Born in Dresden, Goslar came from a banking family and worked towards a career as a dancer from an early age.
She travelled with the group to the US in late autumn 1936, in order to make a new (but futile) start there with the Peppermill at the beginning of 1937.
[2] Goslar performed in nightclubs and went to Hollywood in 1943, where she founded her own troupe with which she undertook many extensive tours of the US and later Europe.
She also worked as a dance instructor, teaching Marilyn Monroe of whom she was one of the few attendees to her funerals on 8 August 1962 and Gower Champion, among others.
In 1987, Goslar appeared in Rosa von Praunheim's film Dolly, Lotte and Maria.
