Manfred Klett | Born in 1933. He studied agriculture in Hohenheim, did research on fertilizing in relation to food quality at the Institute for Biodynamic Research in Darmstadt. In 1968 he took on the Dottenfelderhof near Frankfurt, Germany, together with four other families to form the first farm community. He became in 1974 co-founder of the farm school Dottenfelderhof and in 1980 of the agricultural community Dottenfelderhof – an attempt to open the farm spiritually, legally and economically to the social environment. He trained many young apprentices and continued farming for nearly 20 years. Between 1987 and 2001 he led the Agricultural Department at the Goetheanum.
