Input: Consider Input: Passage: After graduation, Shostakovich initially embarked on a dual career as concert pianist and composer, but his dry style of playing was often unappreciated (his American biographer, Laurel Fay, comments on his "emotional restraint" and "riveting rhythmic drive"). He nevertheless won an "honorable mention" at the First International Chopin Piano Competition in Warsaw in 1927. He attributed the disappointment at the competition to suffering from appendicitis and the jury being all-Polish. He had his appendix removed in April 1927. After the competition Shostakovich met the conductor Bruno Walter, who was so impressed by the composer's First Symphony that he conducted it at its Berlin premiere later that year. Leopold Stokowski was equally impressed and gave the work its U.S. premiere the following year in Philadelphia and also made the work's first recording.
Shostakovich concentrated on composition thereafter and soon limited his performances primarily to those of his own works. In 1927 he wrote his Second Symphony (subtitled To October), a patriotic piece with a great pro-Soviet choral finale. Owing to its experimental nature, as with the subsequent Third Symphony, it was not critically acclaimed with the enthusiasm given to the First.
1927 also marked the beginning of Shostakovich's relationship with Ivan Sollertinsky, who remained his closest friend until the latter's death in 1944. Sollertinsky introduced the composer to the music of Mahler, which had a strong influence on his music from the Fourth Symphony onwards.
While writing the Second Symphony, Shostakovich also began work on his satirical opera The Nose, based on the story by Nikolai Gogol. In June 1929, against the composer's own wishes, the opera was given a concert performance; it was ferociously attacked by the Russian Association of Proletarian Musicians (RAPM). Its stage premiere on 18 January 1930 opened to generally poor reviews and widespread incomprehension among musicians.In the late 1920s and early 1930s, Shostakovich worked at TRAM, a proletarian youth theatre. Although he did little work in this post, it shielded him from ideological attack. Much of this period was spent writing his opera, Lady Macbeth of the Mtsensk District, which was first performed in 1934. It was immediately successful, on both popular and official levels. It was described as "the result of the general success of Socialist construction, of the correct policy of the Party", and as an opera that "could have been written only by a Soviet composer brought up in the best tradition of Soviet culture".Shostakovich married his first wife, Nina Varzar, in 1932. Initial difficulties led to a divorce in 1935, but the couple soon remarried when Nina became pregnant with their first child, Galina. 
Question: What is the name of the composer whose First Symphony was conducted by Bruno Walter at its Berlin premiere?

Output: Shostakovich.


Input: Consider Input: Passage: The origins of the Early Netherlandish school lie in the miniature paintings of the late Gothic period.  This was first seen in manuscript illumination, which after 1380 conveyed new levels of realism, perspective and skill in rendering colour, peaking with the Limbourg brothers and the Netherlandish artist known as Hand G, to whom the most significant leaves of the Turin-Milan Hours are usually attributed. Although his identity has not been definitively established, Hand G, who contributed c. 1420, is thought to have been either Jan van Eyck or his brother Hubert. According to Georges Hulin de Loo, Hand G's contributions to the Turin-Milan Hours "constitute the most marvelous group of paintings that have ever decorated any book, and, for their period, the most astounding work known to the history of art".Jan van Eyck's use of oil as a medium was a significant development, allowing artists far greater manipulation of paint. The 16th-century art historian Giorgio Vasari claimed van Eyck invented the use of oil paint; a claim that, while exaggerated, indicates the extent to which van Eyck helped disseminate the technique. Van Eyck employed a new level of virtuosity, mainly from taking advantage of the fact that oil dries so slowly; this gave him more time and more scope for blending and mixing layers of different pigments, and his technique was quickly adopted and refined by both Robert Campin and Rogier van der Weyden. These three artists are considered the first rank and most influential of the early generation of Early Netherlandish painters. Their influence was felt across northern Europe, from Bohemia and Poland in the east to Austria and Swabia in the south. 
Question: What are the last names of the three artists who are considered the first rank and most influential of the early generation of Early Netherlandish painters?

Output: Van Eyck.


Input: Consider Input: Passage: Aaliyah Dana Haughton was born on January 16, 1979, in Brooklyn, New York, and was the younger child of Diane and Michael "Miguel" Haughton (1951–2012). She was of African-American descent, and had Native American (Oneida) heritage from a grandmother. Her name has been described as a female version of the Arabic "Ali", but the original Jewish name "Aliya (Hebrew: אליה)" is derived from the Hebrew word "aliyah (Hebrew: עלייה)", meaning "highest, most exalted one, the best." The singer was highly fond of her Semitic name, calling it "beautiful" and asserting she was "very proud of it" and strove to live up to her name every day. Aaliyah's mother enrolled Aaliyah in voice lessons at an early age. She started performing at weddings, church choir and charity events. When Aaliyah was five years old, her family moved to Detroit, Michigan, where she was reared along with her older brother, Rashad. She attended a Catholic school, Gesu Elementary, where in first grade she was cast in the stage play Annie, which inspired her to become an entertainer. In Detroit, her father began working in the warehouse business, one of his brother-in-law Barry Hankerson's widening interests. Her mother stayed home and raised Aaliyah and her brother.Throughout Aaliyah’s life, she had a good relationship with Rashad, who recalled Aaliyah having a beautiful voice as a child. Aaliyah's family was very close due to the struggles of her grandparents and when they moved to Detroit, the Hankersons were ready to take them in if necessary. These same bonds led to ties in the music industry, under the Blackground Records label.Aaliyah's mother was a vocalist, and her uncle, Barry Hankerson, was an entertainment lawyer who had been married to Gladys Knight. As a child, Aaliyah traveled with Knight and worked with an agent in New York to audition for commercials and television programs, including Family Matters; she went on to appear on Star Search at the age of ten. Aaliyah chose to begin auditioning. Her mother made the decision to drop her surname. She auditioned for several record labels and at age 11 appeared in concerts alongside Knight. She had several pet animals during her childhood, including ducks, snakes and iguanas. Her cousin Jomo had a pet alligator, which Aaliyah felt was too much, remarking, "that was something I wasn't going to stroke."Her grandmother died in 1991. Years after her death, Aaliyah said her grandmother supported everyone in the family and always wanted to hear her sing, as well as admitting that she "spoiled" her and her brother Rashad. She also enjoyed Aaliyah's singing and would have Aaliyah to sing for her. Aaliyah said she thought of her grandmother whenever she fell into depression. Aaliyah's hands reminded her of her aunt, who died when she was very young and whom Aaliyah remembered as an "amazingly beautiful woman". 
Question: What is the first name of Aaliyah's mother who stayed home and raised her and her brother?


Output: Diane.
