Some context: 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.
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.

Some context: Amy Winehouse was born in Chase Farm Hospital, in north London, to Jewish parents. Her father, Mitchell "Mitch" Winehouse, was a window panel installer and then a taxi driver; and her mother, Janis Winehouse (nee Seaton), was a pharmacist. Winehouse's ancestors were Russian Jewish and Polish Jewish immigrants to London. Amy had an older brother, Alex (born 1979), and the family lived in London's Southgate area, where she attended Osidge Primary School.
Winehouse's battles with substance abuse were the subject of much media attention. In 2005, she went through a period of drinking, heavy drug use, and weight loss. People who saw her during the end of that year and early 2006 reported a rebound that coincided with the writing of Back to Black. Her family believes that the mid-2006 death of her grandmother, who was a stabilising influence, set her off into addiction. In August 2007, Winehouse cancelled a number of shows in the UK and Europe, citing exhaustion and ill health. She was hospitalised during this period for what was reported as an overdose of heroin, ecstasy, cocaine, ketamine and alcohol. In various interviews, she admitted to having problems with self-harm, depression, and eating disorders.  Winehouse told a magazine that the drugs were to blame for her hospitalisation and that "I really thought that it was over for me then." Soon afterward, Winehouse's father commented that when he had made public statements regarding her problems he was using the media because it seemed the only way to get through to her. In an interview with The Album Chart Show on British television, Winehouse said she was manic depressive and not alcoholic, adding that that sounded like "an alcoholic in denial." A US reporter writes that Winehouse was a "victim of mental illness in a society that doesn't understand or respond to mental illness with great effectiveness."  In December 2007, Winehouse's spokesman reported that the singer was in a physician-supervised programme and was channelling her difficulties by writing a lot of music. The British tabloid The Sun posted a video of a woman, alleged to be Winehouse, apparently smoking crack cocaine and speaking of having taken ecstasy and valium. Winehouse's father moved in with her, and Island Records, her record label, announced the abandonment of plans for an American promotion campaign on her behalf. In late January 2008, Winehouse reportedly entered a rehabilitation facility for a two-week treatment program.  On 23 January 2008, the video was passed on to the Metropolitan Police, who questioned her on 5 February. No charges were brought. On 26 March 2008, Winehouse's spokesman said she was "doing well." Her record company reportedly believed that her recovery remained fragile. By late April 2008, her erratic behaviour, including an allegation of assault, caused fear that her drug rehabilitation efforts had been unsuccessful, leading to efforts by Winehouse's father and manager to seek assistance in having her involuntarily committed. Her dishevelled appearance during and after a scheduled club night in September sparked new rumours of a relapse. Photographers were quoted as saying she appeared to have cuts on her legs and arms.  According to her physician, Winehouse quit illegal substances in 2008. In an October 2010 interview, speaking of her decision to quit drugs, Winehouse said, "I literally woke up one day and was like, 'I don't want to do this any more'." Drinking alcohol emerged as a problem with Winehouse abstaining for a few weeks then lapsing. The physician said that Winehouse was treated with Librium for alcohol withdrawal and anxiety, and underwent psychological and psychiatric evaluations in 2010, but refused psychological therapy.
