14 March 1867 – 27 December 1948
Marie von Sivers was born to an aristocratic family in Włocławek Poland, then part of Imperial 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. She was the second wife of Rudolf Steiner and one of his closest colleagues from the very start.
After Dr Steiner’s death Marie Steiner’s main work was in the publication of his many papers and with the Eurythmy section at the Goetheanum. As a member of the Vorstand she was heavily involved in the dramas that eventuated in the split. In 1948, Ehrenfried Pfeiffer wrote about her after her death.
