Charles François was born in Belgium in 1922, and studied consular and commercial sciences at Brussels Free University. After the Second World War he emigrated to the Belgian Congo, where he stayed from 1945 to 1960, at first as an administrative officer in government and later on creating and developing his own commercial business, also exercising journalism and the socio-political chronicle.

François inspired and founded the Group for the Study of Integrated Systems, Argentine National Division of the International Society for the Systems Sciences, in 1976, and was its honorary president. He was an honorary member of the International Federation for Systems Research European Systems Society, and founding editor of the International Encyclopedia of Systems and Cybernetics, editions of 1997 and 2004 in two volumes. He encouraged its work in progress in course of organization through the Bertalanffy Center of Systems and Cybernetics, member of the International Academy of Systems and Cybernetics Sciences, honorary president of the Latin American Association of Systemics, Honorary Professor of ITBA, and was a visiting professor at various universities and educational institutions in Argentina, Mexico, Perú, Colombia, Venezuela and Brasil, where he encouraged the creation of many study groups.

In 1958 he joined the Society for General Systems Research now the International Society for the Systems Sciences.
