Polish anthroposophist and the second wife of Rudolf Steiner and one of his closest colleagues. She made a great contribution to the development of anthroposophy, particularly in her work on the renewal of the performing arts (eurythmy, speech and drama), and the editing and publishing of Rudolf Steiner’s literary estate.
Marie von Sivers was born of an aristocratic family in W?oc?awek, Poland, then part of Russia. She was well-educated and was fluent in Russian, German, English, French and Italian. She studied theater and recitation with several teachers in Europe.
Marie von Sivers collaborated with Steiner for the rest of Steiner’s life and carried his work beyond his death in 1925 until her own death in 1948. She accompanied him and helped him as secretary, translator, editor, and organizer of his lecture tours and other public activities. She assisted Steiner’s work with her own resources and in 1908 founded the Philosophical-Theosophical Press (later Philosophical-Anthroposophical) to publish Steiner’s work.
On 24 December 1914, Marie von Sivers married Rudolf Steiner. Anna Eunicke Steiner, Steiner’s first wife, had died in 1911. Beginning in 1914, Steiner drew up a succession of wills naming Marie Steiner-von Sivers as heir to his entire work and property and his successor in the leadership of the anthroposophical movement.
Marie Steiner-von Sivers died on 27 December 1948 at age 81 in Beatenberg, Switzerland.
