Herbert H. Koepf

Herbert Hans Koepf (1914–2007) was a hands-on farmer in Germany who went on to receive a PhD in agriculture, specializing in soil science. In 1962, following the death of Ehrenfried Pfeiffer, with whom Koepf had worked closely, he became director of Pfeiffer's biodynamic research laboratory in Spring Valley, New York. In 1970, Koepf moved to Emerson College in the UK, leading the biodynamic agriculture course each year until 1990. He was also head of the Agriculture Department at the Goetheanum in Switzerland.
