I was born in 1952 in Neuwied, Germany. By training, I am a systems dynamicist. These are the people who build computer models of complex (social and physical) systems using system dynamics - a modeling language simple enough for me to understand. Computer models are next to impossible to communicate, but an unbeatable way to learn and get to the core of things. My teachers were Bill Shafer, Dennis Meadows, Barry Richmond and especially Jorgen Randers.
For communicating my ideas I've turned to scenarios more than twenty years ago. In the 1990ties I built up - with several great team mates - the Scenario Unit of the World Business Council for Sustainable Development. I ran the Unit for a number of years. I've had the good fortune to learn all that I know about scenarios from Betty Sue Flowers and Ged Davis.
Since about the year 2000, I have worked as a freelancer worldwide with companies, universities, foundations and students. I design and deliver workshops and projects, give speeches and write.
Lately I've become a visiting professor at the Business School of Lausanne where I teach a course on scenario planning.
I have lived in Wales, the United States, Norway, France, Germany and Switzerland.
I don't have any biological kids, but have helped raise a fair number of them over the years - and all of them still talk to me - so far.
