Rudolf Steiner (b. Rudolf Joseph Lorenz Steiner, 1861-1925) was born in the small village of Kraljevec, Austro-Hungarian Empire (now in Croatia), where he grew up. 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. Gerard Wagner (1906-1999) was born in Germany and grew up in England. He began his vocation as an artist by learning from an English plein air painter before starting formal studies at the Royal College of Art in London. Beginning in 1926, he took up the challenge of a new direction in painting as initiated by Rudolf Steiner, which became the essence of his life's work for more than seventy years. Through his efforts to grasp the secrets of Steiner's training sketches for painters, Wagner succeeded in disclosing their metamorphic character and, from this, was able to develop a systematic approach to painting. Elisabeth Wagner-Koch, whom Gerard later married, became his first student in 1950, and together they established The Painting School at the Goetheanum, of which he remained the principle teacher until his death in Arlesheim, Switzerland. Rudolf Steiner's indications for an art of the future remained the impulse for Wagner's research and artistic activity throughout his life. The fruits of his research are a unique method of teaching and his archive of paintings, which continue to be a source of inspiration for the school. Wagner's wife Elisabeth cares for the archive of about 4,000 paintings. Gerard Wagner (1906-1999) was born in Germany and grew up in England.

He moved to the U.S. and graduated from Cornell University with an M.F.A. in painting. Following his first teaching stint at the University of Kansas, Peter began teaching color courses at the City University of New York in 1970. Having begun investigations into Goethe's color theory, he visited the Gerard Wagner painting school in Dornach, Switzerland. There he began training with Wagner, who asked him to teach in the school. Peter later established a painting school at the Threefold Educational Foundation in Spring Valley, New York. For the past thirty years, he has taught introductory courses in Goethe's color theory with experiments in England, Germany, Switzerland, and the U.S. Since 1992, Peter has been director of the Arteum Painting School in Dornach, Switzerland, and has held a number of exhibitions of his work in Europe and North America. Peter Selg studied medicine in Witten-Herdecke, Zurich, and Berlin and, until 2000, worked as the head physician of the juvenile psychiatry department of Herdecke Hospital in Germany. Dr. Selg is director of the Ita Wegman Institute for Basic Research into Anthroposophy (Arlesheim, Switzerland), professor of medicine at the Alanus University of Arts and Social Sciences (Germany), and co-leader of the General Anthroposophical Section at the Goetheanum. He is the author of numerous books on Rudolf Steiner, anthroposophy, medical ethics, and the development of culture and consciousness.
