Acting
Christa Päffgen (16 October 1938 – 18 July 1988), known by her stage name Nico, was a German singer, songwriter, actress and model. She had roles in several films, including Federico Fellini's La Dolce Vita (1960) and Andy Warhol's Chelsea Girls (1966). Reviewer Richard Goldstein describes Nico as "half goddess, half icicle" and writes that her distinctive voice "sounds something like a cello getting up in the morning".
