Rudolf Steiner (1861-1925) was born in the small village of Kraljevec, Austro-Hungarian Empire (now in Croatia), where he grew up (see right). As a young man, he lived in Weimar and Berlin, where he became a well-published scientific, literary, and philosophical scholar, known especially for his work with Goethe's scientific writings. At the beginning of the twentieth century, he began to develop his early philosophical principles into an approach to systematic research into psychological and spiritual phenomena. Formally beginning his spiritual teaching career under the auspices of the Theosophical Society, Steiner came to use the term Anthroposophy (and spiritual science) for his philosophy, spiritual research, and findings. The influence of Steiner's multifaceted genius has led to innovative and holistic approaches in medicine, various therapies, philosophy, religious renewal, Waldorf education, education for special needs, threefold economics, biodynamic agriculture, Goethean science, architecture, and the arts of drama, speech, and eurythmy. In 1924, Rudolf Steiner founded the General Anthroposophical Society, which today has branches throughout the world. He died in Dornach, Switzerland. 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. Simon Blaxland de Lange has for many years worked as an educator for people with special needs. He is also a prolific writer and translator and an amateur musician and gardener. Blaxland de Lange helped establish Pericles Translations and Research, Pericles Training and Work (for adults with special needs), and the Pericles Theatre Company. Together with Dr Vivian Law, he cofounded the Humanities Research Group in 1997 and the British group of the Humanities Section of the School of Spiritual Science in 1998. He met Owen Barfield in 1979, and has been a student of his work for the past thirty years.
