Cornelia Froboess (born 28 October 1943, Wriezen) is a German actress and a teen idol of the 1950s and early 1960s. During that time, Froboess appeared in many musical films, especially after the rock and roll wave had hit Germany. In those comedy films, she would often portray the typical Berliner Göre (brat from Berlin) who craves independence from her strict parents.
As Conny Froboess she had her first hit record in 1951, aged eight, with a song written by her father. "Pack die Badehose ein" (Pack your swimsuit") is a cheery tune about a group of children going swimming on a hot summer's day at Wannsee. The title of the song has become a set phrase and synonym for going swimming easily recognized even by speakers of German who have never heard of the song.Source: Wikipedia
