completes his schooling at Devizes and begins his university studies at Trinity College, Dublin, graduating BA in mathematics in 1856. He is the best mathematician of his year at the University and in 1855 he gains the Lloyd Exhibition.
Purser becomes a tutor to the four sons of William Parsons, 3rd Earl of Rosse (1800-1867) in 1857. Lord Rosse’s 72-inch reflecting telescope, built in 1845 and colloquially known of as the “Leviathan of Parsonstown,” is the world’s largest telescope when it is built and continues to hold this distinction until the early 20th century. As well as acting as tutor to the children, Purser does become involved in Lord Rosse’s interest in astronomy but never does any observing.
In 1863, Purser is appointed professor of mathematics at Queen’s College, Belfast, a position he maintains until his retirement in 1901.
Purser never marries. When his father dies on April 5, 1893, Rathmines Castle passes to him. He dies at Rathmines Castle on October 18, 1903, a very wealthy man. In his will he leaves £100,000 to his brother Frederick Purser, £40,000 to his sister Anna Griffith and £5,000 to each of her children. In addition to the money, he owns property in Blessington Street, Essex Street and Eustace Street which he leaves to his brother-in-law John Purser Griffith. Other properties and interests that he owns he divides between his brother Frederick and his sister Anna. After his death, his sister Anna and her husband John Purser Griffith move into Rathmines Castle although, at this time, its ownership has gone to Frederick Purser. After Frederick dies in August 1910, the Castle and his considerable wealth passes to Anna.

Cohalan is an outspoken critic during the Irish War of Independence, condemning acts of violence on both sides. In particular, he denounces the policy of reprisals. In July 1920, he pronounces an interdict on the killers of a Royal Irish Constabulary (RIC) sergeant, shot dead in the church porch in Bandon. He declares that anyone killing from ambush will be excommunicated. On December 12, 1920, Cohalan issues a decree saying that “anyone within the diocese of Cork who organises or takes part in ambushes or murder, or attempted murder, shall be excommunicated.” In turn, his life is threatened by the Irish Republican Army (IRA). In August 1928, he condemns the British government which had allowed Terence MacSwiney to die on hunger strike in 1920.
The Bessborough Home in Cork is run by the Sisters of the Sacred Hearts of Jesus and Mary and when the department “sought a change of superior in Bessborough because of the appallingly high death rate, he [Catholic Bishop of Cork Dr. Daniel Cohalan] denounced the request. The replacement of the Bessborough superior was delayed for four years after the department requested it, and many infants died during that time. It seems probable that the bishop’s intervention was elicited by the congregation.” In general, the report finds that the major causes of infant mortality in the homes were respiratory infections and gastroenteritis, while “public attention has focused on marasmus [malnutrition]” suggesting “willful neglect.” However, it says that “the term marasmus is best seen as indicating that a child was failing to thrive, but medical experts suggest that this was due to an underlying, undiagnosed medical condition.”
Cohalan dies in office at the age of 94 at Bon Secours Hospital, Cork, on August 24, 1952. A story, current at the time in Cork, refers to his antipathy towards bishops of the Church of Ireland who styled themselves “Bishop of Cork.” A month before his death, and on his deathbed, word is brought to him of the death of the Church of Ireland Bishop of Cork, Cloyne and Ross, Robert Hearn. The response of Cohalan, known “affectionately” as “Danny Boy”, is reputedly, “now he knows who’s Bishop of Cork.”

James Augustine Healy, American Roman Catholic priest and the second bishop of Portland, Maine, is born on April 6, 1830, in Macon, Georgia to a multiracial slave mother and Irish immigrant father. He is the first bishop in the United States of any known African descent. When he is ordained in 1854, his multiracial ancestry is not widely known outside his mentors in the Catholic Church.
Healy is the eldest of ten siblings of Michael Morris Healy, an Irish immigrant planter from County Roscommon, and his common law wife Eliza Smith (sometimes recorded as Clark), a multiracial enslaved African American. He achieves many “firsts” in United States history. He is credited with greatly expanding the Catholic church in Maine at a time of increased Irish immigration. He also serves Abenaki people and many parishioners of French-Canadian descent who were traditionally Catholic. He speaks both English and French.
Beginning in 1837, like many other wealthy planters with mixed-race children, Michael Healy starts sending his sons to school in the North. James, along with brothers Hugh and Patrick, goes to Quaker schools in Flushing, New York, and Burlington, New Jersey. Later they each attend the newly opened College of the Holy Cross in Worcester, Massachusetts. He graduates as valedictorian of the college’s first graduating class in 1849.
Following graduation, Healy wishes to enter the priesthood. He cannot study at the Jesuit novitiate in Maryland, as it is a slave state. With the help of John Bernard Fitzpatrick, he enters a Sulpicianseminary in Montreal. In 1852, he transfers to study at Saint-Sulpice Seminary in Paris, working toward a doctorate and a career as a seminary professor. After a change of heart, he decides to become a pastor. On June 10, 1854, he is ordained at Notre-Dame de Paris as a priest to serve in Boston, Massachusetts. He is the first African American to be ordained a Roman Catholic priest although at the time he identifies as and is accepted as white Irish Catholic.
When Healy returns to the United States, he becomes an assistant pastor in Boston. He serves the archbishop, who helps establish his standing in the church. In 1866 he becomes the pastor of St. James Church, the largest Catholic congregation in Boston. In 1874 when the Boston legislature is considering taxation of churches, he defends Catholic institutions as vital organizations that help the state both socially and financially. He also condemns certain laws that are generally enforced only on Catholic institutions. He founds several Catholic charitable institutions to care for the many poor Irish immigrants who had arrived during the Great Famine years.
Healy’s success in the public sphere leads to his appointment by Pope Pius IX to the position of second bishop of Portland, Maine. He is consecrated as Bishop of Portland on June 2, 1875, becoming the first African American to be consecrated a Catholic bishop. For 25 years he governs his large diocese, supervising also the founding of the Diocese of Manchester, New Hampshire, when it is split from Portland in 1885. During his time in Maine, which is a period of extensive immigration from Catholic countries, he oversees the establishment of 60 new churches, 68 missions, 18 convents, and 18 schools. During that period, he also serves his Abenaki and French-Canadian parishioners.
Healy is the only member of the American Catholic hierarchy to excommunicate men who joined the Knights of Labor, a national union, which reaches its peak of power in 1886.
Dixon is the youngest of the seven sons of George Dixon, a soap manufacturer, and Rebecca (née Yeates) Dixon. He is educated at Rathmines School and Trinity College, Dublin. In 1894, after studying in Bonn, Germany, he is appointed assistant and later full Professor of Botany at Trinity. In 1906 he becomes Director of the Botanic Gardens and in 1910 of the Herbarium also. He has a close working relationship with physicist John Joly and together they develop the cohesion theory of the ascent of sap.
Dixon’s early research includes work on the cytology of chromosomes and first mitosis in certain plants. Familiarity with work on transpiration and on the tensile strength of columns of sulfuric acid and water leads Dixon and Joly to experiment on transpiration. “On the Ascent of Sap” (1894) presents the hypothesis that the sap or water in the vessels of a woody plant ascends by virtue of its power of resisting tensile stress and its capacity to remain cohesive under the stress of great differences of pressure. Dixon and Joly further demonstrate that water is transported through passive vessels and not living cells.
Dixon writes Transpiration and the Ascent of Sap in Plants (1914), which brings various theories and experimental works together in a coherent argument. He also writes a textbook, Practical Plant Biology (1922).
In 1907 Dixon marries Dorothea Mary, daughter of Sir John H. Franks, with whom he raises three sons. He is the father of biochemistHal Dixon and grandfather of Adrian Dixon and Joly Dixon.
