Regency Personalities Series-Thomas Maclear

Regency Personalities Series

In my attempts to provide us with the details of the Regency, today I continue with one of the many period notables.

Sir Thomas Maclear
17 March 1794 – 14 July 1879

Thomas Maclear

Sir Thomas Maclear was born in Newtownstewart, County Tyrone, Ireland, the eldest son of Rev. James Maclear and Mary Magrath. In 1808 he was sent to England to be educated in the medical profession. After passing his examinations, in 1815 he was accepted into the Royal College of Surgeons of England. He then worked as house-surgeon in the Bedford Infirmary.

In 1823 he went into partnership with his uncle at Biggleswade, Bedfordshire. Two years later in 1825 he was married to Mary Pearse, the daughter of Theed Pearse, Clerk of the Peace for the county of Bedford.

Maclear had a keen interest in amateur astronomy, and would begin a long association with the Royal Astronomical Society, to which he would be named a Fellow. In 1833, when the post became vacant, he was named as Her Majesty’s Astronomer at the Cape of Good Hope, and arrived there aboard the Tam O’Shanter with his wife and 5 daughters, to take up his new duties in 1834. He worked with John Herschel until 1838, performing a survey of the southern sky, and continued to perform important astronomical observations over several more decades. The Maclears and Herschels formed a close friendship, the wives drawn together by the unusual occupations of their husbands and the raising of their large families. Mary Maclear, like Margaret Herschel, was a noted beauty and intelligent, though suffering from extreme deafness.

In 1750, Abbe Nicolas Louis de Lacaille had measured a triangulation meridian arc northwards from Cape Town, to determine the figure of the earth and found that the curvature of the earth was less in southern latitudes than at corresponding northern ones. Sir George Everest visited the Cape in 1820 and visited the site of LaCailles measurements. From his experience in the Himalayas he believed that the presence of considerable mountain masses in the Cape could have caused false measurements to be made by LaCaille. Between 1841 and 1848, Maclear would be occupied in performing a geodesic survey for the purpose of recalculating the dimensions and shape of the Earth. He became close friends with David Livingstone, and they shared a common interest in the exploration of Africa. He performed many other useful scientific activities, including collecting meteorological, magnetic and tide data.

In 1861 his wife died. Two years later he was granted a pension, but did not retire from the observatory until 1870. He lived thereafter at Grey Villa, Mowbray. By 1876, he had lost his sight, and he died three years later in Cape Town, South Africa. He is buried next to his wife on the grounds of the Royal Observatory.

• Knighted in 1860 for his achievements as an astronomer.
• Lalande Prize (1866)
• Royal Medal of the Royal Society (1869), for his measurement of an arc of the meridian in the 1840s.
• The crater Maclear on the Moon is named after him; as is Maclear’s Beacon on Table Mountain; the town of Maclear, in the Eastern Cape of South Africa; and Cape Maclear in Malawi, so named by his friend David Livingstone.

Regency Personalities Series-Prince Augustus Frederick Duke of Sussex

Regency Personalities Series
In my attempts to provide us with the details of the Regency, today I continue with one of the many period notables.

Prince Augustus Frederick Duke of Sussex
27 January 1773 – 21 April 1843

Augustus Frederick

Prince Augustus Frederick Duke of Sussex was the sixth son of George III of the United Kingdom and his consort, Charlotte of Mecklenburg-Strelitz. He was the only surviving son of George III who did not pursue an army or naval career.

Augustus Frederick was born at Buckingham House, London.

He was christened in the Great Council Chamber at St. James’s Palace, on 25 February 1773, by Archbishop of Canterbury Frederick Cornwallis. His godparents were The Duke of Saxe-Gotha-Altenburg (his paternal first cousin once-removed, for whom The Earl of Hertford, Lord Chamberlain, stood proxy), Duke George Augustus of Mecklenburg (his maternal uncle, for whom The Earl of Bristol, Groom of the Stole, stood proxy) and Princess Charles of Hesse-Cassel (his first cousin once-removed, for whom The Viscountess Weymouth, Lady of the Bedchamber to the queen, stood proxy).

He was tutored at home before being sent to the University of Göttingen in Germany in the summer of 1786, along with his brothers Prince Ernest and Prince Adolphus. Prince Augustus, who suffered from asthma, did not join his brothers in receiving military training in Hanover. He briefly considered becoming a cleric in the Church of England.

While travelling in Italy, he met Lady Augusta Murray (1768–1830), the second daughter of 4th Earl of Dunmore. The couple secretly married in Rome on 4 April 1793. The King’s minister of Hanover affairs Ernst zu Münster was sent to Italy, to escort him back to London.

The couple married again without revealing their full identities at St. George’s, Hanover Square, London, on 5 December 1793. Both marriages took place without the knowledge or the consent of the King.

In August 1794, the Prerogative Court annulled the marriage on the grounds that it contravened the Royal Marriages Act 1772 because it had not been approved by the King. Prince Augustus continued to live with Lady Augusta until 1801, when he received a parliamentary grant of £12,000.

Lady Augusta retained custody of the children and received maintenance of £4,000 a year. The two children were named Augustus Frederick D’Este and Ellen Augusta Emma, Mademoiselle D’Este, both parents being descended from the royal House of Este. In 1806 their mother, Lady Augusta, was given royal licence to use the surname D’Ameland instead of Murray.

The King created him Duke of Sussex, Earl of Inverness, and Baron Arklow in the Peerage of the United Kingdom and a Knight of the Garter on 27 November 1801. Since he had no legitimate issue, the title became extinct on his death in 1843. In 1815 The Duke became a Patron of the Jews’ Hospital and Orphan Asylum, later to become the charity known today as Norwood. Royal patronage continued, with Queen Elizabeth II eventually becoming Norwood’s patron.

The Duke of Sussex married a second time on 2 May 1831 (again in contravention of the Royal Marriages Act) to Lady Cecilia Letitia Buggin (1793–1873), the eldest daughter of Arthur Gore, 2nd Earl of Arran and Elizabeth Underwood; and the widow of Sir George Buggin. Even allowing for the irregularity of these marriages, this second marriage would not have been bigamous since Lady Augusta D’Ameland (Lady Augusta Murray) had died the year before. On the same day, Lady Cecilia assumed by Royal Licence the surname Underwood. She was never titled or recognized as the Duchess of Sussex. However, she was created Countess of Inverness in her own right in 1840.

William IV appointed his younger brother Chief Ranger and Keeper of St. James’s and Hyde Parks on 29 January 1831. The Duke of Sussex was elected president of the Society of Arts in 1816 and held that post for the rest of his life. He also held the honorary posts of Captain-General and Colonel of the Hon. Artillery Company from 1817 onward. He was president of the Royal Society between 1830 and 1838, and had a keen interest in biblical studies and Hebrew. In 1838, he introduced in a meeting scientist John Herschel, and the Duke gave a speech in which he spoke about the compatibility of science and religion.

The Duke of Sussex was the favourite uncle of Queen Victoria. He gave her away at her wedding to Prince Albert of Saxe-Coburg-Gotha. The Duke of Sussex died at Kensington Palace in 1843. In his will he specified that he was not to have a state funeral and was accordingly buried at Kensal Green Cemetery on 5 May 1843. He is buried in front of the main chapel, immediately opposite the tomb of his sister, Princess Sophia.

The Countess of Inverness continued to reside at Kensington Palace until her death in 1873. She was buried next to her second husband.

His Children by Lady Augusta Murray

• Augustus Frederick d’Este (1794-1848)

• Augusta Emma de’s (1801-1866) who married Thomas Wilde, 1st Baron Truro

Regency Personalities Series-Sir John Herschel

Regency Personalities Series
In my attempts to provide us with the details of the Regency, today I continue with one of the many period notables.

Sir John Herschel
7 March 1792 – 11 May 1871

John Herschel

Herschel was born in Slough, Berkshire, the son of Mary Baldwin and William Herschel. He studied shortly at Eton College and St John’s College, Cambridge, graduating as Senior Wrangler in 1813. It was during his time as an undergraduate that he became friends with Charles Babbage and George Peacock. He took up astronomy in 1816, building a reflecting telescope with a mirror 18 inches (460 mm) in diameter and with a 20-foot (6.1 m) focal length. Between 1821 and 1823 he re-examined, with James South, the double stars catalogued by his father. For this work, in 1826 he was presented with the Gold Medal of the Royal Astronomical Society (which he won again in 1836), and with the Lalande Medal of the French Academy of Sciences in 1825, while in 1821 the Royal Society bestowed upon him the Copley Medal for his mathematical contributions to their Transactions. Herschel was made a Knight of the Royal Guelphic Order in 1831.

He served as President of the Royal Astronomical Society three times: 1827–1829, 1839–1841 and 1847–1849.

His A preliminary discourse on the study of natural philosophy published early in 1831 as part of Dionysius Lardner’s Cabinet cyclopædia set out methods of scientific investigation with an orderly relationship between observation and theorising. He described nature as being governed by laws which were difficult to discern or to state mathematically, and the highest aim of natural philosophy was understanding these laws through inductive reasoning, finding a single unifying explanation for a phenomenon. This became an authoritative statement with wide influence on science, particularly at the University of Cambridge where it inspired the student Charles Darwin with “a burning zeal” to contribute to this work.

He published a catalogue of his astronomical observations in 1864, as the General Catalogue of Nebulae and Clusters, a compilation of his own work and that of his father’s, expanding on the senior Hershel’s Catalogue of Nebulae. A further complementary volume was published posthumously, as the General Catalogue of 10,300 Multiple and Double Stars.

He also conceptualizes a practical contact lens design in 1823.

Declining an offer from the Duke of Sussex that they travel to South Africa on a Navy ship, Herschel and his wife paid £500 for passage on the S.S. Mountstuart Elphinstone, a ship of 611 tons, which departed from Portsmouth on 13 November 1833. The voyage to South Africa was made in order to catalogue the stars, nebulae, and other objects of the southern skies. This was to be a completion as well as extension of the survey of the northern heavens undertaken initially by his father William Herschel. He arrived in Cape Town on 15 January 1834 and set up a private 21 ft (6.4 m) telescope at Feldhausen at Claremont, a suburb of Cape Town. Amongst his other observations during this time was that of the return of Comet Halley. Herschel collaborated with Thomas Maclear, the Astronomer Royal at the Cape of Good Hope and the members of the two families became close friends.

In addition to his astronomical work, however, this voyage to a far corner of the British empire also gave Herschel an escape from the pressures under which he found himself in London, where he was one of the most sought-after of all British men of science. While in southern Africa, he engaged in a broad variety of scientific pursuits free from a sense of strong obligations to a larger scientific community. It was, he later recalled, probably the happiest time in his life.

In an extraordinary departure from astronomy, he combined his talents with those of his wife, Margaret, and between 1834 and 1838 they produced 131 botanical illustrations of fine quality, showing the Cape flora. Herschel used a camera lucida to obtain accurate outlines of the specimens and left the details to his wife. Even though their portfolio had been intended as a personal record, and despite the lack of floral dissections in the paintings, their accurate rendition makes them more valuable than contemporary collections. Some 112 of the 132 known flower studies were collected and published as “Flora Herscheliana” in 1996.

As their home during their stay in the Cape, the Herschels had selected ‘Feldhausen'(“Field Houses”), an old estate on the south-eastern side of Table Mountain. Here John set up his reflector to begin his survey of the southern skies. Herschel, meanwhile, read widely. Intrigued by the ideas of gradual formation of landscapes set out in Charles Lyell’s Principles of Geology, he wrote to Lyell on 20 February 1836 praising the book as a work that would bring “a complete revolution in [its] subject, by altering entirely the point of view in which it must thenceforward be contemplated” and opening a way for bold speculation on “that mystery of mysteries, the replacement of extinct species by others.” Herschel himself thought catastrophic extinction and renewal “an inadequate conception of the Creator” and by analogy with other intermediate causes, “the origination of fresh species, could it ever come under our cognizance, would be found to be a natural in contradistinction to a miraculous process”. He prefaced his words with the couplet:

He that on such quest would go must know not fear or failing
To coward soul or faithless heart the search were unavailing.
Taking a gradualist view of development and referring to the evolution of language, he commented
“Words are to the Anthropologist what rolled pebbles are to the Geologist — battered relics of past ages often containing within them indelible records capable of intelligent interpretation — and when we see what amount of change 2000 years has been able to produce in the languages of Greece & Italy or 1000 in those of Germany France & Spain we naturally begin to ask how long a period must have lapsed since the Chinese, the Hebrew, the Delaware & the Malesass [Malagasy] had a point in common with the German & Italian & each other — Time! Time! Time! — we must not impugn the Scripture Chronology, but we must interpret it in accordance with whatever shall appear on fair enquiry to be the truth for there cannot be two truths. And really there is scope enough: for the lives of the Patriarchs may as reasonably be extended to 5000 or 50000 years apiece as the days of Creation to as many thousand millions of years.”

The document was circulated, and Charles Babbage incorporated extracts in his ninth and unofficial Bridgewater Treatise, which postulated laws set up by a divine programmer. When HMS Beagle called at Cape Town, Captain Robert FitzRoy and the young naturalist Charles Darwin visited Herschel on 3 June 1836. Later on, Darwin would be influenced by Herschel’s writings in developing his theory advanced in The Origin of Species. In the opening lines of that work, Darwin writes that his intent is “to throw some light on the origin of species — that mystery of mysteries, as it has been called by one of our greatest philosophers”, referring to Herschel.

Herschel returned to England in 1838, was created a baronet, of Slough in the County of Buckingham, and published Results of Astronomical Observations made at the Cape of Good Hope in 1847. In this publication he proposed the names still used today for the seven then-known satellites of Saturn: Mimas, Enceladus, Tethys, Dione, Rhea, Titan, and Iapetus. In the same year, Herschel received his second Copley Medal from the Royal Society for this work. A few years later, in 1852, he proposed the names still used today for the four then-known satellites of Uranus: Ariel, Umbriel, Titania, and Oberon.

Herschel made numerous important contributions to photography. He made improvements in photographic processes, particularly in inventing the cyanotype process and variations (such as the chrysotype), the precursors of the modern blueprint process. In 1839, he made a photograph on glass, which still exists, and experimented with color reproduction, noting that rays of different parts of the spectrum tended to impart their own color to a photographic paper. Herschel made experiments using photosensitive emulsions of vegetable juices, called phytotypes and published his discoveries in the Philosophical Transactions of the Royal Society of London in 1842. He collaborated in the early 1840s with Henry Collen, portrait painter to Queen Victoria. Herschel originally discovered the platinum process on the basis of the light sensitivity of platinum salts, later developed by William Willis.

Herschel coined the term photography in 1839. He may, however, have been preceded by Brazilian Hércules Florence, who used the French equivalent, photographie, in private notes which one historian dates to 1834. Herschel was also the first to apply the terms negative and positive to photography.

He discovered sodium thiosulfate to be a solvent of silver halides in 1819, and informed Talbot and Daguerre of his discovery that this “hyposulphite of soda” (“hypo”) could be used as a photographic fixer, to “fix” pictures and make them permanent, after experimentally applying it thus in early 1839. His ground-breaking research on the subject was read at the Royal Society in London in March 1839 and January 1840.

Herschel wrote many papers and articles, including entries on meteorology, physical geography and the telescope for the eighth edition of the Encyclopædia Britannica. He also translated the Iliad of Homer.

He invented the actinometer in 1825 to measure the direct heating power of the sun’s rays, and his work with the instrument is of great importance in the early history of photochemistry.

He proposed a correction to the Gregorian calendar, making years that are multiples of 4000 not leap years, thus reducing the average length of the calendar year from 365.2425 days to 365.24225. Although this is closer to the mean tropical year of 365.24219 days, his proposal has never been adopted because the Gregorian calendar is based on the mean time between vernal equinoxes (currently 365.2424 days).

In 1836, he was elected a foreign member of the Royal Swedish Academy of Sciences.

In 1835, the New York Sun newspaper wrote a series of satiric articles that came to be known as the Great Moon Hoax, with statements falsely attributed to Herschel about his supposed discoveries of animals living on the Moon, including batlike winged humanoids.

He married Margaret Brodie Stewart (1810–1884) on 3 March 1829 at Edinburgh and was father of the following children:

1. Caroline Emilia Elizabeth Herschel (31 March 1830 – 29 Jan 1909), who married Alexander Hamilton-Gordon
2. Isabella Herschel (5 June 1831 – 1893)
3. Sir William James Herschel, 2nd Bt. (9 January 1833 – 1917),
4. Margaret Louisa Herschel (1834–1861), an accomplished artist
5. Prof. Alexander Stewart Herschel (1836–1907), FRS
6. Col. John Herschel FRS, FRAS, (1837–1921) surveyor
7. Marie Sophie Herschel (1839–1929)
8. Amelia Herschel (1841–1926) married Sir Thomas Francis Wade, diplomat and sinologist
9. Julia Edith Herschel (1842–1933) married on 4 June 1878 to Captain (later Admiral) John Fiot Lee Pearse Maclear
10. Matilda Rose Herschel (1844–1914)
11. Francisca Herschel (1846–1932)
12. Constance Ann Herschel (1855–20 June 1939)

On his death at Collingwood, his home near Hawkhurst in Kent, he was given a national funeral and buried in Westminster Abbey.
