Question: Which year did the founder of Regius Professor of Surgery die?

full_context: Document 1: Regius Professor of Medicine (Oxford): The Regius Professor of Medicine is an appointment held at the University of Oxford. The chair was founded by Henry VIII of England by 1546, and until the 20th century the title was Regius Professor of Physic. Henry VIII established five Regius Professorships in the University, the others being the Regius chairs of Divinity, Civil Law, Hebrew and Greek.
Document 2: 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 3: Murdoch Cameron: Murdoch Cameron (31 March 1847 – 28 April 1930) was Regius Professor of Obstetrics and Gynaecology at the University of Glasgow from 1894 to 1926. He was a pioneer of the Caesarean section under modern antiseptic conditions, becoming world famous after the success of his first such operation in 1888, at what was then the Glasgow Lying-in Hospital and Dispensary, now the Princess Royal Maternity Hospital, an institution he was deeply involved with. He was honorary President of the first international Congress on Obstetrics and Gynaecology, in 1892. His son Samuel James Cameron followed in his footsteps, becoming Reguis Professor of Midwifery at Glasgow in the 1930s.
Document 4: 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 5: Robert Jameson: As Regius Professor of Natural History at the University of Edinburgh for fifty years, Jameson is notable for his advanced scholarship, his superb museum collection and for his tuition of Charles Darwin. Jameson was not at his best in the lecture theatre however, and, for the first half of his career, he grappled with his predecessor John Walker's perverse "Neptunian" geological theories. Darwin attended Robert Jameson's natural history course at the University of Edinburgh in his teenage years, learning about stratigraphic geology and assisting with the collections of the Museum of Edinburgh University, then one of the largest in Europe. At Jameson's Wernerian Natural History Association, the young Charles Darwin saw John James Audubon give a demonstration of his method of using wires to prop up birds to draw or paint them in natural positions. Robert Jameson was the great-uncle of Sir Leander Starr Jameson, Bt, KCMG, CB, British colonial official and inspiration for the "Jameson Raid".
Document 6: 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 7: 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 8: King George III Museum: The King George III Museum was a museum within King's College London, England between 1843 and 1927 which held the collections of scientific instruments of George III as well as eminent nineteenth-century scientists including Sir Charles Wheatstone and Charles Babbage. The collection of scientific and mathematical instruments assembled by George III, after whom the museum is named, was donated to the university by Queen Victoria in 1841, and the museum was opened by Albert, Prince Consort on 1 July 1843. The museum was located within the King's Building designed by Sir Robert Smirke. It counted among its collections the unfinished prototype of the Difference Engine No. 1, designed by Charles Babbage, who is considered a "father of the computer". The museum closed in 1926, and much of its collections were transferred on loan to the Science Museum, London.
Document 9: Regius Professor of English Language and Literature (Glasgow): The Regius Chair of English Language and Literature at the University of Glasgow was founded in 1861 by Queen Victoria, and is the only Regius Professorship in the Faculty of Arts.
Document 10: 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 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: 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 13: William Sharp (surgeon): William Sharp (1729 – 17 March 1810) was an English physician reported to have acted as surgeon to King George III. With his brother Granville Sharp, he was an active supporter of the early campaign against slavery in Britain.
Document 14: Regius Professor of Surgery (Glasgow): The Regius Chair of Surgery at the University of Glasgow was founded in 1815 by King George III, who also established the Chairs of Chemistry and Natural History.
Document 15: Thomas George Roddick: Thomas George Roddick attended the Model and Normal Schools in Truro, Nova Scotia and graduated from the Medical Faculty of McGill University in 1868 with the highest honours, winning the Holmes Gold Medal and Final Prize. From 1868 to 1874, he was Assistant House Surgeon at the Montreal General Hospital. In 1872, he was appointed Lecturer on Hygiene at McGill University. He was appointed a Demonstrator of Anatomy in 1874 and in 1875 was named Professor of Clinical Surgery. Earlier in 1877, Roddick traveled to Edinburgh to witness Joseph Lister's medical antiseptic system. Roddick returned to Montreal later that year and introduced Joseph Lister's antiseptic system, primarily his 'carbolic spray,' revolutionizing the way medicine was practiced in Montreal's Hospitals.
