Marie Magdalene Bull née Midling (25 October 1827 – 17 July 1907) was a Norwegian actress who took a leading role in the first performance at Bergen's Det norske Theater.

Following her marriage to the theatre's conductor Edvard Storm Bull, in 1851 she gave up acting to become a photographer, opening her own studio.

[3] She grew up in Bergen where, on 25 July 1849, she saw an advertisement in the paper announcing the opening of Det norske Theater, the country's first Norwegian-speaking theatre.

She immediately applied and was taken on as an actress and dancer, performing at the theatre's first rehearsal with an invited audience on 21 November 1849 and at the official opening on 2 January 1850.

One of the oldest, dated 1855, is a photograph of Johannes Brun performing in Hun skal debutere.
