Bernard Charbonneu died in April 1996 at the age of 85. Already in 1937 the first "reflexio ecologique" ever published in France, was his manifesto "le sentiment de la nature, force revolutionnaire". After World War II he joined Jacques EIlul, professor at the University of Bordeaux in order to create a movement of ecological thinking. Both had to fight the resistance of the scientific community. While Ellul chose to coIlaborate with American universities, Bernard retired to the solitude of the Pyrenean mountains to write and meditate. Several of his numerous books were published in 1973, among others "The System and the Chaos".
