Ehrenfried Pfeiffer
Ehrenfried Pfeiffer (19 February 1899 in Munich, Germany – 30 November 1961 in Spring Valley, New York, United States) was a German scientist, soil scientist, leading advocate of biodynamic agriculture, anthroposophist and student of Rudolf Steiner.
Ehrenfried Pfeiffer began work with Rudolf Steiner in 1920 to develop and install special diffuse stage lighting for eurythmy performances on the stage of the first Goetheanum. After Steiner's death in 1925, Pfeiffer worked in the private research laboratory at the Goetheanum in Dornach, (Switzerland). He became manager and director of the 800-acre (3.2 km2) experimental biodynamic Loverendale farm in Domburg in the Netherlands. This farm was set up to carry out some of the agricultural studies of the Goetheanum laboratory. The work of testing and developing Rudolf Steiner's Agriculture Course of 1924 was an international enterprise coordinated by Pfeiffer at the Natural Science Section of the Goetheanum. Pfeiffer’s most influential book 'Bio-Dynamic Farming and Gardening' was published in 1938 simultaneously in at least five languages, English, German, Dutch, French, and Italian. The following year, and just months before the outbreak of World War II, Pfeiffer ran Britain's first biodynamics conference, the Betteshanger Summer School and Conference, at the estate of Lord Northbourne in Kent. Pfeiffer's Betteshanger Conference is regarded as the 'missing link' between biodynamic agriculture and organic farming because the following year (1940) its host, [Lord Northbourne], published his manifesto of organic farming 'Look to the Land' in which he coined the term 'organic farming'.
