Excerpt from "Rogue Agent - The Cercle and the 6I in the Private Cold War 1951 - 1991" - by David Teacher
“In August 1959, ['Cees'] Van den Heuvel set up a foundation for research into human ecology based in the Hague. The title is indicative, if not conclusive: in 1955, the CIA had founded a Society for the Study of Human Ecology which changed name in 1961 to become the Human Ecology Fund. Both American organizations were funding conduits for the CIA's MK-ULTRA programme of research into mind control and brainwashing. Van den Heuvel's human ecology foundation would soon change titles to the Oost-West Stichting (East-West Foundation), which received funding from the BVD. According to an Italian secret service (SIFAR) report dated October 1963, the BVD funded a meeting in Barbizon near Paris on 5th - 8th October 1961 where "the participants decided to unite all efforts and initiatives of the struggle against Communism within a new organization and place these on a serious and expert footing."
