Problem: The answer to the question: What is the first name of the person who discovered that, in the last months of Messiaen's life, he had been composing a concerto for four musicians? is inside the article: Messiaen's next work was the large-scale La Transfiguration de Notre Seigneur Jésus-Christ. The composition occupied him from 1965 to 1969 and the musicians employed include a 100-voice ten-part choir, seven solo instruments and large orchestra. Its fourteen movements are a meditation on the story of Christ's Transfiguration. Shortly after its completion, Messiaen received a commission from Alice Tully for a work to celebrate the U.S. bicentennial.  He arranged a visit to the US in spring 1972, and was inspired by Bryce Canyon in Utah, where he observed the canyon's distinctive colours and birdsong. The twelve-movement orchestral piece Des canyons aux étoiles... was the result, first performed in 1974 in New York.In 1971, he was asked to compose a piece for the Paris Opéra. While reluctant to undertake such a major project, he was persuaded in 1975 to accept the commission and began work on his Saint-François d'Assise. The composition was intensive (he also wrote his own libretto) and occupied him from 1975 to 1979; the orchestration was carried out from 1979 until 1983. Messiaen preferred to describe the final work as a "spectacle" rather than an opera. It was first performed in 1983. Some commentators at the time thought that the opera would be his valediction (at times Messiaen himself believed so), but he continued to compose. In 1984 he published a major collection of organ pieces, Livre du Saint Sacrement; other works include birdsong pieces for solo piano, and works for piano with orchestra.In the summer of 1978, Messiaen retired from teaching at the Conservatoire. He was promoted to the highest rank of the Légion d'honneur, the Grand-Croix, in 1987. An operation prevented his participation in the celebration of his 70th birthday in 1978, but in 1988 tributes for Messiaen's 80th included a complete performance in London's Royal Festival Hall of St. François, which the composer attended, and Erato's publication of a seventeen-CD collection of Messiaen's music including a disc of the composer in..., can you guess it ?

Problem: The answer to the question: What was the full name of the person who replaced Richard on the throne? is inside the article: When Richard II was crowned in 1377, he led a procession from the Tower to Westminster Abbey. This tradition began in at least the early 14th century and lasted until 1660. During the Peasants' Revolt of 1381 the Tower of London was besieged with the King inside. When Richard rode out to meet with Wat Tyler, the rebel leader, a crowd broke into the castle without meeting resistance and looted the Jewel House. The Archbishop of Canterbury, Simon Sudbury, took refuge in St John's Chapel, hoping the mob would respect the sanctuary. However, he was taken away and beheaded on Tower Hill. Six years later there was again civil unrest, and Richard spent Christmas in the security of the Tower rather than Windsor as was more usual. When Henry Bolingbroke returned from exile in 1399, Richard was imprisoned in the White Tower. He abdicated and was replaced on the throne by Bolingbroke, who became King Henry IV. In the 15th century, there was little building work at the Tower of London, yet the castle still remained important as a place of refuge. When supporters of the late Richard II attempted a coup, Henry IV found safety in the Tower of London. During this period, the castle also held many distinguished prisoners. The heir to the Scottish throne, later King James I of Scotland, was kidnapped while journeying to France in 1406 and held in the Tower. The reign of Henry V (1413–1422) renewed England's fortune in the Hundred Years' War against France. As a result of Henry's victories, such as the Battle of Agincourt, many high-status prisoners were held in the Tower of London until they were ransomed.Much of the latter half of the 15th century was occupied by the Wars of the Roses between the claimants to the throne, the houses of Lancaster and York. The castle was once again besieged in 1460, this time by a Yorkist force. The Tower was damaged by artillery fire but only surrendered when Henry VI was captured at the Battle of Northampton. With the help of Richard Neville, 16th Earl of Warwick (nicknamed "the Kingmaker")..., can you guess it ?

Problem: The answer to the question: What is the first name of the father of the boy who was supposed to propose to a woman who helped him after he slipped? is inside the article: Nannerl herself was an   apt pupil, no less quick to learn than her brother, and was playing the keyboard with striking virtuosity by the time she was eleven. In that year, 1762, Leopold brought the children to Munich to play before Maximilian III Joseph, Elector of Bavaria. Leopold then took the entire family to Vienna, on a trip that lasted for three months. He had secured invitations from several noble patrons, and within three days of arriving the children were playing at the palace of Count Collalto. Among those present was the Viennese Treasury councillor and future prime minister Karl von Zinzendorf, who noted in his diary that "a little boy, said to be only five-and-a-half years old [Wolfgang was actually nearly seven], played the harpsichord". After an appearance before the Imperial Vice-Chancellor, the Mozarts were invited to the royal court, where the Empress Maria Theresa tested Wolfgang's abilities by requiring him to play with the keyboard covered. During this court visit Wolfgang met the Archduchess Maria Antonia, the future Queen Marie Antoinette of France, who was two months his senior. Mozart's biographer Eric Blom recounts an anecdote of how the Archduchess helped Wolfgang when he slipped on the polished floor; she is supposed to have received a proposal of marriage in return.As the Mozarts began to be noticed by the Viennese aristocracy, they were often required to give several performances during a single day. They were well rewarded for this activity—at the end of their first hectic week in Vienna, Leopold was able to send home the equivalent of more than two years' salary. Their schedule was interrupted when Wolfgang fell ill with scarlet fever, and their former momentum was not regained. Nevertheless, the visit left Leopold eager to pursue further opportunities for social and financial success. On their return to Salzburg, Wolfgang played the harpsichord and violin at a birthday concert for the archbishop, to the evident astonishment of those present., can you guess it ?
