Alice and Ellen Kessler, the famous twin performers who shared stages with Frank Sinatra and Fred Astaire, passed away on Monday at the age of 89 through medical aid at their home near Munich. According to Bild, the sisters “chose to end their lives together… expressing that they no longer wished to continue living.”

Born in 1936, the twins rose to fame in the 1950s and 1960s. They represented West Germany in the 1959 Eurovision Song Contest, placing eighth. Their popularity grew with frequent appearances on the variety show Studio Uno, and a Playboy cover propelled them to international stardom.

Their deaths came under Germany’s medically assisted dying law, legal since 2019, which allows individuals to administer life-ending medication themselves if deemed responsible and acting of their own free will. Authorities confirmed there was no foul play, and the sisters had requested to be placed together in a single urn.

Tributes poured in after the news. Radio Monte Carlo honored them on Instagram: “Alice and Ellen Kessler left together, just as they lived: inseparable… In Italy, they became celebrities as the ‘legs of the nation,’ icons of elegance and stage presence since the Fifties.”

The tribute continued: “A unique artistic couple, capable of leaving an indelible imprint on the collective imagination.” Alice and Ellen Kessler will be remembered for their lasting impact on European music, dance, and television.
