Dagmar Julie Augusta Hansen (12 November 1871 – 13 April 1959), a Danish cabaret-singer and stage-performer, became a national sensation as Denmark's first "pin-up girl".

Daniel Krum, the Ballet Director of the Royal Danish Theatre asked her (aged 10) to join the company; however, her father refused to allow it.

[1] She made her stage debut at the age of 11 in the role of a child general in the fantasy play Tommeliden at the Casino Theater in Copenhagen.

Her performances won critical praise in the press for her enjoyable singing voice, charming presence, and well-developed figure.

She sang a repertoire specially written for her (including pieces such as Aah, Dagmar and Linger Longer Loo) and performed in small revealing costumes which she sewed herself.

[1] She also posed as a nude model for several Danish artists' masterworks, including Julius Paulsen's 1887 painting, Adam og Eva,[3] and Vilhelm Bissen's sculpture from 1890, En Jægerinde.
