Editing Carl Nielsen (section)

=== Marriage and children ===
While travelling, Nielsen discovered and then turned against [[Richard Wagner]]'s [[music drama]]s, 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 [[Johann Sebastian Bach|Bach]] and [[Wolfgang Amadeus Mozart|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.{{sfn|Grimley|2005|pp=212–213}} 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.{{sfn|Lawson|1997|p=58}} 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".{{sfn|Fanning|2001|p=889}} This determination would strain the Nielsens' marriage, as Anne Marie would spend months away from home during the 1890s and 1900s, leaving Carl, who pursued extramarital affairs with other women in her absence, to raise their three young children in addition to composing and fulfilling his duties at the Royal Theatre.<ref name="CNS-crisis" />

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.{{sfn|Fanning|2001|p=889}} Fanning writes, "At this time his interest in the driving forces behind human personality crystallized in the opera ''[[Saul og David|Saul and David]]'' and the [[Symphony No. 2 (Nielsen)|Second Symphony (''The Four Temperaments'')]] and the cantatas {{lang|la|[[Hymnus amoris]]}} and {{lang|da|[[Søvnen]]}}".{{sfn|Fanning|2001|p=889}} Carl suggested divorce in March 1905 and had considered moving to Germany for a fresh start,{{sfn|Lawson|1997|p=104}} but despite several extended periods of separation the Nielsens remained married for the remainder of the composer's life.<ref name="CNS-crisis" />

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&nbsp;– Rachel Siegmann, about whom Anne Marie never learned.<ref name="CNS-crisis" /> 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 Møller (1893–1978), a medical doctor who became a professor at the [[University of Copenhagen]] and director of the [[polyclinic]] at the [[Rigshospitalet|National Hospital]]. The younger daughter [[Anne Marie Telmányi|Anne Marie]], who graduated from the [[Royal Danish Academy of Fine Arts|Copenhagen Academy of Arts]], married the Hungarian violinist [[Emil Telmányi]] (1892–1988) in 1918; he contributed to the promotion of Nielsen's music, both as a violinist and a conductor. Nielsen's son, Hans Børge, was disabled as a result of [[meningitis]] and spent most of his life away from the family. He died near Kolding in 1956.<ref name="CNS-family" />
