Herbert Hans Koepf (1914-2007) was a hands-on farmer in Germany who went on to receive a PhD in agriculture, specialising in soil science. In 1962, after 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. Then in 1970 he moved to Emerson College in the UK, running the biodynamic agriculture course every year until 1990. He was also head of the Agriculture Section at the Goetheanum in Switzerland.
'Herbert Koepf was a pioneer of biodynamics in Germany and elsewhere. This is a short handbook summarising his findings with a wealth of practical advice ... Books like this remind us of the parallels between plant and human health, and also all the rhythms of life as a process in time regulated by both the earthly and cosmic environments.' -- Scientific & Medical Network Review
