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.
