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. Dr. Ehrenfried Pfeiffer (1899-1961) was born in Munich. He worked closely with Rudolf Steiner to test and document many of the effects of biodynamic practices. Pfeiffer visited the U.S. several times during the 1930s, and was awarded a doctorate for his groundbreaking theory of Sensitive Crystallization Processes as a blood test for detecting cancer. In 1940, he immigrated to the U.S., where he pioneered biodynamic agriculture and helped establish the Biodynamic Farming & Gardening Association. He died in Spring Valley, New York. Peter Bridgmont is involved in voice training at the Globe Theatre in London. He has been a professional actor in theater, films, and on radio and TV. In 1975 he and his wife, Barbara, opened the Chrysalis Theatre Acting School in London. George Adams (1894-1963)was born in Poland and received an honors degree in Chemistry from Cambridge University. He was a close student of Rudolf Steiner, and translated many of his lectures given to English-speaking audiences. Being a Jew, when Hitler rose to power he changed his name from Kaufmann to Adams and left Germany for England, where he continued his anthroposophic activities and scientific research. In 1935, Olive Whicher joined Adams in London and worked with him in research into mathematics and physics until his death in 1963. He translated and published numerous books, lectures, and articles.
