Trivia

On May 21, 1956, at the first Eurovision Song Contest, held at the Teatro Kursaal in Lugano, she performed the song "Il est là" ("He's Here") and finished second.

In April 1967, while driving towards Duranville, Eure, on the N13, she skidded off the road and crashed into a tree. Dauberson was thrown out of her seat and through the windscreen while in the passenger's seat her companion, actress Nicole Berger, suffered both a fractured skull and a crushed rib cage. Dauberson and Berger were rushed to hospital, where Berger died from her injuries. Dauberson never fully recovered emotionally or physically from the crash, which ended her career as a singer. She died in 1979, at the age of 54.
