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.

Input: Consider Input: Passage: In 1958 Poulenc embarked on a collaboration with his old friend Cocteau, in an operatic version of the latter's 1930 monodrama La Voix humaine. The work was produced in February 1959 at the Opéra-Comique, under Cocteau's direction, with Duval as the tragic deserted woman speaking to her former lover by telephone. In May Poulenc's 60th birthday was marked, a few months late, by his last concert with Bernac before the latter's retirement from public performance.Poulenc visited the US in 1960 and 1961. Among his works given during these trips were the American premiere of La Voix humaine at Carnegie Hall in New York, with Duval, and the world premiere of his Gloria, a large-scale work for soprano, four-part mixed chorus and orchestra, conducted in Boston by Charles Munch. In 1961 Poulenc published a book about Chabrier, a 187-page study of which a reviewer wrote in the 1980s, "he writes with love and insight of a composer whose views he shared on matters like the primacy of melody and the essential seriousness of humour." The works of Poulenc's last twelve months included Sept répons des ténèbres for voices and orchestra, the Clarinet Sonata and the Oboe Sonata.On 30 January 1963, at his flat opposite the Jardin du Luxembourg, Poulenc suffered a fatal heart attack. His funeral was at the nearby church of Saint-Sulpice. In compliance with his wishes, none of his music was performed; Marcel Dupré played works by Bach on the grand organ of the church. Poulenc was buried at Père Lachaise Cemetery, alongside his family. 
Question: What is the last name of the person whose last concert with Bernac before his retirement from public performance marked his birthday late?


Output: Poulenc.
