Betty Mars was a French singer and actress. By age 16 she was appearing in revues and spent the 1960s travelling as a lead performer in shows around Europe and the Americas. In 1971 she was spotted singing in cabaret by composer Frédéric Botton, who offered her the song “Monsieur l’étranger” which became her first recording. Mars continued recording through the 1970s. She starred in the 1975 softcore film “Emilienne”, which was seen as an obvious attempt to cash in on the “Emmanuelle“ phenomenon of the time. Into the 1980s, Mars tended to drift out of sight as fashions changed and her performance style fell out of favour.
Tormented by emotional and financial problems, Mars jumped from a window of her flat on 31 January 1989. She died three weeks later, on 20 February, aged 44.
