Input: Consider Input: Passage: Manchester has a notable place in the history of Marxism and left-wing politics; being the subject of Friedrich Engels' work The Condition of the Working Class in England in 1844; Engels spent much of his life in and around Manchester, and when Karl Marx visited Manchester, they met at Chetham's Library. The economics books Marx was reading at the time can be seen in the library, as can the window seat where Marx and Engels would meet. The first Trades Union Congress was held in Manchester (at the Mechanics' Institute, David Street), from 2 to 6 June 1868. Manchester was an important cradle of the Labour Party and the Suffragette Movement.At that time, it seemed a place in which anything could happen—new industrial processes, new ways of thinking (the Manchester School, promoting free trade and laissez-faire), new classes or groups in society, new religious sects, and new forms of labour organisation. It attracted educated visitors from all parts of Britain and Europe. A saying capturing this sense of innovation survives today: "What Manchester does today, the rest of the world does tomorrow." Manchester's golden age was perhaps the last quarter of the 19th century. Many of the great public buildings (including Manchester Town Hall) date from then. The city's cosmopolitan atmosphere contributed to a vibrant culture, which included the Hallé Orchestra. In 1889, when county councils were created in England, the municipal borough became a county borough with even greater autonomy.
Although the Industrial Revolution brought wealth to the city, it also brought poverty and squalor to a large part of the population. Historian Simon Schama noted that "Manchester was the very best and the very worst taken to terrifying extremes, a new kind of city in the world; the chimneys of industrial suburbs greeting you with columns of smoke". An American visitor taken to Manchester's blackspots saw "wretched, defrauded, oppressed, crushed human nature, lying and bleeding fragments".The number of cotton mills in Manchester itself reached a peak of 108 in 1853. Thereafter the number began to decline and Manchester was surpassed as the largest centre of cotton spinning by Bolton in the 1850s and Oldham in the 1860s. However, this period of decline coincided with the rise of the city as the financial centre of the region. Manchester continued to process cotton, and in 1913, 65% of the world's cotton was processed in the area. The First World War interrupted access to the export markets. Cotton processing in other parts of the world increased, often on machines produced in Manchester. Manchester suffered greatly from the Great Depression and the underlying structural changes that began to supplant the old industries, including textile manufacture. 
Question: What place attracted educated visitors from all parts of Britain and Europe?

Output: Manchester.


Input: Consider Input: Passage: 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. 
Question: Who played the keyboard with striking virtuosity?

Output: Wolfgang.
