Question: In what year did the leader of schools in the Royal Palace die

full_context: Document 1: Queen Victoria: At the time of her accession, the government was led by the Whig prime minister Lord Melbourne, who at once became a powerful influence on the politically inexperienced Queen, who relied on him for advice. Charles Greville supposed that the widowed and childless Melbourne was "passionately fond of her as he might be of his daughter if he had one", and Victoria probably saw him as a father figure. Her coronation took place on 28 June 1838 at Westminster Abbey. Over 400,000 visitors came to London for the celebrations. She became the first sovereign to take up residence at Buckingham Palace and inherited the revenues of the duchies of Lancaster and Cornwall as well as being granted a civil list allowance of £385,000 per year. Financially prudent, she paid off her father's debts.
Document 2: Queen Victoria: Victoria was the daughter of Prince Edward, Duke of Kent and Strathearn, the fourth son of King George III. Both the Duke of Kent and King George III died in 1820, and Victoria was raised under close supervision by her German-born mother Princess Victoria of Saxe-Coburg-Saalfeld. She inherited the throne aged 18, after her father's three elder brothers had all died, leaving no surviving legitimate children. The United Kingdom was already an established constitutional monarchy, in which the sovereign held relatively little direct political power. Privately, Victoria attempted to influence government policy and ministerial appointments; publicly, she became a national icon who was identified with strict standards of personal morality.
Document 3: Age of Enlightenment: In England, the Royal Society of London also played a significant role in the public sphere and the spread of Enlightenment ideas. It was founded by a group of independent scientists and given a royal charter in 1662. The Society played a large role in spreading Robert Boyle's experimental philosophy around Europe, and acted as a clearinghouse for intellectual correspondence and exchange. Boyle was "a founder of the experimental world in which scientists now live and operate," and his method based knowledge on experimentation, which had to be witnessed to provide proper empirical legitimacy. This is where the Royal Society came into play: witnessing had to be a "collective act", and the Royal Society's assembly rooms were ideal locations for relatively public demonstrations. However, not just any witness was considered to be credible; "Oxford professors were accounted more reliable witnesses than Oxfordshire peasants." Two factors were taken into account: a witness's knowledge in the area; and a witness's "moral constitution". In other words, only civil society were considered for Boyle's public.
Document 4: Age of Enlightenment: The history of Academies in France during the Enlightenment begins with the Academy of Science, founded in 1635 in Paris. It was closely tied to the French state, acting as an extension of a government seriously lacking in scientists. It helped promote and organize new disciplines, and it trained new scientists. It also contributed to the enhancement of scientists' social status, considering them to be the "most useful of all citizens". Academies demonstrate the rising interest in science along with its increasing secularization, as evidenced by the small number of clerics who were members (13 percent). The presence of the French academies in the public sphere cannot be attributed to their membership; although the majority of their members were bourgeois, the exclusive institution was only open to elite Parisian scholars. They perceived themselves as "interpreters of the sciences for the people". For example, it was with this in mind that academicians took it upon themselves to disprove the popular pseudo-science of mesmerism.
Document 5: Queen Victoria: During Victoria's first pregnancy in 1840, in the first few months of the marriage, 18-year-old Edward Oxford attempted to assassinate her while she was riding in a carriage with Prince Albert on her way to visit her mother. Oxford fired twice, but either both bullets missed or, as he later claimed, the guns had no shot. He was tried for high treason and found guilty, but was acquitted on the grounds of insanity. In the immediate aftermath of the attack, Victoria's popularity soared, mitigating residual discontent over the Hastings affair and the bedchamber crisis. Her daughter, also named Victoria, was born on 21 November 1840. The Queen hated being pregnant, viewed breast-feeding with disgust, and thought newborn babies were ugly. Nevertheless, over the following seventeen years, she and Albert had a further eight children: Albert Edward, Prince of Wales (b. 1841), Alice (b. 1843), Alfred (b. 1844), Helena (b. 1846), Louise (b. 1848), Arthur (b. 1850), Leopold (b. 1853) and Beatrice (b. 1857).
Document 6: Queen Victoria: Though queen, as an unmarried young woman Victoria was required by social convention to live with her mother, despite their differences over the Kensington System and her mother's continued reliance on Conroy. Her mother was consigned to a remote apartment in Buckingham Palace, and Victoria often refused to see her. When Victoria complained to Melbourne that her mother's close proximity promised "torment for many years", Melbourne sympathised but said it could be avoided by marriage, which Victoria called a "schocking  [sic] alternative". She showed interest in Albert's education for the future role he would have to play as her husband, but she resisted attempts to rush her into wedlock.
Document 7: Royal Academy of Arts: The Royal Academy of Arts was founded through a personal act of King George III on 10 December 1768 with a mission to promote the arts of design in Britain through education and exhibition. The motive in founding the Academy was twofold: to raise the professional status of the artist by establishing a sound system of training and expert judgement in the arts, and to arrange the exhibition of contemporary works of art attaining an appropriate standard of excellence. Supporters wanted to foster a national school of art and to encourage appreciation and interest among the public based on recognised canons of good taste.
Document 8: London: London is home to many museums, galleries, and other institutions, many of which are free of admission charges and are major tourist attractions as well as playing a research role. The first of these to be established was the British Museum in Bloomsbury, in 1753. Originally containing antiquities, natural history specimens and the national library, the museum now has 7 million artefacts from around the globe. In 1824 the National Gallery was founded to house the British national collection of Western paintings; this now occupies a prominent position in Trafalgar Square.
Document 9: Paris: For centuries, Paris has attracted artists from around the world, who arrive in the city to educate themselves and to seek inspiration from its vast pool of artistic resources and galleries. As a result, Paris has acquired a reputation as the "City of Art". Italian artists were a profound influence on the development of art in Paris in the 16th and 17th centuries, particularly in sculpture and reliefs. Painting and sculpture became the pride of the French monarchy and the French royals commissioned many Parisian artists to adorn their palaces during the French Baroque and Classicism era. Sculptors such as Girardon, Coysevox and Coustou acquired reputations as the finest artists in the royal court in 17th-century France. Pierre Mignard became the first painter to King Louis XIV during this period. In 1648, the Académie royale de peinture et de sculpture (Royal Academy of Painting and Sculpture) was established to accommodate for the dramatic interest in art in the capital. This served as France's top art school until 1793.
Document 10: Royal Institute of British Architects: The Royal Institute of British Architects (RIBA) is a professional body for architects primarily in the United Kingdom, but also internationally, founded for the advancement of architecture under its charter granted in 1837 and Supplemental Charter granted in 1971.
Document 11: Queen Victoria: At birth, Victoria was fifth in the line of succession after her father and his three older brothers: the Prince Regent, the Duke of York, and the Duke of Clarence (later William IV). The Prince Regent and the Duke of York were estranged from their wives, who were both past child-bearing age, so the two eldest brothers were unlikely to have any further children. The Dukes of Kent and Clarence married on the same day 12 months before Victoria's birth, but both of Clarence's daughters (born in 1819 and 1820 respectively) died as infants. Victoria's grandfather and father died in 1820, within a week of each other, and the Duke of York died in 1827. On the death of her uncle George IV in 1830, Victoria became heiress presumptive to her next surviving uncle, William IV. The Regency Act 1830 made special provision for the Duchess of Kent to act as regent in case William died while Victoria was still a minor. King William distrusted the Duchess's capacity to be regent, and in 1836 declared in her presence that he wanted to live until Victoria's 18th birthday, so that a regency could be avoided.
Document 12: Great Exhibition: The Great Exhibition of the Works of Industry of All Nations was organized by Prince Albert, Henry Cole, Francis Henry, George Wallis, Charles Dilke and other members of the Royal Society for the Encouragement of Arts, Manufactures and Commerce as a celebration of modern industrial technology and design. It was arguably a response to the highly successful French Industrial Exposition of 1844: indeed, its prime motive was for Britain to make ``clear to the world its role as industrial leader ''. Prince Albert, Queen Victoria's consort, was an enthusiastic promoter of the self - financing exhibition; the government was persuaded to form the Royal Commission for the Exhibition of 1851 to establish the viability of hosting such an exhibition. Queen Victoria and her family visited three times. Although the Great Exhibition was a platform on which countries from around the world could display their achievements, Britain sought to prove its own superiority. The British exhibits at the Great Exhibition`` held the lead in almost every field where strength, durability, utility and quality were concerned, whether in iron and steel, machinery or textiles.'' Britain also sought to provide the world with the hope of a better future. Europe had just struggled through ``two difficult decades of political and social upheaval, ''and now Britain hoped to show that technology, particularly its own, was the key to a better future.
Document 13: Queen Victoria: In 1830, the Duchess of Kent and Conroy took Victoria across the centre of England to visit the Malvern Hills, stopping at towns and great country houses along the way. Similar journeys to other parts of England and Wales were taken in 1832, 1833, 1834 and 1835. To the King's annoyance, Victoria was enthusiastically welcomed in each of the stops. William compared the journeys to royal progresses and was concerned that they portrayed Victoria as his rival rather than his heiress presumptive. Victoria disliked the trips; the constant round of public appearances made her tired and ill, and there was little time for her to rest. She objected on the grounds of the King's disapproval, but her mother dismissed his complaints as motivated by jealousy, and forced Victoria to continue the tours. At Ramsgate in October 1835, Victoria contracted a severe fever, which Conroy initially dismissed as a childish pretence. While Victoria was ill, Conroy and the Duchess unsuccessfully badgered her to make Conroy her private secretary. As a teenager, Victoria resisted persistent attempts by her mother and Conroy to appoint him to her staff. Once queen, she banned him from her presence, but he remained in her mother's household.
Document 14: Queen Victoria: Victoria's father was Prince Edward, Duke of Kent and Strathearn, the fourth son of the reigning King of the United Kingdom, George III. Until 1817, Edward's niece, Princess Charlotte of Wales, was the only legitimate grandchild of George III. Her death in 1817 precipitated a succession crisis that brought pressure on the Duke of Kent and his unmarried brothers to marry and have children. In 1818 he married Princess Victoria of Saxe-Coburg-Saalfeld, a widowed German princess with two children—Carl (1804–1856) and Feodora (1807–1872)—by her first marriage to the Prince of Leiningen. Her brother Leopold was Princess Charlotte's widower. The Duke and Duchess of Kent's only child, Victoria, was born at 4.15 a.m. on 24 May 1819 at Kensington Palace in London.
Document 15: Collection of the National Gallery, London: The National Gallery is the primary British national public art gallery, sited on Trafalgar Square, in central London. It is home to one of the world's greatest collections of Western European paintings. Founded in 1824, from an initial purchase of 36 paintings by the British Government, its collections have since grown to about 2,300 paintings by roughly 750 artists dating from the mid-13th century to 1900, most of which are on display. This page lists some of the highlights of the collection.
