Trille Bodil Nielsen, also Gudrun Bodil Nielsen, (1945–2016) was a Danish singer, guitarist and women's rights activist. In the 1960s, she began to sing mainly traditional folk songs and children's songs. After singing Jesper Jensen's controversial song "Øjet" (The Eye) on the TV programme Musikalske venner (Musical Friends) in 1970, she gained immediate popularity. A few years later, her album Hej søster (Hi Sister) with her own songs about the problems faced by women saw the beginning of a successful career as both a songwriter and a singer. She suddenly completely retired from the limelight in 1988, thereafter concentrating on her humanitarian and cultural interests. In particular, she produced programmes for children on Danish television.[1][2][3]
