Birth of Bindon Blood Stoney, Civil Engineer

Bindon Blood Stoney FRS, a civil engineer who also makes some significant contributions to astronomy, is born on June 13, 1828, at Oakley Park, King’s County (now County Offaly).

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 physicist George 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.

In 1850–52, prior to beginning his engineering work, Stoney assists William Parsons, 3rd Earl of Rosse at Parsonstown. There he accurately maps the spiral form of the Andromeda Galaxy and observes 105 New General Catalogue (NGC) objects and 8 Index Catalogues (IC) objects. Ninety-one of the NGC objects and all of the IC objects are new. On March 1, 1851, he discovers the spiral galaxy NGC 5609, which is the most distant visually observed galaxy in the NGC catalogue.

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.

Stoney is admitted to the Royal Irish Academy (RIA) in 1857. He is given an honorary degree by University College Dublin (UCD) in recognition of his achievements and is later elected President of the Institution of Engineers of Ireland in 1871. In 1874, he is awarded the Telford Medal and Telford premium of the Institution of Civil Engineers for a paper documenting his work on the northern quays. He is elected Fellow of the Royal Society on June 2, 1881.

Stoney dies in Dublin on May 5, 1909, and he is buried in Mount Jerome Cemetery. Stoney Road in East Wall is named after him.

Birth of Astronomer William Parsons, 3rd Earl of Rosse

William Parsons, 3rd Earl of Rosse, Anglo-Irish astronomer, naturalist, and engineer, is born in York, England on June 17, 1800. He is President of the Royal Society (UK), the most important association of naturalists in the world in the nineteenth century. He builds several giant telescopes. His 72-inch telescope, built in 1845 and colloquially known as the “Leviathan of Parsonstown,” is the world’s largest telescope, in terms of aperture size, until the early 20th century. From April 1807 until February 1841, he is styled as Baron Oxmantown.

Parsons is the son of Lawrence Parsons, 2nd Earl of Rosse, and Alice Lloyd. He is educated at Trinity College, Dublin and Magdalen College, Oxford, graduating with first-class honours in mathematics in 1822. He inherits an earldom and a large estate in King’s County (now County Offaly) in Ireland when his father dies in February 1841.

Parsons marries Mary Field, daughter of John Wilmer Field, on April 14, 1836. They have thirteen children, of which four sons survive to adulthood: Lawrence, 4th Earl of Rosse, Rev. Randal Parsons, the Hon. Richard Clere Parsons, and the Hon. Sir Charles Algernon Parsons.

In addition to his astronomical interests, Parsons serves as a Member of Parliament (MP) for King’s County from 1821 to 1834, president of the British Science Association in 1843–1844, an Irish representative peer after 1845, president of the Royal Society (1848–1854), and chancellor of Trinity College, Dublin (1862–1867).

During the 1840s, Parsons has the Leviathan of Parsonstown built, a 72-inch telescope at Birr Castle, Parsonstown, County Offaly. He has to invent many of the techniques he uses for constructing the Leviathan, both because its size is without precedent and because earlier telescope builders had guarded their secrets or had not published their methods. Details of the metal, casting, grinding and polishing of the 3-ton ‘speculum’ are presented in 1844 at the Belfast Natural History Society. His telescope is considered a marvelous technical and architectural achievement, and images of it are circulated widely within the British commonwealth. Building of the Leviathan begins in 1842, and it is first used in 1845, with regular use waiting another two years due to the Great Famine. Using this telescope, he sees and catalogues a large number of nebulae, including a number that would later be recognised as galaxies.

Parsons performs astronomical studies and discovers the spiral nature of some nebulas, today known to be spiral galaxies. His telescope Leviathan is the first to reveal the spiral structure of M51, a galaxy nicknamed later as the “Whirlpool Galaxy,” and his drawings of it closely resemble modern photographs.

Parsons dies at the age of 67 on October 31, 1867, at Monkstown, County Dublin.

Parsons’s son publishes his father’s findings, including the discovery of 226 New General Catalogue of Nebulae and Clusters of Stars (NGC) objects in the publication Observations of Nebulae and Clusters of Stars Made With the Six-foot and Three-foot Reflectors at Birr Castle From the Year 1848 up to the Year 1878, Scientific Transactions of the Royal Dublin Society Vol. II, 1878.
