Margrit Kennedy was head of the Research Department Ecology and Energy in the framework of the International Building Exhibition of Berlin. As early as 1982, she recognized in this context a flaw in our monetary system by discovering a major obstacle with regard to implementing economic measures to the necessary extent. This was the beginning of a now 30 year long search for alternatives to the current monetary system. Her book Interest and Inflation Free Money has been translated into 22 languages. Her book Regional Currencies: a New Path to Sustainable Prosperity (co-written by Bernard Lietaer) serves as the theoretical foundation for over 70 initiatives in Germany — of which 30 have already issued a regional currency — and has been published in French and Spanish. In lectures and seminars, she conveys how the monetary system, as a focal point of our economic problems, can become an instrument that serves us rather than masters us.
