Danish singer, Grethe Ingmann, born Clemmensen on June 17, 1938, began her career at age 17 as part of the Malihini Hawaiians pop quartet. She later performed with Danish guitarist Jørn Grauengaard and his trio before meeting her future husband, Jørgen Ingmann, in 1955. The couple married in 1956 and formed the duo Grethe og Jørgen Ingmann. Their breakthrough came in 1963 when they won the Eurovision Song Contest representing Denmark with "Dansevise" (Dancing tune), a jazz waltz composed by Otto Francker with lyrics by Sejr Volmer-Sørensen. This victory marked the first time a duo won the contest and the first Scandinavian winner. In 1965, Grethe Ingmann participated in the German Schlager Contest with "Sommerwind", which later became an international hit in its English version, sung by Frank Sinatra. The couple continued their musical career until their divorce in 1975. As a solo artist, Grethe Ingmann participated in several Danish pre-selections for the Eurovision Song Contest, notably entering the Dansk Melodi Grand Prix in 1979 with "Alt er skønt", which tied for first place but ultimately placed second after a re-vote. The couple remarried in the 1980s. Grethe Ingmann died from liver cancer on August 18, 1990, at the age of 52, becoming the first Eurovision winner to pass away.
