Steiner studied journalism in Budapest and travelled extensively in Austria, Germany and Italy, where she encountered Futurism and was influenced by Orphism. In 1927 she moved to Paris, where she met and married István Beöthy. In 1931 she was among the founding members of the group Abstraction-Création, alongside artists including Arp, Gabo, Mondrian and Vantongerloo. Her work encompassed illustrations, textile design and compositions characterised by the use of colour, contrast and simple geometric forms, which became an inspiration for the future development of Op Art. In 1934 she abandoned her artistic activity, returning to the art scene only in the 1960s, after her husband's death.
