Birth of Robert Mallet, the Father of Seismology

Robert Mallet, geophysicist, civil engineer, and inventor who distinguishes himself in research on earthquakes and is sometimes called the Father of Seismology, is born in Dublin on June 3, 1810.

Mallet is the son of factory owner John Mallet. He is educated at Trinity College, Dublin, entering it at the age of 16 and graduating in science and mathematics in 1830 at the age of 20.

Following his graduation, Mallet joins his father’s iron foundry business and helps build the firm into one of the most important engineering works in Ireland, supplying ironwork for railway companies, the Fastnet Rock lighthouse, and a swing bridge over the River Shannon at Athlone. He also helps manufacture the characteristic iron railings that surround Trinity College, and which bear his family name at the base.

Mallet is elected to the Royal Irish Academy in 1832 at the early age of 22. He also enrolls in the British Association for the Advancement of Science in 1835 which helps finance much of his research in seismology.

In 1838 Mallet becomes a life member of the Royal Geological Society of Ireland and serves as its President from 1846–1848. From 1848–1849 he constructs the Fastnet Rock lighthouse, southwest of Cape Clear.

On February 9, 1846, Mallet presents to the Royal Irish Academy his paper On the Dynamics of Earthquakes, which is considered to be one of the foundations of modern seismology. He is also credited with coining the word “seismology” and other related words which he uses in his research. He also coins the term epicentre.

From 1852 to 1858, Mallet is engaged in the preparation of his work, The Earthquake Catalogue of the British Association (1858) and carries out blasting experiments to determine the speed of seismic propagation in sand and solid rock.

On December 16, 1857, the area around Padula, Italy is devastated by the Great Neapolitan earthquake which causes 11,000 deaths. At the time it is the third largest known earthquake in the world and has been estimated to have been of magnitude 6.9 on the Richter Scale. Mallet, with letters of support from Charles Lyell and Charles Darwin, petitions the Royal Society of London and receives a grant of £150 to go to Padula and record at first hand the devastation. The resulting report is presented to the Royal Society as the Report on the Great Neapolitan Earthquake of 1857. It is a major scientific work and makes great use of the then new research tool of photography to record the devastation caused by the earthquake. In 1862, he publishes the Great Neapolitan Earthquake of 1857: The First Principles of Observational Seismology in two volumes. He brings forward evidence to show that the depth below the Earth’s surface, from where the impulse of the Neapolitan earthquake originated, is about 8–9 geographical miles.

One of Mallet’s papers is Volcanic Energy: An Attempt to develop its True Origin and Cosmical Relations, in which he seeks to show that volcanic heat may be attributed to the effects of crushing, contortion, and other disturbances in the crust of the earth. The disturbances leading to the formation of lines of fracture, more or less vertical, down which water would find its way, and if the temperature generated be sufficient volcanic eruptions of steam or lava would follow.

Mallet is elected Fellow of the Royal Society in 1854, and in 1861 moves to London, where he becomes a consulting engineer and edits The Practical Mechanic’s Journal. He is awarded the Telford Medal by the Institution of Civil Engineers in 1859, followed by the Cunningham Medal of the Royal Irish Academy for his research into the theory of earthquakes in 1862, and the Wollaston Medal of the Geological Society of London in 1877, the Geological Society’s highest award.

Blind for the last seven years of his life, Robert Mallet dies at Stockwell, London, on November 5, 1881, and is buried at West Norwood Cemetery.

Birth of Sir William Napier, Soldier & Historian

Sir William Francis Patrick Napier, a soldier in the British Army and a military historian, is born on December 17, 1785, at Castletown, near Celbridge, County Kildare.

Napier is the third son of Colonel George Napier and his second wife, Lady Sarah Lennox, seventh daughter of Charles Lennox, 2nd Duke of Richmond, and previously wife of Sir Charles Thomas Bunbury, MP. His elder brothers are General Sir Charles James Napier (1782–1853), the conqueror of Sindh, and General Sir George Thomas Napier (1784–1855), governor of the Cape Colony. He is a first cousin of Charles James Fox and also of Lord Edward FitzGerald.

Educated locally, he enters the British Army as an ensign in the Royal Irish Regiment of Artillery on June 14, 1800. Transferring to the 62nd (Wiltshire) Regiment of Foot, he is promoted to lieutenant on April 18, 1801, but is placed on half pay at the Treaty of Amiens in March 1802. He is promoted to captain in June 1804, transferring to the 43rd (Monmouthshire) Regiment of Foot in August, and in 1806 is sent to Ireland on a recruiting tour, with instructions to recruit men from the militia to serve in the line regiments. In July 1807 he serves with his regiment under the command of General Arthur Wellesley during the successful Second Battle of Copenhagen and is present at the Battle of Køge.

In September 1808 Napier sails with his regiment to Spain, where he serves throughout the Peninsular campaign of Gen. Sir John Moore. He is present at many of the major actions of the later campaigns, including the Combat of the Côa in July 1810, where he is wounded, the Battle of Bussaco on September 27, 1810, and the actions at Pombal and Redinha. At the action at Casal Novo on March 14, 1811, he is severely wounded while leading forward six companies of the 52nd (Oxfordshire) Regiment of Foot in an effort to harass the rearguard of André Masséna‘s army. He later returns to the army, with his wound still open and a bullet lodged near his spine, and is appointed as brigade major to the Portuguese brigade. He takes part in the Battle of Fuentes de Oñoro on May 3-5, 1811, and is promoted to major at the end of the month.

Succumbing to fever, Napier returns to England. During a period of leave, he marries his cousin, Caroline Amelia Fox, daughter of General Henry Edward Fox and niece of Charles James Fox in February 1812. After his leave he returns to Portugal and takes command of the 43rd (Monmouthshire) Regiment of Foot as senior major present. He subsequently serves in the battles of Salamanca on July 22, 1812, Nivelle on November 10, 1813, and Nive on December 10-13, 1813, which is Marshal Jean-de-Diew Soult‘s last attempt to drive the allied army from France. Promoted to lieutenant-colonel in November 1813, he is present at the Battle of Orthez on February 27, 1814, but has to return to England due to wounds and illness. He is subsequently awarded the gold and silver Peninsular medal, with two and three clasps respectively. Arriving too late in France in 1815, he takes no part in the ‘Hundred days’ campaign and retires from the active list in 1819. He is made a Knight Commander of the Order of the Bath (KCB) in the same year.

Napier devotes the rest of his life to historical writing, initially contributing an article to the Edinburgh Review in 1821. In 1823, at the suggestion of Henry Bickersteth, 1st Baron Langdale, he begins writing his History of the War in the Peninsula and the South of France, 1807–1814 (6 vols., 1828–40). This epic work, which runs to several editions, makes use of material supplied by both the Duke of Wellington and the French marshals Soult and Suchet, while papers of Joseph Bonaparte, captured after the Battle of Vittoria, are also made available to him. In July 1830 he is promoted to full colonel. Promoted to major-general in November 1841, he is appointed Lieutenant Governor of Guernsey (1842–47). Appointed colonel of the 27th (Inniskilling) Regiment of Foot in February 1848, he is made a KCB in May 1848.

Napier later publishes several works centred on his brother, Gen. Sir Charles James Napier, after the latter resigns as commander-in-chief in India. These include History of Sir Charles James Napier’s Administration of Scinde (1851) and Life and Opinions of General Sir Charles James Napier (4 vols., 1857). As both of these works seek to vindicate his brother, they are generally seen to be biased in the extreme. Subsequently promoted to lieutenant-general on November 11, 1851, and general on October 17, 1859, he spends his later years troubled by ill health. He dies on February 12, 1860, at his London residence, Scinde House in Clapham, and is buried at West Norwood Cemetery.

There is a fine marble statue of Napier in St. Paul’s Cathedral, London. His letters are in the Bodleian Library, University of Oxford.
