Soeur Sourire ("Sister Smile") was the nickname of Soeur Luc-Gabrielle, a Dominican Catholic nun born Jeanne Deckers in French-speaking Laeken, Belgium. In the convent, she wrote, sang, and performed her own songs, and her superiors encouraged her to record an album. She became internationally famous in 1963 with the release of her single "Dominique," which topped the charts in the USA and many other countries. In English-speaking parts of the world, she was known by the stage name The Singing Nun. In 1966, she was the subject of a Hollywood biopic of that name. By 1985, she was dead from an overdose of barbiturates, having left the convent and lost a long battle with alcohol, tranquilizers, and the tax authorities.
