After the end of her first marriage in 1906, Hennings was an itinerant performer, travelling over much of the European continent. She was a performer at the Cabaret Simplizissimus in Munich, when she met Ball in 1913. At the time, Hennings was already a published poet, whose works had appeared in left-wing publications called Pan and Die Aktion. In 1913 she also published a short poetry collection called Ether Poems, or Äthergedichte in German. Later, Hennings was a collaborator to the magazine Revolution, which was founded by Ball and Hans Leybold.
