Problem: Background: Carl August Nielsen (Danish: [ka:l 'nelsn]; 9 June 1865 - 3 October 1931) was a Danish musician, conductor and violinist, widely recognized as his country's most prominent composer. Brought up by poor but musically talented parents on the island of Funen, he demonstrated his musical abilities at an early age. He initially played in a military band before attending the Royal Danish Academy of Music in Copenhagen from 1884 until December 1886.
Context: While travelling, Nielsen discovered and then turned against Richard Wagner's music dramas, heard many of Europe's leading orchestras and soloists and sharpened his opinions on both music and the visual arts. Although he revered the music of Bach and Mozart, he remained ambivalent about much 19th-century music. In 1891 he met the composer and pianist Ferruccio Busoni in Leipzig; they were to maintain a correspondence for over thirty years. Shortly after arriving in Paris in early March 1891 Nielsen met the Danish sculptor Anne Marie Brodersen, who was also travelling on a scholarship. They toured Italy together and married in St Mark's English Church, Florence, on 10 May 1891 before returning to Denmark. According to Fanning, their relationship was not only a "love match", but also a "meeting of minds"; Anne Marie was a gifted artist and a "strong-willed and modern-minded woman, determined to forge her own career". This determination would strain the Nielsens' marriage, as Anne Marie would spend months away from home during the 1890s and 1900s, leaving Carl, who was susceptible to opportunities with other ladies, to raise their three young children in addition to composing and fulfilling his duties at the Royal Theatre. Nielsen sublimated his anger and frustration over his marriage in a number of musical works, most notably between 1897 and 1904, a period which he sometimes called his "psychological" period. Fanning writes, "At this time his interest in the driving forces behind human personality crystallized in the opera Saul and David and the Second Symphony (The Four Temperaments) and the cantatas Hymnus amoris and Sovnen". Carl suggested divorce in March 1905 and had considered moving to Germany for a fresh start, but despite several extended periods of separation the Nielsens remained married for the remainder of the composer's life. Nielsen had five children, two of them illegitimate. He had already fathered a son, Carl August Nielsen, in January 1888, before he met Anne Marie. In 1912, an illegitimate daughter was born - Rachel Siegmann, about whom Anne Marie never learned. With his wife Nielsen had two daughters and a son. Irmelin, the elder daughter, studied music theory with her father and in December 1919 married Eggert Moller (1893-1978), a medical doctor who became a professor at the University of Copenhagen and director of the polyclinic at the National Hospital. The younger daughter Anne Marie, who graduated from the Copenhagen Academy of Arts, married the Hungarian violinist Emil Telmanyi (1892-1988) in 1918; he contributed to the promotion of Nielsen's music, both as a violinist and a conductor. Nielsen's son, Hans Borge, was handicapped as a result of meningitis and spent most of his life away from the family. He died near Kolding in 1956.
Question: How many children he have
Answer: Nielsen had five children, two of them illegitimate.

Background: Stereolab were an English-French avant-pop band from London, formed in 1990 by Tim Gane (guitar/keyboards) and Laetitia Sadier (vocals/keyboards/guitar) who both remained at the songwriting helm across many line-up changes. Other long-time members included Mary Hansen (backing vocals/keyboards/guitar), who joined in 1992 and remained in the line-up until her accidental death in 2002, and Andy Ramsay (drums), who joined in 1993 and is still in the official line-up. Sean O'Hagan of the High Llamas was a member from 1993 to 1994, and continued appearing on later records for occasional guest appearances. The group's music combined influences from krautrock, lounge and 1960s pop music.
Context: Stereolab's music is politically and philosophically charged. Laetitia Sadier, who writes the group's lyrics, said that her inspiration was most recently her anger towards the Iraq War. The Surrealist and Situationist cultural and political movements were also influences, as noted by Sadier and Gane in a 1999 Salon.com interview. Stewart Mason commented in an AllMusic review that the lyrics from the 1997 song "Miss Modular" "sound influenced by the Situationist theory of the 'spectacle'." Critics have noted Marxist allusions in the band's lyrics, and have gone so far as to call the band members themselves Marxist. Music journalist Simon Reynolds commented that Sadier's lyrics tend to lean towards Marxist social commentary rather than "affairs of the heart". "Ping Pong", a 1994 single included on the album Mars Audiac Quintet, was noted for its alleged Marxist lyrics. In the song, Sadier sings "about capitalism's cruel cycles of slump and recovery" with lyrics that constitute "a plainspoken explanation of one of the central tenets of Marxian economic analysis" (said critics Simon Reynolds and Stewart Mason, respectively). Band members have resisted attempts to link the group and its music to Marxism. In a 1999 interview, Gane stated that "none of us are Marxists ... I've never even read Marx." Gane said that although Sadier's lyrics touch on political topics, they do not cross the line into "sloganeering". Sadier also said that she had read very little Marx. In contrast, Cornelius Castoriadis, a radical political philosopher but strong critic of Marxism, has been cited as a marking influence in Sadier's thinking. The name of her side project, Monade, and its debut album title, Socialisme ou Barbarie, are also references to the work of Castoriadis. Stereolab's album and song titles occasionally reference avant-garde political groups and artists. Gane said that the title of their 1999 album Cobra and Phases Group Play Voltage in the Milky Night contains the names of two Surrealist organisations, "CoBrA" and "Phases Group", "Brakhage", the title of the first song on the 1997 album Dots and Loops, is a nod to experimental filmmaker Stan Brakhage. Other examples are the 1992 compilation Switched On, named after Wendy Carlos' 1968 album Switched on Bach, and the 1992 single "John Cage Bubblegum", named after experimental composer John Cage.
