Frédéric Joliot-Curie
The period of the Cold War was for the Movement the most rich in operations, influence and effect. The Movement participated in the 1949 "Congrès mondial des Partisans de la Paix" in Paris, at which the World Peace Council was created. The leadership was given to the intellectual and scientist Frédéric Joliot-Curie. The Movement organised a massive campaign of support in France for the Stockholm appeal which gathered millions of signatures, including that of Jacques Chirac. The Stockholm campaign marked the apogee of the Movement in France.
