During the last two decades of the nineteenth century, the Austrian-born Rudolf Steiner (1861-1925) became a respected and well-published scientific, literary, and philosophical scholar, particularly known for his work on Goethe's scientific writings. After the turn of the century, he began to develop his earlier philosophical principles into an approach to methodical research of psychological and spiritual phenomena.

His multi-faceted genius has led to innovative and holistic approaches in medicine, science, education (Waldorf schools), special education, philosophy, religion, economics, agriculture (Bio-Dynamic method), architecture, drama, the new art of eurythmy, and other fields. In 1925 he founded the General Anthroposophical Society, which today has branches throughout the world. More information can be found at the Rudolf Steiner Archive
