UK Experimental Circle formed

As a direct result of the enthusiasm emerging from Carl Mirbt’s lecture at the World Conference on Spiritual Science the Experimental Circle in the UK was formed for those who were Anthroposophists in the AAF. The Experimental Circle of Anthroposophical Farmers and Gardeners in Great Britain and other English-speaking Countries, to give it its full name, was run by Daniel Dunlop, George Adams, Maurice Wood and Carl Mirbt. They hold monthly meetings for years. Carl Mirbt moves to the UK at the invitation of Marna Pease at Bray On Thames. 

David Clements says this:

When Carl Alexander Mirbt (later changed to Meir) brought the Bio-Dynamic impulse to this country in 1929 at D.N. Dunlop‘s initiative, the organisation was straight way formed called the Anthroposophical Agricultural Foundation (the name Bio-Dynamic had not yet been thought of) and at the same time the “Experimental Circle of Anthroposophical Farmers and Gardeners” was formed. The latter was composed of those members of the Foundation who were Anthroposophists.
