Sergei O. Prokofieff (1954-2014) was born in Moscow, where he studied fine arts and painting at the Moscow School of Art. At an early age he encountered the work of Rudolf Steiner and quickly realized that his life would be dedicated to the Christian path of esoteric knowledge. He wrote his first book, Rudolf Steiner and the Founding of the New Mysteries, while living in Soviet Russia, and it was published in English in 1994. After the fall of Communism, he helped establish the Anthroposophical Society in Russia. In 2001, he became a member of the Executive Council of the General Anthroposophical Society at the Goetheanum in Switzerland. More than 30 of his books have been translated into English. Sergei Prokofieff passed away in Dornach, Switzerland.
