Rudolf Steiner (1861-1925) called his spiritual philosophy 'anthroposophy', meaning 'wisdom of the human being'. As a highly developed seer, he based his work on direct knowledge and perception of spiritual dimensions. He initiated a modern and universal 'science of spirit', accessible to anyone willing to exercise clear and unprejudiced thinking.

From his spiritual investigations Steiner provided suggestions for the renewal of many activities, including education (both general and special), agriculture, medicine, economics, architecture, science, philosophy, religion and the arts. Today there are thousands of schools, clinics, farms and other organizations involved in practical work based on his principles.

His many published works feature his research into the spiritual nature of the human being, the evolution of the world and humanity, and methods of personal development. Steiner wrote some 30 books and delivered over 6,000 lectures across Europe. In 1924 he founded the General Anthroposophical Society, which today has branches throughout the world.

Sergei O. Prokofieff (1954-2014) studied Fine Arts and Painting at the Moscow School of Art. He encountered the work of Rudolf Steiner in his youth, and soon decided to devote his life to it. He became active as an author and lecturer in 1982, and helped found the Anthroposophical Society in his native Russia in 1991.

In Easter 2001 he was appointed a member of the Executive Council of the General Anthroposophical Society in Dornach, Switzerland, a position he held until his death. A popular speaker, he wrote numerous books and articles that are published in many languages.
